This machine is used for testing the rubber ,foam static compression ,put it between the tablet,use the screw to fix.When the ovenware up to suitable temperature,Compress rubber and put it on
is used to determine the rebound-character of the specimen of rubber product, which endures a certain compression force under the specified time period. Put the specimen onto the test pan leverlly and grip it between two compression plates. Through the specified time period, take it out and cool it down then measure its center thickness to get its rebound rate.
This tester is the steel ball falling in soft foam plastic or other flexible material sample, measuring instruments, the height of the rebound in the test project is mainly used for the determination of polyester elastic material because of the elastic energy in the coefficient of restitution. By microcomputer and photoelectric technology, electromagnetic control, digital tube display directly back to the weak coefficient values.
The machine is mainly used to measure the resistance of materials to repeated twists and turns, especially for the construction of the sole .
During the test, the maximum bending stress line was treated in the anti-slip pattern on the sole, and the three small openings were penetrated by the slitting knife. After a certain number of turns at a specific speed of 90° bending angle, use a magnifying glass to check the resistance of the sole
The instrument through test drive a certain specification and tensile strength of the specimens with a certain load required to calculate the maximum static slide coefficient of samples, to determine the soles slide properties of the material, the equipment can test the finished shoes, the sole and only test specimens. Can do dry, wet, and the oil type
NBS rubber abrasion testing machine is used to determine the resistance to abrasion of rubber products and sole materials. Mount specimens on this machine and rub specimens by the rotating abrasive paper, and then their abrasion condition will be checked out
The safety footwear industry requires specialized testing equipment to ensure that safety footwear products meet the required safety standards and provide adequate protection for workers.
