machine is widely used in the processing of pipes, rods, monofilaments, plates, films, wire and cable coatings, profiles and so on. The principle of the plastic extruder machine is that the solid plastic is melted and plasticized under the conditions of heating and screw rotation of the extruder, and a continuous plastic product having the same cross-section and shape as the die is formed by a die of a specific shape. The manufacturing materials mainly include carbon structural steel, alloy tools, etc. Some extrusion dies are also embedded with wear-resistant materials such as diamond on parts that require wear resistance. Extrusion process is usually only applicable to the production of thermoplastic products, which are structurally distinct from injection molds and compression molds. Principle of Plastic Extrusion Machine: Foam extrusion: The thermoplastic elastomer tpv can be foamed by chemical and mechanical methods. For chemical foaming, a blowing agent such as a heavy hydrochloride salt can be used. The foam density specific gravity that can be achieved is 0.97 (typically unfoamed tpv) to 0.70. Lower density is affected by patents. The blowing agent degrades at 180 \u00b0 C to 190 \u00b0 C because most of the tpv is based on&#8230;
