Servo-Driven Positioning & Press Synchronization

 

Feed Roller Design & Surface Treatment
Feed stability relies directly on roller contact and gripping force. To accommodate different metal alloys—including stainless steel, carbon steel, copper, and aluminum—our feed rollers undergo:
High-frequency induction hardening (HRC 60 ± 2) for long-term wear resistance.
Hard chrome plating and surface polishing to prevent surface marking on delicate or pre-painted strips.
Adjustable pneumatic roller pressure to prevent slipping on oiled stock or deformation on thin gauge material.

 

Press Synchronization & Release Timing
During progressive die stamping, the feeder must release the material at the exact point of pilot pin entry. Our feeders feature configurable mechanical cam or pneumatic release interfaces to maintain alignment across multi-stage dies.

 

Quality Control & Manufacturing Standards
Every feeder undergoes rigorous quality checks prior to shipment to ensure reliable shop-floor operation:
• Mechanical Integrity: Precision grinding of feed rollers, high-capacity bearings, and rigid welded steel frames.
• Electrical Verification: Full signal validation across PLC, HMI, servo drives, safety emergency stops, and press interconnects.
• 72-Hour Pre-Shipment Run: Continuous trial operation under loaded conditions to verify thermal stability, repeatability, and timing parameters.

FAQ

 

 

Q: How accurate is an automatic servo feeder?

A: Feeder accuracy depends on material thickness, surface condition, feed length, and press operating speed. Under standard operating conditions, our servo roll feeders achieve position repeatability within +/- 0.02 mm. Precision optical encoder feedback continuously monitors roller movement to prevent incremental pitch errors during long production runs.

Q: Can your feeder integrate with my existing stamping press?

A: Yes. Our feeding systems are engineered for universal press compatibility, including mechanical, hydraulic, and pneumatic presses. They synchronize with your existing machine using standard press cam signals, programmable limit switches, or encoder feedback interfaces. We also provide custom mounting plates to match your press-side frame dimensions.

Q: What is the difference between an NC Servo Feeder and an Air Feeder?

A: An NC Servo Feeder uses an electric servo motor and PLC control, allowing operators to program variable feed lengths and speeds digitally on an HMI touchscreen. It is ideal for high-precision, multi-step, or progressive die stamping. An Air (Pneumatic) Feeder uses compressed air cylinders with mechanical stops, offering a low-cost, fixed-pitch solution for simpler, single-stage stamping jobs.

Q: How do you prevent feed rollers from marking delicate or pre-painted metal strips?

A: For sensitive materials such as polished aluminum, stainless steel, copper, or coated stock, we offer specialized roller treatments. These include chrome-plated polished surfaces, polyurethane (PU) coated rollers, and precision adjustable pneumatic roller pressure controls to ensure firm grip without surface deformation or scratches.

Q: How do I choose the correct feeder model for progressive die stamping?

A: Progressive die stamping requires precise timing between feeder release and press stroke. You should evaluate your maximum strip width, material thickness, maximum feed length, required strokes per minute (SPM), and the die pilot pin engagement window. Contact our engineering team with these parameters to receive a tailored feeder recommendation.
