FAQ

Q: What are flat spiral springs used for?

A: Flat spiral springs, with their unique design and functional characteristics, play a crucial role in numerous industries and devices. From electrical switches to surgical instruments, these springs offer a versatile solution for applications requiring controlled deflection, force generation, and energy storage.

Q: What is the difference between flat spring and round spring?

A: Flat wire springs are more resistant to twisting and are more stable than round wire springs. The added stability of these components can significantly improve the performance and reliability of the end items in which they are used.

Q: What makes a spring more powerful?

A: Wire Diameter
Thicker wire usually produces a stiffer spring and can withstand heavier loads and can also increase the springs resilience to fatigue although thicker wires can reduce the number of coils accommodated which affects energy stored.

Q: What is the best steel for flat springs?

A: Most flat springs come in either carbon steel or stainless steel. A stainless steel flat metal leaf spring is one of the strongest springs available, with excellent hardness and heat resistance. Most manufacturing facility managers have a basic idea of the type of spring required to meet production needs.

Q: How to make a torsion spring stronger?

A: If you make the wire diameter larger, you will make the spring stronger and if you make it smaller, you will make it weaker. This is because, by making the wire diameter larger, you are also making the spring's coils tighter which reduces the spring index.
