Surface treatment of prototype models

The surface treatment technology prototype of the prototype in the work, in addition to requiring a reasonable fit of the matrix with sufficient strength and toughness, its surface properties are critical to the working performance and service life of the prototype. These performance improvements can often get twice the result with half the effort, which is why the surface treatment technology has developed rapidly. Many prototypes did not achieve the expected results in the early stage of processing. If the surface treatment is handled properly, it will also become a good prototype. Let's talk about the surface treatment of the prototype model:

, select the accessories that need surface treatment according to the CMF description chart for classification. For example, those things that need to be plated, those that need to be sprayed, those that need silk screen printing, etc. , are classified according to the requirements.

B, the accessories that need external surface treatment will be outgoing according to the classification. For example, electroplating parts or aluminum alloy oxidation, etc. , it is necessary to send out to a special electroplating manufacturer or oxidation manufacturer. The model manufacturer can't do it. If you need silk screen printing, you need to send out the film file, make the film, and the screen Board. After the screen board is made, you can get back the silk screen.

C, if you need to spray, the special spraying master will paint according to the PT number on the CMF, then spray it directly, and then put it in the oven for a while to cure the paint. The general model manufacturers will have their own full set of spraying equipment, otherwise the business will not be able to do it. In addition to spraying products, additional swatches will be sprayed to facilitate the later production of products to check the color.

D, solid hardware, if you want to do the effect of drawing or blasting the fog surface, the designer needs to provide the sand number, such as coarse sand or fine sand, and it is best to mark it clearly on the CMF file. If there is also a character laser carving, it is necessary to indicate the depth of laser carving.

E, in addition to conventional surface treatment, such as semi-transparent, water transfer, UV transfer, IML, etc. have special surface treatment, the prototype model is difficult to achieve the same effect as the real product. Therefore, it can only look at the effect roughly. If you want to see the perfect effect, you need to open the mold before you can reflect it. The above is where the surface treatment of the prototype model needs attention. After mastering this knowledge, there will be no such confusion when doing surface treatment in the future.
