塑料都有一个建议的熔化温度和固化温度范围，因而需要将热流道与流道和喷嘴间进行**的热隔离。 济南注塑加工 http://www.sdlqmj.com/
The plastic has a recommended melting temperature and curing temperature range, so it is necessary to heat the flow path and the nozzle and the effective thermal isolation between the nozzle.
为了使用自然平衡的流道，**设计喷嘴。这是确保均衡的压力损失和熔体在所有的模腔中有一样的停留时间的**方法。
In order to use the natural balance of the flow, the best design nozzle. This is the only way to ensure that the equilibrium pressure loss and melt have the same residence time in all the cavities.
对小注射量的注射产品，间接浇口比直接浇口更适宜，玻璃纤维增强塑料材料更是如此。材料通过喷嘴的量逐渐增加，因而产生在聚合物的热量更易控制。用于热流道喷嘴的浇口可以很大，而使用传统方法加工的部件的浇口较小。冷料穴不管如何都应设置在面对热流道的位置，这是阻止冷料通过喷嘴进入成型部件的**方法。
Indirect injection gate is more suitable for small injection products than direct gate. The amount of material passing through the nozzle increases gradually, resulting in a greater control of the heat in the polymer. The gate for the hot runner nozzle can be very large, and the gate of the component that is processed by the conventional method is smaller. No matter how cold the material should be placed in the face of the hot runner position, which is the only way to prevent cold material through the nozzle into the molding parts.
热流道的入口、流道和每个喷嘴应当分别控制，使各个部件对热敏感性的混合物分别作出平衡。应使用调节设备以保证在适应能源供应的过程中保持温度恒定（如PID）。
The inlet, the flow passage, and each nozzle of the hot runner should be controlled separately, so that each component can balance the heat sensitive mixture. Should be used to ensure that the adjustment device in the process of energy supply to maintain a constant temperature (such as PID).
热流道系统应使用与顶出系统同样的方法来进行机械支持。模具在接近流道的位置处比较薄弱，必须尽可能地进行补偿。在接近热流道喷嘴处使用单独的加热回路，可使模具表面温度达到正确的设定值。
Hot runner systems should be used in the same way as the ejector system for mechanical support. The mold is close to the flow channel position is weak, must compensate as far as possible. In the vicinity of the hot runner nozzle using a separate heating circuit, so that the mold surface temperature to achieve the correct set value.
