Check the integrity of welded corners with a quick, digital, and reliable test.
Test Pro Digital is the machine designed by GRAF Synergy to measure with extreme precision the breaking load on welded corners of PVC profiles, thereby ensuring a rigorous and replicable quality control in the production of window frames.
Thanks to a compact carbon steel structure and a hydraulic system with a certified load cell, it allows for standardized testing to be carried out directly in the workshop, eliminating the need for external laboratories.
The built-in graphic display allows for immediate data visualization and the export of results via USB.
5 reasons to choose Test Pro Digital
- Certified Precision and Digital Results. System with approved load cell for accurate measurements in Kg or Newton, with test graph displayed on screen.
- Total ease of use. Profile setup, test initiation, and result reading: all managed by a single operator.
- Immediate Break Load Analysis. A hydraulic piston applies a constant force on the welded joint until failure, highlighting the maximum peak.
- Wide range of testable profiles. Supports lengths from 350 to 740 mm, heights up to 600 mm, and thicknesses from 40 to 130 mm.
- Exportable digital reports. Test data can be saved to a USB drive, useful for internal checks or sharing with clients.
Product Details
Test Pro Digital allows for destructive testing to measure the mechanical strength of welded PVC corners. The test is conducted by applying a progressive force until the joint breaks, recording the maximum value achieved.
