SLA-Stereo Lithography Appearance technology, using photosensitive resin 3-D printing materials: milky white texture, good strength, but relatively small toughness, small and thin brittle fracture, but easy to grind, electroplating, painting and coloring. Photosensitive resin is composed of two parts, namely photoinitiator and resin (resin consists of prepolymer, diluent and a small amount of additives). The amount of photoinitiator and diluent has an important influence on the curing speed and quality of photosensitive resin. When the proportion of photoinitiator and diluent is appropriate, not only the curing speed is fast, but also the curing quality is good. Therefore, in order to select large brand manufacturers, mature and stable photosensitive resin 3D Printing materials are very important. In terms of performance, there are also some imported photosensitive resin materials with high strength, transparency, high temperature resistance, moisture resistance and waterproof functions. In addition, three-dimensional printing materials of composite ceramics, such as alumina (AI2O3) m zirconia (ZRO2), hydroxyapatite (HAP), tricalcium phosphate (TCP) and so on, which are similar to high-resolution ceramic powder and photosensitive resin, can be selected.
SLS-Selective Laser Sintering technology, using 3D printing materials: PA Series Nylon 3D Printing Material: Abrasion Resistance, High Strength and Stiffness, Good Chemical Resistance, Excellent Long-term Invariant Behavior, High Selectivity and Detailed Analysis, Biocompatibility in accordance with EN ISO 10993-1 and USP, and in accordance with EU Plastics Directive approved for food contact. Typical applications of this material are the highest quality of fully functional plastic parts. But the surface is relatively rough. There are also PA3200GF nylon fiberglass materials for deep drawing dies or any other applications requiring specific stiffness, high thermal deformation temperature and low wear; typically used in aluminium-filled nylon materials for metallic appearance and thermal load parts. At present, desktop LS laser sintering PA12 nylon powder material is also an option.
SLM Selective Laser Melting technology,Under the irradiation of high density laser energy, metal powders can be completely melted. After cooling, they can be shaped and welded. It is through this process that SLM technology forms the 3d model layer by layer.SLM technology can print stainless steel, die steel, cobalt chromium alloy, titanium alloy, aluminum alloy, copper alloy, nickel base alloy powder, etc.It can print metal parts with complex structure to help shorten product development cycle and reduce R & D cost.

Hot sale train brake shoe
Rail hot sale train brake shoe consists of two parts, the cast iron support and the composite body. Both the surface and core of the Trail composite brake shoe have the hardness within the range of 197< HB< 255. Our trail composite brake shoe enjoys many advantages including hardness, impact strength and so on.
When facing subsequent impacts to the brake block or brake shoe, the steel support must remain intact.
