In caster wheel manufacturing, material quality and structural design directly affect durability, load-bearing capacity, and lifespan.
To guarantee long-term reliability, every wheel undergoes a comprehensive testing process — including abrasion resistance, tensile and tear strength, material aging, tread thickness, and antistatic resistance evaluations.

1. Wheel Material Abrasion Resistance Test

The abrasion resistance test is designed to evaluate how well the wheel withstands wear during regular use.
This test provides insights into the wear mechanism, abrasion rate, and overall durability of the wheel material, offering valuable data for material optimization and design improvement.

Using a Wheel Abrasion Testing Machine, the wheel is subjected to continuous friction under specific pressure and speed to simulate real-world conditions. The equipment measures surface wear, volume loss, and friction coefficient changes.

Purpose of the test:

• Evaluate the abrasion resistance of different materials (TPR, PU, nylon, etc.)

• Predict the service life of the wheel

• Optimize formulas for improved wear performance

2. Material Tensile and Tear Strength Test

The tensile and tear resistance tests assess the structural strength and toughness of the wheel material — ensuring it resists cracking, stretching, or deformation under stress.

• Tensile Test:
  The sample is stretched until it breaks, measuring the maximum tensile strength and elongation at break.
  → Higher tensile strength means stronger material; lower elongation indicates better resistance to deformation.

• Tear Resistance Test:
  The sample is torn in a controlled direction to measure tear strength.
  → Higher tear resistance means the material is less likely to crack or split during operation.

Conclusion:
The less the material stretches or tears, the stronger and more durable the caster wheel will be — even under heavy loads or impact conditions.

3. Material Aging Test

The material aging test evaluates the wheel’s performance stability under high temperature and atmospheric pressure.
Using a Thermal Aging Test Chamber, with temperatures adjustable up to 300°C, we simulate long-term heat exposure to measure performance degradation.

After testing, aged samples are compared with unaged ones to determine thermal stability and adaptability in high-temperature environments — ensuring that our wheels perform reliably in industrial and outdoor settings.

4. Tread Thickness Measurement

Tread thickness directly influences a wheel’s shock absorption, wear resistance, and load capacity.
Using precision calipers, we measure tread thickness during production to maintain a consistent range between 5mm and 8mm, ensuring optimal elasticity and durability balance.

5. Antistatic Resistance Test

For caster wheels used in conductive or ESD-sensitive environments, antistatic resistance is a key quality indicator.
We measure electrical resistance using a Resistance Tester, as shown on the right.

Our current antistatic wheels achieve a resistance value of only a few ohms, providing excellent conductivity.
For enhanced conductivity, specialized conductive materials can be added to further reduce resistance.

Through rigorous caster wheel testing — covering abrasion, strength, aging, thickness, and antistatic performance — we ensure that every product meets the highest standards of durability, stability, and reliability.
Each wheel that leaves our factory reflects our commitment to consistent quality and dependable performance in every application.
