Radhe Industries is a leading manufacturer and supplier of high-quality Brass Core Box Air Vents designed for efficient air and gas release during core-making and foundry casting operations. These precision-engineered brass vents help eliminate trapped air, improve mold filling, and reduce casting defects, resulting in superior casting quality and consistent production performance.
Manufactured from premium-grade brass, our core box air vents offer excellent durability, corrosion resistance, and dimensional accuracy. They are widely used in foundries, shell molding, core boxes, and various casting applications where proper venting is essential for achieving defect-free castings.
Our Brass Core Box Air Vents are available in slotted type designs that provide effective air escape while preventing sand leakage during the molding process.
Our brass foundry air vents are engineered to survive aggressive sand blasting and high-volume molding production cycles:
Optimal Air Evacuation Efficiency: Micro-machined exhaust slots are geometrically optimized to maximize air ventilation volume while completely retaining fine-grain silica sand.
Heavy-Duty Brass Construction: Highly resilient against abrasive sand wear, chemical binders, and thermal shifts, preventing premature deformation or slot closing.
Perfect Outer Diameter Tolerance: High-precision CNC turning ensures strict concentricity and outer diameter control for a tight, wobble-free press-fit inside your core box pockets.
Zero-Burr Finish: Smooth, polished top faces and clean internal slots prevent core sand from sticking, allowing for rapid core stripping and reduced maintenance downtime.
Self-Cleaning Structural Geometry: Slanted or tapered slot internal frameworks help expel micro-dust and binder residues during the air purge stroke.

We offer comprehensive dimensional and style variations to match diverse cold-box, hot-box, and shell-molding core production requirements:
Standard Slotted Brass Vents: Featuring straight, parallel, precision-cut slots. The industry choice for high durability and ease of cleaning in heavy-duty automated core shooters.
Ultra-Fine Slot Profiles: Custom micro-slots engineered for foundries utilizing extra-fine specialty or synthetic molding sands where standard vents might allow leakage.
Comprehensive Sizing Fleet: Our massive range of stock diameters from 4 mm up to 25 mm ensures tool-makers can find the perfect size to fit intricate contours as well as wide flat sections of the core pattern.
Custom Depth Options: Beyond our standard 7 mm and 8 mm lengths, we can custom-turn step-shouldered or extra-deep vent bodies to integrate seamlessly into complex or thin-walled tool plates.
At Radhe Industries, we manufacture Brass Core Box Air Vents with strict quality control and precision machining standards. Our products are trusted by foundries and industrial manufacturers for their reliable performance, durability, and consistent quality.
We also offer custom sizes and specifications as per customer drawings and requirements.
Does your advanced automated core-shooting machine require non-standard slot angles, an extra-wide shoulder lip, or specialized metric lengths outside of our standard 7 mm & 8 mm lineup? Radhe Industries excels in contract blueprint manufacturing. Securely submit your 2D engineering sheets or 3D CAD files straight to our technical desk. Our pattern-tooling specialists will review your requirements and manufacture custom brass core vents perfectly tailored to your foundry’s sand profiles.
