Precision Powder Metallurgy Small Metal Pinion Gear for Mechanical Parts

MIM is a new kind of metal parts and components forming modern powder 
injection molding technology to introduce the field of powder metallurgy. 
It is a high-tech in the field of powder metallurgy and industry. MIM process 
steps are: first select the MIM-compliant metal powder and organic binder in 
a certain temperature conditions using the appropriate method of mixing into
a uniform feeding, and then after granulation in the plasticized plastic 
injection molding machine Into the mold cavity to obtain the forming billet, 
and then by chemical or solvent extraction method degreasing treatment, 
and finally by sintering densification to get the final product.
                                           MIM product features:  
                                           1, parts of the geometric shape of the high degree of freedom, like the 
                                              production of plastic products, like the formation of a complex shape 
                                              of the metal parts;      
                                           2, MIM product density uniformity, good finish, surface roughness can
                                              reach Ra 0.80 ~ 1.6μm, weight range of 0.1 ~ 200g. High dimensional
                                              accuracy (± 0.1% to ± 0.3%), generally without subsequent processing;      
                                           3, wide application of a wide range of materials, wide application areas,
                                              high utilization of raw materials, a high degree of automation, process
                                              is simple, can achieve continuous mass production;       
                                           4, product quality and reliable performance, the relative density of products 
                                               up to 95% to 99%, can be carburizing, quenching, tempering and other 
                                               heat treatment. Product strength, hardness, elongation and other mechanical
                                               properties, wear resistance, fatigue, uniform organization; It is widely                                                    believed
                                               that the development of MIM technology will lead to a revolution in parts 
                                               forming and processing technology, known as "the most popular
                                               parts of the 21st century  forming technology."
