A long-standing Czech refractory maker, founded in 1892 and now a member of the German PD Group, one of Europe’s biggest manufacturers, PD Refractories has again chosen Sacmi presses to complete a major new investment.
Three new machines will be heading for Velke Opatovice in the Czech Republic, where they will join the four already installed in the same facility and the one in the Svitavy production plant.
The first, to be delivered in late March, is a PHR 550 long-stroke hydraulic press - soft powder fill 800 mm - of the very latest generation, fully automatic, designed by Sacmi to combine productivity and flexibility. The press is characterized by its quick mould changeover system (under an hour) and control software that, together with a soft filing capacity of up to 800 mm, ensures maximum finished product quality and uniform density throughout the piece to prevent the possible formation of any "weak points".
In addition to the PHR 550, a PHR 1008 will also be heading to the Czech Republic: this hydraulic press has a dual action pressing force of to 10,000 kN and features a floating die-holder table. Fully automated, the new press – a short-stroke type with a soft filling capacity of up to up to 600 mm – was designed by Sacmi for optimal management of complex-geometry refractories such as cones, stoppers, checkers and so on. The press, which will be delivered in early May, offers outstanding reliability thanks to a redesign by Sacmi using tension state analysis criteria based on FEM simulation, while considerable versatility is ensured by the rapid mould changeover system thanks to automatic alignment and clamping.
Finally, the last few days also saw the signing of another contract for the supply of an additional PHR 550, a short-stroke version this time, to be delivered at the end of July, again to the Velke Opatovice factory.
All the supplied presses have already been prearranged for the future production of nozzles and pipes. These machines are the result of Sacmi’s years of experience in developing optimal pressing algorithms that allow constant quality control of pressed pieces, in terms of both geometry and density. These, then, are the characteristics that led the Czech company to renew its trust in Sacmi - and which ensure the Group plays a leading role with major international players in the industry.
