Künkel-Wagner was established in 1907 as a mechanical engineering
company specialized in foundry technology. Since then, the headquarters
of the internationally operating company including administration, a
research and development division, fabrication division and project
management is situated in Alfeld (near Hanover).
Since the construction of the very first hand moulding machines in
the year 1911, Künkel-Wagner has considerably contributed to the
advancement of the foundry technology and has developed a wide range of
foundry equipment.
In the late 1950s, Künkel-Wagner was one of the first companies
offering fully automatic moulding plants. Innovative moulding techniques
were developed and the first alternatives to jolt-squeeze moulding
machines presented. It did not take long for us to realise the
importance and relevance of the quality of sand preparation plants for
the casting process and we consequently integrated moulding sand
preparation in our own production programme.
There were concepts for core sand separation as early as in the
1980s. Even today, we continue to meet this early set target and offer
solutions for improved moulding sand quality in moulding plant
technology, as well as in the field of sand processing. With the current
compaction procedure, complicated contours can be produced reliably and
with the necessary strength. Simple casting machines were already built
in early years to round off the production programme; they have
developed into our current automatic pouring equipment.
Throughout the production of the machines of the latest generation,
process relevant parameters are recorded and alarm messages, if
necessary, generated and archived.Thus, the required documentation for
the process control can be guaranteed. In combination with innovation,
expertise and experience, all products boast durability and high-quality
implementation.
“Made in Germany” is backed by long experience and deep know-how and
forms major guiding principles for the development of our company.
