Abstract: This invention provides methods for forming stainless steel, single-piece, multi-chambered water faucets and fixtures with a single one-body construction. A variety of stainless steel products can be formed with a main body having an internal hollow region and a plurality of dividing chambers. The main body may be constructed using high temperature resistant ceramic cores in combination with a lost wax investment casting process. The stainless steel products formed from a single piece construction can eliminate the need for additional time-consuming manufacturing steps, such as parts welding, screw assembly, or precision press fitting. In addition, water faucets and fixtures can be provided that are substantially lead-free, non-verdigris, and non-toxic in compliance with environmental regulations and lead/toxic limits.

Abstract: Preforms for use in injection blow molding processes and such processes are described herein. The preforms can have both a body and a neck wherein the external body diameter of the preform is at most 95% of the external neck diameter. The body comprises internal and external diameters that together form a sidewall, the thickness of which can be greater than 2.0 mm. Also disclosed is a mold for the injection molding of the preform described above.
