Precision Mold Fabrication

Your formulation,
made any shape.
With exact dimensions.

Synthesis is the hard part. Getting it into the right physical form shouldn't be. We machine precision molds so your compound - drug candidate, reagent, biomaterial, specialty chemical - arrives at the next step in exactly the shape it needs to be. Tolerances to ±20 microns.

Hemisphere Array

Dense grids of hemisphere cavities for bead casting, microsphere arrays, and multi-well compound layouts. Every well in the array replicates to ±20μm, so fill volume stays consistent from corner to corner.

⌀ 2–15MM PER WELL · GRID ARRAY

Channel and strip mold with liquid being dosed

Channel & Strip Array

Narrow rectangular channels for rod-form compounds, thin-strip castings, and linear reference standards - where a defined cross-section has to hold consistent along its full length.

W 1–6MM · CUSTOM LENGTH · LINEAR CHANNEL

Oval & Lentil Array

Lens-shaped cavities with a shallow, elongated profile. Suited to concentrate shaping and lentil-form solid dosage, where a wider aspect ratio measurably changes the dissolution curve versus a round well.

6–20MM MAJOR AXIS · SHALLOW PROFILE

Hexagon & Honeycomb Array

Close-packed hexagonal cavities maximize cavity density per unit area, and each well can be filled independently - a natural fit for encoded arrays, multiplexed assay layouts, and custom patterned casts.

HEX ⌀ 4–10MM · CLOSE-PACKED

Cube-well mold with square grid cavities

Cube-Well Array

Square-profile cavities with a center vent to release trapped air during casting - useful for block-form compounds, calibration standards, and reagent matrices that need a flat, stackable form.

SQUARE ⌀ 3–12MM · VENTED CAVITY

Process

From specification to cast compound.

A four-step workflow designed for scientists, not machinists. You provide the geometry and chemistry context; we handle the tooling and dimensional verification.

STEP 01

Submit Geometry

Upload a CAD file (STEP, IGES, STL) or describe your target form factor in writing. Include cavity volume, dimensional tolerances, and how the compound will be cast or dispensed.

Day 0

STEP 02

Engineering Review

Our team reviews for moldability, draft angles, and chemical compatibility with your compound matrix. DFM feedback in under 4 business hours.

Day 1 · <4hr response

STEP 03

Fabricate & Cure

Master tooling machined to ±5μm. Silicone casting process delivers finished cavity tolerances of ±20μm. Material cast, cured, and post-treated per grade spec. First articles measured on CMM before shipment.

Day 2–3

STEP 04

Inspect & Ship

Full CMM dimensional report, certificate of conformance, and material traceability documentation included. Expedited shipping available for time-critical programs.

Why Form Factor Matters

Shape isn't aesthetic.
It's functional.

For synthesized compounds, the geometry of the cast form directly determines downstream performance. A mismatched form factor can invalidate a formulation study before a single measurement is taken.

01

Dissolution & Release Rate

Surface area to volume ratio governs how fast a compound dissolves or releases. Our hemisphere, channel, lentil, hex, and cube-well arrays each produce a distinct dissolution curve - the mold geometry is part of the formulation.
02

Dosing Accuracy

Consistent cavity volume means consistent mass per unit - critical when your compound is costly, potent, or in limited supply. Tolerances to ±20μm translate directly to volume reproducibility - and therefore mass reproducibility for compounds with consistent bulk density.
03

Process Compatibility

Certain handling systems - automated dispensers, vial fillers, capsule loaders, analytical instruments - require a specific form factor to function. We match geometry to your downstream process, not the other way around.
04

Stability & Packaging

Cube-well castings stack cleanly. Hemisphere and lentil forms above ~1 mm flow freely in bulk; sub-millimetre wells may require vibratory handling. Channel and strip castings pack efficiently in linear trays. The physical form of a compound affects how it stores, ships, and is retrieved from packaging.

Every geometry dissolves differently. We mold for the curve you need.

Materials

Built in the right material for your compound.

Mold material isn't neutral - it contacts your compound directly during casting. Silicone is our core specialty, but we also fabricate in acrylic, aluminum, and stainless steel when the application demands it.
