Tianjin SWKS Technology & Development Co.,Ltd is one of the most reliable manufacturers and suppliers of custom pom gears and precision mechanical plastic parts in China. If you're going to buy bulk cheap custom pom gears and precision mechanical plastic parts, welcome to get quotation from our factory. Quality products and low price are available.
SWKS manufactures custom POM gears and precision mechanical plastic components for industrial equipment, automation systems, conveyors and machinery.
POM, also known as acetal, is widely used for moving and load-bearing plastic components because of its low friction, good wear resistance, dimensional stability and mechanical strength.
We support both injection molding and CNC machining, allowing the production method to be selected according to the part geometry, required quantity, tolerance and project stage.
Typical POM Parts We Manufacture
Custom POM components can include:
Spur gears and pinion gears
Plastic rollers
Bushings and sleeves
Guide blocks
Wear plates
Sliding components
Conveyor components
Mechanical spacers
Precision molded components
Custom machine replacement parts
All parts are manufactured according to customer drawings, 3D files or physical samples.
Material Options
Material: POM / Acetal
Available options may include:
POM-H
POM-C
Standard natural POM
Black POM
Reinforced or modified POM grades
Antistatic or conductive grades for special applications
Material selection should be based on operating temperature, mechanical load, friction, chemical exposure and dimensional requirements.

Injection Molding or CNC Machining?
The most suitable production process depends mainly on quantity and geometry.
CNC Machining
CNC machining is often suitable for:
Prototype quantities
Small production runs
Parts with complex machining features
Projects that do not justify mold investment
Early-stage design verification
Injection Molding
Injection molding is generally more suitable for:
Medium and high-volume production
Stable repeat orders
Components requiring consistent geometry
Projects where lower unit cost is important
For new projects, our team can review your drawing and help determine whether CNC machining or injection molding is more appropriate.
Customization Capabilities
We manufacture parts according to project-specific requirements rather than fixed catalog dimensions.
Customization may include:
Dimensions: According to 2D or 3D drawing
Color: Natural, black or customized
Process: Injection molding / CNC machining
Drawing formats: STEP, STP, IGS, DWG, PDF and other common formats
Production: Prototype, low-volume and mass production
Inspection: Dimensional and visual inspection according to drawing requirements
Tolerance capability depends on part size, geometry, material and production process.
Applications
