Miniature work with wire

Unisteel’s broad-based experience in wire form manufacturing and extensive portfolio of CNC spring coilers allow it to produce a myriad of wire formed products in all sorts of shapes and sizes designed to customers' specifications. The potential configuration opportunities are endless. Our wire formed components can be used in consumer products such as smart wearables, smart home devices and hard disk drives, to name but a few.

Added value


  • Combination of various technologies saves time
  • Fully automated processes, leading to increased reproducibility and productivity, as well as a reduction in the number of defects
  • Close collaboration from beginning to end in order to achieve optimum technical precision and the desired design

The tiny springs for smart wearables
Wire forming products are a crucial component commonly used in electronics, especially as demand for compact devices grows. From as small as 0.08mm in wire diameter, Unisteel works with both ferrous and non-ferrous materials to create the micro wire forms found in smart wearables and products with an ultra-slim profile.

Multi-component assemblies – the best of both worlds
In-mold riveting is a special technique to optimize assembly of multiple components. This revolutionary technology makes it possible to integrate wire forming and precision stamping. Unlike the traditional method, where assembly takes place in a separate process after the components have been produced, Unisteel’s in-mold riveting technology enables assembly to be designed into the production of the main components. This means multiple processes can be completed in a single stage. The process is fully automated, providing increased repeatability and productivity and reducing defects due to handling error.

Working with high-strength materials
Unisteel's wire forms can be manufactured with materials of high strength and hardness, such as SUS301SH. A high-frequency heater is introduced before the wire forming process to heat up the material prior to forming. This allows it to be formed beyond its limits without any of the fractures usually found in high-strength materials.
