At Laser Technology Janssen bv, we specialize in laser ablation and machining of shims and components, including those made from spring steel.
These ultrathin, resilient metal components are used in applications where precision, stability, and flexibility are essential.

From precise spacers to technical spring elements, we deliver custom solutions on a micron scale.
What are shims?
Shims are thin, custom-made metal plates used to correct gaps, absorb tolerances, or precisely align components.
They are commonly used in precision mechanics, machine construction, aerospace, and medical equipment.

-
Thicknesses from 0.005 mm
-
Available in stainless steel, brass, copper, aluminum, and other alloys
-
Precise contours thanks to laser cutting/laser ablation (tolerances up to ±0.01 mm)
-
Possible with micro identification markings or coding
What is spring steel?
Spring steel is a special type of metal strip (often stainless steel or high-quality spring steel) with controlled spring properties.
It is used for components that need to be elastic, wear-resistant, and dimensionally stable.
Think of contact springs, clips, locking springs, or return elements.

-
Laser processing prevents stress build-up and deformation
-
Consistent quality for both series production and prototypes
-
Possible with micro perforations, slots, or complex geometries
Our expertise in shims and spring steel products
At Laser Technology Janssen BV, we combine precise laser cutting technology with in-depth knowledge of material properties and spring behavior.
This enables us to supply components that not only fit perfectly but also perform reliably over the long term.
