Current market status of hydraulic controller in Korea
PLC
The most popular
Slot or Card typed controller embedded
Useful to be extended to automation systems
Siemens, Allen Bradley, Mitsubishi, LSIS … etc.
Hydraulic Controller
Special functions needed for hydraulic unique features
Mainly developed by hydraulic component makers
Proportional or servo control demands exploded
Bosch Rexroth, Moog, Parker, Delta, Beckhoff, MTS, Delem … etc.
Used in European and American machine makers
Applications of Power Instruments
Presses
Powder presses
Die spotting presses, Try out presses
Deep drawing presses
Fine blanking presses
Die cushions of mechanical presses
Roll bending presses
Hydroforming presses
Test machines
Wave maker
Road simulator
Welding machines
Friction welding machine
Mobile applications
