Shoe Peeling Strength Tester for Professional Footwear Adhesion Testing
During footwear production, insufficient bonding between the sole and upper can cause serious quality problems such as sole separation, customer complaints, product returns, and brand reputation damage.
The Shoe Peeling Strength Tester GT-KC41B is designed to determine the bonding strength between the shoe sole and upper at the toe and heel area of completed footwear.
It evaluates the force required to separate the sole and upper, helping footwear manufacturers verify adhesive performance, optimize bonding processes, and ensure consistent product quality.
The tester is mainly applicable to:
- Cemented footwear
- Molded footwear
- Injection molded footwear
- Safety shoes
- Sports shoes
- Leather shoes
The testing method evaluates the adhesion strength near the lasted margin where sole-upper bonding performance is most critical.
Why Footwear Manufacturers Need a Shoe Peeling Strength Tester?
Prevent Sole Separation Problems Before Products Reach Customers
Sole detachment is one of the most common footwear failures caused by:
- Incorrect adhesive formulation
- Insufficient bonding pressure
- Improper drying or curing process
- Poor surface preparation
- Inconsistent production parameters
Without laboratory verification, footwear factories may face:
Higher Product Return Rate
Customers expect shoes to maintain structural integrity throughout their service life.
Increased Production Costs
Failed shoes require rework, replacement, or disposal.
Brand Reputation Risks
Quality problems can negatively affect customer trust.
A Professional Shoe Sole Adhesion Testing Machine Helps You:
✔ Verify sole-upper bonding strength
✔ Compare adhesive performance
✔ Improve footwear production processes
✔ Control batch-to-batch consistency
✔ Meet footwear quality requirements

Testing Principle
How Does a Shoe Peeling Strength Tester Work?
The Shoe Peeling Strength Tester uses a specially designed peeling fixture connected with a force measuring system.
During testing:
- The finished shoe sample is fixed securely.
- The peeling cutter contacts the sole-upper bonding area.
- The tester applies controlled peeling force.
- The maximum peeling force is measured.
- The bonding strength performance is evaluated.
The test determines the resistance against separation between upper and outsole, helping assess the durability of footwear bonding structures.

FAQ
1. What is a Shoe Peeling Strength Tester?
A Shoe Peeling Strength Tester is laboratory equipment used to measure the bonding strength between the shoe upper and sole by applying controlled peeling force.
2. Why is sole upper adhesion testing important?
Poor bonding strength may cause sole separation during use. Testing helps footwear manufacturers identify bonding problems before mass production.
3. What footwear can be tested by Footwear Peeling Strength Tester GT-KC41B?
It can test safety shoes, sports shoes, leather shoes, casual footwear, and other bonded footwear products.
4. What is the difference between peeling strength and tensile strength testing?
Peeling strength evaluates the resistance of bonded layers separating along an interface, while tensile testing measures material resistance under pulling force.
