Quality Control

At Dolux, quality control is the foundation on which we base our reputation as a manufacturer of furniture of the highest quality. Our rigorous quality control system takes place at every stage of production, which guarantees that the final product meets the highest technical and aesthetic standards. A key component of this process is on-the-job quality control, which allows each component to be monitored and verified on an ongoing basis before it is passed on to the next stages.

Advanced measuring tools are used at each production station and are regularly calibrated. The calibration process follows strict procedures, ensuring accuracy and consistency of measurements. Thanks to this, we can be sure that each element meets precisely defined dimensional standards.

Bench quality control is not limited to measurements. Our team also performs visual assessments and checks the structural integrity of individual elements. Each product is carefully tested for compliance with design, dimensions and specific requirements, which allows to eliminate potential defects at an early stage of production. When we detect any imperfections, we immediately take corrective actions so that no defective element ends up in the final product.

Planing lumber to the desired size
