Why We Manufacture Even a Single Piece
We set no minimum order quantity for custom spring manufacturing. We produce from a single piece — typically for three situations: product development and testing, where an engineer needs a functional prototype before launching serial production; machine repair, where a discontinued or out-of-stock spring needs replacing; and concept verification before ordering a larger batch. A single piece is produced on the same CNC bending automats used for serial production, so the prototype matches what would be produced in series.
Development & Testing
Functional prototype before launching serial production
Machine Repair
Replacement for discontinued or out-of-stock parts
Concept Verification
Verify function with a prototype before ordering in volume
What We Need to Start Production
A drawing in PDF, DXF or STEP format is sufficient. If you don't have a drawing, a photo of the sample with dimensions works too — outer diameter, wire diameter, length and number of coils for springs, or a dimensioned sketch for formed parts. If you're unsure of the exact specification, we provide free, non-binding technical consultation.

Materials Used for Prototypes
We standardly use spring steel per EN 10270-1 and EN 10270-3, and stainless steel 1.4310 and 1.4568. For special conditions — corrosive environments, high temperatures, or electrical conductivity requirements — we also offer bronze, brass or Inconel. We recommend the appropriate material based on the operating conditions the spring or part will face.
| Material | Standard / Grade | Typical Use |
|---|---|---|
| Spring steel | EN 10270-1, EN 10270-3 | Standard applications, universal |
| Stainless steel | 1.4310, 1.4568 | Corrosive environments, food industry |
| Bronze | CuSn8P | Electrical conductivity, sliding surfaces |
| Brass | CuZn36 | Decorative parts, mild corrosion |
| Inconel | 2.4856 (IN 625) | High temperatures, aggressive media |
How Long Prototype Production Takes
After receiving your documents, we respond within 24 hours with a price quote, delivery date, and material recommendation. The prototype itself is typically delivered within 3–5 business days of order confirmation; express deadlines can be arranged individually. Every piece undergoes dimensional and functional inspection under our ISO 9001 certified quality system.
Frequently Asked Questions
What's the minimum quantity for custom spring manufacturing?
From one piece — no minimum order is set.
Can you manufacture a spring from a sample without a drawing?
Yes, from a photo of the sample with dimensions we measure and reproduce the original.
How long does prototype production take?
Typically 3–5 business days from order confirmation.
Is technical consultation free?
Yes, consultation on material and specification is always free and non-binding.
Do you ship prototypes internationally?
Yes, regularly to Slovakia, Austria, Germany and Poland.
