Rotoforming

Rotoforming is a CNC controlled hot spinning process that utilizes a flowformed cylinder to create a bottle-shaped pressure vessel that has a thick neck and a thin side wall on the main body. The CNC process accurately controls the profile of the neck while delivering controlled wall thickness and repeatability.

PMF's rotoforming process includes simultaneous machining to ensure concentricity with the machining features of the neck and the outside diameter of the flowformed cylinder. The rotoforming process can be used on a variety of materials, including stainless steel, brass, and aluminum.
