US Patent:

20040051026, Mar 18, 2004

Filed:

Sep 18, 2002

Appl. No.:

10/247109

Inventors:

Robert Flynn - Littleton CO, US

International Classification:

C25D001/10
C25D003/12
B29C033/38
B05D001/36

US Classification:

249/116000, 427/402000, 427/133000

Abstract:

A mold construction is provided having a layered configuration including a substrate or mold core preferably of ampcoloy, an intermediate or primer coat preferably of electroless nickel, and an outer mold surface layer made of a high strength metal preferably of titanium. The mold construction is particularly advantageous for use in molding glass objects. The electroless nickel undercoat or primer coat serve to adhere the softer ampcoloy substrate to the high strength outer layer of titanium alloy. The electroless nickel also provides some elasticity for the outer layer of titanium alloy layer to reduce cracking and flaking of the titanium alloy. The layer of titanium alloy provides good strength and durability to withstand abrasive contact with the molten glass, while the ampcoloy still facilitates high thermal conductivity for reducing mold cycle times.
