The Computer-Controlled Heat Deflection Temperature (HDT) and Vicat Softening Temperature (VST) Test Machine is specifically engineered for determining the Heat Deflection Temperature (HDT) and Vicat Softening Temperature (VST) of plastics, rubber, and other polymer materials.

As an indispensable testing instrument, it is widely utilized in R&D institutions, universities, and enterprise Quality Assurance (QA) departments—supporting material research, product development, and quality control processes.

Additionally, the machine is equipped with sample holders featuring precise vertical adjustment functionality, enabling flexible positioning to meet standardized testing requirements.

The Computer-Controlled Heat Deflection Temperature (HDT) and Vicat Softening Temperature (VST) Test Machine is engineered to align with the accelerated development of the plastics industry and elevate the standards of material research and testing.

It is fully compliant with the latest international and domestic standards, including:

• ISO 75-1:1993 Plastics — Determination of temperature of deflection under load
• ISO 306:1994 Plastics — Thermoplastic materials — Determination of Vicat softening temperature (VST)
• GB/T 1633—2000 Thermoplastic materials — Determination of Vicat softening temperature (VST)
• GB/T 1634—2001 Plastics — Determination of temperature of deflection under load

Featuring advanced computerized control, the machine delivers stable performance, user-friendly operation, and a high degree of automation. These attributes position it as a state-of-the-art testing instrument for measuring the heat deflection temperature (HDT) and Vicat softening temperature (VST) of non-metallic materials, meeting the rigorous requirements of modern material testing.
