注塑成型（Injection Molding）
受热融化的材料由高压射入模腔，经冷却固化后，得到成形品的方法。该方法适用于形状复杂部件的批量生产，是重要的加工方法之一。
注射成型过程大致可分为以下6个阶段 ：
合模、注射、保压、冷却、开模、制品取出
上述工艺反复进行，就可连续生产出制品。
现今加工工艺的趋势正朝着高新技术的方向发展，这些技术包括：微型注塑、高填充复合注塑、水辅注塑、混合使用各种特别注塑成型工艺、泡沫注塑、模具技术、仿真技术等。

The heating melts material by high-pressured injection cavity, after cooling solidification, obtains the forming method. This method is suitable for the shape complex part's volume production, is one of important processing methods.
The injection molding process may divide into the following 6 stages approximately:
The matched molds, the injection, guarantee the pressure, cooling, the die sinking, the product to take out
The above craft carries on repeatedly, may the continuous production product.
Nowadays processes the craft the tendency to develop toward the high technology and new technology direction, these technologies include: The miniature injection molding, the high packing compound injection molding, the water auxiliary injection molding, the mix use each kind of specially injection molding craft, the froth injection molding, the mold technology, the emulation technique and so on.
