CNC Machined Parts
Custom Machined Plastic Parts
Custom CNC machined plastic parts made from your drawings and CAD files in POM, PEEK, PTFE, nylon and other engineering plastics. For drawing-defined prototypes, one-off parts, low-volume builds and repeat small batches for industrial and engineering applications.
POM / Acetal · PEEK · PTFE · Nylon / PA
Send your 2D drawing or 3D CAD/STEP file with material, quantity and critical requirements for manufacturing review and quotation.
Custom Plastic Components for Engineering Applications
We machine plastic parts to customer drawings for functional prototypes, equipment components, tooling and other engineering applications. Part geometry, material, critical dimensions and quantity are reviewed before production.
Housings & Covers
Machined plastic housings, covers and protective components with mounting and assembly features.
Bushings & Spacers
Custom bushings, sleeves, spacers and locating components manufactured to drawing dimensions.
Mounting & Support Components
Plastic mounting parts, insulators and support components for equipment and assemblies.
Custom Functional Components
Drawing-specific plastic parts with holes, pockets, threads, slots and other machined features.
Engineering Plastics We Machine
We CNC machine engineering plastic components from customer drawings and CAD files. Material selection is typically specified by the customer, and we review the material together with part geometry, tolerances and functional features before manufacturing.
POM / Acetal
Suitable for machined components requiring good dimensional stability, low friction and wear resistance, including bushings, spacers, guides and mechanical components.
PEEK
A high-performance engineering plastic used where temperature resistance, chemical resistance and mechanical performance are important.
PTFE
Used for components requiring low friction and chemical resistance. Machining requirements should consider the material's relative softness and dimensional behavior.
Nylon / PA
Used for functional mechanical components where wear resistance and toughness are required. Material grade and moisture-related dimensional requirements should be considered for precision parts.

What We Review Before Machining Your Plastic Parts
Engineering plastics behave differently during machining. Material properties, part geometry and critical dimensions are reviewed together before production to identify features that may affect dimensional stability, deformation or assembly.
Dimensional Stability
Plastic parts can respond differently to machining, temperature and material condition. Critical dimensions and mating features should be clearly identified on the drawing so they can be reviewed before production.
Thin Walls & Deformation
Thin sections, large flat areas and slender features may be more sensitive to clamping and machining stress. These features are reviewed before manufacturing when they could affect final part geometry.
Holes, Threads & Mating Features
Threaded holes, bores, locating features and mating surfaces are reviewed according to the selected plastic and the functional requirements shown on the drawing.
Material-Specific Behavior
POM, PEEK, PTFE and nylon do not behave the same during machining. Material characteristics are considered together with geometry, tolerances and functional requirements during manufacturing review.
From Your Drawing to a Checked Finished Part
Your drawing, material and critical requirements are reviewed before production. Finished parts are checked against the agreed requirements before shipment.
Drawing & CAD Review
We review the supplied 2D drawing and 3D CAD/STEP files to understand part geometry, material, critical features and manufacturing requirements before production.
Material & Requirement Confirmation
Material grade, quantity, tolerances, threads, mating features and relevant appearance requirements are confirmed as part of the manufacturing review.
Dimensional Inspection
Critical dimensions and functional features are checked using appropriate inspection tools according to the part and drawing requirements.
Final Part Check
Parts are visually checked for machining condition, burrs and relevant appearance requirements before packing and shipment.
Support from Initial Parts to Repeat Production
We support initial parts for fit, function and design validation, followed by low-volume or repeat production after the design is confirmed. If the design changes between builds, send the latest drawing or CAD revision for review before production.
What to Send for a Machined Plastic Parts Quote
Have a plastic part ready for manufacturing? Send your drawing or CAD file together with the basic project requirements below. This helps us review the part, identify manufacturing considerations and prepare a more useful quotation.
Drawing or CAD File
Send your 2D drawing and/or 3D CAD file such as STEP/STP.
Material
Specify the required plastic material and grade where known.
Quantity
Include the quantity required for the current build and, where relevant, expected repeat quantities.
Critical Dimensions & Tolerances
Identify critical dimensions, fits and tolerance requirements on the drawing whenever possible.
Functional Requirements
Highlight threads, mating features, inserts or other features important to assembly or part function.
Appearance & Special Requirements
Include relevant requirements for burrs, edges, surface condition, appearance or other project-specific expectations.
Required Timing
Let us know your required delivery date or project schedule if timing is critical.
Questions Before Requesting a Quote
What engineering plastics can you machine?
We machine engineering plastics including POM/Acetal, PEEK, PTFE and Nylon/PA. If your drawing specifies another plastic material or grade, send the material specification with your RFQ so we can review it for the project.
Can you support both prototypes and repeat production?
Yes. We can support initial parts for engineering validation as well as low-volume and repeat builds after the design is confirmed. For revised parts, please provide the latest drawing or CAD revision before production.
What tolerances can you hold on machined plastic parts?
Achievable tolerances depend on the plastic material, part size, geometry and critical features. Please identify important dimensions and fits on your drawing so they can be reviewed before quotation.
Can you machine threads, holes and assembly features in plastic parts?
Yes, depending on the material and part design. Threads, bores, mounting holes, pockets and other functional features can be reviewed from your drawing before manufacturing.
Have a Plastic Part Ready for Manufacturing?
Send your 2D drawing or 3D CAD/STEP file together with the material, quantity and project requirements. We’ll review the information for manufacturing and quotation.
