Advantages of Vacuum Casting

Urethane casting has a low-cost and quick turnaround for high-quality plastc parts
compared to that of injection molding or 3D printing.Where injection molding requires 
expensive up-front investment for the machining of the mold,plastic urethane casting's 
silicone mold, or " soft tooling," is relatively inexpensive and easy to produce off the 
master pattern. Where most 3D printing processes require extensive post processing 
to get to a near-finished state, a urethane cast part comes out of the mold ready to go
with just a few minutes of clean up.Urethane casting is the go-to solution when looking 
to do on-demond prototyping or low-volume production of rigid, flexible, clear,
colored, or even rubber-such as plastic parts.It's truly a jack of all trades process.

       

       Vacuum Casting Process

           Step 1:Master building

             Masters are 3D solids of your CAD designs. They are usually made by CNC

             machining or with 3D Printing. Making Master in 40° temperature. After finish and

             inspect the masters, we will move to silicone mold making.

             Step 2: Mold making

             Casting molds are made from liquid silicone. Half-Fill the  casting box with liquid

             silicone, Heat the casting box  until silicone is fully cured and then allowed to cure 

             in an oven for 16 hours. Fill with extra silicone  liquid which is also heated & cured.

             Once dried, the mold is cut open and the master removed.

             Step 3: Make the parts

             Poured the casting resins into the empty cavity to create a highly accurate copy of

                                                                                                                                                    the original. It’s even possible to overmold with two or more materials. Silicone 

                                                                                                                                                    molds are typically good for 20 or so copies of the master pattern.

      

           

 

Vacuum Casting Materials

Hundreds of casting polymers are commercially available to reproduce any 

conceivable hardness and surface texture. It is also possible to make parts that are 

fully opaque, translucent or completely transparent depending on your application.

We are able to duplicate the product in a range of different plastic simulant materials,

UPX5210, PX223, PX521, PX527, PX223-HT, UP8150, UP8260, UP4280, UP5290,

UP5690,UPX8400,and more.Exotic materials and special requests can be purchased 

or imported if required. Please kindly ask us when in doubt.

Vacuum Casting Tolerances

The finished dimensions of vacuum cast parts are dependent on the accuracy of the 

master pattern, the part’s geometry and the type of casting material used. Generally 

a shrinkage rate of 0.15% is to be expected.
