How Is Deep Draw Hydroforming Impacting You?

How Is Deep Draw Hydroforming Impacting You?

When you think about hydroforming, you will probably only think about the automotive industry. However, deep draw hydroforming will continue to be a dependable and authentic manufacturing process. Those who are using hydroformed parts, regardless of the industry they are in and how they are using it, will find that it can bring a variety of advantages and benefits to any situation.

Benefits of Sheet Metal Hydroforming

Benefits of Sheet Metal Hydroforming

Sheet Metal Hydroforming is similar to the conventional deep-drawing technique, but has significant advantages for the formed part and keeps the tooling costs and production costs low.

Below is the list of t benefits of sheet metal hydroforming, as opposed to the conventional deep-drawing technique.

  • Inexpensive:
    Hydroforming tooling can cost less than half the price of standard press tooling. Tooling generally required is a male die and a draw ring.  The rubber diaphragm typically acts as a universal female die in the sheet metal hydroform machine.
  • Functional:
    Irregularly contoured shapes are easily formed using hydroforming, it also makes it easy to form irregular shapes and contours because matching dies are not generally needed.
  • No Need to Waste Time Thinning Material Out:
    No need to waste time stretching. Hydroforming flows the metal rather than stretching it as a result you will have less wall thinning.
  • Less Work:
    Usually parts require multiple operations with a typical press, with hydroforming most of the operations can be condensed into one operation.
  • Save Money:
    Since almost all punches and draw rings are made of inexpensive cast iron, hardened tool steels are therefore not often needed. These type of tools carry a longer life span. Sheet metal hydroforming offers a wrapping action of diaphragm which does not cause scuff marks, shock, and stretch lines.
  • Quick Set Up:
    Tools are able to be mounted easily and quickly they are also self-centering and self aligning. Set-up times are much quicker and  very efficient.
  • Durability of Materials:
    Almost  all sheet metals can be hydroformed such as stainless steel, carbon steel, aluminum, copper, brass, precious metals, high strength alloys. The material’s thickness varies within the restrictions of the machine. Usually tool modifications are not required.

As you can see sheet hydroforming as its many benefits. If you would like more information please contact us with any question you may have.

Hydroforming Advantages for Automotive

Hydroforming Advantages for Automotive

Hydroforming metal is one of the most cost effective ways of creating asymmetrical parts for the automotive industry. Many parts used on cars today have irregular shapes making traditional methods of manufacturing more cumbersome and expensive. The strength and weight of hydroformed parts also lends to better produced products which are easier to work while maintaining an overall better structural integrity. Here are some other hydroforming advantages that make it one of the best choices for fabricating parts for the automotive industry:

  • Reduced tooling costs: When manufacturing parts the traditional way, jigs and other forms must be manufactured before the process of fabrication begins. If a company only needs a small quantity of the manufactured parts, the increase in cost for tooling greatly affects the bottom line.
  • Increased quality and precision: Hydroforming uses a technique which employs a press, pressurized fluid, and a punch. This process is not only quicker than traditional types of fabrication, it also ensures greater accuracy because their are less steps in the process of hydroforming than traditional manufacturing.
  • Deep-drawing with less stretch: Hydroforming uses less friction in the manufacturing process. Deep draws can be performed with less material stretch. This means the product will have a better integrity as well as less blemishing; in turn requiring less finishing work.
  • The versatility of hydroforming: Steel, copper, brass, aluminum, alloys, etc can be manufactured into parts using the hydroform process. When dealing with these types of materials, many additional efforts must be put into place with traditional fabrication processes as to not damage or weaken the material.

In the automotive industry material strength is essential for safety. The race industry has especially seen benefits from the light weight and structurally sound parts developed as a result of hydroforming. As hybrid vehicle become more and more popular, hydroforming has played an integral part in keeping cars efficient through bettering the manufacturing process.
