What are the factors affecting the production of plastic turnover boxes?

The plastic turnover box is made of high-pressure high-density polyethylene (HDPE) and polypropylene (PP) by injection molding with high impact strength. Its product quality is good and the design scheme is reasonable. It is mainly used for the delivery, storage, transportation, circulation and processing of factory freight logistics. Plastic turnover boxes are widely used for orderly stacking, convenient parts turnover and convenient supervision.

Some plastic cases are also equipped with case covers, and some freight logistics case covers are independently matched. Several similar types of freight logistics case goods are common; Most cases are molded by one-time injection molding. Plastic turnover boxes are mainly used in clothing, hardware, machinery, electronics, food, aquatic products, chemical industry, instrumentation, aquatic products, logistics and warehousing and other industries. They can be used to store food, clean and facilitate the turnover of spare parts, pile up neatly, and facilitate supervision.

Before the melt freezes at the gate, the holding time has a great influence on the specification accuracy of the commodity. The key to the holding time is the raw material temperature, mold temperature and the specification of key runner and gate. If the specifications and processing conditions of the sprue and gate are normal, the pressure value is generally taken as the basis, and the scope of shrinkage fluctuation is small.

In the future, the plastic turnover box will cooperate with the industrial control automation, improve the overall level, develop intelligent, efficient and low consumption goods, and realize the industrialization development. Therefore, technological innovation should be carried out to minimize the forming cycle of each relevant time on the premise of quality and quantity guarantee, so as to ensure that the products can maintain a good forming state.

The cooling time will also affect the release of the plastic turnover box. Refrigeration time shall ensure that the demoulding principle of plastic turnover box commodities will not change, generally about 30-120 seconds. If the cooling time is too long, it will not only reduce the cost efficiency, but also cause difficult demoulding of complex parts, and even produce demoulding stress during demoulding.
