- THE MAGAZINE
According to fair organizers Messe München International, an important factor in the resounding success of ceramitec 2000, which takes place on a three-year cycle, was the fact that it celebrated its premiere at the New Munich Trade Fair Centre in Munich-Riem.
A survey of both visitors and exhibitors showed that the mood in the industry has considerably improved compared to 1997. Approximately 71% of visitors and 72% of exhibitors said they regarded the current situation of the industry as “excellent to good,” compared to just 57% and 47%, respectively, who felt that way in 1997. Additionally, more than 80% of both visitors and exhibitors thought the situation would remain the same or would improve still further in the near future.
According to Eugen Egetenmeir, director of Business Unit Capital Goods of Messe München GmbH, worldwide sales generated by ceramic products are estimated at around $98 billion—an increase of around 40% compared with 1990. However, more than one-third of total sales is generated by technical ceramics, which continue to increase in importance. Other fields such as decorative ceramics, sanitaryware and tableware are struggling with continued global competition. Southeast Asia is becoming an imposing figure in the field of traditional ceramics, but has also become a major market for U.S. and European machine manufacturers and suppliers. ceramitec 2000 was a demonstration of just how international the market and competition have become.
For those who were unable to attend the event, Ceramic Industry compiled a review of some of the stands. Following is a glimpse of what visitors to ceramitec saw as they walked the show floor.
MachineryCERAM Technology Ltd., Stoke-on-Trent, U.K., launched a thermal transfer decal printing system—a computerized system that produces ceramic decals “to order.” During printing, a ribbon, which has thermoplastic ink coated onto a thin polyester film, and the substrate to be printed pass under the print head. The head consists of tiny heated pins, which melt the thermoplastic ink and allow transfer from the ribbon to the substrate. The decal is then soaked in water, applied in reverse and fired the same way as a conventional waterslide decal. The system is designed for short, specialized production runs where current decal systems are unsuitable.
