注塑模具廠家對結晶型和非結晶型塑料如何處理?

來源:http://m.xjfff.com/ 日期:2022-04-30

  注塑模具加工廠的模具應根據成型不同的塑料品種,設置模具冷卻或加熱裝置的模溫控制系統,那么注塑模具廠家對結晶型和非結晶型塑料如何處理?
  The mold of the injection mold factory should be set up according to the different plastic varieties of the mold cooling or heating device of the mold temperature control system, so how to deal with the crystallized and amorphous plastic of the injection mold manufacturer?
  由于結晶型塑料具有冷卻時施放熱量多、冷卻速率快、結晶度低、收縮小和透明度高的特點,成型時需要充分冷卻。結晶度與注塑件壁厚有關,注塑件壁厚小時冷卻快、結晶度低、收縮小和透明度高。
  Due to the characteristics of crystalline plastic cooling heat release, cooling rate, low crystallinity, shrinkage and high transparency, molding needs to be fully cooled. Crystallinity is related to the wall thickness of injection molded parts. When the wall thickness of injection molded parts is small, cooling is fast, crystallinity is low, shrinkage and transparency are high.
  反之,注塑件壁厚大時冷卻慢、結晶度高、收縮大以及物理性能和力學性能好,所以結晶性塑料須按照要求控制模溫,一般結晶型塑料為不透明或半透明,如聚酰胺(PA)。非結晶型塑料為透明的,如有機玻璃。但也有例外,如結晶型塑料聚。
  On the contrary, when the wall thickness of injection parts is large, cooling is slow, high crystallinity, shrinkage and physical and mechanical properties are good, so the crystalline plastic must be controlled in accordance with the requirements of the mold temperature, general crystalline plastic is opaque or translucent, such as polyamide (PA)。 Amorphous plastics are transparent, such as plexiglass. But there are exceptions, such as crystalline plastic polymer.
  此外,注塑模具加工廠對成型注塑件主澆道長的模具,需要采用加深型澆口套和熱流道來提高熔體充模的溫度,用于改善塑料熔體的流動性。對于流程長的厚壁或成型面積大的注塑件,為了保證塑料熔體的充分填充,應考慮設置加熱裝置:而對薄壁注塑件,可依靠模具自身的散熱而不需要設置冷卻裝置。
  In addition, the injection mold factory needs to use deep gate sleeve and hot runner to improve the melt filling temperature and improve the fluidity of plastic melt for the mold with long main gate of injection molding parts. For injection parts with long thick wall or large molding area, in order to ensure full filling of plastic melt, heating device should be considered. For injection parts with thin wall, cooling device is not needed to rely on the heat dissipation of the mold itself.
  而濟南注塑加工廠家對于黏度低與流動好的塑料,如聚苯乙烯(PS)、聚氯乙烯(PVC)、聚乙烯(PE)、聚酰胺(又稱尼龍PA)和聚丙烯(PP)等黏度低的塑料,需對模具加裝冷卻裝置,一般情況下是采用溫水冷卻;為了縮短冷硬固化的時間,也可采用冷(室溫)水冷卻。
  And Ji 'nan injection molding manufacturers for low viscosity and good flow of plastic, such as polystyrene (PS), polyvinyl chloride (PVC), polyethylene (PE), polyamide (also known as nylon PA) and polypropylene (PP) and other low viscosity plastic, need to add cooling device for the mold, under normal circumstances is the use of warm water cooling; In order to shorten the time of cold and hard curing, cold (room temperature) water cooling can also be used.
