At present, plastic injection molding products occupy about 30% - 40% of the whole plastic products market. Their high-efficiency and high-quality molding methods are loved by many enterprises! And the precision of the plastic products produced is also higher than that produced by other molding methods, and the injection molding shell is an important branch of the whole injection molding products.

我们生活中很多常见的物品的外壳几乎都是由各种塑料制成，如手机外壳、冰箱外壳、电脑外壳、空调外壳等！其都是通过注塑加工成型方法生产的。产品的外壳也是消费者接触到产品的一个环节，不管产品性能如何？美观如何？工艺如何?要是产品的外壳质量不达标的话，将会给消费者留下不好的印象，直接关乎到产品是否能够销售成功，所以各大厂家对产品外壳的质量要求是非常严格的，那么我们在注塑加工外壳生产的时候又有哪些常见的工艺要注意呢？

The shell of many common objects in our life is almost made of various plastics, such as mobile phone shell, refrigerator shell, computer shell, air conditioning shell and so on! They are all produced by injection molding. The shell of the product is also the first link for consumers to contact the product, regardless of the product performance? How beautiful? How about the process? If the shell quality of the product does not meet the standard, it will leave a bad impression on consumers, which is directly related to whether the product can be sold successfully. Therefore, major manufacturers have very strict requirements for the quality of the product shell. What common processes should we pay attention to when we produce the injection molding shell?

注塑加工外壳的尺寸公差，假如尺寸和产品本身的尺寸相差太大，也就是缝隙很大，很容易让消费者发现，并留下劣质产品的印象。

The dimensional tolerance of injection molding shell, if the size is too different from the size of the product itself, that is, the gap is very large, it is easy for consumers to find and leave the impression of inferior products.

注塑加工外壳表面的光洁度，当消费者触摸到外壳的时候，必然要留下舒服的感觉，光洁度和注塑模具设计和注塑原材料有很大的关系。

The surface finish of injection molding shell must leave a comfortable feeling when consumers touch the shell. The finish is closely related to the design of injection mold and injection raw materials.

注塑加工外壳的喷漆必然要均匀，异味也要及时的。

The painting of injection molding shell must be uniform, and the peculiar smell should be eliminated in time.

注塑加工外壳的强度必然要耐用，像一般的电器之类的产品少都要用数十年的时间，这期间难免要磕磕碰碰，所以注塑加工外壳要有必然的冲击性等！只要我们在生产注塑加工外壳的时候注意到这些工艺问题，就很容易生产出合格的产品。

The strength of the injection molding shell must be durable. Products such as general electrical appliances will take at least decades. It is inevitable to bump during this period, so the injection molding shell must have certain impact! As long as we pay attention to these process problems when producing injection molding shell, it is easy to produce qualified products.
