Transparent PC injection molding products crack near the gate how to do

Cracking of injection molded products near the gate is a common problem, which will not only affect the quality of products, but also increase the production cost of enterprises. This article will give you some advice on how to solve the problem of cracking of transparent PC injection molded products near the gate.

First of all, let's analyze the reasons for the cracking of injection molded products near the gate. This may be caused by many factors such as material quality problems, unreasonable gate design, and improper molding temperature. Understanding the causes of cracking is critical for us to develop solutions.

In order to solve this problem, we can start from the following aspects:

Material selection: Select high quality and suitable PC materials. High-quality materials usually have high toughness, heat resistance and crack resistance, which can effectively reduce the risk of cracking of products near the gate.

Gate design: Reasonable gate design to ensure that the sol can flow evenly at the gate to avoid local stress concentration. At the same time, it is considered to add the structure of gate tie rod to enhance the mechanical strength of the gate area.

Molding process optimization: According to the actual production situation, reasonable setting of molding process parameters, such as temperature, time, pressure, etc. By adjusting the parameters, the best forming process combination is found to reduce the cracking phenomenon of the product near the gate.

Equipment maintenance: Regular maintenance and maintenance of injection molding equipment to ensure that the equipment is in good working condition. Check and replace worn parts in time to avoid cracking near the gate due to equipment problems.

By improving materials, optimizing gate design and molding process, the problem of cracking of transparent PC injection molded products near the gate can be effectively solved. This not only helps to improve the quality of products, reduce production costs, but also improves the competitiveness of enterprises. When implementing these solutions, use them flexibly according to the specific situation. At the same time, pay attention to the training of employees, so that they better understand and master these methods, in order to play a full role in actual production.
