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.

我們生活中（zhōng）很多常見的物品（pǐn）的外殼幾乎都是由各種塑料製成，如手機外（wài）殼、冰箱外殼（ké）、電腦外殼、空調外殼（ké）等！其都是通過（guò）注塑加工成型方法生產的。產品的外殼也是消費者接觸到產品的一個環節，不管產品性能如何？美觀如何？工藝如何?要是產品的外殼質量不達標的話，將會給消費者留下（xià）不好的印象（xiàng），直接關乎到產品是否能夠銷售成功，所以各大廠家對（duì）產品外殼的質量要求是非常嚴格的，那麽我們在注塑加工外（wài）殼生產的時候又有哪些常見的工藝要注意呢？

The shell of many common objects in our life is almost made of various plastics, such as mobiles phones 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?

注塑加工外殼的尺寸公差，假如尺寸和產（chǎn）品本身（shēn）的尺寸相（xiàng）差太大，也就是縫隙很大，很容易讓消費者發現，並留下劣質產品的印象。

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（gōng）外殼表麵的光（guāng）潔度，當消費者觸（chù）摸到（dào）外殼的時候（hòu），必然要留下舒服的感覺，光潔（jié）度和注塑模具（jù）設計（jì）和（hé）注塑原材料有（yǒu）很大的關係。

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.

注塑加工外殼的噴（pēn）漆必然要（yào）均勻，異味也要及時的（de）。

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

注塑加工外殼的強度必然（rán）要（yào）耐用，像一般的電（diàn）器之類的產品少都要用數十年的時間，這期（qī）間難免要磕磕碰碰，所以注塑（sù）加工外殼要有必然的衝擊性等！隻要我們在生產注塑加工外殼的時候注意到（dào）這些（xiē）工藝問題，就很容易生產出合格的產品。

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.
