Principle of wire extruder machine: Plastic extrusion equipment is widely used for processing pipes, rods, monofilaments, plates, films, wire and cable coatings, and similar profiles.


The working principle of the cable extrusion machine is to melt and plasticize the solid plastic under the premise of heating and the screw of the extruder to twist and reduce pressure. After a specially designated shape of the mouth mold, the cross section and the shape of the mouth mold-sample area-even plastic products are formed. . The editor of the micro-extruder will introduce that the main materials are carbon layout steel, gold-opening objects, etc. Some extrusion dies will also be inlaid with wear-resistant materials such as diamond on the parts that require wear-resistant. Extrusion process-generally only used for the production of thermoplastic products, its structure is clearly distinguished from injection molds and compression molds.


Foaming and extrusion: Thermoplastic elastomer tpv can be foamed through chemical and mechanical methods. For chemical foaming, foam reducing agents such as bihydrochloride can be used. The achievable foam density specific gravity ranges from 0.97 (typically foamed tpv) to 0.70. Low ground density is disturbed by patents. The foam collector will degenerate at 180°C to 190°C, because most of the tpv base is implemented under the premise of 195 to 215°C.


Multi-extrusion: Co-extrusion is the technique of combining two materials into one part in one extrusion process. The two extruders are connected in series to supply the bottom mold and make the respective polymer materials co-extruded along the corresponding channels-the same, so as to obtain the extruded glue of the two materials. Homogeneous geological materials, such as tpv and disperse propylene, can all be fused together. Multi-layer extrusion is a good way to confuse hard and hard materials. A more typical example is that the high-hardness section, such as thermoplastic elastomer tpv, is usually used as a component support layout, and low-hardness geological materials provide flexibility. This is common in sealed applications. Because the sealed area is hard, the soft geological material can be squashed to obtain a good sealing result. In the process of equilibrium flow field, it is simpler to use thermoplastic elastomer tpv with higher hardness as a rigid material to replace disperse propylene.

Welding joints: thermal welding is more fluid and can be used to apply tpv to squeeze out the glue. The heat is bowed into the adjacent area to melt the appearance, and then the appearance is put together, and the heavy burden is reduced to ensure that no gas enters the fighting area. However, after the heat, the strength of the part and the part itself are almost the same. Another way to connect the extruded parts is to use an adhesive system.
