FAQ:
Q: What is an HDT Machine?
A: An HDT Machine (Heat Deflection Temperature Tester) is a
high-precision testing instrument designed to measure the heat
deflection temperature of materials (especially thermoplastics)
under specified loads. It is often integrated with Vicat testing
functions (forming HDT VICAT Testing Machine) to simultaneously
determine the Vicat softening point temperature, evaluating
material thermal performance.
Q: What is the main function of an HDT Machine?
A: The core function of an HDT Machine is to test the heat
deflection temperature (HDT) of materials under load—i.e., the
temperature at which a material deforms to a specified extent under
a constant load. For integrated HDT VICAT models, it also measures
the Vicat softening point temperature, providing data support for
material thermal stability evaluation.
Q: Which standards are HDT Machines compliant with?
A: HDT Machines are strictly compliant with international and
national standards, such as ISO 75-1 (Plastics — Determination of
temperature of deflection under load), ASTM D648 (Standard Test
Method for Deflection Temperature of Plastics Under Flexural Load
in the Edgewise Position), and GB/T 1634 (Plastics — Determination
of temperature of deflection under load), ensuring test results are
authoritative and traceable.
Q: Which materials and industries are HDT Machines suitable for?
A: HDT Machines are mainly used for testing thermoplastic materials
(e.g., plastics, rubber, nylon, polyester, epoxy resin) and
non-metallic materials like electrical insulating materials. They
are widely applied in the plastics industry, chemical industry,
material R&D institutions, and quality control departments for
product development, performance verification, and batch quality
inspection.
Q: What are the advantages of HDT Machines?
A: HDT Machines feature high test precision, stable performance,
and a high degree of automation (e.g., computer control, real-time
curve plotting, automatic data processing). Integrated HDT VICAT
models have dual testing functions, saving equipment costs. They
also support multi-station testing, improving work efficiency, and
are easy to operate, suitable for both laboratory and production
site use.
