VEHICLE PARTS PRESS AS GOOD AS NEW AFTER UPGRADE

Service News Monday, August 29, 2011: Hytec Group of Companies

Tectra Automation and Hytec joined forces in a project to upgrade an old and out of use vehicle parts press in the production line for MA Automation, a motor parts manufacturer in Rosslyn, Pretoria.  The old 201 press needed improved functionality; with more user friendly electrical controls with increased capacity.

“The automotive industry is one of the largest that Tectra Automation is involved in, and it has a longstanding relationship with the client. We were awarded the contract due to this ongoing relationship and the high standard of our service and solutions,” explains Georg Venter, Divisional Manager - Electric Drives and Controls, Tectra Automation.

Hytec upgraded the hydraulics, the pumps, valves and electronic control valves, while Tectra Automation was responsible for the new control components. “The machine used to be a hard-wired relay and contactor control system that required a lot of cabling and was difficult to reconfigure.  A Profibus system has been used to minimise cabling between machines and control. The new system includes a Bosch Rexroth L40 PLC with VEP40 colour touch screen. The client was very happy with the user friendliness of the interface,” enthuses Venter.

Hytec provided the hydraulic manifold block and worked together with the client to integrate the old hydraulics into the new. “The press is recipe driven with the parameters programmed in. The client’s requirements were to regulate and influence the speed and force of the press, which we were able to do with the Bosch Rexroth A4V750 horsepower controlled pumps that we installed,” explains Maurice Bloemendal, Technical Manager, Hytec.

Benefits of this system are stepless programming with no mechanical components to maintain; and programme changes that can be made on site.
