Penna Flame Industries broke ground on an expansion at the company’s facility in Zelienople, Pa. According to President James Orr, the expansion will provide more specialized services, including the use of robots for certain selective-hardening processes. The expanded facility will include advanced flame and induction hardening systems that will enable Penna Flame to selectively harden metal parts and components of all sizes to achieve maximum durability and wear resistance. The new equipment includes an 80-inch-diameter spin flame hardening system, which will become – according to Penna Flame – the largest drop quench spinner in the world. This system will also use advanced temperature-monitoring systems to ensure consistency and repeatability. The expansion is scheduled to be completed by the end of the year.
