Work on the project started in 2016 and in the following year Elematic provided the 96-metre pilot version of the 3.8-metrewide Multislab production line to Lujabetoni’s factory in Siilinjärvi, together with special equipment for cleaning and oiling the molds. The technology was then improved further based on actual use experience.

“Developing the production technology was a challenge because the molds have heating pipes and are quite complex in order to achieve flexibility for different uses. The most demanding task was developing the side molds for Superslabs, which were finalised after four of five protypes. Elematic was an efficient partner and we could find solutions together,” Isotalo says.

Success despite tight schedule

Once the technology was tested and proven to work at the Siilinjärvi plant, Lujabetoni ordered four complete production lines from Elematic for its new factory in Järvenpää, for which it had acquired facilities in February 2018. The company had been looking for a factory site near the growing construction markets of Helsinki and decided to buy an old paper machinery plant in Järvenpää for this purpose.

“The schedule was very tight. We started planning the factory immediately after the deal was done and began ordering equipment in the beginning of summer. The installations started in the autumn and the factory started production in less than a year,” Isotalo tells.
