Silicone Mold Casting
Vacuum Casting
High-quality, sturdy, and accurate parts using silicone rubber molds and thermoset polyurethane resins. Production-grade quality at a fraction of injection mold tooling cost.
Process
How Vacuum Casting Works
Master Pattern
A high-quality master is created via SLA 3D printing or CNC machining, capturing every detail of the final part.
Silicone Mold
Liquid silicone rubber is poured around the master, cured, and split open. The resulting mold captures surface texture down to micro-level detail.
Vacuum Casting
Thermoset polyurethane resin is mixed, degassed, and poured into the silicone mold under vacuum — eliminating air bubbles for flawless parts.
Demolding & Finishing
Parts are carefully removed, trimmed, and finished. Painting, texturing, and assembly available as needed.
Materials
10+ Urethane Resins
Thermoset polyurethane resins that simulate the properties of production thermoplastics — from rigid ABS to flexible rubber.
ABS-like
Tough, impact resistant, good for functional parts
PP-like (Polypropylene)
Flexible, chemical resistant, living hinges
PC-like (Polycarbonate)
Transparent, high impact, heat resistant
Acrylic (PMMA-like)
Clear, optical quality, display parts
Rubber (Shore 45A-85A)
Flexible, soft-touch, seals and gaskets
High Temperature
Withstands elevated temperatures for under-hood and industrial
Nylon-like
Strong, wear resistant, moving parts
Nylon Glass-Filled
Enhanced stiffness and thermal stability
FR-grade (Flame Retardant)
UL94 V-0 rated, electrical enclosures
Food-grade
FDA compliant for food contact applications
Advantages
Why Vacuum Casting
Production Quality
Parts rival injection molded quality in appearance, feel, and function — without the tooling investment.
Fraction of Cost
Silicone molds cost a fraction of steel or aluminium injection molds, making it ideal for 1-50 unit runs.
Rigid & Flexible Parts
From rigid ABS housings to Shore 45A rubber gaskets — both in the same mold if needed (overmolding).
Small to Large Format
From tiny switchgear components to full-size automobile bumpers. No size limitation holds us back.
Fine Surface Detail
Silicone captures every detail of the master — textures, lettering, logos, and micro features.
