Mechanical Clocks & Timers

Provides consistent torque for accurate timekeeping over extended periods. Used in mechanical clocks, industrial timers, and precision timing devices requiring reliable power without electrical sources.

Rewind mechanism

Rewind & Return Timing Mechanisms

Ensures controlled, consistent return speed in cable reels, cord retractors, and safety equipment requiring predictable retraction timing to prevent sudden spring release.

Metering device

Metering & Counting Devices

Drives mechanical counters and metering systems with stable torque, ensuring accurate measurement and registration over thousands of cycles without power variation.

Spring-driven indicator

Spring-Driven Indicators

Powers analog indicators and gauges requiring smooth, consistent pointer movement without electrical power sources. Common in aviation and industrial monitoring.

Slow-speed rewind

Slow-Speed Rewind Systems

Provides controlled, gradual retraction in applications where sudden spring release could cause damage or safety concerns. Ideal for controlled descent needs.

Industrial timing

Industrial Timing Assemblies

Used in production machinery and automation equipment requiring precise timing intervals without electronic controls. Ensures mechanical process synchronization.

Frequently Asked Questions

Quick answers to common questions about custom clock springs

Clock springs are engineered for stable torque release over extended rotation, prioritizing timing accuracy and predictable unwinding. Power springs maximize energy storage with steeper torque curves for burst operation. Clock springs deliver consistent performance in low-speed, continuous-duty cycles, while power springs excel in high-energy, rapid-release applications.
Yes, we engineer custom torque curves to match your exact load profile. Through material selection, geometry optimization, and heat treatment processes, we can create increasing, decreasing, or compensated torque characteristics. Variable thickness designs enable precise torque control throughout the unwinding cycle for specialized timing requirements.
Prototypes typically ship within 2-3 weeks after drawing approval. Production quantities depend on complexity and volume, generally 4-6 weeks for standard configurations. Rush service available for urgent projects. Lead times include engineering review, tooling setup, heat treatment, and quality inspection.
We accommodate small batch production starting from 50 pieces for prototyping and validation. Standard production runs begin at 500 pieces for cost optimization. We support both OEM volume production and small-batch custom orders for replacement parts and specialized applications.
Yes, we protect proprietary designs and technical specifications under NDA. All drawings, performance data, and application details remain confidential. We maintain strict information security protocols and can execute customer-provided NDA templates or our standard confidentiality agreement.
