Sints Precision Technology Co., Ltd was established in 1995, which is a manufacturer of Metal Injection Molding Products, Powder Metallurgy Parts and precision metal parts that other conventional processing produce. Sints has achieved a leadership position in the field of precision parts, providing excellent custom fabrication service to customers in more than thirty countries in the Americas, Europe and Asia.
1995 ● Rong Li Powder Metallurgy Factory was established.
1997 ● Recognized into SINTS Powder Metallurgy Product Factory
2000 ● Passed ISO9001:2000 quality management system
2005 ● Established MIM production workshop
2009 ● Zhongshan Sints Powder Metallurgy Co, . Ltd established, and become a qualified supplier of GE.
MIM and PM
MIM, PM that Sints uses as the core manufacturing technologies are best suited for precision metal parts with complex geometry, tight tolerance, light weight, high density, good hardness and special performance, such as car door lock parts, safe lock parts, electronic parts for electric lock, car parts, sintered gears and so forth.
Metal Injection Molding combines the design flexibility of plastic injection molding with the strength and durability of metal to offer cost effective solutions for metal parts with highly complex geometries.
Powder Metallurgy is an additional forte, wherein Sints has been supplying Poweder metallurgy products, sometimes referred to as powder metal sintered parts, in a wide variety of pre-alloyed metal powders and combinations of elemental metal powders for many industries.

Metal Injection Molding Technology
MIM is an advanced metal forming technology that use injection molding machine to manufacturing precision and complex metal parts, which combines the advantage of PM and plastic injection molding.
Powder injection shape technical characteristics
MIM as a manufacturing quality precision components near net shape technology, and the processing methods compared with conventional superiority. MIM can create many of the complex shape of the parts : such as external cutting shafts, the thread, taper, surface, cross-boundary Kong, blind Kong, Taiwan and four key sales, strengthen tendons boards, and so on the surface roll-with the above characteristics are not parts with conventional powder metallurgy methods. Since the adoption of MIM almost no longer manufactured parts for machines processing, reduce material consumption, resulting in the production of complex shape parts for more than a certain number of values, MIM will be more economical than aircraft processing methods.

Powder Metallurgy Technology
Powder metallurgy (PM), sometimes referred to as powdered metal sintering, is a process for manufacturing metal parts by heating compacted metal powders just below their melting points. In other words, PM is a metal shaping process that creates near-net parts from powdered metal. Sometimes, the products, manufactured by PM, are known as sintered products.
