The extrusion molding process of plastic pipe is divided into three stages I. Plasticization of raw materials. This process can make the solid materials turn into a uniform viscous fluid through the heating and mixing of the extruder; II. Forming. Under the function of extrusion parts of the extru......
Read MoreIn the production process, since PVC is a kind of heat sensitive material, even if heat stabilizer is added, it can only increase the decomposition temperature and prolong the stable time without decomposition, which requires strict control of PVC molding temperature. Especially for RPVC, since its ......
Read MoreAs a common extruder equipment, the single screw extruder is used in plastic processing industry. What is its principle and structure? Below is the analysis for the single screw extruder from the extruder conveying section, compression section and metering section. The effective length of single ......
Read MoreScrew is one of the core parts of the plastic extruder equipment. When we use extruder normally, the life of screw can sometimes restrict the service life of the equipment. So we need to know how to improve the life of the screw in the extruder. Ningbo Fangli Technology Co., Ltd. is a mechanical eq......
Read MoreThe extruder production line can continuously produce plastic pipes. Because the pipe production is uninterrupted, and the pipe has a fixed length specified in the standard, in order to ensure the standard length of the pipe, we need to use the cutting machine as an auxiliary equipment to cut the pi......
