With two years under its belt using the servo-mechanical press in hot-stamping die set-up and preserial production, Batz now has a clear idea as to press performance in this application. Energy savings was an immediately identified result.
“Energy consumption was one logical and expected advantage,” explains Andoni Alonso, hot-forming business manager for Batz. “With hydraulic presses in our facilities, we were used to their high energy consumption. With this servo-mechanical press, energy expenses have dropped dramatically and this is something to take into account nowadays.”
More surprising was the equipment’s effect on part quality.
“During the set-up of new dies, we realized that we could more easily achieve higher-quality parts than in our conventional hydraulic presses,” Alonso says. “We attribute this in part to the higher drawing speed of the servo-mechanical press. The servo control also allows us to simulate the end user’s press conditions, which ensures that part quality at a customer’s facility will be comparable to ours.”
Alonso advises that proper training is necessary to gain the full advantages of this hot-stamping technology, a lesson learned during Batz’s adoption of the new equipment.
“Operating mechanical presses versus hydraulic presses presents some differences,” he says, “so it was necessary to train personnel in understanding the data-introduction system for the servo-mechanical press. Once proper training was achieved, we realized that the system attains the same force control and even greater flexibility than we had been accustomed to when using hydraulic presses.” MF
