About WINTER

GS Kunststoffverarbeitung Winter GmbH produces injection-molded parts from thermoplastics as prototypes, small and large series and has been active in plastics processing since 1946. In Eichenzell-Welkers, the company manufactures thermoplastic single- and multi-component articles with shot weights from 6 to 3,600 g on more than 40 injection molding machines with clamping forces from 150 to 6,500 kN. The value chain includes design and development, prototype construction for thermoplastic toolmaking, toolmaking, tool management and maintenance as well as injection molding production with insert technology and overmolding. The parts are then painted, electroplated or finished with pad printing, joined by ultrasonic or vibration welding or bonding, and assembled into modules. Customers come from pump and filter technology, automotive engineering, medical technology, electrical engineering, hairdressing equipment and the household goods industry. The company is certified to DIN EN ISO 9001:2015 and operates in three shifts with around 70 employees.

Quality and Certification

An experienced quality team works in three shifts in accordance with DIN EN ISO 9001:2015 and designs, manufactures and inspects every injection-molded part; consistent regular quality controls lead to low defect and scrap rates. The quality and energy management systems are regularly reviewed through internal and external audits.
