CNC machining from our in-house production
CNC-milled plastic parts made to drawings
Bespoke contours, cut-outs, holes and recesses: our CNC milling service produces your plastic components from drawings or CAD data – from individual parts and prototypes to series production.
We supply both the material and the machining. Send us your component data and requirements; we will assess production feasibility and prepare an individual quotation.

What machining options does our milling service offer?
Our 3-axis machining centres process plastic sheets in length, width and depth. This produces components with bespoke external contours, internal cut-outs and features machined to different depths.
Contours & rounded corners
Circles, ovals, angles, polygons and free-form external contours made to drawings. CNC milling can also be used to round off corners.
Cut-outs & holes
Round and shaped cut-outs, slots, mounting holes or repeated hole patterns for perforated sheets and technical covers.
Recesses & three-dimensional shapes
Pockets, grooves, chamfers, rounded edges and reliefs. Examples include recesses in shaped components and juice grooves in chopping boards.
Typical applications for CNC-milled plastic parts
We produce bespoke components for technical applications, construction, signage and model making. Examples of our milling capabilities include:
- Plastic frames and housing components
- Display covers and protective covers
- Brackets and technical functional parts
- Gears and other technical components
- Perforated sheets and perforated panels
- Lettering, logos and company signs
- Bespoke PTFE seals
- Components for model making and prototypes
Machining formats, material thicknesses and tolerances
Machining format up to 3,000 × 2,000 mm
Our CNC milling machines can process large-format plastic sheets. Whether your component can be produced in the required dimensions also depends on the available sheet format, the geometry and how the workpiece is clamped.
Approximately ±0.3 mm on the X and Y axes
Our CNC milling machines achieve a manufacturing tolerance of approximately ±0.3 mm on the X and Y axes. Please include any special tolerance requirements with your enquiry so that we can assess feasibility for your component.
Material thickness depends on the component and tool
The thickness that can be machined depends on the material, milling tool and geometry. In special cases, thicknesses up to 240 mm are possible with the appropriate setup work. We assess these components separately on request.
Machining in three axes
The X and Y axes determine machining across the surface, while the Z axis controls depth. This enables recesses and three-dimensional machining as well as through cut-outs.
Material and CNC machining from a single source
We hold many of the plastics we process in our own stock. This allows us to combine material supply directly with the production of your milled parts.
We machine a wide range of engineering plastics from our product range. The right material for your component depends on its application and your requirements.
You can also enquire about POM and other plastics not listed in our online shop for your milling project. We will clarify material availability and machining options individually.
- Polyethylene (PE)
- Polypropylene (PP)
- PVC
- PTFE
- Polycarbonate (PC)
- Acrylic glass (PMMA)
- ABS and ASA/ABS
- HPL
We also machine aluminium composite sheets and suitable sheets made from reprocessed plastics. An overview of materials is available in our plastic sheets category.
Individual parts, prototypes and series production
Individual parts
We manufacture bespoke components in quantities starting from one piece. Our calculation also includes programming and machine setup.
Prototypes
For development, model making and preparation for series production, we manufacture your components using the supplied design data.
Series & scheduled repeat deliveries
Larger production batches with several thousand parts and regular repeat orders are also possible. Existing milling programs enable the repeat manufacture of identical components.
Which drawings and CAD files do we need?
For quotation assessment, send us a drawing or sketch with exact dimensions, or your CAD data. Production requires usable design data showing your component’s contours and machining features.
DXF & DWG
For two-dimensional contours, cut-outs and hole patterns.
STEP & IGES
For three-dimensional components and spatial geometries.
EPS, AI & vector PDF
We can convert vector-based files into a format suitable for our CNC machining.
How much do bespoke milled parts cost?
The price depends on the material, geometry, machining work and quantity. We prepare an individual quotation based on your drawings or CAD data.
Programming & setup
We create the milling program from your data and set up the machine for the job. These order-specific costs are spread across the quantity to be produced.
Milling time & machining
The machine time required depends on factors including contours, cut-outs, recesses and material thickness. Milling time is calculated using the applicable hourly rate.
Material & sheet utilisation
The material, sheet thickness and arrangement of parts on the original sheet affect material requirements. Offcuts that cannot be reused are also included in the calculation.
Production planning and lead time
Scheduling according to order scope
As a guide, the lead time for milled parts is approximately 2–3 weeks from ordering and submission of the required drawings or CAD data. The specific schedule depends on material availability, machine capacity, milling time and quantity.
We agree the delivery date individually for your order. Please include your required date with your enquiry.
ERP-based production control
We plan and monitor our production orders using an ERP system with an integrated production control centre. This allows production steps and machining progress to be tracked.
This supports scheduling for individual components as well as series production and repeat deliveries.
Which service suits your component?
Straight-edged sheet cutting
Do you need a sheet with straight edges cut to length and width? Many versions can be configured to size directly in our online shop.
CNC-milled parts made to drawings
For bespoke contours, cut-outs, holes and recesses, we assess your drawings and prepare an order-specific quotation.
Laser cutting
Our laser cutting service is also available for bespoke shapes made from suitable plastics. Materials and configuration options can be found in the relevant section.

Frequently asked questions about our CNC milling service
Can I order individual milled parts or prototypes?
Yes. We manufacture individual parts from one piece, prototypes and larger production series. Send us your drawings or CAD data together with the material, thickness and required quantity for an individual quotation.
Which file formats can S-Polytec process?
We process DXF and DWG for two-dimensional milled parts, and STEP and IGES for three-dimensional components. EPS, AI and vector-based PDF files can also be converted. Contour paths must be closed and the required dimensions clearly specified.
How large can CNC-milled plastic parts be?
Our CNC machining format is up to 3,000 × 2,000 mm. Whether your component can be produced in this size also depends on the sheet format, geometry and workpiece clamping. We assess the material thickness according to your component and the tool required.
What manufacturing tolerances are possible?
Our CNC milling machines achieve approximately ±0.3 mm on the X and Y axes. Include any special tolerance requirements in your enquiry and drawings so that we can assess feasibility for your material and component geometry.
Can I configure milled parts directly online?
We calculate bespoke CNC-milled parts on request using your drawings or CAD data. Online configurators are available for simple sheet cuts to length and width on suitably labelled products.
Are repeat production series and delivery batches possible?
Yes. In addition to individual orders, we manufacture series and repeat delivery batches of identical components. State the total quantity, required quantity per delivery and your dates when submitting your enquiry.
