Engineering polymers (Engineering Plastics) are a group of plastic materials that have improved mechanical and thermal properties that make them ideal for all types of engineering applications, replacing traditional materials equal or greater in weight, hardness or other properties, while being much simpler to manufacture, especially with complex shapes. At Raj engineering works we make feed screw & barrel set for the following types of polymers.
Acrylonitrile butadiene styrene ABS
Polyamides (PA) compounds
Polybutylene terephthalate PBT
Polyethylene terephthalate PET
Polyoxymethylene plastic POM / Acetal
POM C and POM H
Polyphenylene sulfide PPS
Polyphenylene oxide PPO
Polytetrafluoroethylene PTFE / Teflon
Poly(methyl methacrylate) PMMA
Engineering polymers blends:
A polymer mixture (“alloy”) is the combination of two or more polymers that fuse to create a new material with different physical properties. Polymer blends are an effective method of developing new polymer-based materials for a wide range of applications. The key to their proper use is to adjust the properties of the new material by appropriate selection of the component polymers
1. Nitrided Standard and Advanced
2. Bimetallic Standard and Advanced
3. Cermet Standard and Advanced
Diameter 22 mm to 250 mm, barrel 450 mm
Length: 600 mm to 12000 mm, barrel 11000 mm
These plastics are processed by injection molding, extrusion, roto molding and blow molding techniques.
We also offers Bimetallic screw barrel set for High-performance plastics
High performance plastics differ from standard plastics and engineering plastics primarily by their temperature stability, but also by their chemical resistance and mechanical properties, production quantity, and price.
There are many synonyms for the term high-performance plastics, such as: high temperature plastics, high-performance polymers, high performance thermoplastics or high-tech plastics. The name high temperature plastics is in use due to their continuous service temperature (CST), which is always higher than 150 °C by definition.
Among the high-performance polymers, fluoropolymers have 45% market share (main representatives: PTFE), sulfur- containing aromatic polymers 20% market share (mainly PPS), aromatic polyarylether and Polyketones 10% market share (mainly PEEK) and liquid crystal polymers (LCP) 6%. The two largest consumers of high-performance plastics are the electrical and electronics industries (41%) and the automotive industry (24%). All remaining industries (including chemical industry) have a share of 23%.
