This page is a stage-by-stage map of how a medical device part moves from design intent to repeatable production. Immicron works as a medical device components manufacturer for design engineers, OEMs and contract manufacturers, applying the same custom-fabrication model across the industries it serves. Teams shortlisting custom medical component suppliers can work down the four gates below to find the process that fits the stage their program is in, then bring a drawing, material and volume expectation to a quote request.
Each gate answers one question and hands the part to the next. Quality and inspection are not a gate of their own — they run underneath all four, which is why the band sits below the timeline rather than inside it.
Lock the design intent, the feature geometry and the accuracy targets before anyone picks a process.
Open Design & DFMBuild one-offs and clinical-trial small batches with CNC machining, 3D printing, vacuum casting and sheet metal.
Open Prototype & Clinical BatchMove a frozen design into injection molding so the part becomes repeatable rather than merely correct.
Open Tooling & Scale-UpRun bulk volumes and replacement components with reproducible quality and inspection behind them.
Open Production & OEM EfficiencyRigorous inspection methods are used to check dimensional accuracy and material integrity on the parts produced at every stage, so the evidence you need at Gate 04 starts being collected at Gate 01.
Nothing downstream can be chosen well until the design intent is written down. This gate is deliberately free of process claims, because its output is the brief that every later gate works from.
Every gate that follows is a consequence of a decision made here. Before a process is selected, the component needs a settled purpose: what it has to do, which features carry that function, and how closely those features have to match the parts around them. Immicron's medical work is framed around the fabrication of complex geometries with tight tolerances, so geometry and dimensional accuracy are the two topics that shape the rest of the program.
Workflow integration belongs in this gate too. When your own development process and the fabrication steps are joined up early, fewer assumptions get baked into a design that later has to be tooled, inspected and released. Bring your milestones, review gates and release dates into the first conversation rather than the last.
This is the stage the medical device product page describes directly: prototyping and small-batch production for clinical trials. At this gate the useful question is not "which process is best" but "which process answers the question we are asking right now".
Buyer decision: are we still changing the design?
Buyer decision: does this batch need to behave like final production, or only work?
Injection molding is deliberately held back to Gate 03. Tooling commits you to a frozen design, and at this stage the design is usually still being validated — the product page lists injection molding as the route to high-quality medical device injection molded parts with consistent accuracy, which is a scale payoff, not a prototype one.
Once the design stops moving and the volume justifies it, the program shifts from making parts to making them repeatably.
Injection molding becomes the primary process. The payoff is repeatability across a run rather than the cost of any single part, and the tolerance conversation moves from "can this be machined" to "can this be molded and held".
Surface finishing is applied with production intent — anodizing, sandblasting, passivation, electroplating, chrome plating or painting — matched to the environment the component will work in.
Buyer decision: hold at Gate 02 until the design is frozen and the volume case is real.
Production is where the operational claims are actually tested: reproducible quality, high repeatability, improved yield rates, reduced material waste, improved production throughput and reduced time-to-market.
The product page positions Immicron as a custom medical component supplier supporting bulk medical device manufacturing efficiently — that is the volume track for OEMs and contract manufacturers who have already frozen a design.
At this gate the lever is not creativity, it is stability: consistency between batches, inspection records that support release, and a finishing schedule that does not become the bottleneck.
Buyer decision: has repeatability been demonstrated across more than one run?
The product page describes a second production scenario: maintenance and replacement components for devices already deployed in hospitals and clinics. Here the target is matching an existing part rather than launching a new one.
CNC machining and sheet metal processing are usually the shortest route, since they do not require new tooling. The finish has to be compatible with the device it is going back into.
Buyer decision: do we have the geometry and finish data needed to reproduce a part already in service?
Quality is the through-line of the map, not a stage you arrive at. The same four checks apply whether you are buying one prototype or a production run.
Ask for the inspection documentation you actually need at each gate. On a prototype, a dimensional report on critical features may be enough; on a bulk run, the release criteria should be agreed before the first article is cut.
Match your situation to a stage, a process shortlist and the decision you are really making at that point.
| Your situation | Gate | Processes to shortlist | Decision you are making |
|---|---|---|---|
| Single engineering prototype to test form and fit | Gate 02 | CNC machining, 3D printing | Is the geometry good enough to keep, or does it change again? |
| Small batch for a clinical trial | Gate 02 | CNC machining, vacuum casting, sheet metal processing | Do we need trial-representative parts or just functional ones? |
| Design frozen and volume committed | Gate 03 | Injection molding plus surface finishing | Does the volume justify tooling against continued low-volume work? |
| Ongoing bulk production for an OEM program | Gate 04 | Injection molding at volume, with inspection behind it | Is batch-to-batch repeatability documented well enough to release? |
| Replacement or maintenance part for a deployed device | Gate 04 | CNC machining, sheet metal processing | Can the existing geometry and finish be reproduced faithfully? |
| Component that must survive a demanding environment | Gate 01 → 03 | Finish selection: anodizing, sandblasting, passivation, electroplating, chrome plating, painting | Which finish delivers the corrosion resistance or biocompatibility the device needs? |
No numeric tolerances, material grades, MOQs or lead-time figures are published on the medical device page. Bring the values your program actually needs — critical dimensions, material, finish and expected volume — into the quote request so they can be confirmed against your part.

Tell us where your part sits today — a concept, a trial batch, a frozen design or a running production program — and the quote comes back matched to that stage.
Send the drawing, the material expectation and what the part has to prove. CNC machining, 3D printing, vacuum casting and sheet metal processing are available for early-stage builds.
Modular design principles support versatile customization for OEMs and contract manufacturers, from a modified standard part through to a program-specific component.
For bulk medical device manufacturing or maintenance components for devices already in service, share the volume expectation and the inspection documentation you need.
it covers four stages of one program: design and dfm, prototyping and clinical-trial small batches, tooling and scale-up, then bulk production and oem efficiency. quality and inspection run across all four rather than sitting at the end.
cnc machining, 3d printing, vacuum casting and sheet metal processing serve the prototyping and small-batch stage, where the design is still being validated and tooling is not yet justified.
injection molding is listed as the route to high-quality medical device injection molded parts with consistent accuracy, so it belongs to the scale-up gate — once the design is frozen and the committed volume justifies tooling. confirm the volume case with the supplier before committing.
the program covers various metals and plastics suitable for medical applications, with no material grades published. finishing options are anodizing, sandblasting, passivation, electroplating, chrome plating and painting, selected for corrosion resistance or biocompatibility where the device needs it.
no numeric tolerances, material grades, moqs or lead-time figures appear on the medical device page. bring the critical dimensions, material, finish and expected volume for your part into the quote request so they can be confirmed specifically for your program.
yes — the product page describes maintenance and replacement components for devices deployed in hospitals and clinics. cnc machining and sheet metal processing are usually the shortest route because they avoid new tooling, and the finish should be matched to the device the part returns to.
