At Wonsten, we’ve watched the tube and pipe bending industry evolve. We’ve built robust hydraulic machines for years, but we also recognize that the demands of our customers are changing. Today, the focus is on extreme precision, rapid changeovers, and minimizing operational costs. That’s why the industry is seeing a massive shift towards all-electric CNC bending technology.
Here is a breakdown of why our clients are increasingly requesting our all-electric models over traditional hydraulic setups.
The Accuracy Issue
The biggest challenge with hydraulic bending is consistency. Hydraulic fluid changes viscosity as it heats up during operation. This means a hydraulic machine behaves differently at 8:00 AM than it does at 3:00 PM. To maintain accurate bends, operators must continually adjust the machine settings throughout the shift. This manual intervention slows down production and increases the likelihood of human error.
Wonsten’s electric CNC benders eliminate this problem entirely. By using advanced servo motors for every movement, our machines offer true repeatability. The machine executes the exact same motion profile every time, completely independent of ambient or operational temperatures. This guarantees that the first part and the last part of a production run are identical.
Operational Efficiency and Speed
Time is money on the shop floor. Electric benders offer significant advantages in setup and cycle times.
Faster Programming and Setup: With our intuitive CNC controls, entering new part geometries or recalling existing programs takes seconds. Because the servo motors move to exact programmed positions instantly, there is no need for the “trial and error” setup common with hydraulic machines.
Simultaneous Axis Movement: Electric machines can move multiple axes simultaneously with perfect synchronization. This capability reduces the overall bending cycle time, allowing for higher daily output compared to sequential hydraulic movements.
Cost of Ownership
While an electric bender might represent a larger upfront investment, the total cost of ownership is often much lower over the machine’s lifespan.
Energy Savings: Hydraulic pumps run continuously, wasting energy. Wonsten electric benders only draw significant power when the servo motors are actively moving the axes.
Zero Hydraulic Maintenance: No oil changes, no filter replacements, no leaking hoses, and no hazardous waste disposal. The maintenance schedule for an electric bender is vastly simplified, leading to less downtime and lower maintenance costs.
The Wonsten Commitment
We understand that every fabrication shop has unique needs. While there are still specific, ultra-heavy-wall applications where hydraulics are necessary, all-electric CNC technology is the clear choice for the vast majority of modern tube bending applications. Wonsten is committed to providing state-of-the-art electric bending solutions that help our customers improve quality, increase production, and reduce their operating costs.
