Board is also known as the first board, which is usually only needed for developing or designing products. The manual board of directors is the first step to verify the feasibility of products. It is the most direct and effective way to find out the defects and deficiencies of the designed products, so as to improve the defect target until the board sample can not be found from the personal hands. At this point, a small amount of pilot production usually needs to find out what is not enough to improve the batch.
According to the materials used in production, the hand board can be divided into plastic hand board, silica gel hand board, metal hand board and oil mud hand board. Plastic hand board: its raw material is plastic, mainly some plastic products, such as television, display, telephone, etc. The design materials of plastic hand board include ABS, PC, PMMA, PU, etc. ABS is the most commonly used design material for handboards; PC and PMMA are transparent parts; Pu is used to produce small batch of silica gel mold products. ABS is machined into blocks, the density of ABS is lower than that of injection molding. After processing, the internal molecular chain is cut and broken. Therefore, the hand board made of ABS has low strength and is easy to break. Products that cannot be used for sale.
The design technology of plastic hand board is numerical control processing and silica gel mold. The other is laser rapid prototyping, very fast. However, due to the poor accuracy of the finished product, the surface quality is not recommended. CNC is CNC milling. There is no difference between this tool and ordinary machining. The difference is that milling materials include ABS, PC, PMMA and other materials. Three dimensional data is programmed by numerical control processing software. Orders output to CNC machine tools can process the semi-finished products we need. Semi finished products are processed by polishing, painting, electroplating and other processes. Equivalent to a formal product. It is the best way to display and verify the appearance and function hand boards.
