塑胶射出成型工艺流程英文
英文回答：
Plastic Injection Molding Process Flow.
Plastic injection molding is a high-volume
manufacturing process for producing plastic parts. It
involves injecting molten plastic into a mold, where it
cools and solidifies into the final product. The process
flow of plastic injection molding can be summarized as
follows:
1. Material Preparation: The first step in plastic
injection molding is to prepare the raw material, which is
typically in the form of pellets or granules. The material
is heated to a molten state, usually using a screw extruder.
2. Molding: The molten plastic is then injected into a
mold, which is typically made of metal. The mold has a
cavity that is shaped according to the desired final product. The plastic fills the cavity and is held under
pressure until it cools and solidifies.
3. Cooling: Once the plastic has solidified, the mold
is opened and the part is ejected. The part is then allowed
to cool further before being handled.
4. Finishing: The final step in the plastic injection
molding process is finishing, which may involve various
operations such as trimming, decorating, and assembly.

塑料注塑成型工艺流程。
塑料注塑成型是一种用于生产塑料部件的大批量制造工艺。 它涉及将熔融塑料注入模具，在那里冷却并固化为最终产品。 塑料注塑成型的工艺流程可总结如下：
1. 材料准备，塑料注塑成型的第一步是准备原材料，通常是颗粒或粒料的形式。 该材料被加热到熔融状态，通常使用螺杆挤出机。
2. 成型，然后将熔融塑料注入模具中，模具通常是用金属制成的。 模具具有根据所需的最终产品成型的腔。 塑料填充腔体并在压力下保持，直至其冷却并固化。
3. 冷却， 一旦塑料固化，模具打开并将零件弹出。 然后让零件进一步冷却，然后再进行处理。
4. 精加工， 塑料注塑成型的最后一步是精加工，可能涉及各种操作，例如修整、装饰和组装。
