Precision production process seals automotive components

ElringKlinger (GB) has designed and developed a precision manufacturing process claimed to seal automotive parts, increase production, reduce energy emissions and potentially replace the traditional metal gasket.

In a statement, the company said it has invested £250,000 into research and development, allowing the in-house development of a fully automated cured-in-place (CIP) technology production line.

The CIP technology took three months to fully develop and operates using tunnel oven elements heating the castings to 115ºC and is in operation eight hours a day, producing 20,000 units a year — on average 85 sealed engine castings daily.

The cured sealant is applied through a high-pressure nozzle at an accuracy of 100 microns high and 4mm wide, within a control tolerance of ±25 microns.

Mike Swankie, engineering manager at ElringKlinger (GB), said: ‘The use of CIP is growing rapidly since it is advantageous in terms of high precision, saving energy and space and reducing waste.’
