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.

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. Spheres, discs, and cylinders 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

    Flat-base discs stack. Spheres above ~1 mm flow freely in bulk; sub-millimetre spheres may require vibratory handling. Pellets pack efficiently. 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.

Primary · Silicone
Platinum-cured silicone

Our core material. Non-reactive, non-stick, and biocompatible. No tin catalyst byproducts - significantly reduced contamination risk versus tin-cured grades for mass spec, bioassay, and in vivo work. Available Shore 10A–60A and fluorosilicone for solvent contact.
