Universal Tensile Tester for Molded Plastic Dumbbell Specimens

Computerized tensile and flexural testing machine for injection molded dumbbell bars. Gives tensile strength, modulus and elongation of engineering plastics for molders and polymer QC laboratories in automotive and appliance supply chains.

Specification

A two-column load frame drives the crosshead at a set speed while a load cell records force. A clip-on extensometer measures strain on the gauge length of Type I dumbbells. The same machine runs three-point flexural tests using a bending fixture.

Features

• Load cell capacities 5 kN to 50 kN
• Speed range 0.5 to 500 mm/min
• Servo motor drive with ball screw
• Pneumatic or wedge grips for dumbbells
• PC software with stress-strain curves
