Superplastic forming for titanium implant enclosures

摘要

A titanium alloy metal sheet is provided and heated to a superplastic forming temperature. A die has a plurality of housing forming areas each corresponding to one of the medical device housing portions. The heated titanium alloy metal sheet is forced onto the die and over each one of the plurality of housing forming areas, thereby superplastically forming a workpiece comprising a plurality of integrally formed implantable medical device housing portions.

主权项

1. A method of manufacturing a plurality of titanium alloy implantable medical device housing portions, comprising the steps of:
a) providing a titanium alloy metal sheet; b) heating the titanium alloy metal sheet to a superplastic forming temperature; c) providing a die comprising a plurality of housing forming areas each corresponding to one of said housing portions; and d) forcing the heated titanium alloy metal sheet onto the die for engaging each one of the plurality of housing forming areas, thereby superplastically forming a workpiece comprising a plurality of integrally formed implantable medical device housing portions.
