Sealing Technology

You have an idea — we’ll seal it!

Leaks cost you both time and money. This means that a small component can quickly become a big problem. To help you avoid such issues, we manufacture bespoke seals for your specific applications. They are always engineered to the highest technical standards. They are also selected for maximum cost-effectiveness. Whether standard or custom-designed, dynamic or static: we’ll seal it!

Plastics Technology

We’ll make the chips fly for your component

Do you need a specialised component?
Perhaps a lightweight precision part for the aerospace industry? Or a custom component that is chemically resistant for use in plant engineering? Or a flame-retardant guide element? Whatever your industry or requirements: We can machine over 160 types of plastic to turn your design into a finished component.

Additive Manufacturing

Your idea – we’ll print it

Do you need custom-shaped prototypes, components that fit perfectly in your machine room or production parts made of fibre-reinforced plastics? We can manufacture all of these items and much more using additive manufacturing with post-processing.

Development partner

Our joint path to a solution

Are you looking for a partner who can manufacture your component and contribute ideas from the very beginning? With us, you’ll be assigned your very own dedicated contact person who will be with you every step of the way, from the initial concept through to delivery.

Compliance & Admissions

We make compliance easy to understand

If you are facing a challenging certification issue or are looking for a proven solution, we are here to help. We are able to offer guidance on material selection and can provide the relevant declaration of conformity promptly.

LFAM

We are able to transform large-scale ideas into concrete realities.

Large-format additive manufacturing combines additive 3D printing with 5-axis CNC milling, enabling the production of plastic components that conventional methods cannot produce due to their size or geometric complexity. This innovative process is already being successfully applied in the field of mould making and the design of custom yacht interiors. It is cost-effective, with a minimum order quantity of just one.
