Friedrich Grohe AG of Germany has developed a new sandwich molding process for the manufacture of operating levers for sanitary fittings.
The composite product, called Solitan, combines Grivory GV-6H partially-aromatic nylon from EMS-Chemie and acrylonitrile butadiene styrene (ABS). The end product meets Grohe’s stringent demands for chroming quality and high flexural strength.
The core element of the new operating levers is made of Grivory nylon reinforced with 60 percent glass fibres. This serves as a mechanical support that can withstand stresses applied during use.
The injection molded core is sheathed with ABS to give a smooth molded part without joints. The finish does not require reworking prior to galvanizing. Since the nylon provides flexural strength, the lever does not bend enough to cause cracking or peeling of the galvanized layers.
