Medical Grade Materials

With access to the most appropriate, state-of-the-art thermoplastic and thermoset options, Seaway Plastics helps OEMs to select the right materials — those that will deliver the specific suite of performance characteristics that are required by the finished parts, products or assemblies. Our customers have the opportunity to choose from a wide range of highly engineered materials, including but not limited to:

  • ABS - Acrylonitrile Butadiene Styrene
  • POM - Acetal
  • PMMA - Acrylic
  • LCP - Liquid crystal polymers
  • LSR – Liquid Silicone Rubber
  • PA - Nylon
  • PC - Polycarbonate
  • PBT - Polyester
  • PET - Polyethylene
  • PUR - Polyurethane
  • TPU/TPE – Thermoplastic Polyurethane
  • PEEK – Polyetheretherketone
  • PEI – Ultem
  • PPE+PS – Polyphenylene Ether (Noryl)

The Seaway Advantage

There are many important advantages to selecting a manufacturing partner that is able to take ownership of every step in the process in-house — from engineering services to prototyping to fully validated production — without the need to involve additional partners or create multiple outsourcing arrangements. Specifically, for OEMs, the demonstrable advantages such a tightly integrated approach include:

  • Time savings — By streamlining the overall project management with a single manufacturing partner
  • Reduced costs — By integrating all steps with a single manufacturing partner
  • Reduced supply chain risk and administrative complexity — By minimizing the number of handoffs and packaging/shipping delays that would arise if multiple vendors were needed to complete the project and the number of business relationships and outsourcing agreements that would be needed with multiple vendors

 

Collectively, these benefits enhance reliability and reputational value — and can provide competitive advantage — for the OEM. For the healthcare professionals and patients who rely on such state-of-the-art products, the benefit of solid teamwork that consistently delivers high quality and reliability during manufacturing brings peace of mind.

To enable end-to-end project management for complex manufacturing projects, Seaway Plastics is able to manage each of these critical steps:

  • DFM (Design for Manufacturing) & Engineering
  • Tooling Design & Build
  • Plastic & Silicone Medical Injection Molding
  • Extensive post-molding operations
  • Full assemblies
  • Custom Validation & Qualification Packages
  • Sterile Kitting, Packaging & Distribution Services

Seaway Plastics has been a trusted manufacturer of high-quality components, products and assemblies for a variety of Class 1, 2 and 3 medical devices for more than four decades. To ensure a sterile manufacturing environment, its facilities have ISO 13485 Class 7 and 8 certified cleanrooms that prevent airborne contaminants as small as 0.3 and 0.5 microns, respectively, during molding and assembly operations. This ensures that finished products that are intended for use in medical, healthcare and life sciences applications meet all industry standards and regulatory requirements.

By partnering with Seaway Plastics to streamline all steps in the complex manufacturing process, OEMs are able to be more competitive, safeguard their own brand reputation and focus on meeting the needs of their end customers — healthcare professionals treating patients in hospitals, physician practices and other clinical settings. Ultimately, this team effort is critical to support the shared end objective — which is to support and enable optimal health outcomes for patients.
