Design of a Multi-Spring Floating Die Compaction System for Plastic Powders
This paper describes the design and use of a rig to simulate double-ended compaction of powder into a solid mass. The design uses three linear levels of springs in a novel way to model the load-deformation characteristic for the material being compacted. It was found that this design worked extremely well, producing compacts which had properties similar to those expected from a true double-ended compaction rig. The design of this rig thus provides an economic way of compacting powders into a solid mass using a single hydraulic ram but with the benefits of the double-ended compaction mode.
