Procision Vacuum Casting
What Is Vacuum Casting?
Polyurethane vacuum casting uses silicone molds and pourable polyurethane resins to make a limited number of copies of a master pattern. They have the look and feel of those made with plastic injection molding but at a fraction of the cost and lead time.
Procision Vacuum Casting
Advantages Of Vacuum Casting
- Fast, low-cost molds: Perfect for short runs, molds can be made in just days.
- Material versatility: Simulate the properties of common plastics like ABS, nylon, PP, acrylic, or soft TPE rubber, or opt for overmolding for multi-material solutions.
- Exceptional accuracy: Achieve highly detailed parts with excellent surface textures.
- Durable molds: Create 20 or more copies from a single mold, optimizing cost and efficiency.
- Flexible applications: Ideal for engineering models, rapid prototypes, samples, bridge-to-production parts, and end-use products.

Vacuum Casting Process
Creating high-quality polyurethane vacuum cast parts involves three critical steps: making the master pattern, crafting the molds, and casting the parts.
Step 1 : Creating Master Patterns
The master pattern is a 3D representation of your CAD design, often made through CNC machining or 3D printing methods like SLA/SLS. These patterns must withstand heating to 40°C to ensure optimal performance during the process. You can provide your own pattern, or skilled experts can create one tailored to your specifications.
Step 2 : Making the Molds
Liquid silicone is used to create molds that capture every detail of the master pattern. The process begins by meticulously sanding and sealing the pattern to ensure a flawless surface. Silicone is then poured around the pattern within a casting box and cured in an oven for 12-24 hours, depending on the size.
Step 3 : Casting Copies
With the mold prepared, your choice of casting resin is poured into the empty cavity under vacuum, ensuring precise replication of the master pattern. If needed, two or more materials can be overmolded for added functionality.
