A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are
typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic,
most commonly derived from petrochemicals, but many are partially natural.
Molding is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or
matrix. This itself may have been made using a pattern or model of the final object.
Cooling channels are used in mold tool to reduce the temperature of the object to help molten material to solidify quickly
before the ejection. It is quite useful to increase the production rate.

Blow Mould Tool Design and Manufacturing Process for 1litre Pet BottleIOSR Journals
the concepts of Blow molding is a process used to produce hollow objects from thermoplastic. The
basic blow molding process has two fundamental phases. First, a parson (or a perform) of hot plastic resin in a
somewhat tubular shape is created. Second, compressed air is used to expand the hot perform and press it
against mould cavities. The pressure is held until the plastic cools. Blow molding process is used for which has
thin wall sections.In this thesis, blow mould design is to be done for a bottle having 0.5mm thickness. This
thickness cannot be filled in pressure injection molding. So blow molding is considered for pet bottle design.
The mould is prepared by first modeling the part, extracting core & cavity and generating CNC program. Blow
mould tool design is done in Pro/Engineer according to HASCO standards. A prototype of the pet bottle using

Experimental Validation of 3-D Printed BoltsIJMERJOURNAL
ABSTRACT: 3-D printing, which is an automated production process with layer-by-layer control, has been gaining rapid development in recent years. 3-D printing is the process by which a 3-D digital design is converted into a component by depositing material using additive processing. Three dimensional (3D) printing offers versatile possibilities for adapting the structural parameters on engineering scaffolds. These three dimensional elements were produced from Poly Lactic Acid (PLA) and Acrylonitrile butadiene Styrene (ABS)by means of fused deposition process. This work is initiated by designing a three dimensional model of an ISO standard bolt and creating a 3D printing of this model using PLA and ABS as material. Designing will be carried out using SOLIDWORKS. Later on the design is analysed on analysis software (ANSYS) for deformation, equivalent stress and shear stress. A prototype model of this bolt will be created using three dimensional printer. Shear test is performed using UTM on the bolts that are created using three dimensional printer. Each bolt material’s failure forces are noted down and shear stresses are calculated. The PLA and ABS bolts are compared with each other. They are also checked for safe limits by comparing them with their respective material properties.

FDM Modeled Polymer Tooling for Plastic Injection MoldingIJAMSE Journal
Rapid Prototyping is being accepted globally by industries for its potential in saving on process time and cost. Rapid Tooling helps Rapid Prototyping grow beyond its conventional Feel & Fit status to Feel Fit Function status and is increasingly becoming popular. However, potential of rapid prototyping for normal
production run is still not being realized. In that situation Rapid Tooling becomes a viable alternative. The greatest opportunity for rapid tooling implementation is the use of Additive Manufacturing (AM) technology. Further, polymer based direct rapid tooling provide large cost reduction and can also be
readily accessible by industries. With the advances in materials along with the new access and low cost plastic based- AM equipment, direct use Polymer Rapid Tools (PRTs) would be a far more advantageous option in creating injection molds for low and highly flexible production. However, the use of polymer
based direct rapid tooling by industries is curtailed due to the issues with the dimensional stability of the polymer based rapid tooling molds. Apart from dimensional tolerances, there are also issues with the life of these polymer based mold as they wear fast and are also not able to sustain high injection pressures in an Injection molding machine. Another, major problem with the polymer based rapid tooling is the poor thermal conductivity of polymeric materials due to which there is an increase in the cooling time and ultimately leading to decrease in productivity. Therefore, before proposing polymer based rapid tooling as a solution to industries to cut down the product development time and bring down the costs, a thorough study of the issues related to the same is imperative. This paper investigates the dimensional accuracy of striker component produced by ABS mold inserts. For dimensional accuracy a reverse engineering technique3D scanning is used which is compared with CAD file and inspected with COMET plus software. Further, the outputs are validated with vernier caliper. The mold insert is manufactured by Fused Deposition Modeling (FDM) technology which is used on injection molding machine

