  2. Advantages of Hydroforming for Aerospace Applications

    Comments Off on Advantages of Hydroforming for Aerospace Applications

    Hydroforming is frequently and advantageously applied within the aerospace industry. The typically high complexity of aerospace components necessitates a fabrication technique that canaerospace-cap-edited-500x477 effectively produce the desired shapes and forms. Metal sheet hydroforming provides an economical manufacturing solution for parts with asymmetrical or complex geometries and irregular contours as the process requires fewer passes to produce the desired part than a comparable matched die stamping process.

    Comments Off on Metal Spinning Produces Tight Tolerance Components

    Depending on the specific form and structure of a component, there can be more than one metal fabricating process that can be used to meet the same end. Although different processes can achieve similar results, there may be greater benefits of one over another.

  5. Hand Spinning vs. CNC Spinning: Two Sides of the Coin

    Comments Off on Hand Spinning vs. CNC Spinning: Two Sides of the Coin

    describe the imageMetal 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 of a technology that has spanned a timeframe stretching from the days of hand-tooled craftwork to the modern computer era. How do the two techniques compare, and how do they complement one another? Good questions. Let’s take a look.

  6. Safety Under Pressure: Pressure Vessel Shape Matters

    Comments Off on Safety Under Pressure: Pressure Vessel Shape Matters

    pressure vesselThe 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 substantially different from the ambient pressure – were new innovations. These innovations promoted and advanced industrial activity in the U.S., specifically for companies that utilized machines for long-range transportation and heavy lifting.

  7. The Case for Metal Spinning and Metal Hydroforming

    Comments Off on The Case for Metal Spinning and Metal Hydroforming

    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 shaped to the interior geometry of the planned part. This process allows metal to deform evenly, without any wrinkling or warping, to create a smooth, even, and seamless surface. The processes’ heavy forces also realign and strengthen the grain structure, significantly increasing the tensile properties and fatigue resistance of the base material.
