Established in 1998, now our powder metallurgy factory has a staff of 450,including 8 senior engineers,40 intermediate scientific research personnel. Cover over 40 acres, construction area over 15,000㎡. Our Powder Metallury Factory has the latest producing machines and both chemical and physical testing instrument within national field. Now, our factory owns all kinds of machines for Powder matallurgy parts prodcution, such as pressing, sintering furnace, machining and electric spark for molds about 250 sets, testing machines over 20 sets. We have a large scale producing ability for all kinds of powder metallurgy parts. In the meantime, our factory has built a perfect control system on quality, production, and management.
Factory Manufactures Poweder metal sintered parts for Automobile engine, furniture, agriculture, motors, toolings and so on. Now The PLAGGIO Group. a world famous motorcycle producer has also chosen us as their motorcycle valve guide and valve seat supplier. We are now also the Tier Two of Peugeot of the Pump Gears, Sprockets and Rotor-Stators
The research and development team has rich experience and completed detecting equipment ensure the company to have a strong new produce development capacity. At present, our powder metallurgy products have been broadly applied to many fields like auto, power tools, home appliance, etc..
On the principal of mutual benefits and friendly negotiation, we would like offer warm and completed services for all clients internationally
Manufacture Powder Metallurgy Products
As a professional powder metallurgy parts( sintering parts, sintered parts, powder metal parts) manufacture, our hot selling products are sintering Motorcycle shock Absorber components valve guide and seats, Automobile pump parts shock absorber components, Powder metallurgy sintering gears. But those are not all the parts we are doing now. Every day could comes new powder metallurgy parts from clients all over the world. They are in different structure and different sizes.

Powder Metallurgy Parts Quality Assurance System
With testing machines over 20 sets and two quality checking labs, we insure our powder metallurgy parts’ quality in 6 processes.
- Raw material inspection
- Material composition inspection
- Press -forming inspection
- Physical property inspection
- Dimension inspection
- Final inspection
As a big auto parts factory, we are ISO9001, TS16949, IATF16949 certificated. And PPAP document system applied.
Physical lab to control the precision size and performances
Chemical Lab to analysis the Chemical components
Powder Metallurgy Parts Production System
Our powder metallurgy parts manufactrue usually involves following processes:
Blend Raw Material-Mixing Powder
For iron based powder metal parts, the most component material is “Fe”. But also need many other chemical elements to form a certain iron. So first we need to mix the different chemical elements into full mixture, according to the ingredient by using powder mixing machine.
This step requists highly precision on every elements. If not so, it will affect the quality of the finished iron powder parts.
Pressing to Shape
Put the mixed powder into presses. We have presses from 25-800 tons. Capable of making powder parts from 1 to 18mm. However, not all shapes can be made with this method. Usually types are gear, bushings, bars, squre nuts. If your parts have very complicated structures, we will use MIM method. That’s another types of powder metallurgy.
In the pressing process, engineer will keep checking the density, shape, size of the products. In case of any problem, will need adjust the powder or the machine, die. This is one of the most important steps in manufacturing powder parts.
Sintering the Metal
Sintering the pressed powder parts with ovens. The sintering oven is running automactically. Workers need to put parts into the starting conveyor belt. Then it will run into the oven and stay the process 3-20 hours. Different parts request different time of sintering. Finally, workers collect the sintered powder parts from the conveyor belt too.
Precision Machining or Sizing
Not all the powder parts need this process. Just some parts have special structures, such as screws, grooves, or other shapes can not be pressing in one time. Sometimes a bushing or gear need very precision inner or outside dimension. We need put them into another stamping machine to press again(sizing). we call it “Integer”. Of cause, need mold to do it. If your iron parts not such strict requirement, suggest not necessary to do.
Ultrasonic Cleaning
Ultrasonic cleaning is to clean the dirt engaged in the former steps. It is essential before quality checking.
Quality Checking
Workers will carefully checking the quality after the powder parts come out from the cleaner. We have Physical and chemical testing center for powder material testing. Testing equipment for our iron powder parts include but not limited to Three coordinate detector, Image projector, Pressure testing machine, Carbon sulfur analyzer, OLYMPUS CK51M Optical Microscope.
The Iron Parts will be under the following QC processes.
- Laboratory test analysis
- Metallographic detection analysis
- hardness test
- density measurement
- crush strength test
- surface roughness test
- length measurement and testing
Deburring, Heat Treating and Surface Finishing
Most of the powdered parts need deburring. But only some need Heat Treating, surface coating. If you have hardness requirement, we will send them to heat treating. For powder metallurgy part, suggested surface treatment are blacking and dacromet. We can do the salt spray test for your parts to test the anti-rust performance.
Anti-rust oil immersion
Most of the powder parts need vacuum anti-rust oil immersion to keep the part good.
Quality Checking, Quantity Checking and Packing
This time quality checking will be more on appearance. That will do at the same time with quantity checking and packing.
Storage and Transportation
After packing, send the finished iron powder parts to our storage house and waiting transportation.
