miCa lamiNates – samiCaNit, PamitHerm, miglasil

The term mica refers to a group of minerals with excellent fissility. The reason for this fissility is the layered silicate lattice. The term mica comes from the Latin word micare, which means „shine“ and is a reference to the shiny appearance of this mineral. VonRoll mines this material in its own mines and uses a special method to produce muscovite or phlogopite-based mica paper.If we create layers of mica paper, press it using a silicone or epoxy resin and let it harden, we obtain firm material for tem-peratures up to 900 °C or flexible Miglasil for temperatures up to 1200 °C.

main advantages:- excellent electrical and thermal insulation - mechanical stability at high temperatures

It comes in sheets, tubes and as finished parts.

CNC fabriCatiNg of ComPosites aNd tHermoPlastiCs (iN Prague - CZ)

Since 2009, we have had our own technological facilities for fabricating of composites. Our production equipment includes saws, grinders, drills, milling machines, lathes and three- and five-axis CNC machining centres. The aim is to implement custom manufacture of any component according to customer drawings or data with the required accuracy, ranging from 1 piece to thousand-piece series. The production quality has been guaranteed with the ISO 9001:2013 certificate since 2014. We run a two-shift operation. According to the requirements, we also perform additional operations such as painting, gluing and assembly of metal threaded inserts HELICOIL. Furthermore, we cooperate with long-standing partners with other technologies, such as water jet cutting, punching, moulding of thermosets made of BMC and SMC compounds or surface finishing. We also offer fabricating of components of sheets or rods from thermoplastics such as PA, PP, POM, PE, PC, PTFE, PEEK, including any shaping, or also from laminated wood for oil transformers. Recently, we have expanded our product line to include the manufacture of parts made of copper materials CuSn, even as finished parts, including deburring, shaping and galvanic finishes. This production is performed separately from the fabricating of insulating materials.
