1. Injection molding period of plastic parts, which includes plastic time and product cooling time, which have a great influence on the quality of the product. Before the injection molding plastic parts are processed and produced, we should determine the product molding cycle by the sample pattern and other methods.
2, the temperature of the plastic mold, different plastic particles, the temperature and speed of the crystallization are not the same, and the appearance, deformation, size, plastic mold, etc. of the product have different requirements, which makes the temperature of the plastic mold In the case of using different plastics, product requirements, etc., the control of the mold temperature is different.
3, molten plastic injection pressure, plastic in the process of filling the mold cavity is very resistant, which makes the size of the injection pressure directly determines the size, weight, density, appearance of the product.
4, the injection speed, the speed of the injection speed has an important impact on the appearance quality of the product. The injection speed is generally achieved by adjusting the amount of oil supplied to the injection cylinder per unit time.
5. The temperature of the barrel and the temperature of the melt. The temperature of the melt can be measured at the nozzle or by the air jet method. The melt temperature plays a major role in the flow properties of the melt. The plastic has no specific melting point. The so-called melting point is a The temperature range in the molten state. The control of both temperatures also plays an important role in the quality of the product.
Process parameters that require attention in the processing of injection molded plastic parts generally include these. These process parameters are not divided into primary and secondary. Each factor is very important for the quality of plastic products. It is necessary for plastic engineers to reasonably formulate process parameters according to different products and different types of plastics.
