Biuged BGD 310 Automatic Digital Cupping Tester

The Biuged BGD 310 Automatic Cupping Tester is an advanced, motor‑driven instrument designed to evaluate a coating’s resistance to cracking or detachment under controlled deformation. Built on the foundation of the BGD 309, the BGD 310 eliminates operator‑induced variability by automating the punch‑lifting process at a constant, standards‑required speed. A high‑definition display and integrated magnifier make failure detection clearer and more precise. The tester determines the exact deformation depth at which a coated metal panel begins to crack or lose adhesion. A 20 mm hemispherical punch presses the sample into a die, with deformation applied automatically at 0.2 mm/s, the speed required by ISO standards. The high‑definition screen and magnifier allow the operator to observe cracking in real time, ensuring accurate judgment of the failure point.

Key Features

Standards‑Compliant Automatic Operation

The punch rises automatically at a constant 0.2 mm/s, eliminating errors caused by manual lifting and ensuring highly comparable results. Conforms to:

• ISO 1520

• BS 3900 Part 4

• DIN 53166

• DIN 53233

Automatic Coordinate Positioning

The system memorizes the home position after zeroing and automatically locates the punch position, preventing operator‑induced positioning errors.

High‑Definition Visual Inspection

A built‑in high‑power magnifier and HD display allow clear, direct observation of cracking or damage throughout the test—no refocusing required.

Adjustable Punch Travel

The punch travel distance can be freely set from 0–18 mm, allowing precise control over deformation depth.

High‑Precision Displacement Sensor

A raster displacement sensor provides ±0.01 mm accuracy, ensuring reliable, repeatable deformation measurements.
