A device which tests the Finish cracks (Cracked finish, Neck ring crack, cracks under finish, etc.) of glass bottles
This device is used for lot testing and can reduce the output of defective products.
A device which accurately measures dimensions or moldings using the shadow of a glass bottle ex) Stopper molding, shoulder difference, measurement of external height, screw caliber, ring thickness, -etc
(When the internal diameter of container is not mold accurately, gasket easily misses or leaks during use or storage after filling.)
Occurs if the stress is not removed due to various factors (temperature change, etc.) during slow cooling to remove stress inside the glass after molding
Stress inside the glass is called strain.
For perfumes requiring use of pump for spraying of contents, pressure works vertically to fasten the pump after filling
A device that measures the strength of glass. The strength of bottle may weaken in some cases due to cracks, strains or the thickness of the glass inside the bottle
Checks how much internal pressure of a case can endure using water pressure
Measures the strength of a glass bottle. The strength of a bottle weakens in some cases due to cracks, strains, or glass thickness inside the bottle
Checks the damage of a glass bottle due to a change of temperature using cold and hot water tanks
Measures the strength of capping (opening and closing)
