Special-purpose machinery & plant engineering

We supply plastic parts and assemblies precisely tailored to our customers’ technical requirements – from single-piece production to full-scale series. Precise, adaptable, and ready for any function.

Custom plastic components

We manufacture custom-engineered plastic components for housings, mounts, or covers – perfectly adapted to the respective machine environment.

Functional assemblies for moving components

Moving parts such as guides, coupling elements, or torque-critical connections are preassembled in-house with reliable processes – including custom test fixtures when required.

Hybrid components with metal inserts

Metal-plastic combinations enable robust components with integrated functions – for example, through overmolded bearings, threaded inserts, or bushings.

There are no off-the-shelf standards in special-purpose machinery – only tailored requirements. That’s exactly what our plastic parts and assemblies are designed for. We deliver functional single components, assembly-ready modules, or complex hybrid parts – all precisely built to specification.

Typical applications include housings, brackets, spacers, coupling elements, or dynamic guide systems. Our services cover tool-optimized design, in-house mold making, and flexible production – from small batches to recurring series.

For mechanically demanding applications, we offer overmolded metal inserts such as bearing sleeves, threaded inserts, or axle mounts. This allows multiple functions to be integrated into a single component while significantly reducing assembly effort.

Our focus is on precise execution, reliable manufacturing processes, and consistent quality assurance. With defined standards and custom solutions, we support machinery builders from the initial idea to the fully assembled unit.

FAQ

Which plastic components are typically used in special-purpose machinery?

Special-purpose machinery commonly requires housings, brackets, guide elements, spacers, and functional assemblies. Depending on the application, thermoplastic materials with high dimensional accuracy and load resistance are used.

Do you also produce single parts or small batches for special machinery?

Yes, our processes are optimized for flexible batch sizes. We manufacture both single components and series parts, supporting our customers from the prototyping phase through to final production release.

Are combinations of plastic and metal possible?

Absolutely – we offer insert molding of metal elements such as threaded bushings, bearing sleeves, or axle mounts. This enables robust hybrid components with integrated functionality.

How do you ensure that a part fits the machine design precisely?

Our engineering team works closely with customers throughout the design process. Combined with in-house mold adjustments, laser measurement, and defined quality checks, we ensure accurate fit throughout the entire production cycle.

Which plastics are suitable for moving or high-stress machine components?

Glass fiber reinforced polyamides (PA-GF), POM, PC-ABS, and other high-performance thermoplastics are ideal – depending on specific requirements such as temperature resistance, friction, mechanical load, or media exposure.
