注塑制品脱模顺利与否主要取决于成型模具结构的合理设计和注塑制品工艺参数的合理选择。在注射成型生产中，由于工艺条件的波动，有时也会出现制品脱模困难的现象。

The smooth ejection of injection molded products mainly depends on the reasonable design of the molding structure and the reasonable selection of the technological parameters of the injection molding products. In the process of injection molding, because of the fluctuation of technological conditions, sometimes it is difficult to remove products.

为了保证制品注射成型的生产顺利进行，避免因制品脱模困难而造成制品生产周期延长，成型模具的型腔表面要喷涂或擦涂一层脱模剂。

In order to ensure the production of injection molding products successfully carried out, to avoid product stripping difficult to produce product cycle extended, mold mold cavity surface should be sprayed or coated with a release agent.

脱模剂的选择应根据注射制品用原料决定。应用较多的一种脱模剂是硬脂酸锌，除了聚酰胺树脂；还有硅油类脱模剂，其脱模效果好，但价格较贵。

The selection of release agents shall be based on the raw material used in the injection. A more applied release agent is stearic acid zinc, in addition to polyamide resin, there are silicone oil release agent, its release effect is good, but the price is more expensive.
