Beckwood’s cross-functional teams work together to streamline every press we design for ultimate sustainability, and we strive to implement only the most energy efficient components. By doing this we minimize waste and improve the overall performance of our machines – providing a substantial impact to your operations.

We focus on sustainable technology because it plays a significant role in curbing the environmental impact of our company and our machines. We continually work with our partners to perfect and implement press technologies that enable customers to enhance their manufacturing processes, improve energy consumption rates, increase material efficiencies, decrease noise pollution, and reduce emissions.

Variable Frequency Drive (VFD)

A Variable Frequency Drive (VFD) is a motor controller that allows the frequency and voltage supplied to an electric motor to vary based on the requirements of the press load. Beckwood presses with VFD Technology offer dramatically increased energy efficiency when compared to traditional hydraulic systems because the VFD draws energy ‘on demand’ as opposed to the constant demand associated with standard motors. This ability to vary the energy output, by rotating the motor only as needed, also greatly reduces noise levels.

VFD Technology allows the user to monitor pump efficiency directly through the press’ HMI. Signs of decreased efficiency and premature pump wear can be detected early, aiding in the prevention of unexpected pump failures and unplanned downtime. Beckwood customers have the ability to set their own acceptable pump performance standards, thereafter receiving warning notifications if the pump’s performance falls outside the specified range.

Pneumatic Dwell

Beckwood’s Pneumatic Dwell System is an ideal solution for manufacturers looking to save energy during long dwell cycles. A small pneumatically-powered hydraulic pump is integrated into the hydraulic circuit, allowing the primary electric motor and pump to be ‘turned off’ during the dwell cycle.  This minimizes electrical power consumption and reduces operating noise.

In a typical operation, the press’ primary electric motor and pump are used to close the tool/mold and develop the appropriate ram force. Once ram force is established, a pressure lock valve is used to hold the desired pressure in the cylinder(s). Over time, if a drop in pressure occurs as sensed via a pressure transducer, the pneumatic pump reacts by adding additional pressure back into the cylinder circuit to reach the desired force. The system functions ‘on demand’ and requires very little shop air.

Soft Starter

A soft starter protects the motor and ancillary equipment by limiting the initial inrush of current and reducing the mechanical shock generated during startup. By gradually ramping-up the motor’s speed instead of accelerating it using a full voltage connection, you decrease the mechanical stress on the motor and shaft, extending the lifespan of your equipment.

Soft starters are the economical choice for applications requiring speed control during motor start-up. Since they require less space than variable frequency drives, they are the ideal solution for presses with space limitations. At Beckwood, we understand the impact of rising energy costs on your operation, that’s why we install soft starters on every machine with a motor larger than 100HP. Upon request, however, they can be added to motors of any size.
