Custom Mold Design, Mold Building & Manufacturing of a Medical Biopsy Marker

At Marman Industries, we offer vertically integrated design, mold building, injection molding, assembly, and packaging services that build value into the manufacturing process. The product highlighted here is an instrument which is used to implant a marker at the biopsy site after a biopsy is taken. Because this product is used on patients in the medical industry, the customer sought out a manufacturing partner with ISO 13485 certification and FDA registration. From the outset, we took on the project management role, which included providing engineering and design assistance to ensure that all parts would meet customer requirements as well as all regulatory compliance standards.


Once designs were finalized, molds were designed and built to manufacture the product in accordance to the customer's specifications. Having these abilities in-house allows us to have complete control over the fabrication process and shortens the time from development to production. ABS, polycarbonate, and polypropylene molded components were assembled under magnification to ensure precise assembly. The plastic sub-assembly components were injection molded to precision. Tensile testing was also performed to verify material strength.

The final assembly was packaged and sealed in preparation for shipping to a sterilization provider. The final design was delivered to the customer. We manufacture approximately 200,000 of these biopsy markers per year with weekly deliveries to the customer via a Kanban system.