Process optimization of pressure die casting to eliminate defect using cae so...eSAT Journals
Abstract
Die Casting is the manufacturing process by which a liquid material is pressurized in to the mould, which contains a hallow
cavity of the desired shape, and then molten metal is allowed to solidify. The solidified part is known as casting which is ejected
or broken out to complete the process. Objective in this project is to develop tools, dies and gating system. Identify defects such as
gas defects, shrinkage cavities, and mould material defects, pouring material defects, metallurgical defects etc. and take measures
to reduce flaws by using CAE software. To reduce the amount airs entrapped in the mould by changing the gating system, runner
and overflow location and optimize the gating system and process parameters for best quality product and improved productivity.
Defects can be formed easily at critical location during pressure die casting of aluminium alloy part. It has defective effect on the
casting. Mould filling and solidification process of a part was simulated using Z-cast software.
Key Words: Casting, HPDC, Z-cast, CAE Software, Simulation.
Design and Manufacturing of Pet Bottle DieIJMTST Journal
A bottle is a rigid container with a neck that is narrower than the body and a "mouth. Bottles are often made of glass, clay, plastic, aluminum or other impervious materials, and typically used to store liquids such as water, milk, soft drinks, ink, chemicals and etc. A device applied in the bottling line to seal the mouth of a bottle is termed an external bottle cap; the bottle has developed over millennia of use, with some of the earliest examples appearing in China, Phoenicia, Rome and Crete. Bottles are often recycled according to the SPI recycling code for the material. Some regions have a legally mandated deposit which is refunded after returning the bottle to the retailer. Blow molding process is pretty much comparable with injection molding but the only difference is that, in this case, heated liquid plastic vertically pours out of barrel-like pot into molten tubes. The vacuum part is created. Most bottles are formed with this type of molding. Hot plastic resin is combined with a pressurized gas to fill and press the mold cavity, forming a hollow part.
3D modeling is done by pro-engineer.

The largest part of the engine is cylinder block. The upper section of the cylinder block consists of cylinders and pistons. Crankcase is supported by the crankshaft and it is placed in the lower section. Aluminum cylinder blocks are lighter than the cast-iron cylinder blocks of the same size. Cylinder block, pistons, cylinder head, crankshaft and connecting rods are the major elements of the engine. IC engine cooling uses either a liquid or gas to remove the unnecessary heat from an internal combustion engine. For special purpose and small engines, air cooling makes for a lightweight and relatively simple system, if we use the materials with better waste heat dissipation it will help in achieving better efficiencies and long life of the engine.

he present paper deals with the effect of volume fraction of fillers on the thermal Properties of polymer composites. This work sees an opportunity of enhancement on insulation capability of a typical fiber reinforced polymer composite. To validate this mathematical model, a set of epoxy based composites, with fiber content ranging 4.38 to 20.10% of volume fractions have been prepared by simple hand lay-up technique. For preparing the composite, natural fiber i.e. Pine apple leaf fibers are incorporated in Epoxy Resin. Thermal conductivities of these composite samples are measured as per ASTM standard E-1530 by using the Unitherm™ Model 2022 tester, which operates on the double guarded heat flow principle at the temperature ranging from 30˚C to 150˚C. And also the Specific Heat of the powdered samples are measured by using Differential Scanning Calorimeter (DSC). By using the MATLAB the numerical analysis is carried out to find the value of Thermal Diffusivity with varying temperatures. It was observed that the thermal diffusivity varies with fiber concentration, but the variation of thermal diffusivity with varying temperature was not so significant.

With the growing quantity of pictures users distribute from node to node social networks, retaining confidentiality has turn out to be a foremost predicament, as declared by a latest wave of made known occurrences wherever users unintentionally shared individual profile. In radiance of these occurrences made necessitate of tools to assist users organize access to their distributed data is evident. In the direction of speak to this requirement, we suggest an Adaptive Privacy Policy forecast (A3P) scheme to facilitate users compile confidentiality settings for their pictures. We observe the responsibility of communal context, picture content, and metadata as possible sign of users’ confidentiality preference. We recommend a two-level structure which according to the user’s obtainable times past on the site, establishs the most excellent obtainable confidentiality policy for the user’s pictures being uploaded. Our solution relies on an image classification framework for image categories which may be associated with similar policies, and on a policy prediction algorithm to automatically generate a policy for each newly uploaded image, also according to users’ social features. Over time, the generated policies will follow the evolution of users’ privacy attitude. We provide the results of our extensive evaluation over 5,000 policies, which demonstrate the effectiveness of our system, with prediction accuracies over 90 percent.

