Plastic machining comprises the precise production of technical components by machining processes such as milling and turning. It enables the manufacture of complex geometries, tight tolerances and individual solutions for industry, mechanical engineering, medical technology and many other applications.
We manufacture high-quality plastic parts exactly to your specifications – from individual pieces to series production. The basis is your technical drawings, CAD data or sample parts, which we turn into precise components using modern CNC machines.
Overview of plastic machining processes
Machining of plastics comprises several processes that are used depending on the component geometry and requirements. These include in particular CNC milling and turning, but also drilling, sawing or thread cutting.
Milling produces complex geometries, contours and pockets, while turning is used for rotationally symmetrical components. Supplementary machining steps such as drilling or countersinking ensure the final functionality.
The choice of the right process has a decisive influence on the cost, quality and feasibility of a component.
Milled parts made of plastic
The production of milled parts takes place on high-performance CNC machining centres that ensure high dimensional accuracy and clean surfaces. Milling plays to its strengths particularly with complex geometries, recesses or multi-sided machining.
We process all common thermoplastics, including POM, PA, PE, PET, PVC as well as high-performance plastics such as PEEK. Every material brings specific properties that must be taken into account during machining and later application.
Milled parts made of plastic are used above all when precise contours, hole patterns or individual component geometries are required. Typical applications are found in mechanical and plant engineering, in electrical engineering or in the food industry.
Thanks to our manufacturing capabilities, both individual parts and larger series can be produced economically. Quality remains constant, regardless of the quantity.
Milling or turning – which process makes sense?
| Criterion | Milling | Turning |
|---|---|---|
| Geometry | complex, multi-sided | round, rotationally symmetrical |
| Typical parts | sheets, contours, housings | bushes, shafts, sleeves |
| Flexibility | very high | medium |
| Cost-effectiveness | for complex parts | for series and round parts |
The decision between milling and turning depends heavily on the geometry of the component. Milling is suitable for complex shapes, sheet machining and components with different planes. Turning, on the other hand, is ideal for round, rotationally symmetrical parts with uniform diameters.
The decision between milling and turning depends heavily on the geometry of the component. Milling is suitable for complex shapes, sheet machining and components with different planes. Turning, on the other hand, is ideal for round, rotationally symmetrical parts with uniform diameters.
In many projects, both processes are combined in order to unite economic and technical advantages.
Turned parts made of plastic
For rotationally symmetrical components, turning offers a particularly efficient solution. Our CNC lathes enable precise production of diameters between 5 and 300 mm.
Turned parts are characterised by exact fits, uniform surfaces and high repeat accuracy. Especially with components such as bushes, sleeves, rollers or shafts, this process is particularly economical.
In turning too, we process various engineering plastics, matched to the respective application. Factors such as load, temperature or chemical influences are incorporated into the material selection.
Having plastic milled and having plastic turned
If you want to have plastic milled or turned, the focus is usually on specific components: drawing parts, prototypes or series components. Clean data, a suitable material selection and an economical design are decisive.
Typical search queries such as "have plastic milled", "have plastic turned", "CNC plastic machining" or "plastic parts to drawing" aim precisely at these services. We implement these requirements precisely – from simple geometries to complex components.
Industries and applications
- Mechanical engineering: guides, sliding sheets, covers
- Plant engineering: functional components, cladding, spacers
- Food technology: hygienic, chemical-resistant components
- Electrical engineering: insulating parts and carrier components
- Medical technology: precise and durable components
- Conveyor technology: rollers, slide rails, wear parts
- Vehicle construction: lightweight and corrosion-resistant components
In addition, individually manufactured plastic parts are used in many other areas, wherever weight, durability and cost-effectiveness play a role.
Material selection and properties
The choice of the right plastic has a decisive influence on the function and service life of a component. Depending on the type, engineering plastics offer different advantages such as high strength, good sliding properties or chemical resistance.
POM, for example, is suitable for precise mechanical engineering components with good sliding properties, while PE is often used in food or chemical technology due to its chemical resistance. PA impresses with its toughness and wear resistance, while PEEK is used for demanding high-temperature applications.
We support you in selecting the right material and take both technical requirements and economic aspects into account.
Manufacturing to drawing or sample
Implementation is carried out exactly to your specifications. You can provide us with technical drawings, CAD data or sample parts. On this basis, we check feasibility, optimise the design if necessary and ensure economical production.
Particularly with complex components, the advantage of close coordination in advance becomes apparent, in order to optimally align material, machining strategy and tolerances with one another.
Individual parts, prototypes and series
Our production is designed for different requirements. Individual parts are often needed in development or for special solutions, while prototypes serve validation and testing. Small series enable flexible supply before series production is established.
Larger quantities can also be produced efficiently without compromising on quality.
Tolerances and quality assurance
Tolerances play a central role in plastic machining. Materials react differently to temperature, stress and machining, which is why experience and precision are decisive.
Typical tolerances are – depending on the material and the component geometry – in the range of a few tenths of a millimetre. Factors such as material expansion, moisture absorption or internal stresses must be taken into account.
These properties should already be planned for in the design in order to avoid subsequent fit problems.
We manufacture to defined tolerance specifications and carefully inspect every component. In this way we ensure that function, fit accuracy and quality are permanently guaranteed.
Typical mistakes in plastic machining
- Unsuitable material selection for temperature, load or media contact
- Tolerances that are too tight without taking expansion and moisture absorption into account
- Failure to take distortion and internal stresses into account
- Unsuitable wall thicknesses and missing design radii
- Sharp edges without deburring or chamfers
- Unsuitable joining concepts (e.g. press fits with soft materials)
- Lack of coordination between design and production
- Ignored machining direction with fibre-reinforced plastics
- Insufficient surface requirements defined in the drawing
- Missing functional testing under real operating conditions
Early coordination considerably reduces these risks and leads to economical, functionally reliable components.
Advantages of plastic compared with metal
- Low weight with simultaneously sufficient strength
- High corrosion and chemical resistance
- Good sliding and wear properties
- Electrical insulating capability
- Lower noise and vibration development
- Economical production with complex geometries
- No post-treatment such as painting or coating required
- High design freedom in form and function
- Good resistance to moisture and many media
- Reduced maintenance effort in many applications

FAQ on plastic machining
Which data is needed for production? Ideally CAD data such as STEP or DXF as well as technical drawings with dimensions.
Are small quantities also possible? Yes, we manufacture both individual parts and series.
Which tolerances are possible? The achievable tolerances depend on the material and component and are agreed individually.
Can high-performance plastics also be machined? Yes, we also process demanding materials such as PEEK for special applications.
