Advanced HDT VICAT Testing Machine for Precise Plastic Vicat Softening Temperature Determination

The Vicat Softening Temperature (VST) is defined as the temperature at which a flat-ended needle with a 1 mm² circular cross-sectional area penetrates a thermoplastic specimen to a depth of 1 mm. This test is conducted under a specified perpendicular load (force) and at a selected uniform rate of temperature rise--consistent with international testing standards (e.g., ISO 306, ASTM D1525).

The Vicat Testing Machine adopts PC-based control, integrating high-precision measurement and intelligent operation features:

• Equipped with digital micrometers for high-accuracy deformation measurement, ensuring reliable test data acquisition.
• Supports real-time curve plotting, enabling visual monitoring of the penetration process and temperature-deformation relationship.
• Test data can be directly subjected to secondary processing on the PC; it is also exportable to Microsoft Office software (Word, Excel) for further editing, typesetting, and report generation.
• The sample frame is designed with automatic lifting functionality, which enhances operational efficiency, reduces manual intervention, and ensures consistent specimen positioning--optimizing test repeatability.
