Sole Abrasion Machine: Working Principle, Testing Methods & Buying Guide

Footwear soles are continuously exposed to friction, surface contact and repeated movement during walking and everyday use. The ability of a sole material to resist wear plays an important role in footwear durability and product quality. This is why footwear manufacturers and rubber testing laboratories perform abrasion resistance tests before approving materials for production.

A Sole Abrasion Machine is a laboratory testing instrument used to evaluate the resistance of footwear sole materials to abrasive wear under controlled test conditions. It helps manufacturers compare different rubber and polymer compounds, examine material wear and maintain consistent quality during production.

If you are searching for a Sole Abrasion Machine, Shoe Sole Abrasion Tester, DIN Abrasion Tester or Rubber Sole Abrasion Testing Machine, this guide explains the working principle, testing methods, applications, materials, buying considerations and important testing standards.

What Is a Sole Abrasion Machine?

A Sole Abrasion Machine is used to determine how a footwear sole material behaves when exposed to controlled friction against an abrasive surface.

During testing, a prepared specimen is brought into contact with an abrasive surface under defined conditions. The machine produces a controlled rubbing or abrasion action. The resulting material loss or change in specimen thickness is evaluated according to the selected test method.

The test helps footwear manufacturers assess the relative abrasion resistance of materials used in:

• Rubbber shoe soles
• Safety footwear soles
• Sports shoe soles
• Industrial footwear
• Leather footwear components
• TPR and other thermoplastic soles
• PU and EVAbased soling materials, where the selected method is applicable

The result provides useful information for material development, quality control and comparison of different sole compounds.

What Are the Other Names Used for a Sole Abrasion Machine?

Buyers do not always search using the same product name. Depending on their industry, application or required testing method, they may use different search terms.

Common names include:

Important: A DIN abrasion tester and a SATRA-type sole abrasion tester should not automatically be treated as identical machines. Always select the equipment according to the required test method and specimen arrangement.

Why Is Sole Abrasion Testing Important?

Abrasion resistance is an important property when selecting materials for footwear soles. A sole that wears excessively during use may affect product durability, appearance and customer satisfaction.

Sole abrasion testing helps manufacturers:

1. Evaluate material durability: Compare how different sole compounds resist abrasive wear.
2. Compare rubber formulations: Examine the relative performance of natural rubber, synthetic rubber and other compounds.
3. Support product development: Select suitable materials during footwear design and development.
4. Maintain production quality: Check whether different production batches provide consistent results.
5. Reduce material-related complaints: Identify materials with unsuitable abrasion performance before large-scale production.
6. Support quality documentation: Maintain test records for internal quality checks and customer requirements.

Laboratory abrasion results are useful for comparing materials under controlled conditions. They should not be treated as a direct prediction of the exact service life of a finished shoe because actual wear also depends on sole design, walking conditions, surface type and other footwear construction factors.

Working Principle of a Sole Abrasion Machine

The working principle depends on the machine configuration and the test method selected. Two configurations commonly considered for sole abrasion testing are the DIN rotary-drum type and the SATRA-type linear arrangement.

1. DIN Rotary-Drum Abrasion Method

In a DIN-type rotary-drum abrasion tester, a prepared cylindrical specimen is held in a specimen holder and brought into contact with an abrasive sheet attached to a rotating cylindrical drum.

The basic working sequence is:

1. Prepare the cylindrical test specimen according to the selected method.
2. Measure and record its initial mass.
3. Fix the specified abrasive sheet around the rotating drum.
4. Secure the specimen in the holder.
5. Apply the prescribed contact force.
6. Run the machine for the required test distance or number of rotations.
7. Remove the specimen and measure its final mass.
8. Calculate the material loss and, where required, volume loss using the specimen density and applicable test procedure.

The result helps determine the relative abrasion resistance of the tested material.

2. SATRA-Type Linear Abrasion Configuration

A SATRA-type linear configuration uses a different specimen arrangement and movement from the DIN rotary-drum method.

In this configuration, a prepared sole specimen is placed in its holder and moved across an abrasive surface under the specified test conditions.

The general sequence is:

1. Prepare the sole specimen in the required shape and dimensions.
2. Record its initial thickness or other required measurements.
3. Place the specimen in the sample holder.
4. Position the specified abrasive material.
5. Apply the prescribed load.
6. Operate the machine to produce the required linear rubbing movement.
7. Complete the test for the specified cycles or distance.
8. Examine and measure the specimen after testing.
9. Evaluate the wear or thickness change according to the applicable method.

The exact load, movement, test duration and evaluation procedure must follow the test method for which the machine is configured.

Remember: DIN rotary-drum testing and linear abrasion testing have different operating arrangements. Confirm the required method before purchasing the machine.

DIN vs SATRA-Type Sole Abrasion Machine

The two configurations should be selected according to the buyer's testing requirement, not simply because both are described as sole abrasion machines.

Materials Tested Using a Sole Abrasion Machine

Sole abrasion testing can be useful for evaluating different footwear materials. The actual suitability depends on the specimen preparation and the selected test method.

Not every material can be tested using identical specimen preparation or test settings. Always check the applicable method before conducting the test.

Sole Abrasion Testing Procedure

A reliable abrasion test requires correct specimen preparation, machine setup and evaluation.

A general testing workflow includes:

Step 1: Specimen preparation

Prepare the test specimen according to the dimensions, shape and conditioning requirements of the selected method.

Step 2: Initial measurement

Record the initial mass, thickness or other measurement required by the method.

Step 3: Machine preparation

Check the abrasive surface, specimen holder, loading arrangement and machine condition.

Step 4: Specimen mounting

Secure the prepared specimen correctly so that it remains in the intended position during testing.

Step 5: Test setting

Set the load, movement, test distance or cycle count according to the applicable test procedure.

Step 6: Run the test

Start the machine and allow the specified abrasion action to take place.

Step 7: Final measurement

Remove the specimen carefully and measure the required parameters after testing.

Step 8: Result evaluation

Calculate or record the material loss, volume loss or thickness change as required by the selected method.

Step 9: Test documentation

Record the material identification, method, test conditions and results for quality-control comparison.

Standards Related to Sole Abrasion Testing

Before buying a sole abrasion machine, identify the exact standard or customer test specification required by your laboratory.

Some important references associated with rubber and footwear abrasion testing include:

- ISO 4649: Determination of abrasion resistance of rubber using a rotating cylindrical drum device.
- ASTM D5963: Standard test method for rubber property—abrasion resistance (rotary drum abrader).
- DIN 53516: A historical DIN reference frequently found in older equipment specifications; check the current applicable ISO reference and the edition required by your customer.
- EN ISO 20344: Test methods for footwear, including applicable outsole-related testing requirements.
- SATRA TM174: A footwear soling-material abrasion test method associated with rotary-drum abrasion testing.

Do not assume that a machine complies with all these standards simply because the standards appear in a general product description. The machine configuration, accessories, test settings and procedure must match the relevant method.

Also note that SATRA TM362 is a separate biomechanical method for assessing abrasion resistance of soles using a walking-machine arrangement. It is not simply another name for a linear specimen abrasion tester.
