Wire Springs FAQs
What is a wire spring?
Our Lesjöfors wire springs store and release energy due to their shape or tightly coiled makeup. Depending on the type of spring, when force is applied, it will try to work against this force by either resisting compression, twisting, or extending.
What industries are wire springs commonly used in?
Our wire springs are used in a wide variety of industries including:
– Automotive
– Aerospace
– Medical
– Electronics
– Construction
What is the lead time for stock springs?
Standard shipping can take anywhere up to 10 days for stock springs. Our express shipping option will take between 3-5 days.
What materials are our wire springs made from?
Our Lesjöfors wire springs are available in both unalloyed steel and stainless steel, suitable for various applications and environments. We pride ourselves on only using materials of the highest quality, with unalloyed steel being a cost-effective option for mild environments, and stainless steel being ideal for high temperature, outdoor applications.
Do Metrol offer custom spring designs?
Yes, we can design custom wire springs made just for your applications needs. A perfect option for those requiring bespoke features for their spring solutions.
How do I choose the right wire spring for my application?
It is first important to consider what load type your application will be putting on the spring. Is it going to compress, exert a pull force, or rotate? After determining this, you can then use the drop-down features to select your desired material, required force, and measurements.
What wire springs do Metrol offer?
We offer a wide range of stock and custom Lesjöfors spring products.
Compression springs – a standard wire spring made up of a coiled wire that resists compression, commonly found in pens.
Tension springs – resists stretching when the application pulls either ends. Often found on trampolines.
Torsion springs – each end will twist in opposite directions. Commonly used in clothing pegs.
Die springs – a type of compression spring designed for heavy duty applications such as metal presses.
Conical springs – a cone shaped spring which enables it to compress into itself, often used in battery holders.
Wave springs – a flat wired wave-like shape, perfect for space saving applications such as medical devices.
Power springs – a flat wired tight spiral shape which unwinds when force is applied and retracts back to its original state on its own, typically used in tape measures.
Clock springs – a flat wired spiral shape that aids movement when wound up, a common application is a music box.
Constant torque springs – provides a continuous rotational force, used in many retraction units for seatbelts.
Disc springs– often stacked in a series or parallel in order to achieve high forces in a compact design, typically used in car brakes.
Do Metrol offer springs in super alloys?
Yes, though not part of our standard stock range. Metrol, as part of the Lesjöfors group can manufacture bespoke springs made of special alloys such as Inconel, Elgiloy, Hastelloy and more. Please contact us to discuss further.
