| Secondary Services | Pad printing, painting, ultrasonic welding, laser marking, sub-assembly |
Precision Assurance
POM parts exhibit significant volumetric shrinkage during crystallization. Our engineering team calculates exact shrinkage compensation factors inside the CAD tooling phase, eliminating sink marks and warping.
Standard Inspection
CMM optical verification, pin-gauge fit checks, and tensile load verification per production batch.
Why Choose POM for Your Application?
POM is a high-performance engineering thermoplastic widely selected for its superior mechanical properties. Often substituting metal components, it is the preferred resin for parts requiring rigidity, natural lubricity, and structural dependability.
Low Friction & Wear
Self-lubricating characteristics ideal for continuous-cycle moving parts, sliding mechanisms, and bushings.
Dimensional Stability
Minimal moisture absorption ensures components maintain exact tolerances across varying humidity and temperatures.
Chemical Resistance
Superior resistance against hydrocarbons, engine fuels, organic solvents, and harsh industrial cleaning agents.
Fatigue Endurance
High resilience against cyclic stresses, impact loads, and vibrations without developing stress cracking.
Key Industry Applications
Our Manufacturing Workflow
We help you move from initial design to certified production through a transparent, engineering-led manufacturing structure.
DFM Review
Rigorous CAD review analyzing gate placement, sink risk, draft angles, and uniform wall thickness.
Tooling
In-house mold fabrication with aluminum for bridge production or P20/NAK80/H13 steel for volume runs.
Resin Selection
Targeting standard, high-impact, or glass-reinforced (GF15/GF25) grades to match performance goals.
Molding & QC
Stable parameter execution and dimensional inspection reports against your critical drawings.
Post-Processing
Secondary services including ultrasonic welding, laser pad printing, packaging, and modular sub-assembly.
