Plastics & Overmolding Specifications

Metal + Polymer in a Single Integrated Component

Insert molding and overmolding are core to our platform — not an afterthought. Machined metal components move directly from our shop floor into the molding cell, eliminating inter-facility transfers, reducing handling risk, and keeping the entire device under one quality system.

From luer lock hubs and stylet handles to complex cannula assemblies, our tooling library and custom mold capabilities support both legacy products and new program launches.

⚡ Competitive Advantage

Pre-Validated STERIS Sterilization — Built Into Every Program

Ranfac's standardized partnership with STERIS provides a meaningful competitive advantage by reducing regulatory and operational risk for our customers while accelerating their path to commercialization.

  • Sterilization already validated and integrated into workflow
  • Customers avoid time, cost, and uncertainty of qualifying a separate vendor
  • Faster product launches with more predictable lead times
  • Scalable throughput aligned with commercial demand
  • Improved quality consistency — reduced deviations and field issues
  • Strengthens supply chain credibility for acquirers and investors
  • One partner delivers manufacturing + de-risked, commercialization-ready infrastructure

Three Ways to Partner

Choose the Engagement That Fits Your Stage

Whether you're taking a concept to 510(k) clearance, scaling a cleared design, or sourcing from our proprietary portfolio — Ranfac's platform adapts to your program.

CDMO — Concept → Cleared

Ranfac owns the entire development cycle: DFM, process validation, regulatory submissions (510(k) support, EU MDR technical files), and scaled production under your brand. Complete design history file management from day one.

Ideal for: startups, OEMs without in-house manufacturing, first-time device launches

CMO — Cleared → Scaled

You bring the design, we bring production muscle. Seamless integration into your existing quality system or extension of ours. High-volume, validated manufacturing with full traceability and real-time ERP visibility.

Ideal for: established device companies scaling production, reshoring from overseas

OEM Products

Ranfac designs and manufactures its own portfolio of minimally invasive, hypodermic-based devices for surgical and interventional applications. Available for distribution or direct purchase.

Includes: bone marrow access, hematology, general surgery. Also see Cervos Medical — a wholly owned Ranfac entity operating independently.
