Custom Clock Type Spiral Spring Manufacturing
Introduction
Clock type spiral springs, often called mainsprings, are designed to store energy in a compact spiral coil and release it steadily as controlled torque. Durga Spring is a custom clock type spiral spring manufacturer serving OEMs, repair industries, and mechanism designers who require smooth winding, predictable return, and consistent torque across cycles. These springs are used in timers, retractors, rewind systems, compact actuators, and precision mechanical assemblies where stable energy delivery matters. By controlling strip quality, coil geometry, and end engagement, we help ensure your mechanism runs smoothly with repeatable performance from batch to batch.
How We Produce Custom Mainsprings Made to Drawing
A clock type spiral spring is only reliable when dimensions and torque behavior match the housing and working travel. We build consistent outcomes using these production controls:
Strip Precision and Edge Quality: Controlled thickness, width, and edge finishing help reduce stress points, improving fatigue life and smooth winding.
Coil Geometry Control: Inner diameter, outer diameter, number of turns, and winding direction are maintained to fit the drum or housing without rubbing or binding.
End Forming and Locking: Inner and outer ends are formed as required (hook, slot, tab, loop) to ensure secure engagement and stable torque transfer during operation.
This ensures custom clock type spiral springs that assemble properly and deliver predictable torque behavior.

Key Specifications to Share for Custom Development
Housing constraints including available outer diameter, inner diameter, and clearance limits.
Required working angle, number of turns, and desired torque behavior across travel.
Winding direction and end engagement style matching your drum or shaft features.
Cycle life expectation and operating environment, including humidity or corrosive exposure.
Drawing, sample, or assembly reference to ensure fit repeatability in production.
Supporting Precision Mechanisms with Consistent Torque
Choosing a custom clock type spiral spring manufacturer is about achieving stable performance within tight packaging constraints. Durga Spring supports engineering teams by aligning spring geometry with housing design, return travel, and engagement method, helping reduce assembly issues and performance variation. Whether the requirement is for a compact timer spring, a smooth rewind spring, or a reliable mainspring for a mechanical system, our focus remains on consistent strip selection, repeatable winding, and secure end forming so your mechanism performs reliably over its intended cycles.
Maintenance & Safety Tips — Reliable Operation
ChecklistDurga Spring
Fit & Function
Verify the spring coil clears the housing throughout travel to prevent rubbing, heat build-up, and early fatigue.
Ensure the inner and outer ends are fully seated in their slots or hooks to avoid slip and inconsistent torque.
Operate within the designed winding range to reduce overstress and set formation in the mainspring.
Handling & Safety
Use proper fixtures and protective gloves during installation because the spring stores energy and can release suddenly if unsecured.
Inspect for edge nicks, corrosion, or distortion during servicing, as these can reduce fatigue life significantly.
Keep the spring away from abrasive dust and moisture, and protect surfaces if used in humid or corrosive environments.
FAQs about Custom Clock Type Spiral Springs
Q1
What is a clock type spiral spring or mainspring?
It is a flat strip spring coiled into a spiral that stores energy when wound and releases it as controlled torque. It is commonly used in timers, retractors, and compact rewind mechanisms.
Q2
What information is needed to manufacture a custom clock spring?
Share housing OD/ID limits, working angle, required torque behavior, winding direction, end style, and expected cycle life. A drawing or sample helps confirm fit and engagement details.
Q3
Can you make spiral springs with different end formations?
Yes. We can form inner and outer ends as hooks, slots, tabs, loops, or other engagement styles based on your drum or housing design to ensure secure torque transfer.
Q4
How do you ensure consistent torque in clock type spiral springs?
Consistency comes from controlled strip thickness and width, accurate coil geometry, proper end engagement, and producing within design limits so the spring winds and returns smoothly across its working travel.
Q5
How can I request a quote for a custom mainspring?
