What is the cause of the error in the PET Zipper Braided Sleeve?

With the improvement of the technology of Pet Zipper Braided Sleeve, the quality of the produced PET Zipper Braided Sleeve is getting better and better. In the daily production, sometimes some problems will be encountered, such as the produced PET Zipper Braided Sleeve are not as expected. , so what are the reasons for these errors?

1. It is very important to increase the molding temperature above the temperature of the mold. It is important to know that the higher the temperature of the molding mold, the Open Type Braided Sleeve can be formed according to the molding mold because of the temperature. The fluidity of the mold is also close to the grinding and has activities, and the fluidity of the raw material is relatively poor, and the size of the product after molding will not have an error relationship with the expected one!
2. We will apply a force to the Open Type Braided Sleeve during molding. Through a moderate force, we can compress the Open Type Braided Sleeve to a fixed size, so in terms of molding pressure, we must reasonably grasp a degree , For example, if the pressure is too large, the thickness will become thinner, and relatively speaking, the size will also become larger, and vice versa.
3. Sometimes it may be a problem with the design of the mold itself. The design is not rigorous and qualified, so no matter how you adjust the size during production, you will find some errors, because you must pay attention to the rigor of the mold during mold opening. There is no slight error with the size of the product. Generally speaking, problems with the mold itself are relatively rare in the PET Zipper Braided Sleeve production industry, but we cannot rule out this reason.
