Engineering Springs: A Basic Introduction

What are technical springs?

Engineering springs are coil springs that are used in a variety of applications to store and release mechanical energy. They are used in various industries including automotive, mechanical engineering, electronics and medical technology. Engineering springs can be manufactured in various shapes and sizes to meet the specific needs of your application.

Why are technical springs important?

Engineered springs play a crucial role in many mechanical systems. They serve to absorb forces, dampen vibrations, enable movements and hold components together. Without technical springs, many devices and machines would not be able to function properly. Therefore, it is crucial to use high quality engineered springs that meet the specific needs of an application.

The importance of high quality spring steel

Oil Tempered or Untempered Wire: Which is Better?

In the production of technical springs, high-quality spring steel is used, which was specially developed for the requirements of milling technology. Depending on the design of the spring, oil-hardened or unhardened wire can be used. Both options have their own advantages and disadvantages.

The oil-hardened wire is annealed without stress immediately after the winding process. This gives the spring high strength and resilience. Springs made from unhardened wire are tempered after winding, which also gives them high strength. In both cases the steel meets the required quality properties.

Heat treatment and grinding of springs

When winding technical springs, internal tensions arise in the spring steel. These tensions must be released again through heat treatment with heating. Heat treatment increases the strength and durability of the springs.

Some spring designs require grinding on one or both ends. Grinding is carried out in special computer-controlled grinding machines for springs. This ensures a uniform surface and exact length and angle tolerance.

The production process of CNC machined springs

Winding feathers

The production process of CNC milled springs begins with winding the spring steel on computer-controlled winding machines. Winding involves shaping the springs into the desired shape, although the diameter and number of coils can vary depending on the requirements of the application. Wrapping is done cold, allowing good flexibility and adaptability.

Heat treatment and grinding

After the winding process, the springs undergo a heat treatment to release the internal stresses in the spring steel. This increases the strength and durability of the springs. If necessary, the springs are then sanded to ensure a uniform surface and precise dimensions.

Shot blasting and testing

After heat treatment, the milled springs are subjected to shot peening to control the positive internal stresses in the material. This process improves the performance of the springs during compression and reduces shear stresses. In addition, shot blasting prepares the material for surface treatment by zinc phosphating and painting.

Surface treatment and corrosion protection

Zinc phosphating and painting

All milled springs undergo surface treatment to ensure effective corrosion protection. This is done through zinc phosphating and painting. Zinc phosphating forms a protective layer on the surface of the springs and increases resistance to corrosion. The varnish provides additional protection and gives the feathers an aesthetically pleasing appearance.

Epoxy powder coating

Before delivery, the milled springs are given an epoxy powder coating. This coating improves resistance to external influences and ensures long-lasting color. Production and batch numbers are applied to each nib using inkjet printing to ensure traceability and quality assurance.
