Advanced Testing Equipment

Anti static feature testing machine

Anti static feature testing machine

This machine is used to determine footwear anti static resistance, which is measured according to EN ISO 20344:2004, 5.10, S1,S1P,S2,S3,S4,S5 all require this test.

  • lies above 100 kΩ
  • less than or equal to 1000 MΩ

Shoe flexing testing machine

This tester is used for determining the flexibility resistance and or indicating the cracks of shoe or shoe sole through reciprocating flexing movements under the specified angle and frequency.

  • Bending angle:0-50° adjustable
  • Test speed:0~150cpm adjustable

Safety footwear impact testing machine

This equipment is mainly used for determination of impact resistance test safety shoes toes with a certain kinetic energy& a certain height. Test its subsidence degree.

  • EURO39,40/UK5.5-6.5: Min.13.5mm
  • EURO41,42/UK7,8: Min.14mm

Shoe dielectric resistance testing machine

This tester is used to determine the
isolation character of the shoe material.

By slowly increasing the voltage on the sole to the specified value, it checks if it can withstand that value in the prescribed time period.

Abrasion resistance testing machine

Here is abrasion resistance testing machine for outsole.It helps us to know the abrasion degree of the outsole material. the temperature should be between 21 to 25 degree.

  • Sole density> 0.9 g/cm³:loss in volume 150.0mm³
  • Sole density≤ 0.9 g/cm³:loss in volume 250.0mm³

Penetration resistance testing machine

The purpose of the test is to determine the penetration resistance shall be not less than 1100 N. Footwear component placed in the sole provides protection against penetration.

  • Metallic plate: Min.1100N.
  • Non metallic plate:Zero penetration.

Tensile strength testing machine

Tensile strength testing machine

The purpose of this test is to determine the tensile strength & elongation characteristics of fabrics, synthetic leathers, genuine leathers, webbings, laces, and threads, plastic, rubbers, elastomers, midsole and outsole foams.

  • Requirement: Min.15N/mm².

Tear strength testing machine

The purpose of this test is to to determine the tearing strength of the materials according to the tear method. This test is good indicator of a material’s resistance of tearing.

  • Tear strength for leather upper: Min.120.0N.
  • Tear strength for coated fabric/textile upper: Min.60.0N.

Compression testing machine

Compression testing machine

Safety footwear, incorporating protective features to protect the wearer from injuries which could arise through accidents.

It's designed to give protection against impact when tested at an energy level of at least 200 J and against compression when tested at a compression load of at least 15 kN.

Upper & outsole bond strength testing machine

The purpose of the test is to determine the internal tear strength between outsole and upper.

Bond strength shall be not less than 4,0 N/mm, unless there is tearing of the sole, in which case the bond strength shall be not less than 3,0 N/mm.
