Injection Molding of a Polypropylene Tissue Grinder for the Research Industry

Injection Molding of a Polypropylene Tissue Grinder for the Research IndustryBiomedical Polymers, Inc. used its medical industry expertise and experience to design and then injection mold a disposable tissue grinder tip and cap for the research industry. In addition, we developed a unique process to fabricate that tissue grinder tip.
The final assembly, which was semi-automated, was completed in a white room dedicated to packaging and assembling.
We are FDA-approved, met the customer-supplied specifications and provided sterile packaging services with the use of gamma irradiation.
Our company manufactured 3 to 4 million parts in 4 to 6 weeks, then individually sealed them in .0004″ thick polyethylene bags for shipment to our customer in Gardner, Massachusetts.
