Retractble ceiling fan hardware accessories manufacturers how to correctly control the pressure injection process

How to properly control the pressure injection molding process of retractble Ceiling fan hardware accessories manufacturers generally includes the above-mentioned process parameters, these process parameters are not divided into major and minor, each factor is critical to the quality of injection products The important thing is that the injection molding engineer needs to reasonably formulate the reference of the process parameters based on different products, different types of plastics and other product information, which has guaranteed the quality requirements of the products.

The injection molding process needs to control the temperature of the barrel, nozzle temperature and mold temperature. The first two temperatures mainly affect the plasticization and flow of plastics, while the latter temperature mainly affects the flow and cooling of plastics.

The application range of plastic parts is getting wider and wider, from simple tableware, kitchen utensils to complex mechanical parts , electronic product shells, etc. Plastic parts are used, but for plastic parts with high precision requirements such as electronic product shells, injection molding processing At the time of injection molding, the accuracy requirements must be paid attention to from the beginning of mold manufacturing.

The common holes in the processing of injection molded parts are through holes, blind holes, shaped holes (holes with complex shapes) and threaded holes. These holes should be set in places where the strength of the plastic parts is not weakened. Between the holes and the holes, the holes and There should be sufficient distance between the side walls, and the relationship between the two holes of the thermosetting injection molded parts and the thermoplastic injection molded parts and between the holes and the side walls can be found in the relevant industry tables.

Too large wall thickness in the processing of plastic parts not only wastes raw materials, but also increases the molding time for thermosetting plastic molding.
