For greater process reliability and a wider process window in injection moulding, as well as significantly longer maintenance intervals, Dressel + Höfner Automotive now relies on DLC-coated ejector pins for venting from standard parts manufacturer Knarr as a matter of course in its injection moulding tools.

When the automotive industry demands highest quality, the experts at Dressel + Höfner Automotive, a Welp Group company based in Neustadt near Coburg (southern Germany), are highly sought-after partners for OEMs. This is where intelligent system and complete solutions in plastic injection moulding are created. Thanks to the effective use of synergy effects within the group, the company can act as a full-service provider for projects on request, seamlessly covering all stages from product development through toolmaking, injection moulding, assembly and painting, right through to delivery to the customer's production line.

Maximum process reliability and stability are required when supplying an OEM’s assembly line. Consistently high quality and absolute adherence to delivery dates are taken for granted. One hundred percent good parts are expected, and if this is not met, a customer complaint can quickly become costly and resource-intensive to resolve. For this reason, those responsible at Dressel + Höfner Automotive invest considerable effort to prevent complaints reliably from the outset.
