Comprehensive Guide: Delrin (Acetal POM) CNC Machining Cost Estimator
Delrin (Polyoxymethylene / Acetal) is the primary engineering plastic for low-friction gears, bushings, and insulating manifolds due to its high dimensional stability and clean chip breaking.
Mathematical Formula Breakdown
Unit Cost = (Delrin Stock Mass × $/kg) + [(Machining Mins / 60) × Machine $/hr] + Tooling Wear + Setup Allocation.
Industry Pricing Benchmarks
Delrin POM bar stock costs $11.00–$15.00/kg. Machine rates for plastic CNC milling range from $60 to $85/hr.
Optimization Strategies
- Use razor-sharp single-flute carbide routers to eliminate burrs and thermal plastic melting.
- Store Delrin stock at ambient room temperature 24 hours prior to machining to ensure tight tolerances.
Frequently Asked Questions
Is Delrin easy to machine on a CNC mill?
Yes! It has excellent chip breaking properties, low cutting resistance, and requires minimal coolant.
