What Is Polyurethane Vacuum Casting?
Polyurethane casting (PU or vacuum casting) gives you parts that look and feel injection-molded, at a fraction of tooling cost. Using a 3D printed or CNC machined master and RTV silicone molds, Procision delivers short runs with crisp details, tight cosmetics, and consistent fit. It’s ideal for design validation, demo-ready models, bridge-to-tooling pilots, and small-batch production.
• Fast: Typical lead time 7-14 days
• High finish: Textures, gloss, tints, and overmold effects
• Cost-effective: Production-like parts without hard tooling
Why Choose Procision for Polyurethane Vacuum Casting Services?
Match common plastics like ABS, PC, PP, PA/nylon, PMMA, and soft elastomers (Shore A-D). Options for heat resistance, UV stability, clarity, and glass-filled. Pigments can be mixed into the resin for baked-in color. Silicone overmolding available for grips, gaskets, and soft-touch features.

How PU Casting Works?
1) Master pattern via SLA/SLS or CNC → finished to cosmetic spec.
2) RTV silicone mold poured and cured, then split to create cavity.
3) Casting & cure under vacuum for bubble-free, dense parts, optional overmolding.
How Does Polyurethene Casting Compare with Other Rapid Prototyping Methods?
Polyurethane vacuum casting delivers show-ready surfaces for low volumes, beating 3D printing on finish and beats CNC on complex shapes per cost. When volumes grow and geometry stabilizes, injection molding is the next step – we’ll help you bridge.
Common Questions about polyurethane vacuum casting
Find answers to questions about Polyurethane Vacuum Casting services and how industries like medical, electronic, agriculture, and consumer products can achieve their goals by working with Procision.
What makes Procision’s PU pressure casting different?
Dedicated Ployurethane casting teams, vetted resins, controlled environments, and ISO-certified QA deliver cosmetic-grade parts on short timelines.
What's the difference between polyurethane casting and plastic injection molding?
Plastic injection molding uses a dedicated steel tool that is more expensive and takes longer to prepare, and is suitable for high volume production. PU casting is faster, less expensive, and more suited to short production runs or prototypes.
Do you provide design support?
Yes, DFM reviews covering draft, walls, textures, and material choices. We can create master patterns and advice for production migration.
What tolerances/shrink should I expect?
Typical shrink ~0.3% depending on resin and geometry. Post-machining and polish available for tighter fits and optics.
