QUALITY DEPARTMENT

IT CAN’T BE ANY MORE ACCURATE – THE PERFECT IMAGE.

It is often the nearly invisible details that are nonetheless decisive for the surface’s overall impression. Precise monitoring and ongoing comparison with the engraved surfaces ensure that all the parameters – in terms of the structure, roughness, depth of the grain, and gloss – are retained throughout the entire manufacturing process.

SCANNING

A scanner specially developed with and for KRÜTH can reproduce the smallest details in grey scales.

Details of an engraving can already be recognized in the development stage, so that they can be worked out true to the original.

MEASURING

The visible impression of a surface is decided in the range of a few micrometers and supports the entire manufacturing process.

TESTINGS

Two ensure that the mold meets quality assurance expectations, different basic test options are used.

  1. Digital dial gauges are used at the mold whenever the depth of the structure is to be determined directly and quickly.
  2. In addition, an optical microscope is used to document the surface quality at up to 400-fold magnification.
  3. Engraving details can be reliably evaluated by a combination of interferometric measuring head and chromatic distance sensor. Designed for two- and three-dimensional measurements, the method is based on the principle of chromatic aberration. The hights in the measuring range are exactly determined from the spectral distribution. The non-contact method detects transparent, reflective and matt surfaces equally well. (FRT and Nanofocus)

Upon agreement with the customer, an “engraving passport” can be issued for each engraving pattern.

SERVICE

FAR MORE THAN JUST SUPERFICIAL.

Surfaces are our passion. As a partner to a wide variety of industries, we consult and mentor our customers along the entire process chain.

From the first design idea to the finished product KRÜTH is at your side with profound knowledge and experienced employees to offer well-founded know-how in the fields of design, technology and/or tooling construction. We are only satisfied when the product lies flawlessly in your hands. To ensure this in the long term KRÜTH offers services for optimizing or repairing engravings. These include surface treatments such as polishing as well as welding work using laser and TIG processes with specialized partners. If repairs are necessary on site, our technicians also work directly at the production site.
