Description

Technical Field

[0001] This utility model belongs to the technical field of tableting devices, and more specifically, relates to a tableting machine that prevents powder leakage. Background Technology

[0002] A tablet press is a device that compresses granular or powdered materials into tablets. It can meet the requirements of the pharmaceutical industry for compressing various Chinese and Western medicine preparations and the requirements of other industries for compressing similar products.
