The flowing forms of the TFI Lavanto® lavatory bowl and the CORIAN® Lounge Chair by Matthew Hoey (featured in
our last issue) began life as sheets of CORIAN®. Breakthroughs in three-dimensional thermoforming techniques
for CORIAN® make it possible. The By using a vacuum press, preheated sheets of CORIAN®, ¼- to ½-inch thick (6 to 13mm) can be thermoformed around three-dimensional moulds. A vacuum membrane applies force evenly across the preheated sheet to shape it around the mould. |

Either male or female moulds can be used. For deep shapes, a male mould can reduce the risk of wrinkling. But because a deep or steep
piece will shrink around a male mould as it cools, it may stick to the mould unless a 5º (minimum) release angle is incorporated into the
design.

Helper pieces may be useful in the moulding process to do some initial shaping of difficult contours before the vacuum membrane is
activated.

A property placed perimeter frame helps the vacuum membrane conform to contours of the mould without deformation or wrinkling on outer
edges.

Sensuous seamless curves...from a sheet? It's true.
manufacturing processes for both of these products are proprietary and far
too complex to explain on a single page. But here are some of the basics:
