在设置注塑工艺参数时，一般遵循以下流程，每一步都总结了其设置的要点。下面有几点要理解。
When setting injection molding process parameters, the following process is generally followed, and the key points of setting are summarized in each step. Here are a few points to understand.
设定塑料的塑化温度
Set the plasticizing temperature of the plastic
(1)温度过低时，塑料可能未完全熔化或难以流动。
(1) When the temperature is too low, the plastic may not melt completely or it may be difficult to flow.
(2)如果熔化温度过高，塑料会解释。
(2) If the melting temperature is too high, the plastic will explain.
(3)从塑料供应商处获得准确的熔化温度和成型温度。
(3) Obtain accurate melting and forming temperatures from the plastic supplier.
(4)机筒上有三至五个加热区。靠近料斗的加热区温度较低，然后逐渐升高温度。喷嘴处的加热器需要保证温度的一致性。
(4) There are three to five heating zones on the barrel. The temperature in the heating zone near the hopper is low, and then gradually increases. The heater at the nozzle needs to ensure the consistency of temperature.
(5)实际熔化温度通常高于加热器的设定值，主要是由于背压和螺杆旋转产生的摩擦热的影响。
(5) The actual melting temperature is usually higher than the set value of the heater, mainly due to the influence of back pressure and friction heat caused by screw rotation.
(6)探针温度计可以测量溶液的实际温度。
(6) The probe thermometer can measure the actual temperature of the solution.
设置模具温度
Set mold temperature
(1)从塑料供应商处获得模具温度的推荐值。
(1) Obtain the recommended mold temperature from the plastic supplier.
(2)模具温度可用温度计测量
(2) Mold temperature can be measured by thermometer
(3)冷却液的温度应设置为比模具温度低10-20°。
(3) The temperature of the coolant should be set 10-20 ° lower than the mold temperature.
(4)如果模具温度在40-50°或更高，需要考虑在济南模具加工和模板之间设置保温板。
(4) If the mold temperature is 40-50 ° or higher, it is necessary to consider setting insulation board between mold processing and formwork in Jinan.
(5)为了提高零件的表面质量，有时还需要较高的模具温度。
(5) In order to improve the surface quality of parts, sometimes higher mold temperature is required.
设置螺杆的注射焦点
Set the injection focus of the screw
(1)注射终点是从充填阶段切换到保压阶段时螺杆的位置。
(1) The injection end point is the position of the screw when switching from the filling stage to the pressure maintaining stage.
(2)如果垫料不足，产品表面可能会出现凹痕。一般情况下垫料的长度设置为5-10mm。
(2) If the padding is insufficient, dents may appear on the product surface. Generally, the length of padding is set as 5-10mm.
(3)
济南注塑模具厂家经验表明，如果在本步骤中将注射点设置为填充型腔的2/3，可以防止注塑机和注塑模具的损坏。
(3) Jinan injection mold manufacturer's experience shows that if the injection point is set to 2/3 of the filling cavity in this step, the damage of the injection machine and injection mold can be prevented.
Here are three key points for setting process parameters during injection molding. You can refer to them. Of course, if you have other questions, please follow us at www.sdlqmj Www. 68mn!
