“Applications Of Powder Metallurgy In Reference with Cutting tools”Dushyant Kalchuri
Powder metallurgy is used for manufacturing products or articles from powdered metals by placing these powders in molds and are compacting the same using heavy compressive force. Typical examples of such article or products are grinding wheels, filament wire, magnets, welding rods, tungsten carbide cutting tools, self-lubricating bearings electrical contacts and turbines blades having high temperature strength. The manufacture of parts by powder metallurgy process involves the manufacture of powders, blending, compacting, profiteering, sintering and a number of secondary operations such as sizing, coining, machining, impregnation, infiltration, plating, and heat treatment.
The powder metallurgy is a process of formation of metal powder. With the help of different processes. Some of the processes are described in the presentation.
In sand casting, sand is used to define the cavity inside a mold. In addition, sand is used to make any cores that are contained in the mold. The molten metal solidifies in the cavity between the interior of the mold and the exterior of the core.
Reasonable product design and mold design are key technologies that affect the success of injection molding. This article introduces some basic principles of injection molded product design and mold design.
1. The basic conditions of plastic product design

thGAP - BAbyss in Moderno!! Transgenic Human Germline Alternatives ProjectMarc Dusseiller Dusjagr
thGAP - Transgenic Human Germline Alternatives Project, presents an evening of input lectures, discussions and a performative workshop on artistic interventions for future scenarios of human genetic and inheritable modifications.
To begin our lecturers, Marc Dusseiller aka "dusjagr" and Rodrigo Martin Iglesias, will give an overview of their transdisciplinary practices, including the history of hackteria, a global network for sharing knowledge to involve artists in hands-on and Do-It-With-Others (DIWO) working with the lifesciences, and reflections on future scenarios from the 8-bit computer games of the 80ies to current real-world endeavous of genetically modifiying the human species.
We will then follow up with discussions and hands-on experiments on working with embryos, ovums, gametes, genetic materials from code to slime, in a creative and playful workshop setup, where all paticipant can collaborate on artistic interventions into the germline of a post-human future.

1. Post-vulcanization treatment of rubber products
After the vulcanization is completed, the rubber products often need some
post-treatment to become a qualified finished product. This includes: 1 the trimming of
the rubber mold products, so that the surface of the product is smooth and the outer
dimensions meet the requirements; 2 after some special processing, such as
processing the surface of the product, the performance of the special-purpose products
is improved; Articles containing fabric skeletons such as tapes, tires, etc. are subjected
to hot stretching cooling and vulcanization and then cooled under inflation pressure to
ensure product size, shape stability and good performance.
1. Trimming of mold products after vulcanization
When the rubber mold product is vulcanized, the rubber material will continue to flow
2. out along the parting surface of the mold to form an overflow rubber edge, also known
as a flash or flash edge. The thickness and thickness of the rubber edge are
determined by the structure and precision of the mold. The parallelism of the flat
vulcanizer plate and the amount of glue remaining. Nowadays, the products produced
by the infinite mold have a very thin rubber edge, and sometimes they can be removed
or gently rubbed off when the mold is released. However, such molds are expensive
and fragile, and most rubber moldings require finishing after curing.
Manual finishing
Manual trimming is an ancient method of trimming, which involves manually punching
the edges with a punch; removing the edges with scissors, scraping, etc. The quality
and speed of hand-trimmed rubber products will vary from person to person and
require trimming
The geometry of the finished product must conform to the product drawing
requirements and must not be scratched, scratched or deformed. Before trimming, it is
necessary to clearly understand the trimming parts and technical requirements, master
the correct dressing method and use the tools correctly.
2. Mechanical dressing
Mechanical finishing refers to the process of trimming & 5 of rubber mold products
using various special machines and corresponding process methods. It is currently a
more advanced method of dressing.
(1) Mechanical punching and trimming The rubber edge of the product is removed by
means of a press machine and a die and a punching knife. This method is suitable for
articles and molded articles whose glue edges can be placed on the die or the
punching plate, such as stoppers, cups, and the like. For products with high gel content
and low hardness, the impact method is generally used to impact the trimming edge. In
this way, the edge of the knife can be reduced due to the large elasticity of the product,
and the side surface is concave; and the rubber content is lower and the hardness is
higher. The product can be directly cut by the knife die method. In addition, die cutting
is also divided into cold cutting and hot cutting. Cold cutting refers to punching at room
temperature, requiring higher punching pressure and better punching quality. Hot
cutting refers to higher temperature -f, When punching, it should prevent the high
temperature from contacting the product for too long and affect the product quality.
(2) Mechanical cutting and trimming is suitable for the trimming of larger-sized products,
using cutting tools. A side cutting machine is a special machine, and different products
use different cutters. For example, after the tire is vulcanized, there are strips of
different lengths on the surface of the gas eye and the vent line, and the strip must be
removed using the grooved tool under the condition of the tire rotating.
(3) Mechanical grinding and trimming For mold rubber products with inner and outer
rings, grinding is usually used. The grinding blade is a grinding wheel with a certain
thickness of the particles. The precision of grinding and trimming is low, and the
3. grinding surface is rough. It may have residual sand particles, which may affect the use
effect.
(4) Low temperature shot blasting For fine products with high trimming quality
requirements, such as 0-rings, small cups, etc., this method can be used for trimming.
The product is rapidly cooled to below the brittle temperature with liquid nitrogen or dry
ice, and then the metal bullet or plastic projectile is sprayed at a high speed to break
the flash and peel off, and the trimming is completed.
(5) Low-temperature brushing and trimming It removes the rubber edge of the frozen
rubber product by means of two nylon brushes rotating around a horizontal axis.
(6) Low temperature drum trimming It is the earliest adopting the method of freezing
trimming. The impact force generated by the rotation of the drum and the friction
between the products are used to break and fall off the edge of the product that has
been frozen to below the embrittlement temperature. The shape of the drum is
generally octagonal to increase the impact force of the product in the drum, the rotation
speed of the drum should be moderate, and the addition of the abrasive can improve
the efficiency. For example, the trimming process of the rubber plug of the electrolytic
capacitor is to use a low temperature drum to trim.
(7) Low-temperature vibration trimming, also known as vibration freezing trimming, the
product is spirally vibrated in a ring-shaped sealed box, and there is a strong impact
between the products and between the product and the abrasive, causing the frozen
embrittlement drop. The low-temperature vibration trimming is better than the
low-temperature drum trimming, the product damage rate is low, and the production
efficiency is relatively low.
(8) Low-temperature swinging and dither trimming are suitable for small or
micro-products or micro-rubber products containing metal skeletons. Together with the
abrasive, the edges of the product, the corners, and the edges of the grooves are
removed.
