Materials & Coatings

Core-rod tooling requires material strength and surface protection to maintain rod alignment and consistent bore formation during compression. Proper material selection helps prevent premature wear, deflection, and dimensional variation.

Punch Material Options

Selecting the appropriate tool steel supports structural stability and long-term performance in core-rod applications.

S7 Tool Steel: Shock-resistant grade providing strength and durability under compression.
S7 ESR: Refined structure for improved fatigue resistance and extended service life.
D2 Tool Steel: High wear resistance for abrasive formulations.
440C Stainless Steel: Corrosion-resistant option for reactive or moisture-sensitive materials.
Carbide Components: Recommended where increased wear resistance is required.

Tooling Coating Options

Surface treatments reduce friction, protect rod surfaces, and help maintain bore accuracy.

Hard Chrome: General-purpose wear and corrosion protection.
Chromium Nitride (CrN): Enhanced hardness with anti-stick performance.
Titanium Nitride (TiN): High hardness coating for abrasive environments.
Diamond-Like Coating (DLC): Wear-resistant surface treatment to extend tooling life.
