The construction of our four-frame presses is similar to that of a double sided press but they have an enlarged lateral passage.
They are distinguished by their robust and reliable workmanship. Thanks to rigid constructions and robust guidance assemblies, processes where great precision requirements are to be met can also be carried out on these machines.
A flexible and versatile machine concept makes it possible to use the presses in many different fields of applications. Each machine can be individually adapted to its designated task. Depending on the application, single-acting, double-acting or multiple-acting presses can be used. Different versions and equipment are provided accordingly.
The presses are often used for automatic productions or as transfer press.
