Material advantages
Why engineers choose POM for precision parts
POM (Polyoxymethylene), also known as Acetal or Delrin, is a strong engineering thermoplastic for moving components where metal may be too heavy or vulnerable to corrosion.
Dimensional stability
Holds its shape across changing humidity and temperature conditions—important for gear teeth and interlocking mechanisms.
Low friction and wear
Natural lubricity suits sliders, bearings, and bushings, and can reduce the need for external lubricants.
Excellent machinability
CNC milling and turning support tight-tolerance features and complex geometries in precision plastic components.
Strength under repeated use
High stiffness and fatigue resistance help parts withstand repetitive mechanical stress.
Machining capabilities

Production planning
CNC machining or injection molding?
The right route depends on your part geometry, annual volume, and where the design sits in its lifecycle. Our 10 manufacturing engineers perform a DFM review with every RFQ to help you assess the trade-offs.
Keep machining
Flexible for evolving designs
CNC is often a practical choice for prototypes and low-to-medium volumes. We can optimize toolpaths to reduce cycle times and unit costs as the design develops.
Evaluate molding
Assess the volume crossover
When annual volume exceeds roughly 1,000–2,000 units, we can compare upfront tooling investment with a potentially lower per-part cost.
A project-specific recommendation
There is no one-size-fits-all crossover point. We consider part geometry, annual demand, design maturity, material requirements, tooling expenditure, and expected per-part cost before recommending a route. This helps you avoid committing to a mold before the design or demand is ready.
Quality and delivery
One coordinated process, from stock to shipment
We manage the production process so you do not have to coordinate multiple vendors across China.
-
01
Traceable material
We verify high-quality, traceable POM stock for each batch.
-
02
Process oversight
Machining is monitored against the requirements for your gears, sliders, and other precision features.
-
03
Final inspection
Dimensions and surface quality are checked against your drawings before shipment.
-
04
Logistics coordination
International shipping is coordinated to support dependable delivery schedules.
Engineering support
Improve manufacturability without losing function
We do more than machine to print. If thin walls or sharp internal corners could make a POM part prone to warping, our engineers can suggest design modifications that preserve function and improve manufacturability.
For robotics, automation equipment, and scientific instruments, we also look for ways to reduce secondary operations and optimize BOM cost.
Useful RFQ inputs
