Glossmeters for toughest
QC requirements
Automotive interior design is becoming more and more important in purchasing decision. A variety of materials, from leather to plastics, are used and need to be harmonized. Additionally, surface structures vary from large grains to fine stipples, usually with very low gloss. In order to guarantee a uniform look among the various parts very tight tolerances are specified.
As a starting point master standard plaques are usually manufactured with flat and several grained areas. These are sent to parts suppliers as their target to achieve with actual production parts.
As the master plaques and final parts are often made of different materials the suppliers work closely with the car maker. In the end final approval is given on a production part. This production part now becomes the standard for the supplier.
Instead of working with absolute gloss numbers, supplier production QC needs to be based on the signed-off part where only the differences are checked with the glossmeter. This procedure eliminates the reproducibility error as gloss is measured relatively on the same type of material and same surface.
micro-gloss S family
Only testing instruments with excellent precision will be able to objectively control production. The new micro-gloss S family offers improved performance for 60° gloss in the critical low gloss range (0-10 GU). This excellent accuracy can be guaranteed due to our patented calibration procedure in the production of the glossmeters.
