About Corina Weimer
Corina Weimer GmbH & Co. KG in Merenberg is a family-owned plastics processing company specializing in injection molding. The company produces standard injection-molded parts, fast-runner and slow-runner orders (cycles of over 15 minutes per shot), TSG parts as well as foamed and blowing-agent-containing injection-molded parts, which can also be electroplated. Special features include in-mould technology with back-molded decor or textile, insert parts made of metal-plastic, hard-soft and wood combinations, as well as parts made of wood-filled thermoplastics (wood plastic). An in-house tool and mold making department produces injection molds – from standard, slider, jaw and core-pull molds up to 2K tools – and also handles maintenance, servicing and special machine construction for its own needs. Downstream processing includes ultrasonic and hot-air welding, pad printing, screen printing, hot embossing and powder coating. Customers come from industries such as construction, environmental technology, railway accessories, filtration technology, electrical, brush and furniture manufacturing as well as household goods.
