Metal Spinning vs. Hydroforming

Metal spinning and hydroforming are two of the most utilized industrial processes in manufacturing a wide-range of products from satellite dishes, gas cylinders, lighting hardware,  to musical instruments, and more. Understanding each method and its benefits will help you decide which metal forming technique best suits your application.


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?

www.helandermetal.comwp-contentuploadshydroforming-irregular-parts-img-large-1Hydroforming (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 between two dies, and water pushes the interior of the tube to expand and conform to the new shape. Both processes allow for the seamless forming of new shapes and parts in common metal alloys without welds. Additionally, the hydroforming process is an excellent choice for developing complicated, irregularly-shaped parts or products. At Helander, we specialize in high-quality metal-forming and manufacturing services to create custom parts for a wide range of applications across different industries including Sheet Hydroforming and Metal Spinning.

Complete Guide to Metal Spinning

metal-spinningAlso 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.


Satellite Dishes in the Military & Defense and Aerospace Industry

At Helander Metal, we provide metal forming and other fabrication services to customers in the aerospace, defense, and military industries. Armed with over 85 years of experience, highly capable employees, and advanced equipment, we have what it takes to deliver high-quality precision metal parts and products that meet some of the tightest tolerances and timelines. That’s why customers in these critical industries know they can rely on us to produce components for their devices and systems, including satellites.

What Is Metal Spinning?

AdobeStock_309675261Metal 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 into a cone, tube, toroid, or other rounded shape. 


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 the metal spinning process to help you choose the right materials and other considerations for your next project.


All About Our Custom Tank Heads

At Helander, our metal spinning and sheet hydroforming processes produce a range of durable tank head imageand high-quality metal parts. Tank heads especially are a perfect fit for our metal forming processes. We produce our tank heads in a number of dimensions and shapes, depending on each client’s specific needs. This blog will discuss how Helander makes tank heads and the advantages of using custom-made options instead of choosing stock tank heads.
