Flat Spiral Spring

Custom Flat Spiral Spring Supplier and Manufacturer

The flat spiral spring also known as a clockwork spring is a spring with torque; Under the action of torque, the spring material produces bending elastic deformation, which makes the spring produce torsion in the plane. The deformation angle is proportional to the torque. Flat spiral springs are used in many fields and industries. For example: toy, lock, rice cooker, electric toy; dog leash; safety belt; industrial tool; automobile starter; Automobile balance devices.

  • According to the fixing ways: ① hinge type, ② pin type, ③ V-shaped, and ④ lining type.

The fixing method is as follows:

1. Install the spring into the C-type snap ring first (the outer diameter of the C-ring is smaller than the installation space);

2. Install the installed c-buckle and spring into the clock;

3. Take out the C buckle with a clip or small tweezers.

Sampling usually takes about 5~7 days. For large goods, it usually takes 7-15 days according to the quantity.
