MTD Micro Molding is built for high performance in only one area: the micro molding of advanced medical products. From handling materials to packaging, everything is done by people whose sole focus is medical micro injection molding.

Medical Micro Molding is what we do. And all we do.

MTD custom-crafts ultra-precision molded components that meet the exact requirements of the medical device industry. Other companies dabble in micro medical devices for the medical market, but we focus 100% on micro medical device design and production.

MTD is a ISO 13485 micro molding contract manufacturer certified with in-house tooling, unparalleled bioabsorbable molding expertise, and state of the art equipment – all under one roof. Our dedicated focus on bioabsorbable and drug delivery micro molding ensures successful delivery of complex custom products that nobody else can produce.

Bioabsorbable Micromolding Expertise

We help our strategic partners develop those new solutions, exploring and producing tiny, delicate, and intricate components required for specialized surgeries, bioabsorbable devices and implant devices. As a globally recognized leader in bioabsorbable polymer molding, MTD believes a successful bioabsorbable micromolding project will meet the following criteria:

  • premium part quality from a robust molding process window,
  • less invasive devices with increased precision and capability,
  • superior post-mold mechanical and functional properties,
  • consistent and minimal post-mold IV loss, and
  • highly capable critical dimensions.

Key Markets & Applications for Bioabsorbable Medical Micromolding

  • Orthopedic/Orthopaedic
    • Sports Medicine (ex. hard and soft bone anchors, soft tissue fixation, knotless suture anchors)
    • Reconstructive Devices (ex. craniomaxillofacial, plastic surgery)
    • Spinal Implants (ex. spinal degenerative disease therapies)
    • Soft Tissue/Arthroscopy (ex. suture anchor, interference screws – knee, shoulder, hip)
    • Fixation (ex. hernia mesh screws, staples, tacks, plugs)
  • Drug Delivery (ex. bioabsorbable pharmaceutical delivery vehicles/carriers, drug delivery implants, bioabsorbable polymer drug-eluting implants – drug/polymer coated or drug/polymer compounded to modulate drug release)
  • Cardiovascular (ex. structural heart disease therapies, suturing devices, catheter ablation tips)
  • Closure (ex. wound/port closure; i.e. subcutaneous absorbable fasteners, anchors, staples, suture devices, femoral artery closure)
  • Neurological (ex. brain/neural implants)
  • General Surgical (ex. surgical clip, MIS therapies, catheter tips)
