Application Focus
Pressure Die Casting Dies
Enhancing the thermal fatigue resistance and anti-soldering properties of specialized die steels to maximize shot counts.
The Challenge and Solutions
In the demanding world of Pressure Die Casting, your dies are constantly subjected to extreme thermal cycling, high-pressure metal injection, and abrasive wear. When your tooling fails prematurely, your production costs soar, and your quality suffers.
At Shital Plasma Nitriding, we help you move past these common failures by transforming the surface properties of your steel.
How We Solve Your Die Casting Challenges
| Problem Faced | How Shital Plasma Nitriding Helps |
|---|---|
| Sticking of Cast Material | Plasma nitriding creates a low-friction, chemically inert surface that prevents molten aluminum or zinc from "welding" to the die surface. |
| Heat Check Marks | By improving surface hardness and fatigue resistance, our process mitigates the formation of micro-cracks caused by rapid cooling and heating. |
| Surface Erosion | We create a robust, hardened case that resists the washing effect and erosive forces of high-velocity molten metal. |
| Thermal Cracking | Our precision-controlled atmosphere enhances the die's resistance to thermal fatigue, significantly extending the service life of complex geometries. |
| Wear & Tear | We provide a superior diffusion layer that protects your dies from the constant mechanical stress of ejection and closing cycles. |
| Corrosion of Dies | The dense, compact nitride layer acts as a powerful barrier against chemical attack from fluxing agents and corrosive alloy elements. |
