Lost Wax Precision Casting - MIM (Metal Injection Molding)
Silicone Rubber Casting
Silicone Rubber Casting
What is Silicone Rubber Casting?
Silicone rubber casting method uses molds made by silicone rubber instead of metal molds in the lost wax process.
Features of our Silicone Rubber Casting
Quantity
Small lots (less than 100 pieces)
Shape
Approx. Max Size 60 cubic mm, Complex shapes that are difficult to create with molds can be produced
Material
Various types of steel, stainless steel, and aluminum
Casting surface
Dependent on the accuracy of the 3D printed model, stacking is visible.
Accuracy
Low precision because it depends on the precision of the 3D printed model. If accuracy is required, additional machining may be necessary to achieve the required dimensions.
Silicone Rubber Ccasting Manufacturing Process
1. 3D printing
Create resin model by 3D printer
2. Silicone rubber mold making
Pour silicone into the frame with the model attached. After the silicone hardens, cut open the mold and remove the model.
3. Wax molding
Inject wax into the silicone mold.
4. Plaster filling
Frame the wax tree and pour in the stirred plaster. When the plaster hardens, the plaster mold is complete.
Notes on Digital Casting / Silicone Rubber Casting
1. Dimensions
The dimensional precision required for industrial products may not be achieved since it depends on the accuracy of the 3D printed model. As a countermeasure, additional machining may be necessary to achieve the required dimensions.
2. Casting Surface
Surface roughness also depends on the accuracy of the 3D printed model, so it is not equivalent to lost wax products.
3. Materials
Not all 3D printed models are suitable for use in digital casting. Some materials may not work well due to issues like residue or expansion during combustion.
