Since its foundation in 1981, BGS has been one of the pioneers of radiation treatment using accelerated electrons (beta rays) and gamma rays. In Europe, we are second to none in our mastery of the sophisticated processes involved in the refinement of plastics and sterilization of, for example, medical devices. BGS was at the forefront of developing and shaping ground-breaking methods that are state of the art today.

Based on mutual trust, the company has been successfully cooperating with Uwe Stenglin since 1986. BGS is the only known service provider with extensive experience in the field of radiation crosslinkable ETPs (engineering thermoplastics) and TPEs (thermoplastic elastomers).

By radiation crosslinking, ETPs and TPEs become “non-meltable” polymers.

This significantly improves the heat, chemical and abrasion resistance.

The “creep under load” effect improves a great deal, especially at high temperatures. Expensive high-temperature polymers can often be replaced by easy-to-process engineering thermoplastics plus radiation crosslinking.

Radiation crosslinked products have a “MEMORY effect”, i.e. the components have assumed their shape during radiation crosslinking and tend to return to this shape even after distortion if they are released of tension at a higher temperature.

Innovative potential has been identified with all Rotfeld network partners.

The Richard Bergner Holding GmbH & Co. KG, RIBE for short, is headquartered in Schwabach, where it develops and produces fastening systems, technical springs and electrical fittings.

The ROTFELD network partnership focuses on the development and manufacture of connection and fastening elements made of or in combination with ETPs (engineering thermoplastics), which are converted from a thermoplastic to a non-meltable material in a special process.

These components are characterised by their low creep under load, especially at high temperatures. The chemical resistance is improved significantly. Abrasion resistance and dimensional stability are excellent as well. 

Any colour is possible.

Fastening elements, e.g. in the engine compartment of a car, withstand extreme temperatures of more than 270 °C.

These products are perfect for lightweight construction, as they are 25 to 30 % lighter compared to an aluminium screw, for example.

Wilhelm Weber is one of the inventors of “multi-colour injection moulding” as well as one of the pioneers of multi-component technology. The manufacture of dynamic tools as well as turning devices that can handle several components in a single process and injection moulding technology are all combined under one roof. 

Wilhelm Weber develops and manufactures components for electrical engineering, automotive, medical technology, consumer goods and technical applications.

In the Rotfeld network, the focus is on hard/soft composites with ETP/TPE with the associated tools and injection moulding processes. Hard/soft connections are possible with almost any ETP. Highly specialised toolmaking is a prerequisite to develop innovative components, not only for thermoplastics but also for ETP/silicone.

Wilhelm WEBER develops and plans high-temperature components made of radiation crosslinkable materials. For this project, the network partners BGS (Beta-Gamma-Service) as the service provider and Uwe Stenglin of ROTFELD Consulting cooperate with WEBER. Often, difficult-to-process HT polymers can be replaced by this technology. Temperature resistance (no melting) and extreme improvement. Deformation under load and a dramatic improvement of the chemical resistance are only the top highlights.

We are GRAUTS and have over 20 years of experience in plastics processing, process optimization of plastics manufacturing, and prototype development.

It all started a few years ago in a well-known injection molding company in prototype production. At that time, the idea of single filament production was born, and in the beginning of 2022, we founded the company GRAUTS, which specializes in filament for 3D printing and prototyping.

We produce all common filaments such as PLA, PETG, ABS and PMMA. Furthermore, we also have industrial technical filaments in our range, such as different materials with carbon, glass fibers as well as flexible filaments. Our high-quality products are suitable for most applications, without time-consuming adjustment of printing parameters. Moreover, our filament convinces with high layer and print bed adhesion, as well as constant dimensional stability for excellent mechanical and physical printing results.
