FortiPhySM Thin film tool coating from Phygen Extends Life of Precision Stamping Die Applications without Peeling

Thin film tool coating, Stamping Die Coating from Phygen.Stamping processes, such as piercing, notching, and blanking, produce high-quality precision parts at high production rates. When combined with lancing, coining, or folding operations, complex parts can be made from one piece of metal, often without the need for secondary alignment and assembly operations. Tough dies, large presses, and high impact are used to cut and bend a variety of materials. In a typical stamping line, the material is a roll of strip metal, which is sheared, blanked, and folded into finished parts. Because the metal grain structure tends to follow part contours, stamping produces stronger parts than those typically produced by machining. In addition, stamping processes usually use less coolant and generate less scrap metal.

To achieve efficient production rates, stamping operations must balance the material (alloy, hardness, thickness), machine (tonnage, stroke, feed), and tooling (dies, punches, anvils). After the press is set up and running, downtime caused by tool wear becomes the biggest roadblock to profitable production runs.

Stamping dies require precise clearances and sharp edges to maintain productive stamping rates, and to ensure that parts meet inspection requirements for size, burr height, and form radius. Soft metals such as aluminum, and complex dual materials such as brass on steel, can slow production and cause welding, galling, and tool failure. Thick or hardened materials can cause rapid tool wear.

Uncoated tools can become dull and fail quickly. Ordinary coatings can help, but the combination of high impact, heat, and tough material can overcome the adhesive strength of the coatings and peel them off in a matter of hours.

Surface engineering is critical to extending the life of precision stamping dies. High-performance FortiPhySM thin film tool coating from 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 and coating uniformity. A key benefit of FortiPhy’s nanocrystalline microstructure is its low coefficient of friction, which is lower than most commonly used polymers and polycarbonate materials. The nanocrystalline structure is free of pores, columnar structures, and inclusions, any of which could lead to cracks, corrosion, and uneven wear.
