    It can be used for measuring the physical properties and adhesion of wire insulation before and after aging, and can test the tensile strength, elongation, tear, adhesive force, peeling force, shear force, adhesion force, connection force, etc. Using high-precision sensor, the sensor has the characteristics of high force measurement accuracy.
  • Needle flame testing machine
    The needle flame test is a simulation test project of using small flame ignition source program according to IEC60695-11-5 、GB/T5169.5、GB4706.1- 2005 and other standards.
  • Shore hardness tester
    The shore hardness tester is used to measure the thickness of rubber wire and insulating skin.
  • Test piece grinding machine
    This machine grinds rubber, EVA and other materials, and tests tensile force, tear, aging and tortuosity.
  • Constant temperature aging box
    Used for high temperature resistance test of wire insulation materials.
  • Insulation thickness tester
    The insulation thickness tester is designed for measuring the thickness of the insulator of the wire. It is in the form of a table. The meter is bolted on the base. It does not need a hand-held or needle type measuring clamp, and can accurately measure the deformed and tubular samples. According to UL1581 and other test standards.
  • Air exchange testing machine
    It is used for high temperature resistance and aging performance test of wire and bushing.
  • Standard light source color matching light box
