Microcomputer Controlled Servo Hydraulic Universal Testing Machine
Dual-column material testing machine for tension, compression, bending and shear test of various materials
Applications
This testing system is perfect for research institutions, universities, and industries such as metallurgy, aerospace, machinery manufacturing, and boiler production, where material strength and reliability are critical.
This dual column hydraulic testing machine utilizes a fully digital closed-loop control system that ensures precision at every stage of the testing process. Its graphical data processing module allows for post-test analysis, including the ability to zoom in on test curves for deeper insights. With built-in support for international standards like ASTM, DIN, ISO, JIS, and BS, it can handle a variety of materials and testing methods, whether it’s tensile, compression, bending, or shear testing. The control system offers smooth transitions between force, deformation, and displacement control modes, making the testing machine versatile for complex testing scenarios.

Features
- Featuring a bottom-positioned hydraulic cylinder, this design minimizes friction and increases test accuracy. The hard-contact setup between the working table and the hydraulic piston ensures precision, eliminating common issues like misalignment found in older spherical contact designs
- The primary and auxiliary hydraulic cylinders are equipped with gap-free seals, ensuring there are no leaks. The machine also features a direct push clamping mechanism that secures test samples, avoiding the slippage and deformation that can occur with traditional clamp designs, while also making fixture changes quick and easy
- Designed to meet global standards, these hydraulic universal testing machine can handle tests that comply with ASTM, DIN, ISO, JIS, and BS requirements, ensuring reliable, repeatable results for a wide range of material tests
