挤出设备/Extrusion Molding Series Equipment

挤出机是一种用于化纤、塑料、橡胶、食品等材料加工的设备，它通过将材料加热并压入模具中，使其成形为所需的形状。挤出机通常由进料系统、加热系统、挤出头、模具和冷却系统等组成，在挤出过程中，材料被加热至熔化状态，然后通过挤出头挤出成形，最后在冷却系统中冷却固化，过程中的熔体压力温度的测量控制至关重要。

Extruders are processing equipment for chemical fiber, plastics, rubber, food and other materials. Materials are heated and forced through dies to form target profiles. A typical extruder consists of feeding system, heating system, extrusion head, die and cooling system.
