Welcome to your go-to experts in innovative prototype casting. Our specialty in the production Prototype Casting Inc. is possible because of our dedication to being a leader in the competitive field of prototype casting. We are with our customers every step of the way including part development, choosing materials, producing designs and machining to achieve accurate and optimal casting. Our method of casting is outlined below.
How a cast is made:
- A pattern of the object to be cast is made. This can be done in just a few hours with no tools.
- This pattern is prepped for the casting process by being coated in wax. This wax allows for the cast to be easily removed and without damaging the part.
- The waxed pattern is then placed in a sprue where it can facilitate pouring.
- The sprue is first dunked into a slurry of ceramic material.
- After the first coat, the sprue is drained and dipped into a fine ceramic sand. This step is repeated with progressively coarser ceramic sand several times.
- Now that the shell has been built, the sprue is put into extreme heat to remove the initial wax seal at temperatures between 1600° and 2000°.
- The heated sprues are removed from the furnace and immediately poured.
- The poured out shells are set out let cool and the shell is separated from the sprue. Parts can now be cut from the sprue.
While the prototype casting process can be simplified into just a few steps, this is a procedure that must be performed by trained and experienced engineers and machine operators. Our team at Prototype Casting Inc. is prepared to handle your most delicate and complex designs. If you have specific inquiries or concerns about your needs, please contact us!
