About E. Wehrle GmbH
E. Wehrle GmbH is a German company with two business fields: injection molding production of precision parts made from thermoplastics (Business Unit PRECISION PLASTICS) and flow measurement technology for water and heat consumption monitoring (Business Unit METERING). At the Wehrle plant, precision plastic parts are produced from the customer's idea through to series production: The range of services covers component development and simulation, tool design and toolmaking (CNC milling, EDM), injection molding of standard, engineering and high-performance thermoplastics as well as the assembly of subassemblies with seals, metal parts and electronics. Automated handling systems take care of part removal and transfer in series production. Quality assurance accompanies the entire process, from incoming goods inspection and process monitoring of injection molding parameters through to functional and leak tests on finished subassemblies. Logistics supports just-in-time and just-in-sequence deliveries. Customers come, among others, from measurement and control technology, the automotive industry, medical and laboratory technology as well as drive and appliance engineering. In the METERING area, Wehrle produces water meters such as single-jet dry-run meters and rotary piston cartridge meters of the MODULARIS series for building and consumption monitoring.

Materials and Processes
Thermoplastics (granulate)
Standard, engineering and high-performance plastics as starting material for precision injection-molded parts with defined properties such as temperature resistance, strength and chemical resistance.
Tool steels and alloys
High-strength steels and special alloys for injection molds, manufactured in the company's own toolmaking department using CNC milling technology and EDM machines.
