Foam repeated compression testing machine will accurately measure the thickness of the test piece, placed in the compression plate of the testing machine, at the rate of 60 times per minute, compress the specimen at the frequency of 60 times to compress the height of the specimen 50%, reciprocating compression up to 80.000 times, after 30 minutes at room temperature, measure its thickness to convert the compression deformation rate.

Applications

1. Applicable Foam Material Types

Polyethylene foam materials (corresponding standards: ISO 7214. JIS K6767)

Latex foam rubber cushioning materials (corresponding standard: JIS K6382)

Other flexible porous polymer foams (such as polyurethane soft foam, etc., adaptable to similar compression fatigue testing requirements)

2. Applicable Product Fields

Furniture industry: Foam cushions for sofas/chairs, backrest foam, mattress filling foam (testing for collapse and deformation after long-term use)

Automotive interior industry: Car seat cushioning foam, headrest foam, interior shock-absorbing foam (evaluating performance stability after repeated compression during driving)

Packaging industry: Foam materials for cushioning packaging (verifying protective capabilities after multiple compressions)

Daily necessities industry: Foam cushions, footrests, and other products (testing durability during daily use)

Standards

GB/T 40872-2021: Test Methods for Polyethylene Foams

ISO 7214:2007: Cellular plastics — Polyethylene — Test methods

JIS K6382: Test Method for Repeated Compression of Rubber Materials

GB/T 42258-2022: Determination of Fatigue Properties of Flexible Porous Polymer Materials by Constant Deformation Method

JIS K6767-1999: Test Methods for Polyethylene Foams and Cellular Rubber Materials

Features

1. Standardized Testing Functions and Procedures

The system simulates the repeated compression conditions of foam materials in actual use. The sample is compressed to 50% of its initial height at a frequency of 60 cycles/minute, allowing for up to 80.000 cycles of reciprocating compression.

After testing, the sample is left to rest at room temperature for 30 minutes before precisely measuring its thickness and calculating the compression deformation rate. The process conforms to professional testing standards and effectively evaluates the fatigue resistance of the foam. The system possesses precise sample thickness measurement capabilities, providing fundamental support for the accuracy of the test data.

2. Multi-Standard Compatibility

Compliant with international standard ISO 7214 (Test Methods for Polyethylene Foam Materials), Japanese Industrial Standard JIS K6767 (Polyethylene Foam Testing), and JIS K6382 (Latex Foam Rubber Cushioning Material Testing), it meets the compliance testing needs of different types of foam materials.

3. Flexible Technical Adaptability

The compression stroke covers 0-50mm, adaptable to foam samples of various thicknesses (such as common 20-50mm thick samples). Equipped with a stable operating system (such as a motor and LCD counter), it supports high-cycle (up to 80.000 cycles) continuous reciprocating compression. The testing process does not require long-term personnel supervision, and the system automatically stops after reaching the set number of cycles.
