Additive Manufacturing in High Performance Plastics

Selective Laser Sintering on EOSINT P800 with EOS PEEK HP3 (PEK = Polyetherketon) suitable for prototyping and small series production.

ThermoMelt Technologie on pilot machine (as from 2017) with PPS (Polyphenylensulfid) and PEKK (Polyetherketonketon) suitable for industrial applications.

All three high performance plastics are suitable for high-temperature applications up to 200°C and are inherent flame-retardent and burn antitoxic. Besides their outstanding mechanical properties and chemical resistance they are as well adapted for electrical isolation.

More materials will follow soon. For industrial applications special customized solutions can be developed.

Knowledge and extensive experience

55 years of manufacturing expertise

Our company was founded in 1961 as a carpentry by Wilfried Rauch. Between 1994 and 2005 we specialized in milling processing of thermosetting plastics and thermoplastics. A new era was launched in 2006 when a five-axis robot was installed to feed a new machining center. Today several machining centers produce serial parts mainly for the engineering industry and medical engineering industry.

Additive Manufacturing

A new milestone was reached in 2013 when the EOSINT P800 für PEEK was installed. Right from the beginning our additive manufacturing department was specialized in high performance plastics.

Based on our roots in small series production and because of sophisticated materials our main focus is more on serial parts than on rapid prototyping.
For series applications we offer consulting for your R&D and design departments. A design matching the special facts of additive manufacturing is mandatory for a successful implementation.

Technology: New laser sintering technology „ThermoMelt“

The absolutely new laser sintering technology ThermoMelt opens a new approach to eliminate the previous disadvantages in additive manufacturing with high performance polymers. The materials get less polymerized because of the processing in low temperature. The recycling rates show significant improvement and unpowdering of the parts becomes quite simply. Additionally smoother surfaces and better tolerances are feasible. The higher recycling rates as well as the lower building chamber temperatures decrease the costs significantly for industrial applications.

ThermoMelt was developed and patented by Airbus Group Innovations. Rauch CNC Manufaktur is the industrial partner in the development collaboration. Systems engineering will be done at LSS in Dortmund . Lehmann u. Voss in Hamburg signs responsible for material development and supply. As the specialist for PEEK we yield our wide experience in optimization and processing of industrial parts with high performance plastics for laser sintering into our development collaboration.

After completion of the first tests the pilot machine will be installed at our factory in spring 2017 to pass extensive second test series with parts. During 2017 the optimized pilot machine will be available as the worldwide first commercial ThermoMelt machine for industrial applications in series production.

All three partners of this collaboration together are able to customize the processing of ThermoMelt as well as the machining technology and the materials to the needs of your industrial parts. We adapt technique and material to the component and not the reverse!

formnext 2016

Again a prosperous trade fair participation looms at the Formnext in Frankfurt / Germany in November 2016. Focus was laid on introducing the new additive manufacturing technology ThermoMelt.

The promising potential of this groundbreaking technology was explained to many interested visitors to our booth. In face-to-face meetings the technical requirements for series production with ThermoMelt and high performance plastics like PEKK and PPS had been intensively discussed.

The visitors showed as well great interest in the proven SLS technology with PEEK. The immediately available SLS technology is still the first choice for many applications - especially for rapid prototyping.
