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.

手板依照制作常用的材料，可分成塑胶手板、硅胶手板、金属手板、油垢手板。塑胶手板：其原料为塑胶，主要是一些塑胶产品的手板，例如电视、显示屏、话机这些。塑胶手板设计材料有ABS、PC、PMMA、PU等几类。ABS是经常使用的手板设计的材料;PC、PMMA为制作全透明零件用;PU为硅胶模小批量生产商品制作用材料。ABS是体制成小块，相对密度较注塑出的ABS低。其通过加工后，內部分子结构链被激光切割破裂。因此用ABS做成的手板抗压强度低，易破裂。不能作为销售用的商品。

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.

塑胶手板设计工艺为CNC数控加工和硅胶模。也有一种叫激光器迅速成型，制作速度更快。但因其制成品精密度差，表层质量欠佳而不强烈选用。CNC即数控铣削加工。常用数控刀片与一般机械加工制造沒有差别。所不一样的是其切削的材料为ABS、PC、PMMA等材料。三维数据通过数控加工软件编程。导出到CNC机订就可以加工出大家所必须的半成品加工。半成品通过打磨抛光、喷涂、电镀工艺等工艺进行后试品。可与宣布商品相媲美。是外观手板及作用手板展示及认证的方式。

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.
