Handboard models and parts processing are the most common in the industrial market and a necessary process for product development. Only when the handboard is ready can batch production be carried out, which can help enterprises reduce research and development costs and risks, and quickly seize the market. What materials should be used to make the newly designed prototype to meet the designer's requirements?

手板模型換個零件加工所用的材料主要分為金屬和塑膠，其中金屬更常見的就是鋁合金和不銹鋼這兩種，鋁合金的密度低，但強(qiáng)度較高，加工性能、優(yōu)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(yōu)良特點，經(jīng)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(zhì)，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 processing the replacement parts of the hand board model are mainly divided into metal and plastic. The most common types of metal are aluminum alloy and stainless steel. Aluminum alloy has low density but high strength, excellent processing performance, excellent welding and electroplating properties, good corrosion resistance, high toughness, and no deformation after processing, dense and defect free materials, easy polishing, easy coloring film, and excellent oxidation effect, After sandblasting and oxidation treatment, the appearance effect will be better. Stainless steel is resistant to weak corrosive media such as air, steam, and water, with acid and alkali resistance, high density, good corrosion resistance, and is not easily 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(yè)中比較常用的塑膠材料，抗沖擊性、耐熱性、耐低溫性、耐化學(xué)藥品性及電氣性能優(yōu)良，還具有易加工、制品尺寸穩(wěn)定、表面光澤性好等特點，可以拆件加工，可以滿足各行業(yè)產(chǎn)品的基本要求。

The commonly used materials for plastics include ABS, POM, PMMA, PA, PC, PP, PPS, etc. Among them, ABS is an engineering plastic that 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 characteristics such as easy processing, stable product size, and good surface gloss. It can be disassembled for processing and 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(qiáng)度、耐疲勞強(qiáng)度，耐磨性都比較好，適合做一些齒輪的零件。PMMA:俗稱亞克力，又叫有機(jī)玻璃，透明度較好，透明效果比PC材料好，且耐熱性優(yōu)良。PA：又稱為尼龍，機(jī)械強(qiáng)度高，韌性好，不粘膠水，不建議拆件加工。PC:沖擊強(qiáng)度高，尺寸穩(wěn)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。

POM: Also known as Saigang, it is a hard and dense material with a smooth surface and good glossiness. It has good bending strength, fatigue resistance, and wear resistance, making it suitable for making gear parts. PMMA: Commonly known as acrylic, also known as organic glass, has good transparency, better transparency than PC materials, and excellent heat resistance. PA: Also known as nylon, it has high mechanical strength, good toughness, and does not adhere to adhesive. It is not recommended to disassemble parts for processing. PC: High impact strength, good dimensional stability, colorless and transparent, good coloring and wear resistance, can withstand high temperatures, and is a transparent material.
