在設(shè)置注塑工藝參數(shù)時(shí)，一般遵循以下流程，每一步都總結(jié)了其設(shè)置的要點(diǎn)。下面有幾點(diǎn)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(shè)定塑料的塑化溫度
Set the plasticizing temperature of the plastic
(1)溫度過(guò)低時(shí)，塑料可能未完全熔化或難以流動(dòng)。
(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(guò)高，塑料會(huì)解釋。
(2) If the melting temperature is too high, the plastic will explain.
(3)從塑料供應(yīng)商處獲得準(zhǔn)確的熔化溫度和成型溫度。
(3) Obtain accurate melting and forming temperatures from the plastic supplier.
(4)機(jī)筒上有三至五個(gè)加熱區(qū)。靠近料斗的加熱區(qū)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(shí)際熔化溫度通常高于加熱器的設(shè)定值，主要是由于背壓和螺桿旋轉(zhuǎn)產(chǎn)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(jì)可以測(cè)量溶液的實(shí)際溫度。
(6) The probe thermometer can measure the actual temperature of the solution.
設(shè)置模具溫度
Set mold temperature
(1)從塑料供應(yīng)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(jì)測(cè)量
(2) Mold temperature can be measured by thermometer
(3)冷卻液的溫度應(yīng)設(shè)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(jì)南模具加工和模板之間設(shè)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(zhì)量，有時(shí)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(shè)置螺桿的注射焦點(diǎn)
Set the injection focus of the screw
(1)注射終點(diǎn)是從充填階段切換到保壓階段時(shí)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(chǎn)品表面可能會(huì)出現(xiàn)凹痕。一般情況下墊料的長(zhǎng)度設(shè)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(jì)南注塑模具廠家經(jīng)驗(yàn)表明，如果在本步驟中將注射點(diǎn)設(shè)置為填充型腔的2/3，可以防止注塑機(jī)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.
