Ceramic Capsule Cutting Blade
Density : 6.00 g/cm3
Mohs Hardness : 8-9
Colour : Black and White
Ceramic capsule cutting blade is a necessary component of the trimming process used in the manufacturing of empty hard gelatin capsules. As is well known, empty capsules are the most commonly used pharmaceutical excipient. Capsules have been widely used as a result of the improvement of people's living and medical standards, as well as nutrition and health products. By the year of 2021, China's yearly consumption of empty capsules is expected to reach over 200 billion tablets. The worldwide demand is significantly higher. Automated manufacturing enables effective control of output and quality of empty capsules. In the process of automated cutting, the hard capsule trimming knife plays a basic role. Normally speaking, the hard capsule cutting blades made of advanced zirconia ceramic have a lower fracture toughness than metal blades, however, since the capsule material is soft and the thickness is relatively small, ceramic blades can be an excellent option. Ceramic capsule knife has unique wear resistance and chemical inertness. As a result, ceramic capsule blade does not pollute the empty capsules during operation and is easy to clean. A longer service life of ceramic blades for trimming empty capsules can significantly minimize replacement frequency and assure production continuity.
