One Control cabinet to control all testing systems;

Compartment design can be available to make all equipment in same height with the advantage to reduce to time, cost and mobile to move & upgrade test equipment.

3 - Main Technical Parameters

Crush, Nail Penetrate

Test Method

Crush

The test battery is placed between two planers and approximate 13KN crush force can be performed through hydraulic arm with an 32 mm diameter piston or bench clamp;

The crush remains till hydraulic pressure reading data up to 17Mpa.

Once crush force reached and system will release automatically;
