Sole Flex Cracking Resistance Tester

DESCRIPTION / TECHNICAL SPECIFICATIONS

The durability of a shoe begins with its foundation: the sole. A cracked or broken sole is not just an aesthetic issue; it is a total functional failure that ends the product's service life. We present a fundamental testing device specifically designed to evaluate the resistance of sole materials to cracking caused by repeated flexing. This machine is a vital instrument for sole manufacturers, rubber compounders, and footwear brands committed to ensuring the most critical component of their products can withstand the stresses of daily use without failure.

The most significant advantage of this tester is its compliance with a suite of the most respected international design standards: EN344, SATRA TM161, and ISO 17707. This multi-standard compliance makes this machine a highly versatile and globally recognized testing solution. It means that with a single device, you can validate your products for the European market, meet stringent international client requirements, and implement ISO-based internal quality assurance protocols. The machine works by continuously bending material samples like soles, rubber, or PU at a 90-degree angle at high speed to simulate accelerated wear, allowing you to observe crack initiation and propagation in detail.

Engineered for efficiency and reliability, this machine has the capacity to test three soles simultaneously, increasing throughput in a busy laboratory environment. The testing process runs at a high speed of 125 to 150 cycles per minute, significantly accelerating the acquisition of material fatigue test results. Every cycle is accurately recorded by an LCD digital counter capable of logging up to 999,999 cycles, ideal for long-term endurance testing. All testing parameters, from the angle and shaft diameter to the speed, are precisely designed to meet the strict specifications outlined in these international standards.

With its robust construction and a weight of 98 Kg, the machine guarantees operational stability for consistent and repeatable results. Its enclosed design ensures safety during high-speed operation. Integrating this sole flexing tester into your material R&D and production quality control is a strategic move. It not only prevents product failures in the hands of the consumer but also provides quantitative proof that your materials meet some of the world's most demanding quality benchmarks, opening doors to new markets and cementing your brand's reputation for high quality.
