WALLRAM übernimmt den italienischen Hersteller von Präzisions

WALLRAM übernimmt den italienischen Hersteller von Präzisions-Schleifmaschinen LIZZINI
Herborn (Deutschland) / Montichiari (Italien) - 11. April 2011
Die WALLRAM Gruppe, ein führendes Unternehmen in der Herstellung von HochpräzisionsWerkzeugen und Verschleißteilen aus Hartmetallen und technischer Keramik für die spanlose
Umformtechnik und Verschleißschutz, hat den italienischen Schleifmaschinenbauer LIZZINI
übernommen. LIZZINI entwickelt und produziert Präzisions-Schleifmaschinen für höchste Ansprüche
an Genauigkeit, und ist in der Fachbranche als besonders innovatives Unternehmen bekannt. Das
Traditionsunternehmen wurde in 1945 gegründet; in 2005 wurde eine hochmoderne Produktionsstätte in Montichiari bei Brescia/Norditalien in Betrieb genommen. Der Unternehmenskauf erfolgte
durch die italienische Tochtergesellschaft WALLRAM GrindTec S.r.l., die gleichzeitig ihren Firmensitz
von Brescia nach Montichiari verlegt hat.
“Die Integration von LIZZINI in unsere Unternehmungen ist ein strategisch wichtiger Schritt in der
Expansion unserer Firmengruppe“, sagte Hans-Peter Kämpfer, Gesellschafter und Geschäftsführer
der WALLRAM Gruppe und ihrer Muttergesellschaft Ziehstein-Kämpfer KG. “Hierdurch festigen und
untermauern wir unsere Strategie, eigenes Know How in der Fertigungstechnik konsequent und
langfristig mit unseren Kenntnissen in den Bereichen Material- und Werkstofftechnik zu kombinieren.
Erfahrungen und die guten Ideen unserer Mitarbeiter in Entwicklung, Konstruktion und Produktion
von Hochleistungswerkzeugen können nun auf direktem Weg in die Entwicklung des Maschinenbaus
einfließen. LIZZINI hat einen mehrjährigen Entwicklungsvorsprung gegenüber anderen Herstellern
von Schleifmaschinen am Markt, insbesondere bei der Bearbeitung von Präzisionswerkzeugen aus
Hartmetall und Keramik", sagte Herr Kämpfer weiter.
"Wer heute und auch in Zukunft seine Führungsrolle als Systemlieferant für Ultra-PräzisionsWerkzeuge behaupten will, der muss auch auf die Technologie in Produktion und Bearbeitung als ein
wichtiger Schlüssel für Präzision und Zuverlässigkeit Einfluss nehmen können. Mit WALLRAM
GrindTec als Hersteller von LIZZINI-Präzisionsschleifmaschinen haben wir nun diesen Schlüssel in
der Hand. Dies ermöglicht uns, neue Wege in der qualitativen und flexiblen Ausrichtung unserer
Produktion zu beschreiten, und unseren Kunden von LIZZINI Speziallösungen anbieten zu können.“
Der verantwortliche Leiter für das LIZZINI-Geschäft ist Massimiliano Tortelli, der an der Entwicklung
der Gesellschaft und Ihrer Produkte seit mehr als 20 Jahren wesentlich beteiligt ist. Auch er sieht
große Chancen für die Zukunft der LIZZINI als Teil der WALLRAM Gruppe: “Die Entwicklung und
Herstellung von Maschinen - kombiniert mit den Erfahrungen aus der Anwendung - ist ein wichtiges
Argument für unsere Produkte. Es ermöglicht uns, die Anforderungen der Kunden viel besser zu
verstehen und direkt bei der Entwicklung zu berücksichtigen. LIZZINI ist im Markt für seine
Hochpräzisions-Schleifmaschinen bekannt, und genauso für die Fähigkeit, kundenspezifische
Lösungen zu finden. Ich freue mich, dass wir diese Fähigkeiten als Teil der WALLRAM Gruppe auch
in Zukunft zeigen können und ich bin stolz, dass ich zusammen mit unserem Spezialisten-Team an
diesem Erfolg mitwirken kann.“
Die WALLRAM Gruppe ist Teil der Familien-Holding Ziehstein-Kämpfer KG mit weiteren
Produktionsstätten und Betrieben in Herborn und Essen (Deutschland), Krakau (Polen), Colorado
Springs (USA), Dale (Norwegen) und nun auch Montichiari (Italien).
Die WALLRAM Gruppe ist ein Anbieter von Präzisionswerkzeugen und Verschleißteilen aus
Hartmetallen, technischer Keramik und Werkzeugstahl. WALLRAM entwickelt und produziert
Präzisions-Werkzeuge und Konstruktionsbauteile für die Bereiche Metallverpackungen, Draht&Kabel,
Automotive, Offshore-Technik, Lebensmittelverarbeitung und die Luftfahrt.
