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?

手板模型换个零件加工所用的材料主要分为金属和塑胶，其中金属更常见的就是铝合金和不锈钢这两种，铝合金的密度低，但强度较高，加工性能、优良的焊接特点及电镀性、良好的抗腐蚀性、韧性高及加工后不变形、材料致密无缺陷及易于抛光、上色膜容易、氧化效果等优良特点，经过喷砂氧化处理之后，外观效果会更好。不锈钢耐空气、蒸汽、水等弱腐蚀介质，耐酸、耐碱性能，密度高、耐腐蚀的特性比较好、不易损坏。

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.

塑胶常用的材料有ABS、POM、PMMA、PA、PC、PP、PPS等，其中，ABS是一种工程塑料，在手板行业中比较常用的塑胶材料，抗冲击性、耐热性、耐低温性、耐化学药品性及电气性能优良，还具有易加工、制品尺寸稳定、表面光泽性好等特点，可以拆件加工，可以满足各行业产品的基本要求。

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：又叫赛刚，看这个名字就知道，是一种表面光滑且光泽度较好的硬而致密的材料，弯曲强度、耐疲劳强度，耐磨性都比较好，适合做一些齿轮的零件。PMMA:俗称亚克力，又叫有机玻璃，透明度较好，透明效果比PC材料好，且耐热性优良。PA：又称为尼龙，机械强度高，韧性好，不粘胶水，不建议拆件加工。PC:冲击强度高，尺寸稳定性好，无色透明，着色性好、耐磨性好，可以耐高温，是一种透明材料。

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.
