TiN Coated H13 Sprue Bushings for Die Casting Molds
Product Overview
TiN Coated H13 Sprue Bushings are critical die casting mold components used to guide molten metal from the injection system into the mold cavity. Installed at the mold entrance, the sprue bushing ensures smooth and controlled metal flow while protecting the mold structure from wear and thermal damage.
Manufactured from H13 hot-work tool steel and enhanced with a Titanium Nitride (TiN) coating, these sprue bushings provide superior resistance to heat, erosion, and metal adhesion. The TiN coating improves surface hardness and reduces friction, helping maintain stable metal flow during high-pressure die casting operations.
These components are widely used in aluminum, zinc, and magnesium die casting molds, ensuring reliable gating performance and extended mold service life.
Product Description
A sprue bushing is a precision mold insert positioned at the entrance of a die casting mold. It serves as the interface between the injection nozzle and the mold runner system, directing molten metal into the mold while maintaining proper alignment and sealing.
Because the sprue area experiences extremely high temperatures, pressure, and metal flow velocity, the component must have excellent thermal resistance and wear durability.
Our TiN coated H13 sprue bushings combine the toughness of H13 tool steel with the enhanced surface performance of TiN coating technology. This improves resistance to abrasion, erosion from molten metal, and sticking during casting cycles.
Key Features
  • Manufactured from H13 hot-work tool steel
  • TiN (Titanium Nitride) PVD coating for enhanced surface hardness
  • Excellent resistance to thermal fatigue and erosion
  • Reduced friction and improved molten metal flow
  • Precision CNC machining and grinding
  • Suitable for long-cycle high-pressure die casting molds
  • Dimensional tolerance up to ± 0.005 mm
  • Custom sizes and geometries available
These sprue bushings help maintain consistent gating performance and improve mold durability in demanding production environments.
Applications
TiN coated H13 sprue bushings are used in die casting mold gating systems.
Aluminum Die Casting Molds
Provide stable molten aluminum flow from the injection system into the mold runner.
Zinc Die Casting Molds
Support precise and smooth metal feeding for zinc die casting molds.
Magnesium Die Casting Molds
Suitable for magnesium alloy molds requiring excellent heat resistance.
High-Pressure Die Casting Systems
Essential components in HPDC molds that guide molten metal into the cavity.
Mold Gating System Components
Installed at the mold entrance to protect the runner system and improve metal flow efficiency.

Frequently Asked Questions
What is the function of a sprue bushing in a die casting mold?
A sprue bushing guides molten metal from the injection nozzle into the mold runner system while maintaining alignment and sealing.
Why is TiN coating used on sprue bushings?
TiN coating improves surface hardness, reduces friction, and enhances resistance to molten metal erosion.
Why is H13 steel suitable for die casting mold components?
H13 tool steel provides excellent heat resistance, toughness, and thermal fatigue resistance, making it ideal for high-temperature die casting processes.
Can sprue bushings be customized?
Yes. Sprue bushings can be manufactured according to custom mold designs, drawings, and dimensional requirements.
What tolerance can be achieved?
Our machining capability allows dimensional tolerances up to ± 0.005 mm for die casting mold components.
