Technical Difficulties in Injection Molding Shell Processing

At present, plastic injection molding products account for about 30% -40% of the entire plastic products market, and their high-efficiency and high-quality molding methods have been favored by many enterprises! And the precision of the plastic products produced is also higher than that produced by other molding methods, and the injection molded shell is an important branch of the entire injection molded product.

The shells of many common items in our daily lives are almost made of various plastics, such as phone shells, refrigerator shells, computer shells, air conditioner shells, etc! They are all produced through injection molding methods. The outer shell of a product is also the first link that consumers come into contact with, regardless of its performance? How beautiful is it? How is the craftsmanship? If the quality of the product's casing does not meet the standards, it will leave a bad impression on consumers and directly affect whether the product can be sold successfully. Therefore, major manufacturers have very strict requirements for the quality of product casings. So, what are the common processes we need to pay attention to when producing injection molded casings?

The dimensional tolerance of the injection molded shell, if the size differs too much from the size of the product itself, that is, the gap is large, it is easy for consumers to discover and leave the impression of inferior products. Secondly, the smoothness of the surface of the injection molded casing is closely related to the design of the injection mold and the raw materials used for injection molding. When consumers touch the casing, they will inevitably feel comfortable. Thirdly, the spray painting of the injection molded casing must be uniform, and any odors must be promptly eliminated. Fourthly, the strength of the injection molded casing must be durable. Products such as general electrical appliances require at least several decades of use, during which they are inevitably bumped and bumped. Therefore, injection molded casings must have certain impact resistance! As long as we pay attention to these process issues when producing injection molded shells, it is easy to produce qualified products.
