Jiangsu Hetian Technological Company has its own chemistry
laboratories and strict quality control department. From tungsten
powder to tungsten derivatives, every step is strictly monitored.
To ensure the quality, our company are fully equiped with
corresponding of facilities such as Atomic absorption
spectrometers, particle size & distribution analyzer, oxygen
meter, coercive force meter, carbon deternimator, grinding
machine, optical microscopes and so on.
For powders, following parameters will be inspected: F.S.S.S
particle size, particle distribution, specific surface area,
apparent density& tap density, carbon content, free carbon
content, oxygen content and trace elements contents etc.
All tungsten carbide rods will first experience crash tests
after sintering. Within standard distance, products will be
marked as a failure if not passed the crash tests. And then be sent
to inspect its saturation magnetization, coercive force,
phase diagram and so on.
