Machine park and CNC spring production
Maktel combines its spring-manufacturing experience since 1971 with CNC technologies and metal forming, machining, measurement and testing infrastructure, prioritising process stability, repeatable quality and traceability from prototype to series production.
Around 70% of Maktel’s more than 160 machines are CNC technology. The infrastructure includes CNC spring coiling and multi-axis wire-forming machines, strip-forming equipment, hydraulic presses, CNC vertical machining centres, CNC lathes, wire EDM and CNC laser cutting.
Compression, extension, torsion, wire-form and defence industry springs are produced in the 0.20–9.00 mm wire diameter range. The product range also covers flat and multi-wire springs, hose clamps and precision CNC-machined parts. Multi-axis CNC machines produce 2D and 3D wire geometries, hooks and clips built to technical drawings, with wire feed, coil diameter, pitch, length, angle and end geometries all controlled.
Heat treatment and surface finishing
Maktel determines heat treatment and stress-relieving processes based on material, geometry and working conditions. Stress relieving, thermal stabilisation, hardening and tempering are applied or managed per technical specification.
Spring-end grinding and shot peening are carried out in-house. Shot peening helps improve fatigue performance under dynamic loads. Cr+3 zinc, black oxide, nickel, phosphating, cataphoretic coating, passivation and solid-film lubricant options are evaluated against the product’s corrosion, friction and service-life requirements.
Measurement, testing and traceability
From raw material intake to final product approval, material, wire diameter, length, inner and outer diameter, force, moment, angle, geometry and critical tolerances are checked. Raw-material test equipment, spring force measurement devices, precision measuring equipment and an Ascott corrosion test chamber support verification to product and customer specification.
ERP/MRP infrastructure with QR and barcode-based traceability tracks production and product information. Measurement and test data are used in process development and in assessing the repeatability of series production.
