Micro Materials: This device is molded from PEEK (PolyEther Ether Keytone).
Micro Features: 0.022″ (0.56 mm) ID Passage for the implant.
Description: This PEEK implant is used as a soft tissue-bone anchor device in orthopedic or minimally invasive reconstructive surgeries. The PEEK device’s unique .007″ micro rib design with zero draft was highly important to the design functionality as this would serve as the main region for suture compression. MTD’s challenge was to not only create this feature in the tool steel with adequate venting but also ensuring through the use of micro mold flow that the geometry could be completely filled.

Medical micro injection molding is what we do. And all we do.
We’ve made millions of micromolded medical parts. We have years of expertise in problem-solving the most challenging micro part designs, including ones that require high-temperature micro injection molding with materials like PEEK (polyether ether ketone) and other thermoplastic polymers.
PEEK is a permanent resin popular for orthopedic and sports medicine applications requiring strength and durability. Successfully micromolding PEEK, however, presents several challenges.
For example, precise temperature control is critical so the part can be molded and de-molded without distortion. We understand how to optimize the polymer’s flow path and maintain quality control throughout the process. We’re also experienced in overmolding and “undermolding” with PEEK.