Our method chains the public examination and well-organized user revocation and also some nice properties, such as confidently, efficiency, countability and traceability of secure group user invalidation. Finally, the security and experimental analysis show that,compared with its appropriate methods our scheme is also safe and well-organized.
Ijricit 01-006 a secluded approval on clould storage proceedingsIjripublishers Ijri
In available practically proven Data clustering practices for eradicating same copies of replicated data, Data de-replication is one of significant mechanisms, and has been extensively practiced in cloud storage to diminish the quantity of storage space and accumulate bandwidth. To guard the privacy of responsive data though sustaining de-replication, the convergent encryption technique has been anticipated to encrypt the data before redirecting. For an improvised shielding of data safety, this paper formulates the primary effort to formally speak to the problem of approved data de-replication. Diverse from conventional de-replication systems, the discrepancy privileges of users are auxiliary considered in replica verification besides the data itself. In this we introduce several novel de-replication structural methods in sustaining approved replica test in hybrid cloud architecture. Safety examination demonstrates that our system is protected in terms of the description particular in the anticipated security model. As an evidence of perception, we execute a model of our anticipated approved replica check method and perform test-bed research using our model. We demonstrate that our anticipated approved replica check method acquire minimal overhead evaluated to standard procedures.

Ijri ece-01-02 image enhancement aided denoising using dual tree complex wave...Ijripublishers Ijri
This paper presents a novel way to reduce noise introduced or exacerbated by image enhancement methods, in particular algorithms based on the random spray sampling technique, but not only. According to the nature of sprays, output images of spray-based methods tend to exhibit noise with unknown statistical distribution. To avoid inappropriate assumptions on the statistical characteristics of noise, a different one is made. In fact, the non-enhanced image is considered to be either free of noise or affected by non-perceivable levels of noise. Taking advantage of the higher sensitivity of the human visual system to changes in brightness, the analysis can be limited to the luma channel of both the non-enhanced and enhanced image. Also, given the importance of directional content in human vision, the analysis is performed through the dual-tree complex wavelet transform , lanczos interpolator and edge preserving smoothing filters. Unlike the discrete wavelet transform, the DTWCT allows for distinction of data directionality in the transform space. For each level of the transform, the standard deviation of the non-enhanced image coefficients is computed across the six orientations of the DTWCT, then it is normalized.
Keywords: dual-tree complex wavelet transform (DTWCT), lanczos interpolator, edge preserving smoothing filters.

Ijri te-03-011 performance testing of vortex tubes with variable parametersIjripublishers Ijri
Conventional refrigeration system is a type of refrigeration systems which are costly; noisy, harmful gases released from a machine based on application of this type of system and it is required more maintenance. So, we need to go for unconventional refrigeration systems like vortex tube refrigeration system, which produce less vibrations and which require less maintenance and which are noiseless. It is required for our mechanical engineers to look for enhancing the performance of such vortex tubes. So as a part of my project work, I have chosen various sizes of vortex tubes and test their performances for finding out optimum performance. We will be testing the performance of vortex tubes with different ‘l/d’ ratios and different cold fractions, with different pressures and different nozzle sizes.

Ijri te-03-013 modeling and thermal analysis of air-conditioner evaporatorIjripublishers Ijri
Air conditioning evaporator works by absorb heat from the area (medium) that need to be cooled. It does that by maintaining the evaporator coil at low temperature and pressure than the surrounding air. Since, the AC evaporator coil contains refrigerant that absorbs heat from the surrounding air, the refrigerant temperature must be lower than the air.
In our project we have modeling an air-cooled evaporator for a home 1.5ton air conditioner. Presently the material used for coils is copper and the material used for fins is copper or aluminum. A 3D model of the evaporator is done in parametric software Pro/Engineer.
To validate the temperatures and other thermal quantities like flux and gradient, thermal analysis is done on the evaporator coil by applying properties copper and suitable material like aluminum. And also we are varying inside cooling fluid Hydrocarbon (HC) and Hydro chloroflouro carbon (HCFC).The best material for the evaporator of our design can be checked by comparing the results.
Thermal analysis is done in ANSYS.
Ijri te-03-012 design and optimization of water cool condenser for central ai...Ijripublishers Ijri
Water-cooled chiller systems have typically been designed around entering condenser water temperatures of 85°F with a Optimization of Water - Cooled Chiller – Cooling Tower Combinations The warm water leaving the chilled water coils is pumped to the evaporator of the chiller, where the unwanted heat from the building is transferred by the latent heat of vaporization of the refrigerant. The compressor of the chiller then compresses the refrigerant to a higher pressure, adding the heat of compression in the process. The high pressure refrigerant then moves to the economical condenser water flow of 3.0 USGPM/ton and a 10°F denser, where the unwanted heat is rerange. In recent years, there has been considerable debate on the merits of designing around lower condenser water flow rates with a higher range in order to improve system lifecycle costs. However, two other parameters must also be considered in any analysis - approach and design wet bulb. The question to be answered is: What nominal condenser water flow rate and approach is best from a first cost standpoint as well as from a full load energy standpoint at any given wet bulb.

