At the heart of Helander’s hydroforming services is our cutting edge 20″ hydroforming press. Sheet hydroforming is an ideal process for manufacturing parts with complex or asymmetrical geometries that would require multiple punch cycles in a matched die stamping process. By replacing one of the rigid dies with highly pressurized hydraulic fluid contained in a […]
At Helander, our powerful 80″ diameter spinning lathe provides a bridge between modern technology and one of the oldest metalworking crafts. By combining advanced CNC controls with high speed production and low tooling costs, it gives us the ability to provide a competitive alternative to the deep draw stamping process.
If you are in the ultra-competitive manufacturing world, you are always looking for an advantage. This is especially true when it comes to die molding specialty products like magnetic rotary pumps.
When considering the numerous options available for working with metal, many companies choose the beneficial and cost effective process hydroforming. Originally developed around 1950, hydroforming is ideal for shaping many types of ductile metals, including brass, aluminum, stainless and low alloy steels. It holds a number of benefits when compared to similar work processes, especially […]
Metal Spinning (or spin forming) is a process where a tube or a disc of metal is rotated at high speed and transformed into an axially symmetrical object. Metal spinning is usually performed on a vertical or horizontal lathe using CNC controls or hand processing. So, by its very nature, metal spinning is an example […]
The American Society of Mechanical Engineers (ASME) first published the Boiler & Pressure Code (BPVC) in 1915 in response to the need for safety measures in the production and use of boilers and pressure vessels. In the early 1900s, boilers and pressure vessels – closed containers designed to hold gases or liquids at a pressure […]
Metal Spinning has a long history that spans back to ancient Egypt and has progressed through the years to today’s more advanced methods of forming metal via spinning it. Today, the modern metal spinning process takes place on rigid lathes that incorporate high velocity spindles that shape the metal. These spindles are operated either manually […]
Metal Spinning is a process by which a disc or tube of ductile metal is rotated on a spindle and formed into an axially symmetric part. Through the use of heavy forces and high speeds, the metal will deform and “flow” to form the desired shape around a mandrel, a kind of mold that is […]
