Efficiency which pays off
ALD Vacuum Technologies can look back on more
than 40 years of experience in the production of
vacuum heat treatment plants. Now, for the first
time, heat treatment can be integrated directly into
the mechanical production line because of the latest
development, vacuum heat treatment module, type
SyncroTherm®.

SyncroTherm®
World first
Increasing demands on transmission manufacturing
and costs require new solutions for a more efficient
production. The heat treatment module SyncroTherm®
provides the means to optimize the process chain.
The continuous piece flow leads to a more effective
and ecological production – and improves quality.
