This means adding micro-textures as well as color effects to HVAC technical parts, in order to guarantee they match consumer expectations. Technical developments on laser graining have allowed reproducing surface looks that mimic wood, leather, and other materials.<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Transforming an object\u2019s <\/span><b>tribology<\/b><span style=\"font-weight: 400;\">, so that friction is removed or a soft-touch surface is produced.

Ascertain textures allow for a reduction in friction, energy is saved.<\/span><\/p><p><span style=\"font-weight: 400;\">At the same time, replacing painting or exterior coatings with a laser texture helps obtain <\/span><b>mono-material HVAC parts.<\/b><span style=\"font-weight: 400;\"> In the case of materials such as EPP and EPS, this means the parts are 100% recyclable.<\/span><\/p><h3><span style=\"font-weight: 400;\">Added aesthetic value<\/span><\/h3><p><span style=\"font-weight: 400;\">Modern laser graining processes, such as the<\/span> <span style=\"font-weight: 400;\">laser textures we\u2019ve developed at Knauf Appliances<\/span><span style=\"font-weight: 400;\">, allow companies to generate accurate, grained patterns that generate an improved aesthetic appearance.
