Multi-Chamber Pellet Die System


Reference #: 01201

The University of South Carolina is offering licensing opportunities for using a multi-chamber pellet die system designed for improved manufacturing capability.



Currently, pellet dies are used to press KBr pellets for IR Spectroscopy and small biomaterial scaffolds used in tissue engineering applications. However, these pellet dies are not compatible with high-throughput applications, as these dies cannot produce more than one pellet at a time.


Invention Description:

The subject invention is a Multi-Chamber Pellet Die System that improves the manufacturing capabilities of the state of the art specac evacuable pellet die system by allowing for nine pellets or scaffolds to be fabricated at once. This was achieved by modifying the pellet chamber features in order to create a design optimized for high-throughput biomaterial scaffold production.


Potential Applications:

The Multi-Chamber Pellet Die System fabricates more KBr pellets for IR Spectroscopy and small biomaterial scaffolds at one time. Therefore, more pellets and scaffolds can be created more quickly and efficiently.


Advantages and Benefits:

1.       The Multi-Chamber Pellet Die System is superior to other pellet dies on the market because it increases scaffold productivity, efficiency and simplifies how pellets are made.

2.       The novel straight rod plunger design eliminates a stress concentration induced from the previous plunger design. Eliminating the stress concentration from the plunger reduces risk of potential failure after prolonged use. The cap ensures uniform distribution of applied force to each of the nine plungers.
