This case describes how the subsidiary of BIBUS Hungary and ACE Stoßdämpfer GmbH are helping Metal 99 Ltd., a specialist in rail-guided wagon and bus equipment, to find a sustainable damping solution for its pneumatically operated sliding doors.
Metal 99 has been successfully cooperating with BIBUS in Hungary for many years in pneumatics and other areas. Since BIBUS is also known as a trusted supplier of complete systems, the request was whether they could supply a large number of high-quality industrial shock absorbers to ensure that the door opening and closing system for wagons is as sustainable and reliable in the end positions as possible and to safeguard continuous operation by also protecting the doors against possible vandalism.
After free sampling and testing, Metal 99 was convinced of the long-term qualities of the hydraulic components supplied by BIBUS. However, their price was higher than that of the Chinese competitors. In order to get closer to the price structure of the dampers selected, BIBUS offered another miniature shock absorber type from ACE Langenfeld. To be on the safe side, they asked ACE to validate the expected maximum overload of the dampers in the event of an emergency stop as part of drop tests carried out in Langenfeld. In the following series of drop tests, the self-adjusting MC225EUMH type miniature shock absorbers not only decelerated the energy, but also withstood the load with unharmed seals and other important components.
