    Solutions for Custom Furniture Design

    The modern use of metals to construct furniture dates back to cast iron tables created in the early 19th century; contemporary designers seeking custom parts still frequently rely on metal for the construction of high quality furniture. Metal furniture not only remains durable and strong throughout its lifetime, but it also offers construction flexibility and deeply pleasing aesthetics.  While many metal forming processes exist for furniture construction, one of the best methods to create attractive and complex furniture projects is metal spinning.

    Durability in the Most Important Settings

    In the world of food processing, manufacturing the highest quality equipment is of paramount importance.  Not only does food need to be kept safe, but the equipment itself must be able to function smoothly even in the most difficult industrial conditions.

    Food processing equipment needs to endure high temperatures and resist corrosion in damp environments.  While there are a number of different materials and processes that are commonly used to manufacture this equipment, metal spinning using stainless steel allows for highly durable equipment that meets customers’ exact specifications.

  3. Metal Spinning Benefits and Applications

    Leave a Comment

    The metal spinning process consists of a tube or a disc of metal that is rotated at high-speed and machined into an axially symmetrical product using either a vertical or horizontal lathe. The advantage of spinning over other forming processes is its capacity to create seamless products from a single piece of material, with relatively low-cost tooling. Without seams, parts can withstand much higher internal and external pressures.

    You will typically find spun metal components in decorative and architectural parts. Spun metal parts are also featured in variety of machines, cookware, gas cylinders, and brass instruments, and can be made from a variety of materials. Let’s discuss the three most common materials for spinning.

  4. Difficulties in Metal Spinning Special Alloys

    Leave a Comment

    Too often in the metal fabrication industry, the phrase “we’re not set up for that” really means “we don’t want to do that.” When customers are met with either the unwillingness to manufacture their parts to print or the inexperience to know how to do so properly, the end project suffers greatly. Granted, it’s important for designs to be practical and feasible, but when a manufacturer says, “metal spinning with special alloys is just too difficult” it’s simply not true…for Helander anyway.

    Special alloys are in no way a hindrance to getting the custom parts you want, in the specifications you want them, and in the tightest of tolerances. In fact, one of the major advantages of creating parts via metal spinning is the ability to create quality, uniform, products out of traditional metal, alloys, and exotics alike. As long as a part is ductile it can be metal spun and even high-strength alloys are workable and machinable.

  6. 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. Custom Tank Heads: The Perfect Fit

    Leave a Comment

    Custom fabrication is a way of life at Helander. We’re all about making the exact pieces that our customers need, rather than a whole catalog of generic one-size-(never)-fits-all items. Our custom tank heads are a perfect example of this commitment to all that is custom. A tank head is the cover that you see on everything from milk and gas trucks to small water filtration vessels. It’s what keeps the liquid in the tank; the last line of defense, if you will. With such a ubiquitous product, there are lots of companies out there who make tank heads. You can buy them off the shelf by the truckful, but there is a major difference between our tank heads and theirs.
