Design and Optimization of Tablet Press Machine

Abstract

The preferred drug delivery system today is represented by tablets, which are manu- factured using high speed rotary presses where the powder material is compressed in a die between rigid punches. Karnavati Engineering manufactures di erent types of the tablet press machine and the rotary tablet press machine UNIK 1 FC is one of them. The objective of the project is to relook into the design of the machine and to reduce the weight of machine. 3D CAD model of rotary tablet press is prepared in SolidEdge 19.0. De ection and stresses at various critical points are determined using ANSYS 12.0. Redesign and optimization for the di erent components of machine is carried out considering the Tablet Speci cation Manual (TSM) standards at the same time keep- ing comparable machine structure accuracy and productivity. To reduce the weight of the machine topology and shape optimization is carried out with OPTISTRUCT software.
