High Endurance FortiPhySM Help Metal Forming Companies Keep Tools Running Longer
Metal
forming processes such as cold-rolling and cold-drawing produce
high-quality precision parts at high production rates. Unlike
machining and progressive stamping, in which metal is removed,
metal forming processes use tough dies and large presses to
apply high pressure to reform metal. Materials, such as metal
sheets, wire, or bar stock, undergo plastic deformation as
they are formed into finished parts. Because the grain structure
of the metal tends to follow part contours, metal forming
produces stronger parts than those typically produced by machining
the same part from a solid. In addition, metal forming processes
use less coolant and generate less scrap metal.
Metal forming dies require precise clearances to ensure
that metal flows properly during forming operations. Friction
must be overcome as quickly as possible and remain low during
the entire operation. High pressure forming, such as deep
drawing, can generate intense heat and cause welding, galling,
or seizure. Abrasive wear can be a big problem with some materials,
such as hard cold-forming wire.
Uncoated tools can fail quickly. Ordinary coatings can help,
but the combination of high pressure, heat, and abrasive material
can overcome the adhesive strength of the coating and peel
it off in a matter of hours.
Surface engineering is critical to extending the life of precision dies. High-performance FortiPhySM PVD tool coating by Phygen can help manufacturers keep critical tooling running longer. FortiPhy UltraEnduranceSM coating is applied using a patented process that ensures an unprecedented level of process control, coating uniformity, and adhesion. A key benefit of FortiPhy’s nanocrystalline microstructure is its low coefficient of friction. The nanocrystalline structure is free of pores, columnar structures, and inclusions, any of which could lead to cracks, corrosion, and uneven wear.
