How to choose the processing data of hand plate model? Many professions in the development of new products, we must do hand model to verify the feasibility of the product, check the design of the product whether there are shortcomings, deficiencies, disadvantages, so as to improve the shortcomings, improve the product details. There are CNC processing, 3d printing and silicone membrane processing methods for the hand model. The conventional hand model generally uses ABS engineering plastics, which are easy to process and good-looking after processing during production. High temperature resistant hand model, can choose epoxy resin, bakelite, black pc, nylon (PA), epoxy resin is not bonded, the need for all processing. Wear resistant hand model, nylon (PA) or polypropylene (PP) available. Tongming hand plate model, can choose acrylic (PMMA), Tongming ABS, Tongming PC and other materials. Processed hand plate model, through polishing and polishing after processing, the clarity is very high, to achieve the same role as the real product. The surface post treatment of hand plate model is generally divided into: grinding, frosting, oil injection, electroplating and screen printing and other appearance effects. Hand model spray can spray smooth surface, matte surface, sand surface, semi-bright, bright color, fluorescent color, rubber oil and so on.
