Injection molding method and apparatus with base mounted feeder
Patent 6789603 Issued on September 14, 2004. Estimated Expiration Date: February 2, 2024. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
An injection molding apparatus contains two chambers and a melt feeder. The melt feeder is mounted to the machine base. The liquid metal in the melt feeder is maintained below the level of an opening to a driving mechanism attached to an upper of the two chambers.
