How much does urethane casting cost?

The price range for the urethane casting prototypes is $5 to $200. Each silicone mold can make up to 25 copies; the more you make, the cheaper the piece price.

Can you cast silicone in a urethane mold?

Yes, we can make silicone parts with urethane casting process.

What is the difference between urethane casting and injection molding?

Urethane molding uses polyurethanes to simulate an injection mold grade production plastic, whereas injection molding uses the actual production plastics.

Why would you choose urethane casting over 3D Printing?

One key difference between urethane casting and 3D printing is the material quality. Urethane casting uses stronger materials that better match those found in real products. It also tends to have a better look and feel. If you care about how the material performs and looks, urethane casting is a great option.

What are the reasons for selecting urethane casting instead of injection molding?

When considering production methods, it is crucial to choose between urethane casting and injection molding. Urethane casting is particularly beneficial for low-volume production runs. For quantities as low as 50 pieces, urethane casting offers cost-effective solutions without the hefty upfront tooling expenses associated with injection molding. Customers prefer urethane casting as a preliminary step to refine their designs before committing to the more expensive injection molding process.

Master Pattern Creation: First, we create a master pattern of your part using 3D printing. We use high-resolution methods like CNC machining or SLA 3D printing to make smooth, detailed parts. The master pattern is then hand-finished for the best surface quality before moving on to the mold-making process.

Making the Mold: Next, place the master pattern inside a mold frame, then pour liquid silicone around it. The silicone hardens around the pattern, capturing all its details. After it cures, the mold is split into two halves, and the master pattern is removed, leaving a cavity shaped like the part.

Cast Urethane Molding: In the final step, liquid urethane or silicone is poured into the silicone mold. The mold is placed in a chamber to remove air bubbles from the material. For opaque parts, the chamber is pressurized, and for clear parts, a vacuum is used to improve clarity and reduce bubbles. After curing, the mold is opened, and the finished part is removed. This process is repeated to make as many parts as needed.
