Hand spray is a common process. Because the process of manual production, in addition to a good machine and equipment, also needs a lot of post-processing, including manual polishing assembly, oil spray color printing, etc. The following is an air compression spraying method for handboard processing.

　　這種方式是使用壓縮空氣噴射,形成一種氣流,腔通過漆,漆成稻草,噴漆后霧噴嘴形成一個水庫,水庫的時候噴灑到板材產品,痤瘡是統一的,表面光澤度也很好。

　　This way is to use compressed air jet to form a kind of air flow. The cavity is painted into straw through paint. After painting, the spray nozzle forms a reservoir. When the reservoir is sprayed to the plate products, acne is uniform and the surface gloss is good.

　　這種上色方式的優點，除了光澤度外，還有很多產品的縫隙或死角等相對隱蔽的地方都可以做到對噴涂和非常均勻的效果。缺點是比較浪費的油漆，其油漆利用率大概在50%左右。

　　The advantages of this way of coloring, in addition to glossiness, there are many product gaps or dead corners and other relatively hidden places can achieve spraying and very uniform effect. The disadvantage is that the paint is wasted, and the paint utilization rate is about 50%.

　　在手板的生產中，如果是手板的外觀，對產品的外觀要求都比較高。但是因為在加工過程中使用的材料只會有一種顏色，如果你需要一種彩色的效果，你必須使用后期的注射繪畫才能達到。該有色產品具有良好的外觀效果，能提高產品的摩擦性能，保護零件內部結構不容易磨損。上色時，我們可以根據產品的不同要求來調整不同的顏色。不要覺得實現客戶的結果是一種束縛。這也是掩蓋表面缺陷的好方法。

　　In the production of handboards, if it is the appearance of handboards, the appearance requirements of products are relatively high. But because the material used in the processing will only have one color, if you need a color effect, you must use later injection painting to achieve. The colored product has good appearance effect, can improve the friction performance of the product, and can protect the internal structure of the parts from wear. When coloring, we can adjust different colors according to different requirements of products. Don't feel that achieving the customer's results is a constraint. This is also a good way to cover up surface defects.
