Jet Cooling Pins

Jet Cooling Pins

Overview

Jet cooling pins are precision-engineered core pins (or insert pins) that integrate high-pressure cooling channels. These pins deliver rapid, localized thermal regulation directly at hot zones—such as small-diameter core pin tips—during the casting or injection molding process. This jet cooling technique significantly enhances product quality, accelerates cycle times, and minimizes typical thermal-related defects.

Jet Cooling Pins

Key Features

  • High-Pressure Cooling Channels
    These pins feature internal jet cooling passages—often as narrow as 2 mm, and drilled ideally up to 10 mm from the tip. The thin-walled design (often < 3 mm) ensures efficient heat extraction. 

  • Superior Thermal Stress Control
    Jet cooling helps manage heat at the critical core-pin interfaces, reducing issues like soldering, shrinkage porosity, and erosion—thus enhancing component lifespan. 

  • Enhanced Casting Quality & Consistency
    By eliminating hotspots and improving solidification control, jet cooling helps reduce dimension variations, defects, and the need for release agents, resulting in smoother surfaces and more reliable parts. 

  • Faster Cycle Times & Production Efficiency
    These cooling pins enable quicker part solidification and ejection, improving overall productivity and reducing scrap rates. 

  • Durable, Long-Life Core Pins
    When paired with advanced materials and surface treatments (like nitriding or high-grade tool steel), jet cooling dramatically extends the core pins’ service life and mitigates thermal fatigue. 

  • Leak Detection & Safe Cycling
    Advanced systems include air purging post-cooling and leak detection mechanisms, ensuring safe operation and avoiding residual moisture or failures.
