Difficulties in plastic shells injection molding

In our life, there are many common items of shells are basically made of plastic, such as mobile phone shells, refrigerator shells, computer shells and so on. These are produced by injection molding methods. Because these shells are directly in contact with the surface of the consumer's hand, regardless of product performance, appearance, and craftsmanship, if the quality of the shell of the product does not meet the standard, it will leave a bad impression on the consumer, which is related to the success of the product. The key is how the product feels, so we need to be very strict about the quality of the product's shell, so what difficulties will be encountered during this period?

1. The dimensional tolerance of the injection-processed shell. If the size and the product are too different, it will lead to a large gap, which makes it very uncomfortable to use, and it is easy for consumers to experience a bad experience.

2. The surface finish of the injection-processed shell, when consumers touch the shell, they must have a comfortable feeling. The finish is closely related to the design of the injection mold and the choice of raw materials.

3. The paint spraying requirements of the injection-molded housing will be very strict, and the odor should be dealt with in time, and the paint should be evenly sprayed.

4. The strength of the injection-processed casing must be durable. Compared with products such as general electrical appliances, it must be used for at least ten years. During this period, it will not accidentally bump the consumer, so the processed casing must have durability and impact resistance.
