Underpinners - Frame Assembly Machines

Semi-Automatic | Pneumatic | Production Underpinner

The U-300P is a bench top, base model for production joining applications where the customer is looking for speed and repeatability of joining the same sized moulding.

The design of the U-300P allows the operator to set up to 3 position stops for V-Nail insertions. The nail head pneumatically moves underneath the fixed frame and the joining cycle is actuated first by the hand lever locating the pre-set V-Nail position and then the V-Nail is inserted by actuating the foot pedal.

For those customers looking a similar type of joining machinery but require flexibility of joining different moulding sizes, refer to our U-300 unit.
