The DY-20KN is a computerised double-column universal testing machine with a 0–20 kN load capacity. A Panasonic servo motor, servo drive and precision ball screw provide a stepless 0.001–500 mm/min crosshead speed over an 800 mm stroke, with 1/250000 force resolution and ±0.5 % accuracy on both load and displacement.
Interchangeable fixtures and a dedicated PC software package cover tension, compression, bending, shear and peel tests on metals, vulcanised rubber, plastics, films, textiles and composites, to GB, ISO, BS, ASTM, DIN and JIS methods.
Applications
A rigid twin-column frame keeps the load axis aligned when stiff specimens are pulled, which a single-column stand cannot guarantee. The system records force, displacement and derived stress–strain curves, and automatically evaluates tensile strength, yield point, elongation, modulus and peak force. An overload stop triggers when the measured force exceeds the set value by 10 %, and upper / lower travel limits protect the fixtures.
Select capacity at 1.5–2 times the maximum expected force: too large a range amplifies relative error at low loads, while too small a range leaves no margin. For thin films, adhesive tapes and low-force peel work, the single-column peel and tensile tester is the better match; for spring stiffness and small components, see the spring tension and compression tester.
