Overview
Spiral springs also known as constant force spring or Clock spring. This type of spring is usually a coiled ribbon of spring steel used for functions such as counter balancing, retrieving, maintaining constant loads, transmitting motion, and clamping. It requires nearly the same force, no matter how long the extension. Spiral Springs, produced from flat steel, are characterized by the requirement that their coils do not touch during operation. This type of spring will exert a rotational torque, usually through 360 Degree rotation or less. The inner end of the spring is typically bent to attach to an arbor or hub. The outer end is then attached to the object that is rotating or utilizing the torque of the spring.
Material
- C80 Grade cold rolled annealed steel strips
- C75 Grade cold rolled annealed steel strips
- 304 Grade stainless steel strips
Finish
Can be supplied in various plating
Manufacturing Process
Spiral Springs are manufactured on imported CNC Spring forming Machines or on SPM to maintain its criticality in applications.
Testing & Certification Process
Each spring manufactured goes through a series of rigorous tests conducted on in house testing facilities such as Computerized Load Testing, UTS Testing, Torsion testing, Profile Projector amongst others. All springs are supplied with ROHS raw material compliant report.
PRODUCT APPLICATIONS
Spiral springs are used in electrical motor contact brushes that require short rotation (less than 360 degrees of rotation). They obtain a large amount of torque through a small amount of rotation. They are also used in Seat Belts, Door Handles, Door Closers, Car Windows, Motors, Point of Purchase Displays, Counter balances, Office Equipment’s, Carbon Brush, Clocks, Toys, Rewind Devices, among others.
