Innovative Computer Controlled Heat Deflection Temperature Plastic HDT and VST Test Machine for Advanced Material Research

The Computer Controlled Heat Deflection Temperature Plastic HDT and VST Test Machine is engineered to determine the heat deflection temperature (HDT) and Vicat softening temperature (VST) of materials such as plastics and rubber. These two parameters are critical for evaluating the thermal stability and high-temperature performance of polymeric materials.

This machine serves as an essential testing instrument for research and development (R&D) institutions, universities, and quality assurance (QA) departments of enterprises—supporting material formulation optimization, product performance validation, and quality control in the polymer industry.

Additionally, the machine's sample holders are equipped with an up-and-down adjustment function, enabling flexible and precise positioning of test samples to meet diverse testing requirements.

The Computer Controlled Heat Deflection Temperature Plastic HDT and VST Test Machine is engineered to align with the rapid advancement of the plastic industry and elevate the standards of material research and testing.

These machines are designed in strict compliance with the latest international and national 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)

Computer-controlled, these machines boast stable performance, user-friendly operation, and a high degree of automation. As such, they stand as the most advanced testing instruments for measuring the heat deflection temperature and Vicat softening temperature of non-metallic materials.
