Electric Press Brake Details
Definition & Classification
Working Principle
Key Features
- High Precision
Full-electric press brakes achieve a positioning accuracy of ±0.01mm with excellent repeatability, ideal for precision sheet metal processing (e.g., 3C electronic casings, aerospace components).
- High Efficiency & Energy Saving
Full-electric models boast fast acceleration, with no-load speed exceeding 200mm/s. Servo motors only consume power on demand, ensuring low energy consumption. Electro-hydraulic press brakes offer superior stability for heavy-tonnage bending but have relatively higher energy consumption.
- Low Maintenance Cost
Full-electric press brakes have no hydraulic components; daily maintenance only requires guide rail lubrication and electrical connection inspections. Electro-hydraulic models need regular hydraulic oil and filter replacement, as well as valve and seal maintenance, leading to higher upkeep costs.
- High Automation Level
Most electric press brakes are equipped with CNC systems, enabling automatic programming, positioning, and synchronous operation. This minimizes manual intervention, boosting production efficiency and product quality.

Advantages of Roll Forming A Metal Part
There are several advantages of using roll forming for your projects:
- The roll forming process allows operations such as punching, notching, and welding to be performed in-line. Labor cost and time for secondary operations are reduced or eliminated, reducing part costs.
- Roll form tooling allows for a high degree of flexibility. A single set of roll form tools will make almost any length of the same cross-section. Multiple sets of tools for varying length parts are not required.
- It can provide better dimensional control than other competing metal forming processes.
- Repeatability is inherent in the process, allowing easier assembly of roll formed parts into your finished product, and minimizing problems due to “standard” tolerance build up.
- Roll forming is typically a higher speed process.
- Roll forming offers customers a superior surface finish. This makes roll forming an excellent option for decorative stainless steel parts or for parts requiring a finish such as anodizing or powder coating. Also, texture or pattern can be rolled into the surface during forming.
- Roll forming utilizes material more efficiently than other competing processes.
- Roll formed shapes can be developed with thinner walls than competing processes
Roll forming is a continuous process which converts sheet metal into an engineered shape using consecutive sets of mated rolls, each of which makes only incremental changes in the form. The sum of these small changes in form is a complex profile.
