What Is Acetal and Why Choose It?

Acetal is a strong engineering plastic that works great when you need:

Low friction parts that move smoothly
Components that can resist chemicals
Parts that stay dimensionally stable in wet places
Food-safe and medical-grade components
Wear-resistant gears and bearings

Our CNC prototype machining service can turn this amazing material into almost any shape you need!

Why Choose Istar Machining for Acetal CNC Services?

1. Material Expertise

We know the difference between acetal grades and can help you choose the right one:

Delrin® (homopolymer): Better for mechanical strength and rigidity
POM-C (copolymer): Better chemical resistance and stability
Special grades: FDA-compliant, ESD-safe, UV-stabilized

2. Design Support

Our engineering team helps make your parts better:

Avoid thin walls that might warp
Add proper radii to prevent stress points
Design for optimal machining and cost savings

3. Quality Control

Every part passes strict checks:

Dimensional inspection using advanced CMM equipment
Material verification with proper certifications
Surface finish quality checks

4. Custom Solutions

We can make your acetal parts even better:

Hybrid designs with metal inserts for strength
Special coatings for added wear resistance
Post-machining treatments like annealing

Technical Details About Our Acetal CNC Machining

Getting the perfect acetal part means understanding the material’s properties. Here’s what makes our 5 axis machining process special for acetal:

Impact Strength: We machine parts with Izod impact values of 2.0 ft-lb/in (POM-C) and 1.4 ft-lb/in (Delrin®)
Thermal Stability: Our annealing process at 160°C reduces internal stress for better stability
Surface Finish: We can achieve finishes from Ra 63 µin (as-machined) to Ra 16 µin (polished)

Applications for Acetal Machined Parts

Customers use our acetal parts for many different purposes:

Gears and bearings that need to run smoothly without lubrication
Medical components that must be sterilized repeatedly
Food handling equipment that needs to be safe and clean
Electrical insulators that prevent current flow
Wear plates that help equipment last longer
Snap-fit components that need flexibility and strength
