Plastic products are very common in production errors, and there are various color products. However, during the injection molding process of the same batch of products, the phenomenon of color deviation is often found. What is the reason for this? How to solve it? Today, the editor of Huanke Precision will answer this question for you.

Mold temperature refers to the mold cavity surface temperature in contact with the product during injection molding. Because it directly affects the cooling rate of the product in the mold cavity, and thus has a great influence on the intrinsic performance and appearance quality of the product. In this paper, five points of influence of mold temperature on quality control of injection parts are discussed. The content of the package material system for excellent products is adopted for friends' reference

Product design: Plastic product processing holds rounding and increases the demolding slope. Mold: 1. Mold surface polishing. 2. Pull the white status growth thimble. 3. Confirm that the parting surface has no inverted buckles and air spurs, and repair it with oil stone. Injection molding process: 1. Under the premise of thorough filling of the clad product, accept the lowest possible injection pressure. 2. Confirm that there is no problem with the size and appearance of the product, reduce the holding pressure, holding time or cancel the holding pressure. 3. Adjust mold temperature and cooling time. When we are in the injection molding of plastic finished products, we usually encounter the idea of product whitening, we can first analyze the whitening from the methods of man, machine, material, method and ring, and classify and summarize all the components that affect the product; Re-examine the process opened up by the product.

General precision injection molds have two indicators, namely equipment accuracy and mold error. The former is difficult to compare due to the difference in size and product thickness, and represents the comprehensive level of injection molding machines. Generally, the weight repetition error of ordinary injection molding machines is 1%. A good machine can reach 0.8%, less than 0.5% is a precision machine, and less than 0.3% is an ultra-precision machine. So what are the main factors affecting precision injection mold products?

The lightweight performance of PEEK materials and the comprehensive performance potential behind them are exciting. PEEK offers some representative products for the aviation industry, such as the PEEK polymer injection molded parts used to replace the expensive production of aluminum brackets.

The traditional five-axis CNC machining process may cause waste parts due to temperature or other processing techniques. Unlike ordinary metal processing, some rubber or plastic molds cannot be recycled after being scrapped. For enterprises The five-axis processing of rubber molds may greatly affect the net profit, but the choice of five-axis processing of rubber molds shows many advantages.
