Custom CNC Machining Stainless Steel 304 Barb Fitting

Product Introduction

Stainless steel barb fittings find extensive application in the fluid industry, with our custom-manufactured variants primarily utilized in ice cream machines. Crafted from food-grade stainless steel. Whether for conveying liquid ingredients, coolant lines, or sanitary tubing, our custom barb fittings integrate industry-standard fluid handling functionality with the specialized hygiene requirements of ice cream manufacturing equipment.

Material and process

As used in food industry, material is pretty important, it must reach to food grade stainless steel. 

There are many types of fitting, like elbow-1” spout.

The following pictures are the barb fittings 3D drawings which are sent from out customer.

The first one is consist of two components, which are welded to form an integrated structure: one end features a bent connector, while the other end is a nozzle. They all need to be CNC machined first. Then post-welding, both internal and external surfaces undergo precision polishing, with particular emphasis on the inner bore. This finishing ensures the internal flow path is smooth and free of burrs, minimizing fluid resistance and optimizing flow efficiency. The polished inner surface also reduces material deposition and facilitates easy cleaning, making it suitable for applications requiring high-flow performance or sanitary conditions.  Below is the inner sideview of the barb fitting:

Below is the comparison of the surface before and after polishing.

The manufacturing processes for other shapes follow a similar workflow, primarily comprising CNC machining, bending, welding, polishing, and other operations.  Some vertical nozzle with ferrule need to be welded the ferrule.
