After the head is crushed, the addition proportion should be controlled well. It is not allowed to mix too much in a single time. The black and color should be added less. When making black, the choice of color masterbatch is very important
During injection molding, the temperature should not be adjusted too high by the staff. In that case, the tie strips are brittle, and the molecular structure of nylon is completely destroyed, which has a great impact on the tensile force
The clamping force, injection time and glue injection time must be adjusted properly. The molds are now fully automatic, and the output has been improved. However, pay attention to bubbles. If the injection time is short, the products are prone to bubbles, affecting the appearance
When changing the mold, the products should be tested one by one, especially for small specifications. Pay attention to whether there are missing teeth, reverse teeth, eccentricity, etc.
