Spin Casting, how does it work?

How the spin-casting Machine works


The Process

Step 1
The mold for the production run is created by spacing the prototype in high heat resistant rubber silicone. A rubber silicone mold is placed into the frame and then the prototype part is strategically placed into the mold for even distribution and efficiency.

Step 2
Alignment accuracy is ensured by the placement of special pins around the rim of the compound before securing each half of the mold in the frame. The purpose of these pins is to maintain alignment of the mold. Mold release is sprayed onto the rubber silicone for easy separation of the mold after pressure has been applied from the vulcanizer. (see step #3)

Step 3
The framed mold is placed between precision ground heat plates, which evenly distributes heat while manual jacks are set to produce the neccessary pressure. After approximately one hour the Vulcanizing process is complete. The mold is then removed from the Vulcanizer using heat resistant gloves and allowed to cool.

Step 4
Gates are then carefully grooved into the mold to assure that maximum flow of molten material will reach every cavity within the prototype impression. This step is neccessary for proper distribution of metal throughout the prototype, eliminating pockets of air.

Step 5
The mold is then secured in the Spincaster which can accommodate any mold thickness up to four inches without the need for spacers. The Spincaster can also accommodate mold and frame diameters of 9", 12", 15", and 18".

Step 6
The molten material is poured into the Spincaster funnel. The centrifugal force sends the molten alloy into even the most intricate mold patters. This ensures great detail within the prototype mold and will eliminate unnecessary finishing for most parts.

Step 7
In only seconds, the production parts are set and readied for easy removal. The special pins allow for the efficient assembly and realignment of the mold for future use. THIS PROCESS TAKES TWO HOURS - FROM START TO FINISH!
