Quality Control

As a manufacturer of metal chair frames, we focus on the quality and durability of our products, which is why each stage of production is carefully controlled to ensure the highest quality of the frames. We are convinced that our chair frames will meet the expectations of even the most demanding customers. We work with clients from various industries and design racks that are ideally suited to their needs. Our company is not only the production of metal chair frames, but also professional customer service. We focus on transparency in relations with clients and provide full technical and logistic support.

The intrinsic quality of the various components, sub-assemblies and software is checked at each stage of design and manufacturing. During the pre-validation phases, performance, durability, and efficiency goals are meticulously assessed and cross-checked with the obligations defined in the specifications. These efficiency targets are cross-referenced and verified with our customer upon commissioning of the equipment, following the implementation of a duly developed validation protocol.

Particular Challenges of the Application: By tactile equipment, determination of the deepest point on a rough metal surface is neither simple or precise. As a consequence, often either too much material is removed, or the surface is still covered with defects which have to be eliminated by a following milling cycle. The equipment is arranged in parallel, so that the complete width of the slabs is covered. The sensors are calibrated to a common coordinate system and mounted on a movable gantry. Before measurement, the slabs are fixed in place. The scanners mounted on the gantry are guided over the measuring object, driven by an electric motor. The point cloud recorded by the four scanners is consolidated in a PC by means of the QuellTech image processing software which calculates the difference between highest and lowest point of the corresponding surface and compensates for possible inclination of the slab (detrending).
