Liner In Extrusion Barrel Of Extrusion Press Machine

The extrusion cylinder is an important large-scale tool for extrusion production. It is a multi-layer structure, which is difficult to process and expensive. The lining of the extrusion cylinder is the main wearing part of the extrusion machine, and it is also one of the important tools that affects the quality of the product. The inner diameter of the lining of the extrusion cylinder is the basis for determining the working diameter of the die support and the extrusion pad. When the diameter difference between the working part and the non-working part of the lining is > 0.4mm or the longitudinal groove is > 5mm, or the surface of the extruded product has peeling and air bubbles, the lining should be replaced.
