In modern metal stamping and coil processing industries, achieving precise, stable, and high-speed material feeding is essential for maintaining production efficiency. The servo feeder has become the core of automated feeding systems, replacing traditional pneumatic and mechanical feeders with superior accuracy and flexibility. Equipped with advanced servo motors and intelligent control systems, it ensures consistent performance in demanding production environments such as automotive parts, home appliances, and metal components manufacturing.Get more news about servo feeder,you can vist our website!

Function and working principle of a servo feeder

The servo feeder operates through a closed-loop control system that synchronizes feeding actions with the press or stamping machine. The servo motor drives the feed rollers, delivering precise movement based on the set feeding length and speed parameters.
Each feed cycle is digitally controlled—operators can easily input or modify feed lengths on the control panel. Thanks to the closed-loop feedback, the deviation between the set and actual feeding length is maintained within ±0.03 mm, ensuring unmatched accuracy in every stroke.

The machine’s multi-stage feeding function allows up to 10 different feeding lengths, with each group supporting up to 999 feeding cycles. This design makes it ideal for complex production processes that require varied feed lengths, reducing setup time and improving production flexibility.

During each press stroke, the servo feeder automatically releases the material in synchronization with the press cam signal. A simple adjustment for material thickness allows for quick and accurate setup of the release angle, improving compatibility across different metal sheets.

Technical features and advantages of servo feeder

1. Exceptional feeding accuracy–The closed-loop servo control ensures the material is positioned with micrometer precision, reducing waste and ensuring part consistency.
2. Multi-length programming–The ability to input multiple feeding lengths allows seamless production of components with varying dimensions without changing the setup.
3. Efficient release mechanism–By matching the press cam signal, the system automatically relaxes the material, ensuring smooth feeding without tension or deformation.
4. Easy operation and setup–Feeding length and speed can be directly input on the digital control panel, making adjustments quick and intuitive for operators.
5. Durable feeding rollers–The feed rollers are made of hollow-core, hard-chrome plated steel (HRC60°) for lightweight, low inertia operation. They are wear-resistant and long-lasting, ensuring stability even under high-speed conditions.
6. Compact and reliable structure–The streamlined mechanical design allows easy installation, space-saving layout, and long-term stability.

Application range of servo feeder

The servo feeder is widely used in automotive stamping lines, electrical component production, home appliance parts, and general sheet metal fabrication. It is compatible with a variety of materials including stainless steel, carbon steel, copper, and aluminum.
Whether integrated with a press line, cut-to-length line, or coil blanking system, the servo feeder provides efficient and precise coil handling, enabling continuous and automated production. Its flexibility also makes it suitable for progressive die stamping and high-mix, low-volume production scenarios.
