Applications/Silicone Components and Sealing Solutions for Diabetes Devices

For engineering, quality, and supply chain teams building insulin pumps, patch pumps, CGMs, pens, and infusion sets.

Qualify one silicone supplier. Scale it for the life of the device.

The seals, valves, septa, and overmolded components inside your device get molded on one floor, by one engineering team, under one quality system, from a ten-piece first article through sustained high-volume production. No mid-life re-source. No second validation because your supplier ran out of room.

Where This Usually Goes Wrong

The smallest part on the bill of materials
is the one that stops the line.

A diabetes device is worn on the body, filled with fluid, and expected to run without intervention for days at a time. The parts that make that possible are a seal, a valve, a septum, an overmolded gasket a few millimeters across. They are also the parts most likely to fail an audit, hold up a validation, or trigger a line-down call at two in the morning.

Problem One

You have not picked a molder yet, and the decision is bigger than it looks.

By the time the program reaches this point, the tolerance stack is locked and the enclosure is tooled. The elastomer has to fit exactly what is already there. There is no room left to design around a supplier who cannot hold the dimension, cannot hold it lot after lot, or cannot hold it at the volume you are heading toward.

Pick for the launch volume and you will be doing this again in three years.

Problem Two

You have a molder, and you are not getting the result.

Yields drift. Lots get argued over. The tool was built for a volume you passed two years ago, and every capacity conversation ends with a quote for a new mold. Somebody has already used the phrase “we may need to dual source.”

This is the expensive problem, because the cost is not the parts. It is the requalification you are trying not to do.

Why This Keeps Happening

The industry qualifies molders
for the volume you are launching at.

That is the habit, and it is the reason the same program gets re-sourced in year three. The fix is not a better vendor scorecard. It is qualifying against the volume curve instead of the launch number.

The usual way

Qualify for launch. Re-source at mid-life.

  • Tooling sized to the launch forecast, because that is what the PO covers
  • A molder chosen for first articles and clinical builds, then outgrown
  • Capacity conversations that end in a new mold quote and a new lead time
  • A second supplier qualified under ramp pressure, mid-life, on a live device
  • Validation repeated, documents rebuilt, and an audit trail that now spans two floors
  • Years of program time spent solving the same problem twice
How we do it

Qualify once. Scale for the life of the device.

  • Cavitation strategy driven by the volume you are heading toward and your target price
  • One molder that runs a ten-piece first article and sustained high volume on the same floor
  • Capacity planned into the tooling roadmap instead of negotiated after the ramp
  • One engineering team, one validated process, one quality system across the whole curve
  • One set of documents to audit, for the life of the program
  • The requalification you never have to schedule

Low-volume, high-mix work and high-volume automated work run side by side here, under the same quality system. That is rarer than it sounds, and it is the whole reason the second qualification never has to happen.

How It Actually Works

The system that makes one qualification
hold for the life of the device.

Every part that comes off our floor is controlled by four things: a machine, a mold, a material, and a process. We take ownership of all four, so you own none of them. Here is what that looks like from your print forward.

Design for
Manufacturability

1

Geometry, parting lines, gate location, and tolerance stack reviewed before a mold is cut. Most of the cost and most of the risk in an elastomeric component is decided here.

What It Means
The risk is designed out before steel is cut.

Tooling Sized
to the Curve

2

Full tooling stewardship: requirements, design authority, DFM, cavitation strategy, vendor selection and management, validation, and transfer. Sized to the volume you are actually going to run.

What It Means
You never deal with a toolmaker.

Validation
That Holds Up

3

FAI, MSA, DOE, IQ, OQ, PQ, with full material and product traceability from raw lot to shipped carton. Built as the work happens, so it is audit-ready any day.

What It Means
You qualify once, on evidence.

Scale Without
Requalification

4

Cleanroom environment molding, automated work cells, and 24/7 operations running the same validated process at ten thousand parts and at ten million.

What It Means
You never outgrow us.
MachineLate-model liquid injection presses, cold and hot runner tooling, automated work cells, robot demolding for high-cavitation programs.
MoldStewardship end to end. Cavitation driven by your volume and your target price, not by what is on a shelf.
MaterialThe right elastomer for the wear profile, the fluid, and the bond, sourced across every major LSR supplier and compounded to spec where no catalog grade holds.
ProcessValidated, documented, and inspected on the dimensions that actually matter to function.
Proof

Consistency is the product.

Anyone can mold a good first article. Diabetes programs are won and lost on part number four hundred thousand and part number forty million.

Materials

Your spec picks the material,
not our supply agreement.

Most diabetes programs arrive with the material already specified. We work across every major liquid silicone supplier, so you are not forced into a compromise grade because of who we happen to buy from. Where no catalog grade holds the requirement, we compound to it.

The step after

Where the checklist runs out

A checklist tells you what to ask. It cannot tell you whether a specific tool, at a specific cavitation, will still be the right tool at forty million parts. That is a print-level conversation, and it takes about thirty minutes.

FAQ

Questions we get from diabetes programs.

Can IRP Medical mold silicone components for insulin pumps and CGMs?
Yes. We mold seals, valves, septa, gaskets, and overmolded components for insulin pumps, patch pumps, continuous glucose monitors, insulin pens, and infusion sets, from first article through high-volume production.
What happens when our volume grows past what the original tool supports?
Cavitation strategy is planned against your projected volume curve rather than your launch forecast, so added capacity is a planned step in the tooling roadmap instead of a new supplier qualification. The process, the quality system, and the engineering team stay the same.
What materials do you use for diabetes device components?
Liquid silicone rubber, gum silicone, fluorosilicone, conductive grades, and organic and synthetic rubber compounds. We work across all major liquid silicone suppliers and compound to custom physical property requirements where no catalog grade holds.
Are your components molded in a cleanroom?
Yes. Molding, inspection, secondary operations, and packaging are performed in controlled cleanroom environments inside our ISO 13485:2016 certified facility.
What volumes can you support?
Programs run from first article through sustained high-volume production. High-cavitation cold runner tooling, automated work cells, and 24/7 operations support the upper end.
Can you overmold silicone onto plastic or metal?
Yes. We overmold onto plastics, metals, polyimide, film, fabric, and other silicones, and we mold thermoplastic components for silicone overmolding applications.
Do you handle secondary operations, or do we need another supplier?
We handle slitting, die cutting, sub-assembly, inspection, and device packaging in house, so components arrive ready to install. Sterilization is coordinated through a qualified third party.
Can you take over an existing program from another molder?
Yes. We regularly transfer launched programs, including tooling transfer, revalidation, and requalification.
What certifications do you hold?
ISO 13485:2016 certified and FDA registered. The certificate is available on our Quality page.
