Hilywill Laboratory is part of the Qingdao Municipal Technology Center Laboratory. It possesses a range of state-of-the-art testing instruments and equipment essential for rubber and polyurethane materials, including chemical analysis, material preparation, performance testing, and
molding processing. The laboratory comprises four departments: the Physical Property Testing Room, the Material Performance Testing Room, the Mechanical Prop
erty Testing Room,and the Bench Test Laboratory. Included in the aforementioned are Mooney viscometers and ovens from the highspeed rail company, universal m
aterial testing machines by Taiwan Yuken and MetS, a small open mill, micro melting point testers, ball indentation hardness testers,microscopes, glue curing time te
sters, Brooke infrared spectrometers, Karl Fischer moisture testers, Netzsch red combination instruments, etc. These instruments operate at an advanced internation
al level. Additionally, several sets of sophisticated oil resistance test bench equipment specifically designed for advanced oil seal products have been installed, thus c reating optimal conditions for product quality control and the development of new products.
