Several Issues to Pay Attention to in Injection Molding Processing

Injection molding is a quite complex process that involves several professional knowledge such as physics and chemistry. Therefore, we need to pay special attention to it. Otherwise, if we are not careful, many defects will occur, which will affect the normal efficiency of plastic parts processing.
1. Injection speed
The speed of injection has a significant impact on the final appearance quality of the product. The injection speed generally needs to be achieved by adjusting the amount of oil supplied to the injection cylinder per unit time.
2. Forming cycle
This also includes injection molding time and product cooling time, and the effective control of these times has a profound impact on the quality of the product. Before injection molding production, manufacturers of dual color molds should clarify the product molding cycle through sample styles and other methods.
3. Barrel temperature and melt temperature
The temperature of the melt can be measured at the nozzle or using the air jet method. The melt temperature plays a major role in the flow performance of the melt, and plastic does not have a specific melting point. The so-called melting point is a temperature range in a molten state. The control of these two temperatures also plays a crucial role in the quality of the product.
4. Molten plastic injection pressure
Plastic faces great resistance during the process of filling the mold cavity, which directly determines the size, weight, density, appearance, etc. of the product due to the injection pressure! If any of these factors are affected, the product becomes a scrap. This requires injection engineers from dual color mold manufacturers to reasonably define injection pressure control based on the comprehensive factors of the product.
