Steel vs. Aluminum
Steel and aluminum are two popular metals for producing consumer and commercial metal goods. While both metals can have a shiny, silver appearance, have good forming characteristics, and can resist common forms of damage, the two metals offer very different characteristics and are used in distinct applications.
The Hydroforming Process: How Does It Work?
Hydroforming (Sheet Hydroforming) is a specialized deep draw process that uses high-pressure rubber to shape and form metal workpieces. In sheet hydroforming, a metal sheet is placed over a die before highly pressurized water forces it down and makes it conform to the shape of the mold. In tube hydroforming, a preexisting tube is set […]
Complete Guide to Metal Spinning
Also known as spin forming, metal spinning is a process manufacturers use to craft axially symmetric metal parts without cutting the material. This process is efficient and highly versatile. At Helander, we have spent over 80 years providing superior quality metal spinning services to our customers in the aerospace, commercial, medical, and defense industries.

Metal Spun High-End Commercial Cookware Components
What Is Metal Spinning? Metal spinning, sometimes referred to as spin forming, is a machining technique that creates axially symmetrical parts from metal tubes or discs. This process works by rotating the metal workpiece, forming it to a mandrel. Once clamped to a vertical or horizontal lathe, the force and rotation will shape the workpiece […]
Manual Metal Polishing vs. Automatic Metal Polishing Services
Metal polishing is a finishing process that uses abrasive materials to improve the surface of precision metal components. Polishing enhances the functional and aesthetic quality of the metallic surface by removing surface imperfections (e.g., scratches and nicks), improving corrosion and oxidation resistance, and/or adding a coarse, satin, fine satin finish.
Tips for a Great Metal Spinning Design
Metal spinning transforms workpieces into axially symmetrical objects. This technique is a lower-cost metal forming option and enables unique shapes – such as parabolic nose shapes, hemispherical, and cones – to be created from singular pieces of metal, as opposed to forming seamed pieces that are structurally weaker. Here we will share some insights about […]
