Injection Molding and Assembly of Air Valves for the Shipping Industry

Molding of an Air Valve Assembly for the Shipping Industry

At KRC Custom Manufacturing, we provide quality plastic molding services for various applications. We were contracted by a customer in the shipping industry to manufacture an air valve assembly. This customer was unhappy with the quality of the products from their former supplier, and turned to us in 2003 due to our reputation for quality and customer service. We have been working together ever since.

Using our advanced equipment, we can manufacture over 1.4 million air valve assemblies per year for this customer. Manufacturing required the use of our Van Dorn 50 ton, Demag 60 ton injection molders, and our 8 station semi-automated rotary assembler. Our 60 ton Demag was used to run the bodies and blue handles, and the seals and plungers were run on our 50 ton Van Dorn. Our 8 station semi-automated rotary assembler was used to place and press the air valve assemblies together. Each part is made of distinct material; the bodies are made with LLDPE, the seals are made with Santoprene, and the red plungers and blue handles are made with HDPE.

For this injection molding project, we also assembled multiple parts including the body, seal, red plunger, and spring to offer as an assembled unit. This unit is used to fill and hold air in a dunnage bag, which fills empty space in a trailer, rail car, or container. Our customer was able to take advantage of our primary and secondary offerings, having the project molded and assembled in one location.

Quality assurance testing is completed through visual inspection and leak test sampling of the units. To learn how KRC Custom Manufacturing can supply you with our injection molding services, do not hesitate to contact us.
