PAULSTRA CRC, a division of Hutchinson, is a supplier of hydraulic engine mounts and suspension components to the automotive industry. Located in Grand Rapids, Michigan, PAULSTRA CRC currently employs eight Stäubli robots in four cells for the assembly of hydraulic motor mounts.

The application has allowed PAULSTRA to reduce the number of operators in each cell from three to one, and help eliminate air bubble contamination problems by having the robot swish the parts while in the liquid (Plate’1). Robotic automation has also eliminated blind positioning operations. The application involves assembling seven separate components on a three-position index table located in the glycol tank. Parts are loaded and assembled, then indexed into a press for staking and crimping operations, all of which take place in the glycol solution. The assemblies are then removed and loaded into a wash/dry system. After weighing and dynamic testing, the engine mounts are shipped directly to the automotive assembly plant. PAULSTRA designed and integrated the systems in-house at their Grand Rapids, Michigan facility.

PAULSTRA is currently implementing a new robotic spray system for cementing the elastomer component to the steel mount using Stäubli RXPaint90 robots approved for use in hazardous environments.
