Plastic Milled Parts Made to Order
Milled parts in POM, PA, PEEK, PE-UHMW and PTFE made to drawing. We review your enquiry and place it with a vetted partner shop. Milled dry, without coolant, from 1 piece.
What Sets Plastic Milled Parts Apart
Light weight, chemical resistance and electrical insulation make engineering plastics indispensable in many industries. Our partner shops mill plastic dry, without coolant and without contamination.
Parts are milled from STEP files, DXF drawings or PDF. Sharp single-flute cutters and adapted feeds prevent melting and burrs. We place your part with a shop that machines plastic regularly.
Plastics for CNC Milled Parts
Our partner shops mill all common engineering and high-performance plastics. The choice of material depends on temperature resistance, wear and approvals.
POM (Polyoxymethylene)
The classic for milled parts: Highest stiffness among thermoplastics, low moisture absorption, excellent machinability. For gears, bearings, guides.
PA 6 / PA 66 (Polyamide)
Tough, wear-resistant and vibration-damping. For bushings, guide rollers and housings. PA absorbs moisture and should be stored dry before milling.
PEEK (Polyetheretherketone)
High-performance plastic up to 250°C continuous temperature. FDA and biocompatible. For medical, aerospace and chemical industries.
PE-UHMW
Ultra-high molecular weight polyethylene: Extremely wear-resistant, self-lubricating, food-safe (FDA). For slide rails, chain guides and transport.
PTFE (Teflon)
Chemically inert, lowest friction coefficient of all plastics (µ = 0.04). For seals, bearings and chemical apparatus.
PVC / PVDF
Chemically resistant, weldable, cost-effective. PVDF for aggressive media (acids, alkalis). For pipe fittings, valves and tank parts.
Benefits of Plastic Milled Parts
Dry Machining
Plastic milled parts are machined without coolant. No cleaning, no contamination, ideal for medical and food technology.
Lightweight
Engineering plastics weigh only 1/5 to 1/7 of steel. Weight savings up to 85% with comparable function.
Chemical Resistance
PTFE, PVDF and PEEK resist acids, alkalis and solvents. No corrosion protection needed.
Electrical Insulation
Plastic milled parts insulate electrically and thermally. For PCB holders, insulation flanges and test fixtures.
Burr-Free Surfaces
Single-flute cutters and suitable cutting parameters give plastic milled parts clean, burr-free edges.
No Post-Cleaning
Because the parts are machined dry, no cleaning is needed. Plastic milled parts come off the machine ready to install.
Your Plastic Milled Part in 5 Steps
Send Inquiry
Send drawing or 3D model (STEP, DXF, PDF) with desired plastic and quantity.
Review & Placement
Specialists from our team check the drawing and the choice of plastic. Within 24 hours we get back to you with the right partner shop.
Quote & Approval
The partner shop prepares the quote with unit price and delivery date. After your approval it sources the stock (plates, blocks or round bars).
Dry CNC Milling
The partner shop mills dry with plastic-specific tools and inspects the dimensions.
Delivery
The partner delivers directly to you: inspected, burr-free, ready to install without cleaning.
Precision for Plastic Milled Parts
Dimensional Tolerances from IT7
Tighter tolerances than IT7 are possible with plastics, but require adjustment for the material's spring-back behavior.
Surfaces to Ra 0.8
Plastics deliver good surfaces directly from the mill. Ra 0.4 achievable with polished tool edges.
Dimensional Stability
Adapted clamping and low cutting forces keep distortion small, even on thin-walled plastic parts.
Threads in Plastic
Metric threads, thread inserts (Helicoil) and press-in fittings. For soft plastics we recommend threaded bushings.
Typical machines for Plastic Milled Parts
Machining centre
Machining centre with 3 to 5 axes for plastic plates, housings and 3D freeform parts. With a 5th axis several sides are machined in one setup.

Questions about Plastic Milled Parts
Q1Which plastics can be CNC milled?
All machinable engineering plastics: POM, PA 6/66, PEEK, PE-UHMW, PTFE, PVC, PVDF, PC, PMMA (acrylic) and fiber composites (GRP/CFRP). Material selection depends on temperature, chemical resistance and mechanical requirements.
Q2What do plastic milled parts cost?
Plastic milled parts are generally cheaper than metal parts, as cycle times are shorter and no coolant is needed. Simple POM parts from approx. €15, 40/piece (single part), PEEK parts from approx. €50, 150. Unit costs drop significantly in small series.
Q3Why is plastic dry-milled?
Coolant can attack plastic, make it swell or contaminate it. Dry machining prevents this. With PEEK and PA the low thermal conductivity is the challenge. Optimised cutting parameters and sharp single-flute cutters solve it.
Q4Can PEEK milled parts be manufactured?
Yes. PEEK machines well but needs tools with positive cutting geometry and adapted feeds. Our partner shops mill PEEK parts for medical technology, aerospace and the chemical industry.
Q5Are plastic milled parts food-safe?
Yes, PE-UHMW and POM are available in FDA-compliant, food-grade types (EU 10/2011). For other plastics we advise on material choice. Because the parts are milled dry, no coolant residue remains on them.
Q6What tolerances are possible for plastic milled parts?
Tolerances from IT7 are reproducibly achievable. Tighter tolerances have to account for springback and thermal expansion of the plastic. When reviewing your drawing we advise you on economically sensible tolerancing.
Q7Can threads be cut in plastic?
Yes, metric threads work excellently in POM and PA. For softer plastics (PE, PTFE), we recommend thread inserts (Helicoil) or pressed-in metal bushings for durable screw connections.
Q8From what quantity can I request plastic milled parts?
From 1 piece. Our partner shops mill prototypes, one-off parts and series. For very large quantities injection moulding may be more economical, we raise this when reviewing your enquiry.
