How to inspect the molds for injection molding
To ensure that the injection molding molds meet the standards, it is necessary to consider the application regulations and design schemes, as well as ensure their service life. Normal construction and production require quality assurance of mold specifications from the aspects of product quality, mold structure, and injection molding process regulations. On the other hand, the transformation of household appliances has also driven the deep development of the plastic mold industry for household appliances. At present, large and fine injection molding molds have gained more and more attention from enterprises. Unintentionally, it has put forward higher requirements and tests for the domestic plastic mold industry. So how to inspect the injection molding mold?
1. The surface of the product is not allowed to have defects, insufficient materials, burning, whitening, peaking, foaming, cracking, baking, or wrinkling.
2. Generally, the welding length of circular holes should not exceed 5 millimeters, and the welding length of irregular holes should be less than 15mm. The compressive strength of welding can be tested based on the coefficient of action.
3. The surface appearance is not allowed to be folded. The flatness of general small products is less than 0.3 millimeters.
