Design your spring and get the price instantly
A 3D design tool for custom compression springs. Tune the dimensions, watch the quote update live, and request manufacturing — straight from the factory.
The quote appears while you design
Every dimension you change recalculates the price, weight, lead time and stock availability on the spot — no form, no email, no waiting on a salesperson to reply. And the number you see is the number you pay.
Price per quantity tier
See the unit price for 10, 100 or 1,000 pieces and the volume discount at each tier. Drag the slider and compare instantly.
Lead time already figured in
The delivery lead time shows next to the price and already accounts for any finishes and treatments you add.
Live stock
We check inventory in real time: in stock, partial or make-to-order. When pieces are ready, you get them faster and with no setup fee.
Final price, not “from”
The number on screen is what you pay. No vague figure and no surprise at the end of a negotiation.

- ✕Days (sometimes weeks) to get a quote
- ✕Uncertain price until the very end

Step by step
Five steps, all in the browser — no sign-up to start, no waiting on a salesperson.
- 1
Design your spring in 3D
Pick the type (compression, extension or torsion) and tune wire diameter, outer diameter, length and coil count. The 3D model updates in real time.
The drawing reacts to every number: you see instantly how diameter, coils and material change the spring.

Get an instant quote
Estimated price per quantity tier and lead time appear automatically on every change — no waiting for a quote.
The pricing engine runs right in your browser: material, labor and volume enter the calculation in milliseconds.
- 3
Validate the design
We check the safe limits (spring index, shear stress, solid height) and show whether your spring is within recommended limits.
The same checks an engineer would run: if something falls outside the safe range, we point out what and why.

Add to cart and request
Collect your springs in the cart and hit Request Manufacturing. The factory confirms the final price and lead time.
One order can hold several different springs; each keeps the exact spec you designed.

Production and delivery
We manufacture exactly your spec in music wire, stainless, chrome silicon and more, and ship it to you.
You track the order status from acceptance to shipment — no phone call needed to find out.
The fastest way to buy a custom spring
The same spring, two paths. Compare how it works here versus a traditional supplier.
While you wait for another supplier to reply with a quote, we've already produced and shipped your order — on its way to you.
Frequently asked questions
Is the quoted price the final price?
The number shown is a firm quote based on your spec and chosen quantity. When you request manufacturing, the factory confirms the final price and lead time — usually identical to what you saw.
Do I need to know spring math to use it?
No. You enter the dimensions you need and we handle the engineering: we validate spring index, stress and solid height and warn you if anything falls outside the recommended limits.
Can I order just a few pieces?
Yes. You see the price for any quantity — from a handful to thousands — and the volume discount at each tier, so you can decide what's worth it.
What materials do you manufacture in?
Music wire, stainless steel, chrome silicon and more, with surface and heat treatment options that are already built into the price and lead time.
What if my spring isn't standard?
You can attach a drawing, CAD or photo and add notes to the order. Our team reviews and confirms before producing.
