RT Manufacture Vacuum Casting Service FAQ

Do you provide vacuum casting drawing design services?

Hello, RT only provides silicone mold processing services and has not yet provided parts drawing design services.

How durable are silicone molds used for vacuum casting?

Silicone molds have good flexibility. During the demolding process, silicone molds are less likely to damage parts than rigid molds. It can adapt to a certain degree of part shape changes and can be reused many times. Generally, silicone molds can be used about 15 to 20 times under normal use conditions.


For example, when casting some plastic products with complex undercut structures, silicone molds can smoothly remove parts through their elastic deformation during demolding, and after multiple such operations, the mold can still maintain its basic shape and performance.

What are the limitations of vacuum casting?

The vacuum casting process has certain shortcomings. R&D personnel need to use mature design methods to ensure that a sufficient draft angle is set to allow the parts to be demolded smoothly. Similarly, special structures such as undercuts, deep ribs, and bosses should be avoided because they are easy to damage the softer silicone mold when the mold is opened and closed.

How cost-effective is vacuum casting?

Vacuum casting, also known as urethane casting, has cost advantages for small batch production. Compared with traditional die casting or sand casting, vacuum casting does not require a large amount of special equipment investment. Its mold cost is relatively low, especially when manufacturing some parts with complex shapes but small batches. For example, when manufacturing customized art sculptures or limited edition car parts models, vacuum-casting molds can be made relatively quickly and cheaply.

How accurate is vacuum casting?

Vacuum casting is a casting process performed in a vacuum environment. In this environment, liquid materials can fill the mold cavity more smoothly. Since there is no air obstruction, its accuracy can be high. Generally speaking, the dimensional accuracy can be controlled within ±0.1 - ±0.3mm for some small and relatively simple parts.


For example, when manufacturing some small aerospace parts, vacuum casting can accurately replicate complex internal cooling channels and thin-walled structures. These structures' wall thickness accuracy is very high, and vacuum casting can keep the wall thickness error within a small range to ensure the parts' performance.
