Several issues that should be paid attention to in injection molding?
Injection molding is a very complicated process, which 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. What are some issues that need special attention in the process of injection molding? Below, Nanya TEDA Injection Mold will introduce several issues that should be paid attention to in injection molding.
1. Injection speed
The speed of injection has an important influence on the final 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.
2. Molding cycle
This includes injection time and product cooling time. The effective control of these times has a profound impact on the quality of the product. Before the injection molding production, the two-color mold manufacturer should clarify the product molding cycle through the sample style and other methods.
3. Barrel temperature and melt temperature
The melt temperature can be measured at the nozzle or by air injection. The melt temperature plays a major role in the flow properties of the melt. 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 vital role in the quality of the product.
4. Molten plastic injection pressure
Plastic faces great resistance in the process of filling the mold cavity, which makes the injection pressure directly determine the size, weight, density, appearance, etc. of the product! If any of these factors are affected, the product will become scrapped. This requires the injection engineer of the two-color mold manufacturer to reasonably define the injection pressure control based on the comprehensive factors of the product.
