谈谈挤出成型工艺中的加热与冷却王胜杰塑料成型工艺很多。常见的有挤出、注射、浇铸、层压、发泡、压延、涂复等。挤出成型工艺在塑料制品生产中应用最广。在挤出工艺控制的诸多因素中，物料温度无疑具有相当重要的地位。在温度控制中，物料加热是一个方面，物料冷却是另... Talk about extrusion molding process of heating and cooling Wang Shengjie many plastic molding process. Common extrusion, injection, casting, lamination, foaming, rolling, Tu Fu and so on. Extrusion molding process in the production of plastic products the most widely used. In the extrusion process control of many factors, the material temperature undoubtedly has a very important position. In temperature control, material heating is one aspect, material cooling is another ...
