塑料作为一种高分子的化合物有各种各样的处理方法方法。每种方法都有其优点和缺点，更适合于特定的应用。接下来我们通过相关有趣的动图看看他们是如何被加工的！

@There are a variety of methods used to process plastic. Each method has its advantages and disadvantages and are better suited for specific applications. There are various plastic processing techniques featured with their relevant animations.

注塑机

Injection Molding

注塑是一种通过将材料注射到模具中制造零件的制造方法。加工塑料的主要方法是注射成型。在这个过程中，塑料被放置到料斗，然后料斗将塑料加热注入，它是通过一长的腔室与一个往复螺杆推压。之后，它被软化成流体状态。喷嘴位于腔室的末端，流体塑料通过喷嘴强制冷却，闭合模具。当塑料冷却和固化时，半成品从压机中退出。

@Injection molding is a manufacturing process for producing parts by injecting material into a mold. The main method used for processing plastic is injection molding. With this process, the plastic is placed into a hopper. The hopper then feeds the plastic into a heated injection unit, where it is pushed through a long chamber with a reciprocating screw. Here, it is softened to a fluid state. A nozzle is located at the end of the chamber. The fluid plastic is forced through the nozzle into a cold, closed mold. The halves of the mold are held shut with a system of clamps. When the plastic is cooled and solidified, the halves open and the finished product is ejected from the press.

塑料挤出

Plastic Extrusion

塑料挤压是一个大批量制造的方法，其中塑料原材料被熔化形成连续的轮廓。挤出的过程通常是用来制造如膜，连续片材，管，型材，棒材，外套丝，长丝，线，和电缆。和注塑机一起，干燥的塑料放置到料斗并送入一个长的加热室中。在腔室的末端，材料被压出一个小开口，或在所需的最终产品的形状的模具。塑料离开模具后，它被放置在传送带上冷却。鼓风机有时会在此过程被使用，帮助其冷却。

@Plastics extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile. The process of extrusion is usually used to make products such as film, continuous sheeting, tubes, profile shapes, rods, coat wire, filaments, cords, and cables. As with injection molding, dry plastic material is placed into a hopper and fed into a long heating chamber. At the end....
