182. Molded metal powder coated after laser treatment process?

1. First with dilute sodium carbonate solution grease cleaning the surface of the metal powder, and then clean the surface oxide diluted hydrochloric acid, washed with water, and finally with a wetting agent for surface treatment
2. Coating solution preparation. Will increase slip agents, mold release agents, wetting and dispersing agents, hot melt adhesives with different melting points by a certain percentage dissolved in a solution of halogenated hydrocarbons in the heated
3. The coating solution and surface treatment of metallic powder by a certain percentage in the double cone rotary vacuum dryer mixed, drying, solvent recovery
4. The coated metal powder in the ball mill for grinding processing, screening the powder to a certain size
5. In the processed powder powder nano powder reduce viscosity and improve the powder flowability, are coated for selective laser sintering of metal powder (CMP1)

Rapid prototyping method is fast making mold technology called rapid tooling, rapid prototyping technology can not only adapt to a variety of production types, especially single and small quantities of mold, and can adapt to the complexity of the mold manufacturing.
