Conformal Cooling Channels
Conformal cooling channels, also known as conformal water channels or conformal cooling circuits, are a new type of mold cooling water system based on 3D printing technology. These channels are designed to closely follow the shape of the molded product, allowing for a precise fit and optimal cooling. Unlike traditional cooling channels that are limited to circular cross-sections, conformal cooling channels can have any desired cross-sectional shape, offering enhanced cooling performance and improved overall mold efficiency.
Traditional Water Channel Design
• Straight-line cooling channels that are positioned far or further away from the mold cavity.
• Requires additional fittings for water channel assembly.
• Contains more dead zones with poor cooling/heating efficiency.
• Requires cutting and assembling multiple pieces, leading to cumulative errors and shorter mold lifespan.
Conformal Water Channel Design
• Water channels designed to conform to the mold cavity surface, ensuring uniform proximity.
• Avoids right angles for smooth flow and improved efficiency.
• Allows for varying cross-sectional shapes of the water channels as needed.
• Enables the design of multiple cooling circuits to enhance heat dissipation uniformity.
