The hand board is also called the first board, rapid prototyping, etc. it means that the designer does not need to open the mold after completing the design, but the manufacturer of the hand board model makes several identical samples to check the appearance and practicability according to the product appearance or structural drawings. How is the hand board model made, and what are the steps of its process flow?
There are many processes for hand model, including CNC processing, vacuum coating, 3D printing, surface treatment and so on. CNC processing can produce more accurate product samples. The main materials used are aluminum alloy, plastic plate and so on. Plastic plate, bakelite and aluminum alloy are generally used to make hand board models. Vacuum coating refers to the re engraving of the sample plate, which can process more products by opening the silica gel mold with samples. Produce small batch of product samples, or change them into materials that meet certain special requirements. Surface treatment, including painting, polishing, silk screen printing and electroplating, etc. The purpose of surface treatment is to make the sample realize various surface effects in the effect drawing and make the hand model closer to the injection molded product.
