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