Project Description

Footwear flexing resistance tester

Finished Shoes Bending Tester China Manufacturer

Shoes Flexing Tester is designed to evaluate the resistance of final shoes to repetitive flexing and cracking.

The flexing testing can be performed in dry or wet conditions, and it helps footwear makers adjust and improve the quality of products.

This Footwear Tester is suitable for most footwear, including sneakers, casual shoes, occupational shoes, other finished shoes, etc.

Principle of Footwear Flexing Resistance Testing Machine

The finished shoe sample is mounted in the grips which can make the reciprocating motion, and continuously bent along the natural flexing line at a constant speed and specified angle. Flexing is completed once either preset flexing time or the number of flexes is reached. The operator observes for damage and evaluates the flexing resistant ability of the specimen.

Shoes Flexing Tester Features

  • Made of precision stainless steel to cause this flexing machine to be sturdy and durable.
  • Specimens are easy to be mounted and dismounted from the grips.
  • The humanized design ensures that the testing machine to be easy to operate.
  • The belt pulley is tightly coupled to the shaft, resulting in the minimum wear and noise level during the work.
  • Stations can accommodate four shoes(2 pairs of finished shoes) to be tested each time.
  • The testing speed can be adjusted according to the test angle.
  • The machine is steady and smooth while running, owing to the vibration offset design and quakeproof feet.
  • The counter with a digital display is available for better usability.
  • Fitted with acrylic-made clear lid to cover the specimens to protect operators during the test.

How to Use The Shoes Flexing Tester

  1. Position the flexing line (draw a line along the length of the insole starting from the mid-point of the toecap and ending at the mid-point of the heel, and measure the distance of this line from the heel end to the direction of the toecap end based on the value specified on SATRA TM92 to find and mark the flexing point, then retreat 5 ± 1mm to heel direction down the longitudinal line to locate a point, draw the second line across this point perpendicular to the first long line, this line is referred as Flexing line).
  2. Set the flexing angle and speed at 140 ± 10 cpm under the relevant specification.
  3. Mount one shoe or a pair in the clamps of flexing testers firmly, then start the machine.
  4. Suspend the tester and Inspect whether shoes are held tightly by the grips after 500 cycles.
  5. Stop the machine, check and evaluate the damage to the specimens after the required inspection stage reaches.
  6. Record all types of damage at each inspection stage. Testing is completed If the shoe has failed or has been subjected to prescribed flexing cycles.
