Cured in Place Technology

Cured in Place Technology

Cured in Place (CIP) technology was designed and developed on site by ElringKlinger (GB). It is a sophisticated precision manufacturing process to seal automotive parts, increase production, reduce energy emissions and potentially replace the traditional metal gasket. Advantageous in terms of high precision, saving energy, space and reducing waste, CIP achieves high productivity and its usage could considerably reduce environmental waste in the engineering sector.

The prototype was developed in the R&D department on the Redcar site, where experienced engineers adapted a robot dispensing unit for the sealant medium. The engineers then analysed the capability of the new sealing paths against traditional manufacturing techniques in achieving strict design parameters, to further refine the manufacturability of the design. 

The CIP technology took three months to fully develop and install and takes up just 64 square metres of space on the factory floor. It operates using tunnel oven elements heating the castings to 115 degrees celsius and is in operation eight hours a day producing 150,000 units a year. The cured sealant is applied through a high pressure nozzle at an outstanding accuracy of 100 microns high and 4mm wide, within a control tolerance of +/- 25 microns setting a benchmark for other in UK engineering firms and creating a highly innovative solution for engine castings and other automotive applications. 

Confident in the results of this technology, ElringKlinger (GB) hopes to develop CIP further, alongside progressing the firm’s environmental responsiveness as the energy required for curing is less, meaning its carbon dioxide emission is lower.
