Plastics International News and Blog

Compression molding is a common process used for both thermoplastic and thermoset stock shape materials. Compression molding is accomplished by placing the plastic material (can be a granular or pelletized form) in a mold cavity to be formed by heat and pressure.

How To Minimize Cycle Time In Injection Molding

2018/2/6Injection molding cycle time is likely to be one of the biggest factors in the efficiency of your process — both from a time and a cost standpoint. Of course, since time is money in any manufacturing process, what this really means is that looking into ways of reducing cycle time in your injection molding process can have a major impact on your bottom line.

Polyphenylene sulfide Reinforced with 40% Glass Fibre

Reinforced engineering polymer (Polyphenylene sulfide) with 40% glass fiber. Its key features include: Service temperatures up to 240 C Very good resistance to chemicals and solvents Inherent flame resistant (UL 94 V-0, some grades 5VA) Very low moisture

International Polymer Processing Volume 32 Issue 2

In this study, a mold is designed for fabricating a Fresnel flash lens involving injection compression molding (ICM). The Taguchi method and parametric analysis are applied to examine the effect of process parameters (mold temperature, melt temperature, injection speed, packing pressure, compression pressure, and time) on the molding quality.

Methods for continuous processing

The molding billet process for making PTFE filled sheets has proven to be impractical for many reasons. The molding and sintering steps must be performed within the confines of the billet mold under high pressure (5 to 10,000 plus, PSI). A quality filled

2020/5/16Instead, similar to metal powder forming, the granular resins are processed by compression molding at ambient temperature followed by sintering above the crystalline melting point. Various copolymers of tetrafluoroethylene (PFA, FEP, ETFE) and other fluoropolymers with lower melting point and crystallinity were developed to overcome the lack of melt processability of PTFE.

Plastic Resin Families and Applications

The first commercial grades of polyphenylene sulfides (PPS) were introduced by Phillips Petroleum in 1968 under the trade name Ryton. These were of two types, a thermoplastic branched polymer of very high viscosity which was processed by PTFE-type processes, and an initially linear polymer which could be compression molded.
