OEM Powder Metal Sintered Metal Machined Small Worm Gear Parts

  • 1, Material:stainless steel/alloy/iron/brass
  • 2, Processing:metal injection molding
  • 3, Good quality, high precision
  • 4, Competitive price

  • MIM (Metal Injection Molding) combines the technologies of thermoplastic injection molding and powder metallurgy to produce complex-shaped, high density, high performance metal parts. 

    Not only the external dimension tolerance but internal dimension tolerance will be guaranteed. An internal helical gear is one of the examples. 


    These gears were traditionally only possible by machining or by special dedicated machine, which is not able to produce small size gears and this is the reason the customer use plastic gears.


    However, MIM realises the mass production of such small special gears,  and now it is commonly employed for such gears mass production.

     

    1. Best applied to small parts (typically less than 100 grams)

    2. Offers lower cost solution

    3. Improved mechanical properties

     How MIM Works

    The MIM process combines the design flexibility of plastic injection molding with the strength and integrity of wronght metals to offer cost effective solutions for highly complex part geometries.

    The MIM process is typically explained as four unique processing steps (compounding, molding, debinding and sintering) to produce a final part that may or may not need final finishing operations

    With an X-ray CT device, it is possible to obtain complete 3-dimensional measurement data, including the inside of the gear. 


    This inspection and evaluation system is indispensable for providing customers with MIM that is even finer, more precise, and of higher quality.


    There are many things that can be achieved in microgear production with this system, but the first is that it enables a higher level of quality assurance. 


    Besides pitch error, tooth thickness, tooth type / tooth muscle error, tooth surface error, etc.,grade evaluation (corresponding to JIS) for micro gears of rice grain size or smaller is also possible.

     

    Our cutting-edge quality control assurance system supports our micro gear quality in time, non-destructively. Any certifications of gear standard will be provided with our component by request. 


     If you have any micro gear design given up for the serial production as they're difficult to produce with other manufacturing methods, please contact us with the drawings.
