The worldwide demand for valuable floor covering of parquet has been increasing for years. To meet the expectations that go along with the image of a high-quality, modern and durable flooring, it is necessary that the individual components as well as the finished products are subject to a reliable quality control. A case study with Scheucher:
Since 99 years, wood products have been manufactured in Mettersdorf am Saßbach in Styria. Today, the company in the fourth generation is known as manufacturer of high quality parquet. In 1996, it focused consistently on the production of parquet. The increased demand for high quality flooring generated new growth opportunities for Scheucher. The company currently produces approx. 2 million m² parquet per year. This quantity shall be increased by 50% in the next years. Scheucher exclusively produces in Mettersdorf.
A modern floor must meet numerous requirements. It must have a good thermal conductivity as an increasing number of underfloor heating systems are installed. For this end, it must be available with an optimised structure in different formats, colours and types of wood to offer creative freedom to the architects. Scheucher Parkett produces according to the two and three-layer process to meet these requirements. The two-layer parquet consists of a wearing surface and a supporting surface with the wearing surface made of a noble hard wood layer and the supporting surface of local soft wood or plywood. The 3-layer parquet also consists of a wearing surface and a supporting surface; a spruce-wood veneer is added on the rear side - everything also made of solid wood. Both production processes are subject to quality control.
The individual components as well as the final product are inspected.
The production of the parquet is monitored by measuring systems at different points to guarantee a high product quality. Scheucher avoids returns and complaints by a proactive quality control. An optimal moisture of the supporting surface must be guaranteed before pressing the individual layers so that a flawless final product is obtained. For this end, Scheucher relies on the micro-wave technology. The GreCon MM6000 VS guarantees a reliable moisture determination independently from density, thickness or colour. Before the system based on microwave technology has been commissioned, Scheucher worked with capacitive moisture analysis systems.
- quick and exact determination of the moisture
- full material penetration
- no influence of density or colour
- contact or non-contact measurement even in case of panel-shaped materials
Besides the determination of the moisture of the supporting material, parquet pressed from individual layers is checked for delamination and flaws. The GreCon UPU 6000 fs is used here. The system inspects the complete surface of the parquet board for flaws so that bad boards can be sorted out at an early stage. Complaints e.g. for a delamination of the top layer of the parquet are avoided proactively.
Thanks to the inspection of the parquet boards it is possible to draw conclusions as to the quality of the supplier so that no loss of quality by weaknesses of the intermediate product slips into the final product.The production quality is further increased by the installation of a new press. In the course of the installation, the GreCon UPU 6000 fs changes its location. In the future, inspection will take place directly behind the press so that it is possible to inspect the boards for quality losses as early as possible. The consequence: expensive and time-consuming production steps as grinding, cutting or filling of knotholes of faulty parquet boards are not necessary anymore as they can be identified and fed out at an early stage.
- Inspection of the the full surface
- Inspection without contact
- Early detection and localisation of hidden flaws
"Our objective is not a cost leadership - we are famous on the market for being a flexible and reliable partner of the crafts with short reaction times."
"The big advantage of the microwave is the reliable determination of the moisture independently from the bulk density, branches or the colour of the material."
"Any repair costs for faulty parquet boards are 100 times higher than the value of the individual board."
"We have been using the UPU for about one year and are very satisfied with the quality control. For the first time we detect flaws early."
