Creating the molds and casting in pewter is a complex process. Read below for a little peek under the hood of this fusion of an ancient process with modern technology.
Initial Modeling
Some sculptures start as highly detailed 3D scans in order to create a faithful representation of the original form. After being digitized, 3D modeling software is used to make creative modifications that allow for casting in molten pewter. 3D prints in resin are made and sanded and refined by hand to prepare for molds.
From Model to Molten
Spin casting is a method of using inertia and pressure to produce castings from a rubber mold. In this process, a disc-shaped mold is spun along its central axis at a set speed. Pressure clamping keeps the mold in place while the molten pewter is then poured in through an opening at the top-center of the mold. The filled mold continues to spin at a steady rate as the pewter solidifies.
The Finishing Process
After the products are removed from the spincaster, each one goes through a finishing process. This consists of a treatment to achieve the desired patina – coloration, a polishing, as well as any necessary soldering by hand for more complex pieces.
