Ingot Manufacturing Process
RFQ from Customer
Produced from high-purity virgin elements via PML’s advanced VIM facility to ensure RFQ from Customer Alloy chemistry and ingot specifications are finalized as per application requirements.
Alloy Design/Planning
As per customer requirement mould design carried out and planned for charge preparation, charge sequences in VIM furnace. Careful selection of raw materials are the prime factor to achieve specified chemistry of an alloy.
Alloy Melting by VIM
Virgin elements are charged into the VIM furnace either in air or under vacuum, with precise adjustments made for trace element additions during melting.
Process & Quality Control
The melt is poured under vacuum into precision-engineered molds using an automatic tilting mechanism for defect-free solidification.
Primary Finishing
Post-casting processes include surface treatment, cropping, and preparation of ingots for downstream processing.
Testing & Packaging
Each ingot undergoes rigorous inspection, precision processing, and custom packaging according to the requirements.
