Established in 1968, Weldmac Manufacturing is a job shop that offers laser cutting and welding for stainless steel, aluminium, titanium, Inconel, Hastelloy and other alloys, as well as machining, press-brake forming, hydroforming and spinning. The company’s latest machinery purchase, a custom 800 T triple-action hydraulic press from Beckwood, supplements its existing 150 and 450 T triple-action presses.
“At double the tonnage of our other triple-action presses and with a larger bed size, we’ve already increased capabilities by 50%,” says Weldmac president Marshall Rugg. “Ease of use due to programmability should push capabilities to a 60-70% increase. Operator capability enters into it, but the controls on this press only will make jobs easier for a good manual press operator.”
The triple-action press consists of a punch or forming tool on the main draw ram, a clamp ram in the middle, and a knockout cylinder and/or bed cushion on the bottom. The clamp ram, which offers individual tonnage control on each cylinder, is engaged throughout the forming process to control material flow and reduce wrinkling and tearing within the part. By giving operators the ability control material flow, they achieve greater success in forming parts.
Proportional control valves regulate the bed cushion, enabling dynamic control through four different travel zones. Through the HMI and recipe settings of the press, the operator can specify a desired bed cushion force at any position within each zone.
“We excel at building complex components and assemblies, and that work continues to increase,” says Rugg. “We’ve added customers that usually come to us with one problematic part or assembly, and that leads to more business. When we do a good job, a new customer gives us more things to do. New press capacity and capability helps us handle that.”
