Designed for manufacturing heavy-duty double torsion springs, agricultural tine springs, large extension springs, automotive seat torsion springs, industrial torsion springs, and other large custom spring products.
The 12100 Heavy-Duty CNC Camless Spring Forming Machine is engineered for manufacturers producing large, high-load, and structurally complex spring products from Ø4.0 mm to Ø10.0 mm wire.
Equipped with a powerful 12-axis servo-controlled system, four pairs of wire feed wheels, an independent wire rotation servo, and eight high-power forming slides, the 12100 provides the forming force, stability, and flexibility required for demanding large-spring production.
Compared with spring machines designed for smaller wire diameters, the 12100 offers stronger feeding power, greater forming torque, and better control of springback, leg angles, hook shapes, and special spring ends.
The 12100 is optimized for spring manufacturers producing large products that require high forming force and precise control of complex geometries.
Typical products include:
Heavy-Duty Double Torsion Springs
Agricultural Tine Springs
Large Extension Springs
Automotive Seat Torsion Springs
Heavy-Duty Torsion Springs
Extension Springs with Custom Hooks
Custom-Shaped Wire Springs
Industrial Spring Clips
Multi-Strand Wire Double Torsion Springs
Heavy-Duty Compression Springs with Formed Ends
These products are commonly used in automotive seating systems, agricultural machinery, industrial equipment, construction machinery, heavy hardware, and mechanical assemblies.
Large double torsion springs require accurate control of two coil bodies, the central connecting section, leg angles, and left-right symmetry.
The 12100 uses independent servo-controlled forming movements to help manufacturers control:
Coil diameter consistency
Center spacing
Coil symmetry
Leg length and angle
Forming sequence
Springback compensation
This makes the machine especially suitable for producing large double torsion springs used in industrial mechanisms, agricultural equipment, and heavy mechanical assemblies.
Agricultural tine springs are subjected to repeated impact, vibration, and high working loads. Their production requires strong wire feeding, stable coiling, and accurate forming of long spring arms.
The 12100 is suitable for manufacturing agricultural spring products such as:
Cultivator tine springs
Harrow tine springs
Hay rake springs
Pickup tine springs
Seed drill springs
Agricultural return springs
Its heavy-duty servo configuration provides the power required to form thick spring wire while maintaining stable product dimensions.
Large extension springs often require strong coil bodies and precisely formed end hooks.
The 12100 can be used to manufacture:
Large industrial extension springs
Agricultural extension springs
Machinery return springs
Door and gate extension springs
Equipment tension springs
Extension springs with custom hooks
The camless forming system allows operators to program different hook shapes, end lengths, and spring-body dimensions according to customer drawings.
Automotive seat torsion springs require consistent torque, precise leg positioning, and reliable repeatability.
Typical applications include:
Seat adjustment mechanisms
Seat recliner systems
Seat locking assemblies
Headrest mechanisms
Folding seat systems
Automotive interior hardware
The 12100 provides multi-axis control for forming spring legs, coil bodies, and complex end geometries used in automotive seating components.
Heavy-duty torsion springs are widely used in industrial machinery, construction equipment, agricultural systems, and mechanical assemblies.
The machine is suitable for producing:
Large single torsion springs
Industrial return torsion springs
Heavy door torsion springs
Machinery torsion springs
Lever mechanism springs
Custom-angle torsion springs
Independent servo control helps maintain accurate coil geometry and leg positioning throughout production.
Multi-strand wire double torsion springs require greater forming power and careful control of the wire bundle during feeding and forming.
The 12100's heavy-duty feeding system and high-power forming slides make it suitable for these demanding spring structures.
Key production requirements include:
Stable multi-strand feeding
Consistent coil formation
Accurate dual-coil symmetry
Controlled center spacing
Precise arm and leg positioning
These springs are often used in high-load mechanisms where increased strength and fatigue resistance are required.
Some large compression springs require formed ends, extended legs, hooks, or special terminal structures instead of standard closed ends.
The 12100 can manufacture heavy compression springs with:
Formed wire ends
Extended end sections
Bent terminal legs
Custom hook ends
Variable pitch
Conical or irregular coil bodies
This flexibility makes the machine suitable for custom industrial spring applications that cannot be produced efficiently on standard compression spring coiling machines.
Processing wire up to Ø10.0 mm creates significantly greater forming resistance than small-wire spring production.
Large spring manufacturing requires:
Higher wire feeding force
Greater servo torque
Stronger wire gripping
More rigid machine construction
Stable tool positioning
Better springback compensation
Accurate multi-axis synchronization
Reliable continuous production
The 12100 is designed specifically to meet these heavy-duty production requirements.
The 12100 combines multiple high-power servo axes to control the complete spring-forming process.
Key servo configurations include:
15 kW wire feeding servo
5.5 kW wire rotation servo
1.5 kW mandrel rotation servo
2.7 kW spinner servo
Eight 5.5 kW forming slide servos
This architecture allows the machine to coordinate feeding, coiling, rotation, leg forming, hook forming, end shaping, and cutting according to the programmed production sequence.
