Patent number: 10260122Abstract: This invention pertains to plastic injection mold tooling, and also large forgings, formed from a low carbon mold steel having markedly increased hardening and hardenability properties in large sections as contrasted to currently available commercial products. The above attributes are obtained together with equal or better machinability and improved mold parting line wear. When manufactured in conjunction with a double melt process, this invention can improve significantly polishing characteristics and other attributes of molded parts in tooling sets.Type: GrantFiled: June 26, 2018Date of Patent: April 16, 2019Assignee: A. FINKL & SONS CO.Inventors: Louis-Philippe Lapierre, Algirdas Underys

Patent number: 10239245Abstract: A blemish free surface is formed on the cavity side of a set of mold or die blocks, said set consisting of a core side and a cavity side, by use of a softer alloy on the core side as contrasted to the cavity side so that, during plastic injection molding, the core side will wear at the parting line in preference to the cavity side whereby erosion of the set occurs on the core side in preference to the cavity side leaving the cavity side erosion free.Type: GrantFiled: February 1, 2016Date of Patent: March 26, 2019Assignees: A.
