Fan Shida explained: What processes are included in plastic injection molding?

The main precautions for plastic injection molding and the processes included therein: 1. The molding cycle of injection molding products, which includes injection molding time and product cooling time, and the effective control of these times has a profound impact on the quality of products. Before the injection molding production, we should clarify the product molding cycle through the sample pattern and other methods. 2.,the temperature of the injection mold, different plastic particles, the temperature and speed of crystallization are different, and the appearance, deformation, size, and rubber mold of the product have different requirements; This makes the temperature control of the injection mold different in the case of different plastics, product requirements, etc. 3. Molten plastic injection pressure, plastic is facing great resistance in the process of filling the mold cavity, which makes the size of the injection pressure directly determine the size, weight, density, appearance and so on of the product! If any of these factors are affected, then the product becomes scrapped. This requires the injection engineer to reasonably define the injection pressure control according to the comprehensive factors of the product. 4. the injection speed, the speed of the injection 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. Barrel temperature and melt temperature, melt temperature can be measured at the nozzle or use air injection method to measure, melt temperature plays a major role in the fluidity of the melt; There is no specific melting point for plastic molds, and the so-called melting point is a temperature range in a molten state.The temperature control of both plays a crucial role in the quality of the product.
