To ensure that the injection molding mold can meet the standards, it is necessary to consider application regulations and design plans, as well as ensure its service life. Normal completion and production require quality assurance of the mold specifications from aspects such as product quality, mold structure, and injection molding process regulations. On the other hand, the transformation of home appliances has also driven the deep development of the home appliance plastic mold industry. At present, large and fine injection molding molds have gained increasing attention from enterprises. Unintentionally, it has put forward higher requirements and tests for the domestic plastic mold industry. So how do we accept injection molding molds?
1. The surface of the product is not allowed to have defects, lack of material, burning, whitening, peaking, bubbling, cracking, baking, or wrinkling.
2. Generally, the length of circular hole welding should not exceed 5mm, and the length of irregular hole welding should be less than 15mm. The compressive strength of welding can be tested based on the coefficient of action.
3. The surface shape does not allow folding. The flatness of general small products is less than 0.3 millimeters.
