Sheet Metal Enclosure Design and Layout Tips and Tricks

Everybody wants their home to have an aesthetic appeal and the ‘wow’ factor which amazes everyone. These days metal and iron furniture and show pieces are in fashion and give a creative yet pleasing look to your home. These metal designs can be both mass produced, which are cheaper and readily available or handmade which are exotic, a little costly and expressive. Handmade metal designs have recently earned popularity because they are customizable and are made according to your taste. This gives a unique look to your home. But these metal sheet enclosures could be a tricky part while designing or implementing. Here are some simple tricks to plan and execute a design perfectly.

  • Dimensions: Critical dimension is an important part of the design. It has to be highlighted. These critical dimensions have to be high tolerance, but making it excessive would ultimately add to the cost of the product.
  • Height to Thickness ratio: This aspect is also known as the Flange Dimensions. The flange length has to be compared to the Vee die opening and material thickness to make the ratio correct. For those of you who do not know about Flange length, it is simply the distance between the bend and edge of the part of the design. Making this ratio correct is important for not only the bending process, but also controlling slippage.

Adding the bending radius and thickness of the material should be same as one fourth of the flange length. If the flange length is not longer than half of the vee die opening, it could affect the bending process.

  • The Radius: Here we talk about the bend radius of the design. This is important to prevent fracturing problems and material flow problems. As a matter for standardization, it is beneficial to keep Bend radius equal for all. This save costs on changing the setups and increases efficiency. The material thickness has to be equal to the bend radius. In this regard the inside bend radius has to be taken into consideration rather than the exterior or outer one.
  • Controlling Distortions: An enclosure design could be quite tricky for many. If not done nicely there could be distortions while the bending is in process. This could result in the whole sheet going to waste. For this the bend radius (interior) should be twice (or sometimes more) than the thickness of the metal. This means that the holes should not be close to the bend.
  • Deductions: Knowing the limitations of the material becomes very important to know about how much the material can bend. This depends on different metals. A designer should always know about the limitations of different materials so they can know and select which material to use. The parameters which it is judged upon is the thickness and bend radius of the material.

A better sheet enclosure might not only increase the life of the design but makes it look natural and appealing to eyes.
