Choosing the right component supplier is key to operational continuity on assembly lines. Springs and their production is a field requiring the highest engineering precision.
Spring production is a multi-stage technological process consisting of forming steel wire on numerical CNC bending machines, and then subjecting it to heat and surface treatment, which gives the part its final elastic and strength properties.
See what the series production of these elements looks like from the inside out.
From CAD design to CNC bending
Before series production starts, engineers analyze the documentation in CAD/CAM systems. We use high-grade wires in diameters ranging from 0.2 to 18.5 mm, maintaining a rigorous tolerance of ±0.01 mm.
For your application, this means a perfect fit of the compression or extension spring into the machine socket, completely eliminating the need for costly secondary machining. Plastic forming on CNC automatic machines is a guarantee of dimensional repeatability, even with multi-million batches.
Heat and anti-corrosion treatment
The formed spring then goes to an oven for stress relieving – this process removes internal stresses in the material. The next step is surface protection. On our automated line, we perform zinc flake coating, which significantly extends the product's life cycle in aggressive environments (e.g., in automotive), while maintaining sustainability standards and the REACH and RoHS environmental directives.
Summary
A properly optimized, multi-stage series production of springs is a guarantee of on-time deliveries and zero defects in your supply chain.
