Vietnamese 要了解的 定义生产过程中的注射的模具一个人必须首先认识到普遍采用的自动化机械各行各业，包括制造塑料产品。 今天，壳体的共同的家用电器和数字产品通常产生的，通过使用注射成型模具和注射塑机。
- 加热和预塑 Driven by the transmission system, the screw continuously transports and compresses the material from the hopper. The material gradually melts under the combined action of the heater outside the barrel and the shear and friction between the screw and the barrel. When the molten plastic reaches the front of the barrel, a certain amount of molten plastic accumulates. Under the pressure of the melt, the screw slowly retracts. The retraction distance is adjusted based on the metering device’s set injection volume, after which the screw stops rotating and retracting.
- 模和锁定 模机构关闭锁和半模的—一个在运动模板和其他有关的固定模板提供足够的夹力，以确保该模保持安全，在成形的过程。
- 注射单位向前移动 After the mold is clamped, the injection unit is pushed forward, aligning the injection machine’s nozzle tightly with the mold’s main sprue.
- 注入和保持压力 一旦模是锁着的嘴是完全一致的模，注射液压缸进入高压状态，推动螺旋向前注入熔化的塑料成本模腔有足够的压力。 作为塑料冷却，它收缩，因此保持一定的压力在腔是必要的，以确保密，维的准确性和机械性质的成部分。
- 压力缓解
Once the molten plastic at the mold’s gate cools and solidifies, pressure relief can take place. - 回缩的注射部
压力之后的救济、螺钉通常转动和收回来准备下一轮料和预塑. 重要的是要注意到，在某些情况下，例如当使用PA材料、注射单位可以收回，以防止流口水在成型。 - 模开喷射塑料部件
之后的塑料部分的内部模腔冷却和凝固，该模的机构打开了模，而部分是从喷模。 在这一点上，一个完整的塑料产品的生产。
大多数塑料部件，在生产之后，通常接受额外的进程，例如绘画、屏幕印刷、烫金，或激光雕刻。 最终产品，然后与其它部件组装之前被传递给消费者。
