Quality control points are used for the early detection of faults in production, logistics and business processes, and prevent defective products or processes from proceeding further. They are based on defined quality criteria, testing procedures and KPIs, supported by technical integration, monitoring and real-time optimisation.
Muster operates customised Q-Gates at its own site and offers flexible solutions that can be adapted at short notice. Furthermore, Muster supports the implementation and operation of external Q-Gates with its experience, standards and technical expertise.

Mechanical polishing is one of the most demanding surface-finishing processes. Even the slightest variations in pressure, speed or polishing compound can lead to poor results – particularly with complex geometries or delicate materials.

The fabrication of leather and metal trims requires the utmost precision in craftsmanship and a deep understanding of materials and manufacturing techniques. Tolerances are often minimal, and errors in cutting, bonding or assembly have a direct impact on the look and feel of the product.

Smart Surfaces combine electronics, design and materials in a single element – and the demands placed on quality assurance are correspondingly high. Only by comprehensively testing functionality, appearance and durability can a reliable, high-quality solution be guaranteed.
