ABSTRACT:
A sink strainer assembly includes a hollow strainer body, a molded hollow plastic nipple which is a force fit within a lower hub section of the strainer body and a filtering screen assembled to the nipple in the hub section of the strainer body to prevent oversized materials from passing into drainage conduits connected to the strainer assembly. In the method of this invention, the strainer body is formed from stainless strip by a deep drawing operation, and the filtering screen is cut, stamped or otherwise separated from the base of the lower hub section. This separation can occur as part of a progressive die or as a separate operation.
