The company found the following problems in the PBT 30% Engineering Plastics injection molding:
1. The red circle has burrs, with a step difference of about 0.05;

2. The appearance of the red circle is uneven and the knife lines are serious;

3. The red circle has fiber marks and serious air trapping. This article explores the steps the company has taken to address these issues.

First of all, in response to problem 1, the company has taken measures for fitters to check and correct molds. This is a common method, which can effectively improve the quality of the product by checking and correcting the deviation of the mold. After the fitter inspected the mold, he found row burrs, and then corrected the mold to solve the problem.

Secondly, in response to problem 2, the company has taken measures to save mold and deal with knife lines. It is also a common method to improve the appearance and quality of the product by dealing with the problems of the mold surface. When dealing with knife lines, the company may have adopted various methods, such as grinding, grinding, etc., to eliminate knife lines and obtain a smooth surface.

Finally, in response to question 3, the company has taken additional exhaust measures. This is a method that can help reduce or eliminate air-trapping problems during the injection molding process. By adding exhaust, the possibility of fiber marks and trapped air can be reduced or eliminated, thereby improving the quality of the product.

In addition to the above problems, the company also noticed that the product has warping deformation after PBT 30% Engineering Plastics injection molding, and requested to control it within the flatness range. In addition, the product needs to be laser welded after injection molding. In this case, the injection molding machine needs to be thoroughly cleaned with natural color materials (such as PP) before injection molding to ensure that no foreign matter or impurities are attached to the material, thereby ensuring the quality of laser welding.

To sum up, when facing the quality problems of the solenoid valve housing project, the company has adopted a series of effective measures to solve these problems. These measures include inspecting and correcting molds, dealing with mold surface problems, additional venting, and proper cleaning processes. Through these measures, the company has successfully improved the quality of its High-Performance Engineering injection molding and provided customers with more reliable and high-quality products.
