As a part of our daily life, the use of plastic products has become increasingly widespread, and there are also more and more manufacturers engaged in the production and processing of plastic products. Changzhou injection molding is a type of plastic processing technology that plays a significant role in our daily lives. However, products processed through Changzhou injection molding also exhibit shortcomings. As mentioned here, Changzhou injection molding manufacturers will introduce the reasons for this situation.

In practical production work, not all products can be qualified, and there are definitely defective products. So what are the reasons for the defects in the injection molding process? Firstly, the reason for the lack of product filling.

There are many reasons for the formation of filling deficiency: 1. Poor exhaust of the mold cavity, blockage of the pouring system, short injection time, poor fluidity of the material, resulting in filling deficiency;

2. The lack of filling caused by the low temperature of the barrel, nozzle, and processing machine.

3. The number of runners or gates is too small, which is caused by improper orientation. Next is the overflow of the product, which is caused by excessive filling and excessive fluidity of the material. Afterwards, there are bubbles inside the product, which is caused by poor plastic drying. Therefore, prior inspection is required during processing.

Changzhou injection molding processing

Injection molded parts processing is widely used in our daily life, and the two-layer injection molding process is one of the injection molded parts processing processes. The two-layer injection molding process refers to the skillful injection molding of two different plastic materials together, which has the following three outstanding advantages: firstly, the change in touch sensation. Some of the previous injection molded products did not achieve the tactile experience of consumers, while the two-layer injection molding process can directly improve the tactile feel. The products it creates are more like carefully crafted handicrafts. 2、 More user-friendly. The product manufactured through a two-layer injection molding process not only greatly improves its lifespan, but also enhances its strength and wear resistance. 3、 Visual impact. The beauty of the appearance directly affects our desire to purchase, and the two-layer injection molding process can make the appearance color of the product more specific. The sales volume of the product will greatly increase.
