GCH Series | Dual Servo Feeder for High-Speed Presses
High Speed Double Servo Feeder Machine
Henli GCH high speed double servo feeder is built for thin silicon steel, stator and rotor lamination stamping, long feeding pitch, wide high-speed press layouts and buyers comparing a dual servo feeder or double stage servo feeding machine for coordinated feed-and-pull control.
Why Double Servo
Use GCH when the line needs coordinated high-speed strip control
A standard servo feeder can solve many general stamping applications. GCH is selected when thin electrical steel, wide strip, long pitch, release timing and press-side coordination become the real engineering problem. Buyers may describe this need as a dual servo feeder, double stage servo feeding machine or high speed double servo feeder for a stamping press.
- Thin silicon steel strip for stator and rotor lamination stamping.
- Wide-bed high-speed press lines where strip stability and release timing matter.
- Projects where one GCH feeds material into the press and another GCH may pull stamped strip out after the die.
- Mold change work where touchscreen stroke-space setting can reduce mechanical gear-change dependence.
Application Fit
Built for motor lamination press feeding applications
For motor lamination projects, the buyer question is specific: which feeder can handle thin silicon steel, long pitch, wide press layouts and demanding release timing without being treated as a generic NC servo feeder?
EV drive motor cores
For stator and rotor lamination lines where thin electrical steel, long pitch and press synchronization decide production stability.
Compressor motor cores
For air-conditioner and refrigerator compressor motor lamination production, including new lines and retrofit projects.
BLDC, servo and industrial motors
For motor core production that requires reliable strip control in high-speed progressive die stamping.
Press feeding application
Shows GCH feeder integration near the press for high-speed stamping production.
Line overview
Good reference for buyers checking front-end feeding, press access and shop-floor layout.
Press-side layout
Side view of the double servo feeder, decoiler and high-speed press relationship.
Line Configuration
Where GCH fits in a complete high-speed motor lamination line
GCH is not the whole motor lamination stamping line. It is the high-speed double servo feeder module used around the press: one unit may feed thin silicon steel into the die, and another unit may pull stamped strip or skeleton scrap out before downstream scrap handling.
This product page keeps the focus on the GCH feeder. The complete high speed motor lamination stamping line, including decoiler, head/tail cutting and welding, S-loop leveler, press and scrap chopper, should be specified as a full line project.
Line equipment set
Shows line modules prepared before installation, useful for discussing GCH position in the layout.
S-loop pairing
Shows the leveler and feeder relationship before the strip enters the high-speed press.
Factory layout
Use this view when checking decoiler, leveler, GCH feeder, press access and downstream space.
Model Selection
GCH model difference depends on strip width, pitch and press layout
The photos show different GCH bodies and press-side installations. For quotation, Henli should confirm whether the unit is used before the press for feeding, after the press for pulling, or as part of a one-feed-one-pull layout with coordinated control. This is more accurate than selecting only by the words double servo, dual servo or double stage.

Setup Efficiency
Touchscreen stroke-space, feed angle and release angle setup
The current Henli product information highlights touchscreen control for stroke-space, feed angle and release angle. This matters when multiple molds are used because the operator can adjust parameters without relying only on private gears for different mold pitches.
Stroke-space setting
Set feeding stroke from the control interface when mold pitch changes.
Feed and release angle
Adjust timing around press motion and die release requirements.
Repeatable setup
Useful for high-volume motor core lines where mold-change records and timing consistency matter.

Comparison
How to explain GCH against single-servo and NC servo feeders
Compared with GCD single servo
The GCD high speed servo feed machine is better for general high-speed stamping. Choose GCH when thin silicon steel, motor core stamping, wide-bed press, long pitch or feeding/pulling coordination becomes the engineering problem.
Compared with NC servo feeder
NC servo feeder covers broader press automation, including power press, hydraulic press, laser, shearing and general coil feeding. GCH is a specialized high-speed feeder for motor lamination and demanding press synchronization.
Compared with gear feeder
High-speed gear feeders can suit short-pitch ultra-high-speed stamping. GCH is more attractive when servo parameter setting, long pitch and mold-change flexibility are part of the buyer requirement.
Quote Preparation
For GCH feeder selection, quotation starts with die and press data
For manufacturer, supplier, factory or price requests, GCH quotation should be built from press, die and material data rather than a generic model name.
Material and coil
Silicon steel grade, strip thickness, strip width, coil weight, coil ID/OD and whether surface protection is required.
Press and mold
Press brand/model, bed size, strokes per minute, feeding pitch, die release angle, mold drawing and mold change frequency.
Line configuration
Decoiler type, head/tail cutting and welding need, S-loop leveler need, feeding-side or pulling-side GCH role, one-feed-one-pull requirement, scrap chopper need and available floor layout.
Supplier and price context
Confirm whether the quote is for the GCH feeder only or for a complete decoiler, leveler, feeder and scrap-handling line.

FAQ
High speed double servo feeder FAQs
What is the difference between a single servo feeder and a double servo feeder?
A single servo feeder is usually selected for general high-speed press feeding where servo pitch control and release timing are enough. A double servo feeder is selected when the line needs more coordinated high-speed control, such as thin silicon steel, long pitch, wide material or feeding/pulling coordination around a high-speed press.
Is double servo the same thing as one-feed-one-pull?
No. Double servo describes the feeder control architecture, while one-feed-one-pull describes a production layout. In a motor lamination line, one GCH may feed the strip into the die and another GCH may pull stamped strip out after the press, but a single double servo feeder should not be described as the whole one-feed-one-pull system.
Can GCH be used after the press as a pulling feeder?
Yes, in suitable high-speed lamination layouts a GCH-type feeder can be selected for the downstream pulling role. The final layout should be confirmed against die structure, strip path, press timing and downstream scrap handling.
Which industries usually need a GCH double servo feeder?
Typical applications include EV drive motor cores, compressor motor cores, servo motor laminations, BLDC motor laminations and industrial motor stator or rotor core production. These lines often use thin silicon steel and high-speed presses.
What line equipment may be used with this feeder?
A complete high-speed motor lamination line may include a double-head decoiler, head/tail cutting and welding unit, S-loop high-speed leveler, feeding-side GCH, high-speed press, pulling-side GCH and high-speed scrap chopper. This GCH product page focuses on the feeder module, not the entire production line.
Why do some buyers call it a double stage servo feeding machine?
Some buyers use double stage servo feeding machine to describe a feeder with two-servo control or a line where feeding and pulling roles are coordinated around the press. For GCH selection, Henli checks the actual strip path, die timing and feeder role instead of relying only on the search term.
Can Henli quote the GCH as a feeder supplier or a complete line supplier?
Yes. Henli can review a GCH feeder-only request or a complete high-speed line request with decoiler, S-loop leveler, press-side feeder, downstream pulling feeder and scrap handling. The quote should state which equipment is included.
What information is needed before quotation?
Please provide silicon steel grade, material thickness, strip width, coil dimensions, feeding pitch, press model, strokes per minute, die release angle, mold drawing, feeder role, one-feed-one-pull requirement, downstream scrap handling and available layout space.
