Handboards, also known as first boards, are usually required for products that have just been developed or designed. Handboards are a step in the feasibility analysis of certified products. They are an immediate and reasonable method to identify the shortcomings, deficiencies, and shortcomings of product design, and then systematically improve the shortcomings until they cannot be found from certain samples. At this point, it is usually necessary to conduct small-scale trial production in order to identify areas in the batch that cannot be improved.
The hand board can be divided into plastic hand board, silicone hand board, metal hand board, and oil stain hand board according to the commonly used materials for production. Plastic hand board: Its raw material is plastic, mainly used for some plastic product hand boards, such as televisions, display screens, and telephones. There are several types of plastic hand board design materials, such as ABS, PC, PMMA, PU, etc. ABS is a commonly used material for hand board design; PC and PMMA are used for making fully transparent parts; PU is a material used for small-scale production of goods using silicone molds. ABS is made into small pieces, with a lower relative density than ABS produced by injection molding. After processing, the internal molecular structure chains are cut and broken by laser. Therefore, hand boards made of ABS have low compressive strength and are prone to cracking. Goods that cannot be used for sales.
The design process of the plastic hand board is CNC machining and silicone mold. There is also a method called laser rapid prototyping, which produces faster production speed. However, due to its poor precision and poor surface quality, it is not strongly recommended for use. CNC refers to CNC milling processing. There is no difference between commonly used CNC blades and general mechanical manufacturing. The difference is that the materials it cuts are ABS, PC, PMMA, and other materials. 3D data is programmed through CNC machining software. Exporting to CNC machine can process the necessary semi-finished products for everyone. The semi-finished product is subjected to post testing through processes such as polishing, spraying, and electroplating. Can be comparable to the announced product. It is a way of displaying and certifying the appearance and function of the hand board.
