High Temperature Lamination Vacuum Pan

Disclosed is a fixture to be used when a vacuum is needed during high temperature lamination.

This fixture is designed to utilize a metal seal between a pan, diaphragm and lock ring. A recessed pan with matching diaphragm and lock ring are held together with bolts. With these in place a vacuum is drawn thru a hole in the pan.

To vacuum laminate, the lay-up is placed in the pan. A soft metal seal is placed around the top of the pan. This seal could be aluminum. Next, a thin metal diaphragm is placed over the pan and lay-up. The diaphragm could be stainless steel. The lock ring is positioned over the diaphragm and bolted to the pan. When a vacuum is pulled, the diaphragm is pulled down around the lay-up. The fixture is dimensioned so the lay-up is higher than the top of the lock ring. This will allow for pressure contact during lamination.

This will allow for pressure contact during flat bed press lamination. The fixture can be used for autoclave lamination. During autoclave lamination, the lay-up need not be above the height of the lock ring.
