TiN Coated H13 Core Pins for Die Casting Molds

Product Overview

TiN Coated H13 Core Pins are high-performance die casting mold components designed to form internal holes, cavities, and detailed features in metal cast parts. These precision pins are manufactured from H13 hot-work tool steel and enhanced with a Titanium Nitride (TiN) coating, providing improved wear resistance, surface hardness, and reduced friction during high-pressure die casting operations.

The TiN coating significantly improves the durability of core pins exposed to molten metal and repetitive thermal cycles. This makes them ideal for aluminum, zinc, and magnesium die casting molds, where long service life and stable dimensional accuracy are critical.

Our core pins are precision machined and heat treated to ensure reliable performance in demanding die casting environments, with dimensional tolerances controlled up to ±0.005 mm.

Product Description

Core pins are essential inserts used in die casting molds to create internal holes, slots, and functional internal geometries in metal components. Because these pins directly contact molten metal during the casting cycle, they must withstand extreme temperatures, pressure, and mechanical wear.

Our TiN coated H13 core pins combine the toughness and thermal stability of H13 steel with the superior surface hardness of a TiN coating. This combination enhances resistance to abrasion, corrosion, and thermal fatigue, while also reducing metal adhesion during the casting process.

Key features include:

• Manufactured from H13 hot-work tool steel

• TiN (Titanium Nitride) PVD coating for enhanced surface hardness

• Excellent resistance to wear and thermal fatigue

• Reduced friction and improved release performance

• Precision CNC machining and grinding

• Custom shapes and dimensions available

• Dimensional accuracy up to ±0.005 mm

These characteristics make TiN coated core pins suitable for long production cycles in high-pressure die casting molds.
