About Geiger Gruppe
Founded in 1961 as a mould-making company, Geiger Gruppe is a family-run mid-sized enterprise headquartered in Nuremberg with more than 200 employees. The group comprises HG Hans Geiger Formenbau GmbH, HG Hans Geiger Spritzgießtechnik GmbH in Nuremberg, and Reiter HG Geiger Kunststofftechnik GmbH at the Hilpoltstein site. The company manufactures technical precision parts by injection moulding, including components made from demanding high-temperature materials such as PEEK, Trilliant, PA66, PBT and LCP, as well as hybrid components with overmoulded metal inserts made of brass or aluminium. The value chain extends from consulting and tool development through mould making with up to 108 cavities, injection moulding including in-mould assembly and reel-to-reel band overmoulding, to the assembly of components with up to 29 individual parts, finishing, packaging and logistics. Customers come from the automotive supply, medical technology, safety technology, electrical engineering, battery technology, hearing aid acoustics and mechanical engineering sectors.

Materials and Processes
PEEK
High-temperature material for technical precision parts with demanding thermal requirements.
Trilliant
High-performance high-temperature material for demanding injection moulding applications.
PA66
Standard material for technical precision parts, e.g. sealing elements for batteries.
PA66 GF13
PA 66 with 13 % glass fibre content, e.g. for MCP connector housings in the automotive sector.
PA66 radiation cross-linked
Radiation cross-linked after injection moulding, thereby acquiring thermoset properties.
PBT with V0 flame retardant
Flame-retardant material system for connectors in mechanical engineering.
LCP
Liquid-crystal polymer for filigree parts such as contact carriers for hearing aids.
Brass
Overmoulded brass bushes in connectors (hybrid components).
Aluminium
Overmoulded metal partner in plastic-metal hybrid components.
In-Mould Assembly
Assembly of parts already during the injection moulding process inside the tool, e.g. as a 4+4-fold tool.
Reel-to-Reel Band Overmoulding
Overmoulding of stamped strip in continuous strip feed, including 8-fold for contact sliders.

Quality
Geiger Gruppe pursues a zero-defect philosophy with active error avoidance from the start of the process; the injection moulding process is monitored, among other things, with cavity pressure sensors, and every assembly undergoes a quality inspection. As a supplier to the automotive supply, medical technology and safety technology sectors, product quality and safety come first.
