  • Chemical composition verification
  • Mechanical properties control
  • Wire geometry measurement
• Production preparation:
  • Development of control programs
  • Equipment setup
  • Tooling manufacturing
• Production process:
  • Wire straightening and calibration
  • Product forming
  • Heat treatment
  • Coating application

Specialized Materials and Processing Methods

Manufacturing parts using 2D bending requires the correct selection of materials, taking into account further operating conditions. For the production of stopper springs and retainer brackets, special grades of spring steels are used, which provide an optimal combination of strength, elasticity, and durability. High-precision formation of hooks and cotter pins is complemented by special heat treatment, which gives the products the necessary complex of mechanical properties.

Materials used and their features:

• Spring steels:
  • EN10270-DH – high elasticity and fatigue strength
  • EN10270-SH – resistance to dynamic loads
  • EN10270-SM – for light industry
• Stainless steels:
  • AISI 302, AISI 324 – corrosion resistance
  • AISI 301, SUS 301 – for food industry
  • AISI 304 – heat-resistant properties

Protective springs and other parts undergo additional heat treatment to stabilize properties. After forming, the spring undergoes special thermomechanical treatment, ensuring the preservation of the specified geometry under operational loads.

High-Precision Measurements and Quality Control

The production of complex spatial structures is accompanied by constant monitoring of geometric parameters. Each product, from simple to complex, passes through a multi-stage quality control system using modern measuring equipment.
