This document provides information about shell casting production technology. It discusses shell casting as a metal casting process where a resin-coated sand forms an expendable mold, allowing for higher precision and productivity than sand casting. The document outlines the shell casting process which involves pattern creation, mold creation by coating a heated pattern with sand-resin mixture, mold assembly, pouring molten metal, cooling, and casting removal. Typical applications include small to medium parts for industries like automotive and defense.

Presentation study of manufacturing process in hmt machine tools limited.docxAbu Sufyan Malik
Manufacturing is the production of products for use or sale using labour and machines, tools, chemical and biological processing, or formulation, and is the essence of secondary industry. The term may refer to a range of human activity, from handicraft to high-tech, but is most commonly applied to industrial design, in which raw materials from primary industry are transformed into finished goods on a large scale. Such finished goods may be sold to other manufacturers for the production of other more complex products or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).
Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product. The manufacturing process begins with the product design, and materials specification from which the product is made. These materials are then modified through manufacturing processes to become the required part.
The manufacturing sector is closely connected with engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Cast Parts. Examples in Europe include Volkswagen Group, Siemens, FCA and Michelin. Examples in Asia include Toyota, Yamaha, Panasonic, LG, Samsung and Tata Motors.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

My project will help to record the events coordinated by faculties with their Name, Event subject, date & details in an efficient & effective ways.
In my system we have to make a system by which a user can record all events coordinated by a particular faculty. In our proposed system some more featured are added which differs it from the existing system such as security.
Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.

3. • Shell molding, also known as shell-mould casting,
is an expendable mould casting process that uses a
resin covered sand to form the mould
•As compared to sand casting, this process has
better dimensional accuracy, a higher productivity
rate, and lower labour requirements
•It is used for small to medium parts that require
high precision.
•Shell mould casting is a metal casting process
similar to sand casting, in that molten metal is
poured into an expendable mould.

4. •Shell mould casting requires the use of a metal pattern,
oven, sand-resin mixture, dump box, and molten metal
•Shell mould casting allows the use of both ferrous and
non-ferrous metals, most commonly using cast iron,
carbon steel, alloy steel, stainless steel, aluminium
alloys, and copper alloys

•Typical parts are small-to-medium in size and
require high accuracy, such as gear housings,
cylinder heads, connecting rods, and lever arms
6. •A two-piece metal pattern is created in the shape of
the desired part, typically from iron or steel.
PATTERN CREATION
•A two piece metal pattern is created in the shape of the
the desired part typically from iron and steel.
•Other materials are sometimes used such as aluminum
for low volume production or graphite for casting
reactive material.
7. First, each pattern half is heated to 175°C - 370°C and
coated with a lubricant to facilitate removal.
Next, the heated pattern is clamped to a dump box
which contains a mixture of sand and resin binder.
The dump box inverted allowing this sand-resin
mixture to coat the pattern.
The heated pattern partially cures the mixture which
now forms a shell around the patterns.
Each pattern half and surrounding shell is cured to
completion in an oven and then the shell halves are
joined together.
Mould Creation
8. The two shell halves are joined and securely clamped to
form the complete shell mould
If any cores are required, they are inserted prior to closing
the mould
The shell mould is then placed into a flask and supported
by a backing material
MOULD ASSEMBLY
9. The mould is securely clamped together while the
molten metal is poured from a ladle into the gating
system and fills the mould cavity.
POURING
10. After the mould has been filled, the molten metal is
allowed to cool and solidify into the shape of the
final casting.
COOLING
11. •After the molten metal has cooled, the mould can be
broken and the casting removed.
• Trimming and cleaning processes are
required to remove any excess metal from the feed system
and any sand from the mould.
