How to make a turnover box mold ?

How to make a turnover box mold First of all, to produce a four-in-one turnover box mold, pre-hardened steel with a hardness higher than 45 must be used as the mold base. Secondly, the friction and guide parts of the turnover box mold must be precision machined, and no manual work can be used. HDPE materials with low melt index must be used. Then, make sure the cooling system works well. It is necessary to manufacture two durable hydraulic drives to cooperate with the automatic ejection of the machine, so that the ejection action during mold opening can be smoother. For different types of molds, precision mold processing is required to ensure the accuracy of mold operation, otherwise the mold will not be able to operate at high speed. Sino turnover box molds all use accelerators to increase the injection speed of the melt. The design of plastic turnover box mold is also very important. The ejection method of the fruit turnover basket mold is better to be designed as mechanical ejection, so that the e
