Investment Casting Capabilities
At Engineered Precision Casting Co., we meet or exceed all industry standards for dimensional accuracy for investment castings as prescribed by the Investment Casting Institute. We maintain the in-house capability to perform dimensional layouts and conduct First Article Inspections to AS-9102 with a coordinate measuring machine (CMM). If tighter tolerances are required, contact a representative of our staff to determine if the requirements are within the limitations of the process.
Engineered Precision Casting Co. also maintains an inventory over 100 ferrous and non ferrous air melt alloys, procured in strict accordance with a master heat approval system for chemistry.
