Obiettivo del progetto (Objective)
'The occurence of density gradients in ceramic tiles during pressing is believed to be the main cause of defects during processing. Problems such as differential shrinkage and warpage typically arise leading to losses or down-grading of final products. Density gradients are caused by poor die design, bad practice and/or unsuitable particulate materials, with the resultant poor flow ability impacting on die filling uniformity. Currently, these faults go undetected until been fired, rendering them scrap, which is difficult to recycle and often sent to landfill. This project aims to develop an in-situ sensor that enables measurement of the density of ceramic tiles during pressing. The project is seen as making a short to medium impact by allowing early detection of faults thus reducing the extent to which value-added process steps are unknowingly applied to scrap ware. Detection of faults during pressing allows efficient recycling of waste material and use for pressing again.'
Introduzione (Teaser)
In the manufacture of tiles, a defect known as a density gradient, which develops during pressing, can cause tiles to be destroyed during firing. A recent project has developed a prototype sensor to detect density gradients during tile processing.
Descrizione progetto (Article)
The defect can occur as a result of poor mould design, inferior materials or bad technique, and is a major cause of losses during tile-making. Detection of density gradient faults before firing would lower manufacturing losses and allow for the recycling of good-quality materials.
Funded by the EU, the http://www.ceramgroup.com/projects/novapress/index.html (NOVAPRESS) project aimed to develop a non-destructive density gradient sensor that could be incorporated into the tile press. A UK based Research and Technology Organisation led the NOVAPRESS consortium, which included both academic researchers and small businesses.
Scientists first defined the common requirements and specifications of the sensor. At the same time, hardware was sourced or developed as necessary, and a first working prototype was produced. The team decided to first build a working laboratory sensor and then to apply it in a real-world environment.
Other work focused on hardware and software for control, and for feedback from the sensors to the mechanical controls of the tile press. Testing and demonstration of the off-the-press prototype was extremely successful.
Development of the final sensor is underway and it will be incorporated into several factories for commercial use. The NOVAPRESS technology is expected to add value to the ceramics market, and may be expanded to other manufacturing processes in the future.
