You're not just choosing a manufacturer — you're choosing the infrastructure your device will be built on for its entire commercial life. Here's why that choice matters, and why OEMs keep choosing Ranfac.
Most contract manufacturers do one thing: they machine metal, or they mold plastic, or they assemble. Ranfac does all of it — metal machining, polymer overmolding, cleaning, assembly, sterilization, and packaging — in a single 40,000 sq. ft. facility in Avon, MA. The entire value stream stays under one roof.
That means one quality system, one design history file, and one continuous flow from raw material to sterile finished good. No split programs. No inter-facility transport waste. No multi-vendor coordination. Every handoff that doesn't happen is a defect opportunity eliminated.
Ranfac has been manufacturing precision hypodermic-based devices for 137 years. That's not just a number on a slide — it's institutional knowledge embedded in every process, every fixture, and every operator on the floor.
Privately owned by the Robert M. Adler Family Trust, the company reinvests continuously in equipment, technology, and people. No quarterly earnings pressure. No PE-driven cost-cutting. Just a long-term commitment to being the best manufacturing partner in this space.
Precision manufacturing begins in Massachusetts
Began producing hypodermic needles — a capability that defines the company to this day
Expanded into laparoscopic device manufacturing as minimally invasive surgery transformed healthcare
Pivoted to single-use disposable medical devices — driving volume, consistency, and patient safety
Added cleanroom assembly, polymer molding, sterilization management — one roof, one quality system
MDSAP, EU MDR, STERIS partnership — 40,000 sq. ft., 12 processes, 20+ concurrent programs
In 2026, with tariffs, reshoring mandates, and supply chain disruptions top of mind, "single-facility Avon, MA, vertically integrated" is a material differentiator. Your entire program — from raw material to sterile finished good — stays on US soil.
No containers stuck at ports. No quality discrepancies between domestic and offshore operations. No surprise duties that blow up your landed cost model. And when your customer or investor asks "where is this made?" — the answer is simple.
Companies That Trust Ranfac
Sterilization is where many device programs hit unexpected delays. Qualifying a sterilization vendor, navigating validation protocols, and managing fragmented logistics adds months and uncertainty to your timeline.
Ranfac's standardized partnership with STERIS eliminates this. Because sterilization is already validated, integrated into our workflow, and executed through a globally recognized provider, your path to commercialization is shorter and more predictable.
What You Skip With Ranfac + STERIS
Large CMOs optimize for volume. They want your 500K-unit annual run and have little interest in your 2,000-piece launch order. Ranfac is built on lean manufacturing principles that make high-mix, lower-volume production economically efficient.
Our production system runs 20+ concurrent programs simultaneously using rapid changeovers, single-piece flow, and pull-based scheduling. We've driven significant process consolidation on key lines while dramatically increasing throughput — not by working harder, but by systematically eliminating waste, reducing WIP, and optimizing every value-adding step. We launch at your pace with low minimum order quantities and scale with you as demand grows.
Ranfac vs. Large CMOs
| Ranfac | Typical Large CMO | |
|---|---|---|
| Minimum order qty | Low / flexible | 50K–100K+ |
| Concurrent programs | 20+ | 3–5 focus programs |
| Changeover speed | Fast — built for it | Slow — optimized for runs |
| Metal + plastic + sterile | One roof | Multi-vendor |
| Lean methodology | Embedded in operations | Corporate initiative |
| Senior leadership access | Direct | Account manager layer |
Ranfac's quality system is built on lean manufacturing principles: build quality in at the source, make problems visible immediately, and continuously improve. Every process is designed to prevent defects — not catch them downstream. Operator-led kaizen, statistical process control, and error-proofing are embedded in daily operations, not annual initiatives.
We deliver high quality products with reliable, consistent results. We take ownership over efficiency requirements and are quick to recognize and rectify issues. Every project, product, and task has a responsible owner.
We quickly adjust to new products and challenges to meet market demands. Open minded to new methods of production and technology. We embrace changes, challenges, and new ideas for continuous improvement.
We provide honesty, integrity, and appreciation for each customer's individual needs. We value the impact of our responsibilities and the products we make. We foster a culture of trust and mutual respect.
Quality & lean manufacturing tools in active use:
Every new project begins with a sit-down with Ranfac's senior leadership — not an account manager. In this video, you'll hear from Harlan Adler (President & CEO), Barry Zimble (COO), Eric Kreuz (VP QA & RA), and Michael Faradie (Director of Manufacturing) on what makes Ranfac different.
These are the same people who will be directly involved in your program from day one. No handoffs, no layers.
