Every component delay in the supply chain can halt an assembly line worth millions. Mass-scale custom spring production requires a precise balance between machine efficiency and rigorous control of technical parameters.
An effective production process is an integrated system based on CNC automation and ISO/IATF standards, which allows for reducing lead time to a minimum while maintaining full geometric repeatability of every single piece.
How does technology shorten Lead Time?
The key to success in mass production is the elimination of "bottlenecks." In the case of springs, the most important parameter is Lead Time - the time from technical drawing approval to the shipment of the finished product.
We use modern CNC bending machines that allow for lightning-fast changeovers (SMED method), which reduces production setup time from hours to minutes.
Vision systems and real-time control
To ensure near 0% rejects during a production run of 50,000 units, we use vision systems integrated with the production line. High-resolution cameras measure every spring on the fly.
If a wire parameter (e.g., diameter 0.2–18.5 mm) deviates from the tolerance by ±0.01 mm, the machine automatically corrects the settings or rejects the defective element without interrupting the cycle.
Case Study: We produced 50,000 springs for a client in 7 days
- Problem: An automotive industry client reported a sudden demand for 50,000 compression springs due to the failure of a previous supplier.
- Solution: Thanks to our own warehouse of wire compliant with the EN 10270 standard and the use of two-shift operation of CNC automatons, we launched production within 24 hours of the inquiry.
- Effect: The entire order was delivered to the plant in 7 days. A quality audit confirmed full compliance with the IATF 16949 standard.

Common mistakes and myths
- Myth: Fast production means lower quality. In a modern machinery park, it is precisely the high speed of work that forces the highest process stability.
- Mistake: Failure to verify material certificates. Using wires without certifications risks spring breakage. At Metalpol, we only use steels compliant with REACH and RoHS.
- Mistake: Ignoring logistics costs. Our location in SSE Mielec allows for rapid distribution across Poland and Europe, reducing the Total Cost of Ownership (TCO).

FAQ
Can lead time be shortened for specific materials?
Yes, we maintain a wide stock of standard and acid-resistant wires, which eliminates the waiting time for raw materials.
Which standards are crucial in the automotive industry?
The absolute foundation is IATF 16949 certification and compliance with the EN 13906 dimensional standard.
Do you produce springs based on 3D models?
Yes, our design office works with CAD/CAM systems, allowing for production directly from the client's digital files.