http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Computer Aided Design (CAD) is a technique in
which problem solving will be done in the combina-
tion of man and machine for high precision work
flow.
Abstract
A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are
typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic,
most commonly derived from petrochemicals, but many are partially natural.
Molding is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or
matrix. This itself may have been made using a pattern or model of the final object.
Cooling channels are used in mold tool to reduce the temperature of the object to help molten material to solidify quickly
before the ejection. It is quite useful to increase the production rate.
The aim of this project work is to design mold structure and optimize cooling channel system to reduce effect of warpage
of remote control top panel.
Literature survey and data collection will be done to understand working process of cooling channels, effects of warpage
on plastic part’s, mold optimization.
3D model of remote control top panel will be prepared and die design calculations will be done to model the entire mold
step.
Assembly of complete mold will be prepared for further process.
Analysis will be carried out on mold cooling channel’s for evaluation and Analysis will be done on different model’s to
obtain optimum structure and cooling channel system.
Conclusion will be mode according to the obtained results

Computer Aided Design is an interactive process,
where the exchange of information between the
designer and the computer is made as simple and
effective as possible. Computer aided design en-
compasses a wide variety of computer based meth-
odologies and tools for engineering activity plan-
ning, analysis, detailing, drafting, construction,
manufacturing, monitoring, management, process
control and maintenance. CAD is more concerned
with the use of computer-based tools to support the
entire life cycle of engineering system.
Introduction To Creo Parametric 2.0 (Creo 2.0)
CREO PARAMETRIC is one of the most popular PLM
software founded by Parametric Technology Corpo-
ration which consists of CAD/CAM/CAE. So that
designer can easily check their part/product design
compatibility with FEM and CAM segments and
also they can check plastic flow for injection mold-
ings parts to reduce production/component errors.
CREO PARAMETRIC is completely feature based
modeling tool with ribbon mode which is very easy
to understand by the users.
Summary of capabilities
Like any software it is continually being developed
to include new functionality. The details below aim
to outline the scope of capabilities to give an over-
view rather than giving specific details on the indi-
vidual functionality of the product.
Engineering Design
Creo parametric 2.0 offers a range of tools to enable
the generation of a complete digital representation
of the product being designed. In addition to the
general geometry tools there is also the ability to
generate geometry of other integrated design disci-
plines such as industrial and standard pipe work
and complete wiring definitions. Tools are also
available to support collaborative development.
A number of concept design tools that provide up-
front Industrial Design concepts can then be used
in the downstream process of engineering the prod-
uct. These range from conceptual Industrial design
sketches, reverse engineering with point cloud data
and comprehensive freeform surface tools.
Manufacturing
By using the fundamental abilities of the software
with regards to the single data source principle, it
provides a rich set of tools in the manufacturing en-
vironment in the form of tooling design and simu-
lated CNC machining and output.
Tooling options cover specialty tools for molding,
die-casting and progressive tooling design.

