How we have enhanced the automotive pressing process

Friendly Force VS Distance pressing monitoring

After a long experience made with brand Tonsfer ® Auloma has developed a powerful pressing monitoring, with the scope to introduce in the servo press market a device easy to use and easy in set up. This continue evolution has developed now the APM-SI for micro-mechanic applications, but automotive powertrain still our core business. Our APM-BA associated our Servo Press seeking the defects and process abnormalities on source before becoming quality issues. With our servo press you have the promess that defects are catching at source and you will be confident that no scratch parts will be delivered. Our long experience has produced models for applications in engine manufacturing, axle manufacturing and transmission manufacturing.

Auloma provide servo presses with pressing monitoring until 300 kN

Automotive Powertrain Solutions

Thanks to Auloma pressing system, you have the possibility of testing your pressed parts in run by a Force vs Distance analysis. In this way many random testing of finished products can be eliminated. Find defects on source means not add value at scratch parts and save a lot of money. Through or servopresses you can optimize your pressing process to close your six sigma curve. Our solutions are available on the entire supply chain that compose the automotive industry and can be used directly by OEM or in TIER1 and TIER2

Transmission Manufacturing

Several operations in transmission manufacturing are effectuated by press fit insertion. Thanks to a process monitoring is possible detect the defects typical in these applications:

Servo press applications in transmission manufacturing

Applications Control Signature Defects Detected
Bushing insertion Press ram force and position during the bushing insertion Force VS position Undersized or oversized parts as bushing or shaft, crimped or folded bushing, cracked bushing, bushing inserted not to the right depth
Ball Bearing insertion Press ram force and position during the ball bearing insertion Force VS position Undersized or oversized ball bearings, bearing not fully seated, cracked bearings, debris, incorrect bearings
Parts with ORing insertion Press ram force and position during the part insertion Force VS position Missing Oring, rolled Oring, wrong sized ORing
Dowel pin insertion Press ram force and position during the pin insertion Force VS position Missing dowel pins, incorrect size, misaligned pins, pins not inserted to the correct depth
