Multi-tip Punches and Their Impact on Compression Forces: A Case Study

Multi-tip punches are a cost-effective means of increasing tablet output without adding additional tablet presses. Multi-tip punches follow a similar principle as a single tip tool for the rotary tablet press, but operating techniques differ. Two common multi-tip tool configurations for B and D tooling are assembled and solid type tools. When choosing which configuration best fits… Read More
