Superalloy Powder Production (VIGA)

Using Vacuum Inert Gas Atomization (VIGA), molten alloy is converted into highly spherical metal powders with excellent flowability and uniform particle size distribution. These powders are engineered for advanced manufacturing processes where consistency and performance are critical.

Scrap Powder & Grinding Recovery

PML recovers valuable metals from alloy powders, machining grindings, and process scrap through specialized melting and refining techniques. This service helps manufacturers reduce material costs, improve sustainability, and recover valuable alloying elements that would otherwise be lost. Our recovery process supports circular manufacturing by converting production waste into reusable alloy ingots while maintaining strict quality standards.
