Diener electronic GmbH + Co. KG manufactures low-pressure plasma systems for surface pre-treatment of various materials. The main fields of application include: Medical technology, electrical engineering, precision engineering, automotive, semiconductor, elastomer technology, plastics technology, textile technology and electron microscopy. Surfaces are cleaned, activated and also etched. This type of pre-treatment allows for better varnishing or adhesion of the surfaces. This allows, for example, material connections of PTFE (Teflon) with elastomers, plastics or metals. The standard systems range starts with a laboratory small series system with a chamber volume of two litres and continues with production systems with chamber volumes of 5, 25, 30, 50, 100, 240, 600, 2400, 5000 and 12600 litres. Plasma treatments can be performed in multiple compartments in the systems. The systems can also be rented. Special sizes, with volumes of several thousand litres, can be manufactured on request. Several systems are available for plasma pre-treatments on commission order.
