塑化挤出：
原料在挤出机内，受到螺杆的剪切 EPDM隔音片材设备_EPDM隔音片材设备_佳德、挤压和加热作用，逐渐融化并形成均匀的熔体。挤出机的温度、螺杆转速和压力等参数需要精确控制，以保证良好的塑化效果。
The process of the POE interior sheet EPDM隔音片材设备_EPDM隔音片材设备_佳德 production line and the EVA interior sound insulation sheet extruder usually includes the following main steps:
Raw material preparation:
POE or EVA granular raw EPDM隔音片材设备_EPDM隔音片材设备_佳德materials undergo strict screening and quality inspection to ensure their purity and performance meet production requirements. At the same time, various additives such as plasticizers, stabilizers, and flame retardants may be added to improve the performance of the sheets.
Extrusion process:
The raw materials are sent to the hopper of the extruder and gradually melt and mix evenly through the rotation and heating of the screw. Parameters such as temperature, pressure, and screw speed in the extruder need to be precisely controlled to EPDM隔音片材设备_EPDM隔音片材设备_佳德 ensure the plasticizing effect and extrusion stability of the materials.
Mold forming:
The molten materials are extruded through a mold of a specific shape to form the required sheet shape and size. The design and manufacturing accuracy of the mold have an important influence on the quality and dimensional accuracy of the sheets.
Cooling and setting:
The extruded sheets pass EPDM隔音片材设备_EPDM隔音片材设备_佳德through the cooling device and are rapidly cooled and solidified to maintain their shape and size. Common cooling methods include water cooling or air cooling.
