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，可分成塑膠手板、硅膠手板、金屬手板、油垢手板。塑膠手板：其原料為塑膠，主要是一些塑膠產品的手板，例如電視、顯示屏、話機這些。塑膠手板設計材料有ABS、PC、PMMA、PU等幾類。ABS是經常使用的手板設計的材料;PC、PMMA為制作全透明零件用;PU為硅膠模小批量生產商品制作用材料。ABS是體制成小塊，相對密度較注塑出的ABS低。其通過加工后，內部分子結構鏈被激光切割破裂。因此用ABS做成的手板抗壓強度低，易破裂。不能作為銷售用的商品。

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.

塑膠手板設計工藝為CNC數控加工和硅膠模。也有一種叫激光器迅速成型，制作速度更快。但因其制成品精密度差，表層質量欠佳而不強烈選用。CNC即數控銑削加工。常用數控刀片與一般機械加工制造沒有差別。所不一樣的是其切削的材料為ABS、PC、PMMA等材料。三維數據通過數控加工軟件編程。導出到CNC機訂就可以加工出大家所必須的半成品加工。半成品通過打磨拋光、噴涂、電鍍工藝等工藝進行后試品?？膳c宣布商品相媲美。是外觀手板及作用手板展示及認證的方式。

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.
