Innovation in Motion

Challenge:

After a new product launch, an Appliance manufacturer procured an automated manufacturing line from a Special Machine Builder. The new product had stringent process quality requirements for the metal forming operations to be performed on the new line.

In addition, the manufacturer had a requirement to eliminate use of hydraulics in the plant to reduce floor space, take advantage of being environmentally cleaner, provide significant energy savings, and provide quieter operation.

The customers’ 'no hydraulics' mandate created unique challenges for the Machine Builder due to the high forces required in the metal forming stations using coining and piercing presses.

Solution:

The Machine Builder considered using electro-mechanical actuators (EMA) but found the large size and high cost of EMA technology was prohibitively expensive. Those issues mean an EMA would not meet their project requirements. In addition, there were concerns about EMA screw life due to the “spike loads” the actuators would be subject to during production.

After careful consideration, the Machine Builder selected Kyntronics SMART Hydraulic Actuators (SHA) for the new machine. The SHAs were rated for 58,000 lbf (258kN) of force and were provided in a parallel configuration, which provided the force required in the available space envelope.

Results:

  • The SHAs addressed the customers “No Hydraulics” mandate eliminating the need for an HPU and hydraulic infrastructure resulting in a clean working environment, quieter operation, and substantial energy savings.
  • Part quality exceeded the new product’s stringent requirements on the Coining and Piercing press station, even with the high forces required for the metal forming operations.
  • The SHA provided very reliable, maintenance-free operation despite the “shock loads” that were present in the metal forming operations.
