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.
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.
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%.
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.
