WebApr 29, 2024 · The plastic injection molding process is commonly used when large amounts of parts are needed quickly, when piece prices need to remain low, and when all parts need to be identical in size and other metrics. The main benefit of this process is its cost effectiveness; sometimes it costs just cents per part for parts at scale. WebPlastics Extrusion. Plastics extrusion is a normally high volume manufacturing process where a polymer material, enriched with the desired additives, is melted and formed in a continuous process. The raw material (polymer) in the form of granulates, is gravity fed into the hopper and through the feed throat, drops on a rotating screw. fleece jacket down vest combo
