What Is Vacuum Casting?

Polyurethane vacuum casting is a specialized technique for making high-fidelity copies of master patterns using inexpensive silicone molds and pourable casting resins. Copies made in this way demonstrate the same quality as plastic injection molded parts while taking only a fraction of the time and expense to produce.

Advantages Of Vacuum Casting

  • Low cost for molds
  • Molds can be made in a few days
  • Many types of polyurethane resins are available for casting, including overmolding
  • Cast copies are highly accurate with excellent surface texture
  • Molds are durable for 20 or more copies
  • Perfect for engineering models, samples, rapid prototypes, bridge to production

When to Use Vacuum Casting?

Product developers turn to vacuum casting when they need only a small volume, between 10 to 20 pieces, of production quality plastic parts while avoiding the long lead time and financial commitment of making plastic injection mold tools.

These parts are used for prototypes and display models, for crowdfunding and trade show campaigns, to test a new design for fit and function, and as a bridge to larger production volumes. Vacuum casting can also be used for end-use parts in some applications, since the pourable casting resin effectively mimics the performance of ABS, Nylon, PP, acrylic and soft TPE rubber.


The vacuum casting materials that we use at Hao Shun are two-part resins that we mix just before pouring them into the silicone mold. These resins are analogs of common plastic injection molding material and they offer comparable appearance and performance.

We can duplicate polypropylene, ABS, nylon, acrylic, and various hardnesses of soft elastomer. We can also add glass fibers to increase the stiffness of ABS and nylon for even more design options.
