保定塑料机械设备厂

塑料机械一般分为两种，一种是注塑机，另一种是挤出机。

Plastic machinery is generally divided into two kinds, one is an injection molding machine, and the other is an extruder.

挤出机是在螺杆作用下将熔融塑料通过固定形状的挤出口挤出，在牵引机作用下经水冷定型后切割．主要用于各种相同截面产品的大量持续生产，如管＼棒＼异型材等，也可用于塑料改性造粒．

In the screw extruder is under the action of the molten plastic extrusion through fixed shape extrusion, water cooling after cutting in the traction machine under the same section is mainly used for a variety of products. A large number of continuous production, such as tube, rod, profile, also can be used for plastic modification and granulation.

注塑机是将熔融塑料注射进模具，冷却后即为产品．用途非常广泛，根据塑料不同，使用的地方也不同．

Injection molding machine is the injection of molten plastic into the mold, cooling is the product. The use is very extensive, according to different plastics, the use of different places
