All our testing machines enjoy 12-month factory warranty; overseas customers get remote online debugging guidance, spare parts supply and technical operation training. Our products have been exported to over 70 countries globally

Which materials can be measured by your Vicat softening point tester?

It measures heat deflection temperature and Vicat softening temperature of plastics, hard rubber, nylon, insulating materials and fiber-reinforced thermosetting composites. Intelligent temperature control guarantees precise heating rate, ideal for plastic raw material incoming inspection and formula development in plastic factories.

Does your pipe pressure burst testing machine control test temperature automatically? What’s its main application?

Yes, the constant-temperature circulating system keeps stable test environment during long-time hydrostatic resistance and instant burst pressure measurement of thermoplastic pipes. It complies with GB6111 standard and serves raw material inspection, new product R&D for plastic pipe manufacturers, third-party testing labs and university laboratories.

What kinds of pipes fit your ring stiffness tester? Can it do long-term creep testing?

This equipment is designed for HDPE, PVC corrugated pipes, plastic drainage pipes and various plastic tubular products. Apart from ring stiffness, ring flexibility and flattening tests, it supports continuous long-term creep tests up to 1000 hours (42 days) as required by industry specifications, widely used for pipe factories and construction quality inspection institutes.

What test items can your WDW series computer-controlled electronic universal testing machine complete? Which international standards can it meet?

Our WDW universal tester is applicable for tension, compression, bending, shearing and peeling tests of metal, plastic, rubber and composite materials. It supports test procedures in accordance with GB, ISO, ASTM, DIN, JIS multiple domestic and global standards. Equipped with high-precision servo drive and dedicated test software, it automatically collects, calculates and exports test data including tensile strength, elongation at break and elastic modulus.
