EQUIPMENT RANGE · PLASMA NITRIDING
ASPN: active-screen plasma nitriding.
Superior surfaces and tool life: uniform, low-distortion treatment for industrial batches.
NOVA VacoraASPN plasma nitriding enquire
Active-screen plasma nitriding in a bell furnace: plasma is generated at the active screen, while parts carry only a low bias voltage. This provides uniform temperature without arcing or distortion and allows mixed batches without complex masking. Four standard sizes, with custom sizes on request.
- 4
- Standard sizes, Ø 800 to Ø 1,500 mm
- 150
- kW maximum plasma power
- NADCAP
- Optional aerospace package
Who it is for and why
Who it is for.
Heat-treatment companies, tool and mould makers, automotive and aerospace suppliers, medical technology: stamping, forging and extrusion tools, die-casting and plastics moulds, taps, and components such as valves, gears and crankshafts.
Why ASPN plasma nitriding.
- Uniform temperature throughout the batch, no hollow-cathode effect
- Low cathode current on parts: no arcing, no distortion
- Nitriding with and without a compound layer, nitrocarburising, post-oxidation
- Mixed batches and simple loading, less operator dependence
- Low gas and electricity consumption, low operating costs
