Handboard model and parts processing are common in the industrial market, and they are also a certain process of product R & D. only when the handboard is done well can batch production be carried out, which can help enterprises reduce R & D costs and risks and quickly seize the market. What materials should be used to make the newly designed hand board model to meet the designer's requirements? We list some commonly used hand model making materials, analyze their characteristics, and you can easily know what kind of materials you need.

手板模型換個零件加工所用的材料主要分為金屬和塑膠，其中金屬常見的就是鋁合金和不銹鋼這兩種，鋁合金的密度低，但強度較高，加工性能、優良的焊接特點及電鍍性、良好的抗腐蝕性、韌性高及加工后不變形、材料致密無缺陷及易于拋光、上色膜容易、氧化效果等優良特點，經過噴砂氧化處理之后，外觀效果會更好。不銹鋼耐空氣、蒸汽、水等弱腐蝕介質，耐酸、耐堿性能，密度高、耐腐蝕的特性比較好、不易損壞。

The materials used for the processing of another part of the hand model are mainly divided into metal and plastic. The common metals are aluminum alloy and stainless steel. Aluminum alloy has low density but high strength, processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy polishing, and easy coloring film Oxidation effect and other excellent characteristics, after sand blasting oxidation treatment, the appearance effect will be better. Stainless steel is resistant to weak corrosive media such as air, steam and water, acid and alkali resistance, high density, good corrosion resistance and not easy to be damaged.

塑膠常用的材料有ABS、POM、PMMA、PA、PC、PP、PPS等，其中，ABS是一種工程塑料，在手板行業中比較常用的塑膠材料，抗沖擊性、耐熱性、耐低溫性、耐化學藥品性及電氣性能優良，還具有易加工、制品尺寸穩定、表面光澤性好等特點，可以拆件加工，可以滿足各行業產品的基本要求。

Common plastic materials include ABS, POM, PMMA, PA, PC, PP, PPS, etc. among them, ABS is an engineering plastic, which is commonly used in the hand board industry. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size, good surface gloss and can be disassembled for processing, It can meet the basic requirements of products in various industries.

POM：又叫賽剛，看這個名字就知道，是一種表面光滑且光澤度較好的硬而致密的材料，彎曲強度、耐疲勞強度，耐磨性都比較好，適合做一些齒輪的零件。

POM: also known as saigang, it is a hard and dense material with smooth surface and good gloss. It has good bending strength, fatigue strength and wear resistance. It is suitable for some gear parts.

PMMA:俗稱亞克力，又叫有機玻璃，透明度較好，透明效果比PC材料好，且耐熱性優良。

PMMA: commonly known as acrylic, also known as plexiglass, it has good transparency, better transparency effect than PC material, and excellent heat resistance.

PA：又稱為尼龍，機械強度高，韌性好，不粘膠水，不建議拆件加工。PC:沖擊強度高，尺寸穩定性好，無色透明，著色性好、耐磨性好，可以耐高溫，是一種透明材料。PP:聚丙烯，密度小，強度剛硬，硬度耐熱性均優于低壓聚乙烯，可在溫度100°左右使用。

PA: also known as nylon, it has high mechanical strength and good toughness. It does not stick glue. It is not recommended to disassemble parts for processing. PC: it has high impact strength, good dimensional stability, colorless and transparent, good coloring and wear resistance, and can withstand high temperature. It is a transparent material. PP: polypropylene, with small density, rigid strength, hardness and heat resistance, is better than low-pressure polyethylene, and can be used at a temperature of about 100 °.
