Prototype spraying knowledge, do you know? Next, the Xiehe prototype processing factory will give you a brief introduction.

When the prototype is painted, it must first go through the whiteboard polishing process. When polishing, the smoothness of the product must be considered, whether the corners are in place, and the traces of bonding should not be exposed obviously. We need to spray dust before we polish it enough to be painted. Coloring generally requires numbers. This is based on international standards, which are the same all over the world. This has a qualitative standard for color regulations. Hand oil injection is a very frequently used process, and it is often introduced on the hand model making website. Because the process of making a first board requires a lot of post-processing in addition to good machinery and equipment, which includes manual polishing and assembly, oil spraying, coloring and silk screen printing, etc.

The way of spraying oil on the handboard is to use air compression to form an airflow. When passing through the paint cavity, the paint is brought into the suction pipe and sprayed out through the paint nozzle to form a mist-like oil layer. This oil layer is sprayed on the handboard product. When it is in the middle, the acne will appear uniform, and the surface gloss is quite good.

The advantage of this method of coloring, in addition to the gloss, is that many gaps or dead corners of the product can also be sprayed on relatively hidden places with a very uniform effect. The disadvantage is that it is a waste of paint, and its paint usage rate is about 50%.

It is very difficult to color some prototypes, such as Saigang, which is made of PP, which is not good. After coloring, it is not very sticky, and it will fall off as soon as you rub it. So basically the products made of Saigang material or the first board made of PP material are not colored. Saigang is used for the processing of gears, and it is generally placed where it does not need to be colored, and it is assembled in the product. It's not from the exterior parts. In the production of prototype models, if it is an appearance prototype, the requirements for the appearance of the product are relatively high. However, because the material used in processing will only have one color, if a colorful effect is required, it must be sprayed and painted in the later stage to achieve it. The colored product has a good appearance, and at the same time can increase the friction performance of the product, and protect the internal structure of the part from being easily worn off.

The above content is the spraying knowledge about prototypes summarized by the Xiehe prototype processing factory for everyone, and I hope it will be helpful to everyone.
