在設置注塑工藝參數時，一般遵循以下流程，每一步都總結了其設置的要點。下面有幾點要理解。
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.
設定塑料的塑化溫度
Set the plasticizing temperature of the plastic
(1)溫度過低時，塑料可能未完全熔化或難以流動。
(1) When the temperature is too low, the plastic may not melt completely or it may be difficult to flow.
(2)如果熔化溫度過高，塑料會解釋。
(2) If the melting temperature is too high, the plastic will explain.
(3)從塑料供應商處獲得準確的熔化溫度和成型溫度。
(3) Obtain accurate melting and forming temperatures from the plastic supplier.
(4)機筒上有三至五個加熱區。靠近料斗的加熱區溫度較低，然后逐漸升高溫度。噴嘴處的加熱器需要保證溫度的一致性。
(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)實際熔化溫度通常高于加熱器的設定值，主要是由于背壓和螺桿旋轉產生的摩擦熱的影響。
(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)探針溫度計可以測量溶液的實際溫度。
(6) The probe thermometer can measure the actual temperature of the solution.
設置模具溫度
Set mold temperature
(1)從塑料供應商處獲得模具溫度的推薦值。
(1) Obtain the recommended mold temperature from the plastic supplier.
(2)模具溫度可用溫度計測量
(2) Mold temperature can be measured by thermometer
(3)冷卻液的溫度應設置為比模具溫度低10-20°。
(3) The temperature of the coolant should be set 10-20 ° lower than the mold temperature.
(4)如果模具溫度在40-50°或更高，需要考慮在濟南模具加工和模板之間設置保溫板。
(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)為了提高零件的表面質量，有時還需要較高的模具溫度。
(5) In order to improve the surface quality of parts, sometimes higher mold temperature is required.
設置螺桿的注射焦點
Set the injection focus of the screw
(1)注射終點是從充填階段切換到保壓階段時螺桿的位置。
(1) The injection end point is the position of the screw when switching from the filling stage to the pressure maintaining stage.
(2)如果墊料不足，產品表面可能會出現凹痕。一般情況下墊料的長度設置為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)
濟南注塑模具廠家經驗表明，如果在本步驟中將注射點設置為填充型腔的2/3，可以防止注塑機和注塑模具的損壞。
(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!
