Handboard industry materials and material performance (Rapid prototye)

ith the development of industrial society and the continuous improvement of living standards, people's demand for life products and the desire for innovation are also growing day by day.And processing enterprises, mainly satisfied with developed science and technology, growing to create new products, to serve the different areas such as design, development, manufacturing enterprises, for their new product development or improvement of existing products, and design new products, in terms of pattern making, model making give full cooperation and support, to create the value of each other, to achieve a win-win situation.

The products of each enterprise are not the same, and the hand model that needs to be made is also different, so the production materials may also be different:
1, ABS, ABS resin is one of the five synthetic resin, its impact resistance, heat resistance, low temperature resistance, chemical resistance and excellent electrical properties, but also has easy processing and products good size stability, surface gloss, easy painting, coloring, also can undertake surface spraying, electroplating, metal welding, hot pressing and adhesion and other secondary processing, widely used in machinery, automobile, electronic appliances, instruments and meters, textile and construction and other industrial areas, is a very versatile thermoplastic engineering plastics.Because of the performance of ABS, it is also one of the most widely used general plastics in the hand model industry.
2, aluminum alloy: aluminum alloy handboard model is one of the industrial handboard, aluminum alloy to aluminum based alloy general name.The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc.Aluminum alloy density is low, but the strength is relatively high, close to or more than high quality steel, good plasticity, can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the amount of only second to steel.The density of pure aluminum is small (ρ=2.7g/cm3), about 1/3 of that of iron, the melting point is low (660℃), aluminum is a face-centered cubic structure, so it has a very high plasticity (δ:32~40%, ψ:70~90%), easy to process, can be made into a variety of profiles, plates, good corrosion resistance.However, the strength of pure aluminum is very low, and the annealing state σb value is about 8kgf/mm2, so it is not suitable for structural materials.Through long-term production practice and scientific experiments, people gradually to add alloying elements and the use of heat treatment and other methods to strengthen aluminum, which obtained a series of aluminum alloys.The alloy formed by adding certain elements can maintain the advantages of pure aluminum light, but also have high strength, the σb value of 24 ~ 60kgf/mm2 respectively.This makes its "specific strength" (strength and specific gravity of the ratio of σb/ρ) is better than many alloy steel, become an ideal structural material, widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry and other aspects, the aircraft fuselage, skin, compressor often to aluminum alloy manufacturing, in order to reduce the weight.By using aluminum alloy instead of steel plate, the weight of the structure can be reduced by more than 50%.
3.Acrylic: Acrylic, also known as PMMA or plexiglass, from acrylic plastic in English acrylic, chemical name is polymethyl methacrylate.It is an important plasticity polymer material developed earlier, with good transparency, chemical stability and weather resistance, easy dyeing, easy processing, beautiful appearance, and has a wide range of applications in the construction industry.Acrylic with crystal transparency, transmittance in more than 92%, soft light, clear vision, with dye coloring acrylic and have a very good display color effect.Acrylic board also has excellent weather resistance, higher surface hardness and surface gloss, as well as good high temperature performance.Has good processing performance, can be used either thermal molding, can also be used in mechanical processing.Transparent acrylic sheet can be compared with the light transmittance of glass, but the density is only half of glass.In addition, it is not as fragile as glass, and even if broken, it will not form sharp fragments like glass.Its wear resistance and aluminum close, good stability, a variety of chemical corrosion resistance.Good printability and spraying, the use of appropriate printing and spraying process, can give acrylic products ideal surface decoration effect.
4, Stainless Steel: Stainless Steel is short for Stainless acid Steel, resistance to air, steam, water and other weak corrosion medium or Stainless Steel is called Stainless Steel;And will be resistant to chemical corrosion medium (acid, alkali, salt and other chemical etching) corrosion of steel is called acid-resistant steel.Because of the difference in the chemical composition of the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical corrosion, while acid-resistant steel is generally stainless.Stainless steel is not easy to produce corrosion, pitting, rust or wear.Stainless steel or building with metal materials in the highest strength of one of the materials.Because of its excellent corrosion resistance, stainless steel enables structural components to permanently maintain the integrity of the engineering design.The chromium stainless steel is also a combination of mechanical strength and high elongation, easy to manufacture components, can meet the needs of architects and structural designers.
