供应水篦子生产完成后，会出现表面不光泽的现象，出现这种现象的原因有很多种，主要原因有：有些水篦子模具模具生产出来表面无光泽,是因为聚丙烯质料塑化熔融质量不均匀,应当恰当进步注塑机机筒加热温度或进步螺杆作业背压再就是聚丙烯质猜中含的水分偏高,应当对质料枯燥处理,是质猜中含水分在答应目标内再就是模具内成型制品作业面粗糙或有水珠,应当研磨抛光作业面,进步型腔表面光亮度还有就是聚丙烯质料附加料配加不妥,应当调整替换还有聚丙烯质猜中混有杂质多,不清洁模具温度偏低,应恰当进步模具温度就是脱模剂涂层太厚,用量过多。水篦子模具的生产过程关于模具以后的运用起着很重要的推进效果，如果想要在原有的基础上进步模具的运用寿命，需要留意的有：当塑料制件规划完成并选定所用资料后,就需要考虑是运用单型腔模具仍是多型腔模具。浇注体系规划是否合理不仅对塑件功能、尺度、结构、内外在质量等影响很大
供应水篦子There are many reasons for this phenomenon. The main reasons are as follows: some water grate molds produce glossy surface, because the plasticizing and melting quality of polypropylene is not uniform, so the heating temperature of injection molding machine barrel should be properly improved or the screw work should be improved. Secondly, the moisture content in the polypropylene guess is too high, and the material should be dull, and the moisture content in the guess is within the allowable target thirdly, the working surface of the molding products in the mold is rough or has water lets, and the working surface should be grinded and polished to improve the brightness of the cavity surface thirdly, the addition of the polypropylene additives is inappropriate and should be adjusted. Replacement and polypropylene guessed mixed impurities, unclean mold temperature is low, should properly improve mold temperature finally, the release agent coating is too thick, too much. The production process of the water grate mold plays an important role in promoting the use of the mold. If you want to improve the service life of the mold on the original basis, you need to pay attention to: when the plastic parts planning is completed and the information used is selected, you need to consider the use of single cavity mold or multi-cavity mold. Whether the ing system planning is reasonable or not has a great influence on the function, scale, structure, internal and external quality of the plastic parts.
