These components are cast using our proprietary process, designed to improve wear and corrosion resistance while offering glass-makers thermal conductivity ranging from 18 to 37 (Btu/sq. ft./ft/hr/°ft) at 850°F.
Eballoy 700® - Excellent bronze moulding alloy with 15% nickel providing superior wear and corrosion resistance for Neck Rings and bottom plates.
Eballoy 690® - Time tested standard for bronze bottle moulds where the operating environment consists of severe wear conditions at elevated temperatures.
Eballoy 728® - A bronze alloy very similar to our Eballoy 700 with a higher Silicon content for increased machinability. This alloy is widely used in both Neck Ring and mould applications.
Bronze Neck Rings are supplied in an as cast or semi-machined condition with the mating faces and ends milled, and one or more of the bands turned. Although typically held much tighter, our in-house machine shop works to a "half on half" tolerance of .002 (.05mm) and "shake" is held within .002 (.05mm). Other bronze bottle mould components are offered in the "as cast" condition within typical sand casting dimensional tolerances.
Nickel Inserted Neck Rings:
Upon request, Erie Bronze also offers our high quality bronze Neck Rings with a nickel insert for increased life in the finish area of the ring. The insert is available in Rockwell C hardness ranging from 30 to 44.
