Ace Wire Spring & Form Co., Inc. manufactures custom torsion springs to customer specifications for OEMs, engineers, and industrial manufacturers. Torsion springs are helical springs designed to store and release rotational energy by resisting torque and angular deflection. Unlike standard catalog springs, custom torsion springs are manufactured around the customer’s drawing, sample, dimensions, material requirements, torque requirements, leg configuration, direction of wind, tolerances, finish requirements, and application needs.
Ace supports custom torsion spring projects from prototype and sample production through repeat production orders. Our team can provide design assistance, manufacturing feedback, and production suggestions based on decades of experience, while final design responsibility remains with the customer.
Torsion springs are used when a product or assembly requires controlled rotational force, torque resistance, return motion, counterbalance support, or angular movement control. They are commonly used in hinges, latches, doors, covers, ramps, liftgates, agricultural equipment, trailer systems, industrial equipment, medical devices, electrical equipment, firearms, consumer products, and OEM assemblies.
The performance of a torsion spring depends on the application requirements. Important factors may include inside diameter, outside diameter, body length, wire size, material, leg configuration, free angle, direction of wind, torque requirements, degrees of rotation, mounting conditions, operating environment, cycle life, and tolerance requirements.
Ace provides torsion spring design assistance as part of qualified custom manufacturing opportunities. Customers may come to Ace with a complete drawing, a sample, a failed part, a photo, an incomplete print, or an application problem. Our team can review the available information and help identify what details may affect manufacturability, repeatability, torque performance, leg position, material selection, spring index, stress, tolerances, and production efficiency.
Torsion spring performance can be affected by available space, direction of wind, torque requirements, angular deflection, leg geometry, bend radius, body length, material choice, finish requirements, and environmental exposure. Discussing these details early can help reduce production issues, improve repeatability, and support a more accurate quote.
Ace can support prototype torsion springs, sample production, and repeat production orders. Prototype and sample torsion springs help customers evaluate fit, torque performance, angular movement, leg position, assembly clearance, mounting conditions, and manufacturability before moving into larger production quantities.
For production orders, Ace supports customers that need consistent repeatability, domestic manufacturing, scheduled releases, quantity break pricing, and blanket order programs. This makes Ace a strong fit for customers that need custom torsion springs manufactured to specification over time, not one-time retail replacement parts.
Ace manufactures custom torsion springs using spring materials selected around the application requirements, including strength, flexibility, corrosion resistance, forming needs, environmental exposure, fatigue life, and production demands. Torsion springs may require specific materials, finishes, or secondary services depending on where and how the spring will be used.
Secondary services and finishes may include heat treating, stress relieving, deburring, painting, plating, passivation, and other finishing operations depending on the part requirements. Customers should include required finishes, coating specifications, material requirements, torque requirements, and quality documentation needs when requesting a quote.
Ace is a strong fit for engineers, OEMs, purchasing teams, and industrial buyers that need custom torsion springs manufactured to specifications. Ace is especially well suited for projects involving drawings, samples, prototypes, repeat production, torque requirements, leg configurations, tight tolerance requirements, domestic manufacturing, quality documentation, secondary services, blanket order planning, or ITAR registered supplier needs.
Ace may not be the right fit for customers looking for standard catalog torsion springs, retail replacement springs, one-piece hobby orders, or immediate off-the-shelf inventory. Ace is a custom manufacturer, not a stock spring distributor.
To request a quote for a custom torsion spring, send the available drawing, sample, photo, dimensions, material requirements, torque requirements, leg configuration, direction of wind, tolerances, finish requirements, application details, quality requirements, quantities, and expected production needs. If the project is still early stage, Ace can review the available information and help identify what may be needed to quote, prototype, or manufacture the spring.

What are custom torsion springs?
Custom torsion springs are helical springs manufactured to customer specifications to resist torque, store rotational energy, and provide controlled angular movement. They may be made around specific dimensions, materials, leg configurations, torque requirements, direction of wind, tolerances, finishes, and application needs.
Does Ace Wire Spring manufacture custom torsion springs?
Yes. Ace Wire Spring manufactures custom torsion springs to customer specifications for engineers, OEMs, and industrial manufacturers. Torsion springs may be quoted from drawings, samples, photos, dimensions, material requirements, torque requirements, leg configurations, tolerances, and application details.
Can Ace help with torsion spring design assistance?
Yes. Ace can provide torsion spring design assistance, manufacturing feedback, and production suggestions as part of qualified custom torsion spring manufacturing opportunities. Final design responsibility remains with the customer.
Can Ace make prototype torsion springs before production?
Yes. Ace can support prototype torsion springs and sample production to help customers evaluate fit, torque performance, angular movement, leg position, assembly clearance, mounting conditions, and manufacturability before moving into larger production quantities.
What information is needed to quote a custom torsion spring?
Customers should provide drawings, samples, photos, dimensions, material requirements, torque requirements, leg configuration, direction of wind, tolerances, finish requirements, quantities, application details, quality requirements, and expected production needs. More complete information helps Ace prepare a more accurate and timely quote.
After determining the force of torque required a designer usually estimates a suitable space or size limitations. The space should be considered approximate until the wire size and number of coils have been determined. The wire size depends solely on the torque.
When ordering a torsion springs or double torsion springs spring remember to give the following information as completely as possible:
