This machine is used to measure the indentation hardness of porous elastic materials. The polyurethane foam sample can be tested according to the national standard, and the compressive hardness of sponge, foam and other materials can be accurately measured. In addition, it can also be used to measure the specified compression hardness of the seat foam (such as backrest, seat cushion foam, etc.)， and accurately measure the compression hardness of each foam part of the seat.
Application
Measurement of tensile strength, tear strength, elongation at break, indentation hardness, and compressive stress of polyurethane foam plastics.
Standards
ISO 2439: Flexible cellular polymeric materials — Determination of hardness (indentation technique)
ISO 3386-1: Polymeric materials, cellular flexible — Determination of stress-strain characteristic in compression
ASTM D3574:Standard Test Methods for Flexible Cellular Materials-Slab, Bonded, and Molded Urethane Foams
Accessoriess
1. Transmission System:
Typically, the reduction gear unit of the main machine's transmission system uses a worm gear reducer, but it has inherent drawbacks such as large backlash and slow response speed. Our company's WSM series products utilize an AC servo motor from a Japanese (or other imported) company, which drives a ball screw through a circular arc synchronous belt pulley reduction system. This transmission system has no backlash and offers a fast response speed, thus ensuring the control accuracy of test force, deformation, and displacement.
2. Guiding System:
In addition to the ball screw guidance, the moving crossbeam of the testing machine is also guided by two columns (in conjunction with linear bearings). When the moving crossbeam is subjected to force, the special double-guide mechanism makes the moving crossbeam act as a fixed beam structure. Therefore:
a) The axial and lateral stiffness of the testing machine are greatly improved, with axial stiffness reaching 2 × 10⁸ N/m;
b) The oscillation of the moving crossbeam and the vibration generated during sample fracture are reduced.
