TPE products (such as pipes, wires, sealing strips and other TPE material products) in the extrusion production process often have the following problems:

　　1、Rough surface of molded products

　　Generally due to poor plasticization, caused by the surface roughness of the finished product.

　　First, increase the temperature and adjust the screw speed, replace the screen (fine mesh)

　　Secondly, select the appropriate thermoplastic elastomer TPE and dry, some materials are not dry for molding, there will be foaming, surface roughness of such problems.

　　2, scaling

　　Fouling is extrusion molding deposits accumulated in the edge of the mouth type, its composition is from the extrusion molding materials, but also from special additives.

　　First, reduce the amount of lubricant to effectively improve the characteristics of the material.

　　Secondly, the use of Teflon coating method can also reduce the generation of scaling.
