Air Ducts

Ritus has considerable experience developing engineered solutions for air ducts for automobiles, commercial trucks and agriculture equipment.  Air ducts have specific features which can make molding challenging. Ritus works to understand how each part must perform in its environment so it will withstand repetitive use, chemical exposure and harsh conditions.

Construction is critical. Air ducts require thicker walls and may include ribbing to prevent collapse from the forces of vacuum suction. The addition of bellows or spectrum of curvature sizing across the part further complicates its design. OEMs should only trust an experienced manufacturer who understands the nuances required to create a tool and molding process that successfully unloads the part from the mechanism without compromising the product’s integrity.

Material expertise. No matter the production volume, from hundreds of pieces to a hundred-thousand, Ritus will recommend the best compound recipe for efficient vulcanization while meeting the demands of your project. Compound selection for an air duct varies depending on its application in the environment. Common materials include PVC nitrile, low-swell EPDM, neoprene, NBR, epichlorohydrin (ECO), and Vamac®. Hardness ranges between 60A to 85A.

Reliable performance. Quality testing is performed throughout the development process but can also be conducted inline during the course of molding. Our attention to detail and knowledge of material components makes us a trusted resource among leading automotive manufacturers. A notable example is our work with air ducts for use with small engine turbochargers to improve MPG ratings. Ritus successfully engineered a component to withstand heat and chemical corrosion.
