Manufacturing of a Carbon Steel Venturi

In this project, we were contracted to manufacture a custom venturi for the filtration industry. The venturi shape produces a flow-dependent pressure drop, and features a temporary narrowing much like an hourglass figure to vary flow. It is utilized in a variety of filtration applications. Working from customer-supplied drawings, we incorporated multiple production processes to fabricate the part to the required specifications. Mild steel was cut and formed using laser cutting, spinning, hole piercing, and trimming techniques. In order to successfully execute the trimming and piercing of the hole to the precision required it was necessary to design a custom die. Additionally, the spin tooling required two separate pieces to complete.

The finished part measured 6″ in length by 5″ in diameter. The tightest tolerances of ± .015″ were achieved across the part’s diameter, and tolerance of ±.030″ on the length. The venturi was properly cleaned and left with a raw steel finish. We delivered with a short lead time, exceeding the quality expectations of the customer. This part is produced in annual volumes ranging from 1,000 to 5,000 units. Due to our consistent quality levels and dedication to accuracy and customer service we enjoy a long-standing production relationship with this customer.
