SUB-MICRON PRECISION · MEDICAL FIRSTFrom concept
From concept
to cavity,
in weeks,
not months.
Micro molds and sub-micron machining for the medical devices that don't tolerate variance. Prototyped, validated, and shipped by a team that holds ±1µm as a baseline expectation.

Typical turnaround01 / Capabilities
Three disciplines. One shop floor.
Vertical integration — molding, machining, and design under one roof — kills the handoffs that add weeks and defects. We own the whole cavity lifecycle, so your part ships faster and your documentation stays clean.
01Shot: 0.004 – 2.5 g
Micro Molding
Injection molding for parts measured in milligrams. PEEK, LCP, COC, Ultem — bio-compatible plastics, tight shot weights, and documented process windows.

02Feature: < 1 µm
Micro Machining
5-axis milling and surface grinding down to sub-micron feature sizes. Stainless, titanium, tungsten carbide, and exotic alloys for the geometries that injection won't tolerate.

Product Design
DfM, tooling strategy, and mold-flow simulation before a single cutter touches steel. We join your program at the napkin stage if you let us.

The parts in the life-saving devices.
Catheter tips, drug-delivery components, surgical instruments, diagnostic disposables — we build the interior geometry nobody sees and everybody depends on. Medical is the majority of our work because medical is where variance kills.
Sub-mm lumens, tight tips

Precise dosing geometry
Drug delivery
Single-use, repeatable

03 / People
The hands on your part.
The reason to trust a micro shop isn't its equipment list — it's who's standing at the machine. These are the people who'll be running yours.

Founder
Mark Brunsvold
Previously founded Parcus Medical (sports-medicine orthopedics) and Machined Metals (precision contract manufacturing). Ten-plus issued patents across device and tooling. Future Micro Mold exists because medical and micro-precision live at the same intersection — and nobody was running it right.

Design + Process Engineer
Anderson Brunsvold
Eight-plus years in medical-device design and process engineering. Owns your part from CAD through first-article validation. When a tolerance call has to happen at 3pm on a Thursday, you're on the phone with Anderson — not a project manager who has to ask someone else.

The bench
Ten more on the floor.
Seasoned moldmakers, machinists, and inspectors — the rest of the twelve-person shop that turns CAD into steel and steel into the part you spec'd. Every one of them chose micro because the tolerance is the point.
