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.

　　这种方式是使用压缩空气喷射,形成一种气流,腔通过漆,漆成稻草,喷漆后雾喷嘴形成一个水库,水库的时候喷洒到板材产品,痤疮是统一的,表面光泽度也很好。

　　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.

　　这种上色方式的优点，除了光泽度外，还有很多产品的缝隙或死角等相对隐蔽的地方都可以做到对喷涂和非常均匀的效果。缺点是比较浪费的油漆，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%.

　　在手板的生产中，如果是手板的外观，对产品的外观要求都比较高。但是因为在加工过程中使用的材料只会有一种颜色，如果你需要一种彩色的效果，你必须使用后期的注射绘画才能达到。该有色产品具有良好的外观效果，能提高产品的摩擦性能，保护零件内部结构不容易磨损。上色时，我们可以根据产品的不同要求来调整不同的颜色。不要觉得实现客户的结果是一种束缚。这也是掩盖表面缺陷的好方法。

　　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.
