Injection molding is a very complicated process, which involves several professional knowledge such as physics and chemistry, so we need to pay special attention, otherwise, if we are not careful, many defects will occur, which will affect the normal efficiency of plastic parts processing . In the process of injection molding, do some problems need special attention? The following Nanya Taida 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 impact on the final appearance quality of the product.
The injection speed generally needs to be realized by adjusting the amount of oil supplied to the injection cylinder per unit time. 2. The molding cycle includes injection molding time and product cooling time. Effective control of these times has a profound impact on product quality. Two-color mold manufacturers should clarify the product molding cycle through the sample style and other methods before injection molding production.
3. Barrel temperature and melt temperature Melt temperature can be measured at the nozzle or by air injection method. The melt temperature plays a major role in the flow properties of the melt. Plastic has no specific melting point. The so-called melting point is a melting point. state temperature range. The control of the temperature of the two 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 size of the injection pressure directly determine the size, weight, density, appearance, etc. of the product! Affect any of these factors The product then becomes scrap.
This requires the injection engineer of the two-color mold manufacturer to reasonably define the injection pressure control according to the comprehensive factors of the product.
