Variety of Applications

Few of our Installations

Success Story - PRICOL

Customer required high precision / tolerance press with closed loop force control for automotive component press. We were able to prove rapid movement and slow speed movement during press. The speed and position values could be dynamically changed by sending values from PLC to Press controller objects. Hence the same press is used for different sizes and variety of components just by changing the array objects. Closed loop force control feedback is also achieved using an external load cell fixed on to the press bed.

Success Factors	Customer Value
High repeatability ensures and meets the quality requirements of the pressed component	50% energy efficient compared to hydraulic presses.
Closed loop configurable position and force control.
	Same unit can be configured for different press components.
	Local repair/ service support.
	Local programming / commissioning support.
	Control from any third party Master PLC gives more flexibility and independence.

Success Story - Lucas TVS Pondicherry - Bearing Press

Success Factors	Customer Value
Precise position control which is essential for output product Quality control. This was not possible with existing hydro/pneumatic and hydraulic presses.	50% energy efficient compared to hydraulic presses.
Force vs Displacement plot functionality enables customer to identify root cause in rejected components.	Same unit can be configured for different press components
User set tolerance band for force vs displacement curve.	Local repair/ service support
Multiple types of components can be pressed using the same system. One click component select from software.	Safety features built-IN.
Automatic teach mode when adding a new component	Logged values of Force vs Displacement can be saved for future reference with Part name, date and time stamp.
saves enormous time comparing to adding the component Force, displacement data manually.

SERVO PRESS vs HYDRAULIC /PNEUMATIC / HYDRO PNEUMATIC PRESSES

SERVO PRESS	HYDRAULIC / PNEUMATIC/ HYDRO PNEUMATIC PRESS
Closed loop control.	Open loop control
Interfacing with front end is easy, comes with software package.	Front end is not applicable. No software.
High cycle speed	Low cycle speed
Full press capacity at full stroke Length	Full press capacity is not possible at full stroke Length
Force control is precise and software configurable	Force control not possible.
Position control is precise and software configurable.	Position control not possible.
Different press motion/force profiles can be achieved.	Profile Changing is not possible, fixed profile.
Additional features can be added with the help of program.Example: field bus communications, control sequence changes.	Additional features not possible.
80 % Energy efficiency.	Only 25 to 30 % Energy efficiency due to increased sizing of motor and continuous running of power pack. In pneumatics, electrical to compressed air energy conversion efficiency is lesser than 25%. Hence 2 to 3 times more energy consumption compared to servo electric press.
Tool protection is possible	Tool protection is complicated
Good response time, 10 ms	Poor response time, 500 ms.
Low maintenance. Only lubrication maintenance required approximately after service life.	Maintenance is high. Multi parts ( Filters, Valves, Fittings, Hoses) will be used in circuit and all parts should be maintained periodically.
