[0002] Internal mixer is an important industrial equipment specially used for efficient mixing and processing of various materials, especially rubber and plastic. This machine mixes raw materials evenly through physical force to produce a homogeneous final product with specific properties. Traditional internal mixer design uses mechanical or hydraulic systems to apply pressure to ensure that the materials are fully mixed under high temperature and pressure. In these systems, the push pin on the hydraulic press is a key component. Its function is to keep the push rod or piston in the correct position to maintain constant pressure and process the material.
