During operation, Universal Testing Machines (UTM) are critical equipment for material testing in QA/QC and R&D laboratories. Any malfunction can directly affect test accuracy, product quality, and project timelines.

In March 2026, VintechME Vietnam successfully provided repair services for a UTM at a major manufacturing factory in Vinh Phuc, Vietnam. Below are the detailed findings, root causes, and corrective actions.

Current Condition of the Universal Testing Machine

After on-site inspection, VintechME engineers identified several critical issues:

1. Loadcell Failure (Force Sensor Damage)

The loadcell was damaged, resulting in inaccurate force measurement
Significant deviation in test results
Unable to meet QA/QC testing requirements

2. Software & Communication Error

The control software failed to communicate with the testing machine
No data acquisition, display, or analysis possible
Continuous system error messages during operation

3. Mechanical Damage in Guiding & Transmission System

Guide columns and transmission components were bent, misaligned, and stuck
Caused by improper previous disassembly and maintenance
Direct impact on:
- Force accuracy
- Stroke precision
- Alignment during testing
- Equipment lifespan
