Products

Backed by extensive expertise in materials testing and industry applications, LSI offers a comprehensive range of accessories for specimen gripping, deformation measurement, and environmental simulation. These accessories can be integrated with LE and LD static testing systems as well as LF and EF dynamic fatigue testing systems. With modular selection, standardized interfaces, and application-specific engineering support, users can configure the appropriate accessory package according to material type, specimen geometry, loading mode, temperature conditions, and applicable test standards.

From conventional tensile, compression, and flexural tests to fatigue, durability, fracture mechanics, and mechanical testing under elevated- or low-temperature conditions, LSI accessory solutions are designed to streamline specimen installation and measurement, improve system compatibility and test stability, and enhance laboratory productivity. For special specimens, complex components, or non-standard test methods, LSI can provide application-specific grips, fixtures, and system integration support.
