One Precision is fully capable of handling your vacuum casting and silicone molding needs. With years of expertise in the field, we can fabricate your plastic parts to the highest standard, as well as cost-efficient and with fast turnarounds.
Vacuum casting is a great method to make rigid or flexible parts, and is ideal for high quality prototypes, function testing, concept proofing and display demos. Urethane casting parts can be made from a few to hundreds as required.
One Precision can provide up to 20 parts in 15 days or less, depending on part specification and volume.
Silicone molds are less expensive than the tooling used for injection molding, resulting in low prices.
Depending on the type of equipment used, vacuum casting can to create very large parts.
The vacuum process removes air bubbles and allows the material to capture fine details.
Coloring pigments can be added to the resin for a variety of color options.
Silicone molds can be used around 20 times before they need replacing.
Vacuum casting is a manufacturing technology that uses a vacuum to draw liquid casting material into a mold. It differs significantly from injection molding, which pushes liquid material into a mold using a screw.
The process of vacuum casting offers significant advantages, and is particularly useful for parts that have undercuts or fine details.
The process starts with a master model, which One Precision creates using one of its CNC machining centers — though 3D printing can also be used. This master model is then immersed in liquid silicone, which is cured and becomes the mold.
Once it has been cut and the master model removed, the silicone mold can be put to use. This stage involves pouring casting resin into the mold, as the vacuum removes bubbles and air pockets to ensure a smooth finish.
The resin part is then cured in an oven and removed from the silicone mold after cool down, which can be reused around 20 times.
Each cast part is an exact copy of the original master model. It’s a perfect solution for rapid prototyping and making small batches of quality parts.
