What are the surface treatment processes for prototype models

enterprises need to make prototypes when developing new products to detect whether product design is feasible and find out where product design is insufficient, however, to further improve and design a perfect product, there are three main purposes for prototyping: 1. Verify the structure and appearance of the product, size, etc. 2. Participate in the exhibition 3. Sell as a finished product.

The prototype needs a surface treatment process to sell it as a finished product, after some process treatment, it looks very similar to the real finished product. If you don't do surface treatment, the appearance effect is very bad. Here are some surface treatment techniques commonly used in the prototype:

1. Manual processing: the prototype surface that has just been processed from the machine will have knife marks and burrs, and it needs to be polished smoothly with sandpaper.

2. Fuel injection: the prototype sample made can be sprayed with color in the environment of the dust-free oil room according to the customer's requirements, making the prototype sample more vivid and vivid, increasing the realism of the prototype sample.

3. Silk screen printing: print the text or pattern requested by the customer on the prototype surface.

4. Plating: the sample before plating must be very smooth, there must be no trace of impurities, and then soaked in the chemical potion. This operation is divided into: Shuidu and vacuum crossing. Generally, plastic and metal materials can be plated. The effect of plastic plating is better, but the electroplating of pc materials is difficult.

5. Sand blasting: the effect of spraying a layer of sand and granular on the surface of the prototype makes the prototype sample look better.

6. Oxidation: oxidation reaction occurs on the surface of aluminum alloy, forming a layer of film, so that the product is not easy to scratch.

7. Drawing: pull out a fine mark on the surface of the prototype to make the sample feel better.

8. Over UV: spray a layer of transparent oil on the surface of the prototype and dry it with UV light to make the product brighter and less flower-friendly, just like a protective layer.
