How to inspect injection molding molds?
To ensure that the injection molding molds can meet the standards, it is necessary to consider the application regulations and design schemes, and to ensure its service life. Normal construction and production must be carried out from the aspects of product quality, mold structure, and injection molding process regulations. Quality assurance of mold specifications. On the other hand, the transformation of home appliances has also driven the in-depth development of the home appliance plastic mold industry. At present, large-scale and sophisticated injection molding molds have been favored by more and more companies. Unintentionally put forward higher requirements and tests for the domestic plastic mold industry. So how to inspect injection molding molds?
1. The surface of the product is not allowed to have defects, lack of material, burning, whitening, peaking, bubbling, cracking, baking, and wrinkling.
2. The length of the general annular hole welding is not more than 5 mm, and the length of the special-shaped hole welding is less than 15 mm. The compressive strength of the welding can be tested according to the action coefficient.
3. The surface appearance is not allowed to shrink. Generally, the flatness of small products is less than 0.3 mm.
