PTC Industries Limited has announced a key manufacturing milestone through its wholly owned subsidiary, Aerolloy Technologies Limited. The company has successfully completed the installation of a Plasma Arc Melting (PAM) furnace at its Strategic Manufacturing Technology Centre (SMTC) located in Lucknow.
The newly installed PAM furnace has an annual installed capacity of approximately 600 tonnes for the production of titanium alloy ingots. According to the company, all electrical, mechanical, and control panel installations have been completed, and the furnace is now ready for trials followed by commissioning.
Plasma Arc Melting is an advanced and specialised melting technology used globally for producing high-quality titanium and specialty alloys under a controlled atmosphere. The process uses a plasma torch as the primary heat source, allowing precise control over melting parameters, alloy chemistry, and metallurgical cleanliness. This level of control is considered critical for applications that demand extremely high material integrity, particularly in aerospace and defence manufacturing.
The installation of the PAM furnace enhances Aerolloy Technologies’ capability to manufacture titanium alloys with high metallurgical purity and consistent chemical composition. Such capabilities are essential for meeting stringent quality standards required by aerospace and defence programmes. The technology also enables efficient remelting and recycling of internal metallic scrap generated during casting and machining operations, supporting material efficiency within the manufacturing process.
In addition, Plasma Arc Melting offers flexibility in producing specialised or exotic titanium alloys in smaller batch sizes. These alloys are often not economical to manufacture using large-scale conventional melting routes, making PAM a strategically important capability for customised and high-value applications.