Injection Moulding
In manufacturing processes Injection moulding
plays a crucial role for producing plastic compo-
nents by using thermo plastic and thermo setting.
After completion of product design as per client re-
quirement done by an engineer, molds are prepared
by tool maker. For less number of components Alu-
minum is the better option. For large production
better to use steel alloys to maintain good surface
finish, dimensional stability. Maximum of compo-
nents are made by thermo plastic which are recy-
cled (or) reusable.
plasticsMaterial is fed into a heated barrel, mixed,
and forced into a mold cavity where it cools and
hardens to the configuration of the mold cavity
Commonly open top components are produced in
injection molding which is having minimum thick-
ness of 0.5mm, for good quality of product the wall
thickness should be more than 2mm.
For remote control panel better to use recycled poly-
propelene due to good impact resistence, low cost
and eco-friendly and it has good structural stability.
Process Characteristics
• Utilizes a ram or screw-type plunger to force
molten plastic material into a mold cavity
• Produces a solid or open-ended shape which has
conformed to the contour of the mold
• Uses thermoplastic or thermoset materials
• Produces a parting line, sprue, and gate marks
• Ejector pin marks are usually present
Injection molding is used to create many things
such as wire spools, packaging, bottle caps, auto-
motive dashboards, pocket combs, and most other
plastic products available today. Injection molding
is the most common method of part manufacturing.
It is ideal for producing high volumes of the same
object. Some advantages of injection molding are
high production rates, repeatable high tolerances,
and the ability to use a wide range of materials, low
labour cost, minimal scrap losses, and little need to
finish parts after molding. Some disadvantages of
this process are expensive equipment investment,
potentially high running costs, and the need to de-
sign moldable parts.
Design
Molds separate into two sides at a parting line, the
A side, and the B side, to permit the part to be ex-
tracted. Plastic resin enters the mold through
a sprue in the A plate, branches out between
the two sides through channels called runners, and
enters each part cavitythrough one or more spe-
cialized gates. Inside each cavity, the resin flows
around cores and conforms to the cavity geom-
etry to form the desired part. The amount of
resin required to fill the sprue, runner and cavities
of a mold is a shot. When a core shuts offagainst
an opposing mold cavity or core, a hole results in
the part. Air in the cavities when the mold closes
escapes through very slight gaps between the
plates and pins, into shallow plenums called
vents. To permit removal of the part, its features
must not overhang one another in the direction
that the mold opens, unless parts of the mold are
designed to move from between such overhangs
when the mold opens. Sides of the part that appear
parallel with the direction of draw are typically draft
with to ease release of the part from the mold, and
examination of most plastic household objects will
reveal this. Parts with bucket-like features tend to
shrink onto the cores that form them while cool-
ing, and cling to those cores when the cavity is
pulled away. The mold is usually designed so that
the molded part reliably remains on the ejector side
of the mold when it opens, and draws the runner
and the sprue out of the side along with the parts.
The part then falls freely when ejected from the side.
Tunnel gatestunnel sharply below the parting sur-
face of the B side at the tip of each runner so that
the gate is sheared off of the part when both are
ejected. Ejector pins are the most popular method
for removing the part from the side core, but air
ejection, and stripper plates can also be used de-
pending on the application. Most ejector plates are
found on the moving half of the tool, but they can
be placed on the fixed half if spring loaded. For
thermoplastics, coolant, usually water with cor-
rosion inhibitors, circulates throughpassageways
bored through the main plates on both sides of the
mold to enable temperature control and rapid part
solidification.

MOULD EXTRACTION
A die is usually made in two halves and when closed
it forms a cavity similar to the casting desired. One
half of the die that remains stationary is known as
cover die and the other movable half is called
“ejector die”.
The die casting method is used for castings of non-
ferrous metals of comparatively Low fusion tem-
perature. This process is cheaper and quicker than
permanent or sand mould casting. Most of the au-
tomobile parts like fuel pump, carburetor bodies,
Horn heater, wipers, brackets, steering wheels,
hubs and crank cases are made with this process.
Core: The core which is the male portion of the mold
forms the internal shape of the molding.
Cavity: The cavity which is the female portion of the
mold, gives the molding its external form.

Introduction To Ansys
ANSYS is general-purpose finite element analysis
(FEA) software package. Finite Element Analysis
is a numerical method of deconstructing a complex
system into very small pieces (of user-designated
size) called elements. The software implements
equations that govern the behaviour of these ele-
ments and solves them all; creating a comprehen-
sive explanation of how the system acts as a whole.
These results then can be presented in tabulated,
or graphical forms. This type of analysis is typically
used for the design and optimization of a system far
too complex to analyze by hand. Systems that may
fit into this category are too complex due to their
geometry, scale, or governing equations.
ANSYS is the standard FEA teaching tool within
the Mechanical Engineering Department at many
colleges. ANSYS is also used in Civil and Electrical
Engineering, as well as the Physics and Chemistry
departments.

Conclusion
This project work deals with design of mold tool
and cooling channel optimization of remote control
top panel to suggest optimum material and cooling
channel system to reduce warpage of the product.
Initially literature survey and data collection was
done to understand the methodology and material
selection.
Remote control top panel was modeled and designed
mold tool for the same using parametric software
creo-2.0 (pro-engineer).
Mold flow analysis was conducted on part by vary-
ing plastic materials.
As per flow analysis P.P (polypropylene) is showing
good characteristics in confidence of fill and quality
with in low pressure and less drop, but it requires
little bit high temperature than other materials.
Thermal analysis is done in ansys work bench by
varying cooling channel systems to analyze thermal
behavior.
As per thermal analysis spiral system is showing
good quality in providing sufficient cooling effect to
the part.
As per above analysis results this project work con-
cludes that remote control with P.P (polypropylene)
material along with spiral cooling channel system
gives good quality product due to its quality of filling
and sufficient cooling effect.
