About CMWTEC
CMWTEC technologie GmbH, based in Runkel-Ennerich, specialises in machines and systems for battery end production. The portfolio includes single machines and fully automatic lines for lead-acid, AGM, EFB and GEL battery manufacturing as well as testing systems for lithium-ion cells: acid filling with vacuum technology, level control, plug insertion, terminal brushing and greasing, marking, labelling, weighing systems and end-of-line tests with E-load modules up to 3000 A. The machines are built in modular design and can be operated individually or as a complete production line; combination machines combine two to five process steps in one system. The DataManager software enables process control, traceability and management of production data. Manufacturing takes place in Germany in a stainless steel and aluminium construction for use in acid-containing environments. Customers are OE battery manufacturers worldwide, especially from the automotive, motorcycle and industrial battery sectors; through its subsidiary CMWTEC India Pvt. Ltd., the company offers local service and support in India.
