Top 7 Tips For Design SHEET-METAL Tool


Being light, non-corrosive, favorable and strong, sheet metal finds a myriad of applications in almost every industry.

The design of sheet metal in this form is important and there is a strong backbone for a good quality product.

Being a sheet metal designer, it is important to make sure that while developing a sheet metal product, there is a set of goals and design strategies set out to ensure that the product is cost-effective as well as possible for Manufacturing.

Sheet metal

Just before defining functions, assemblies, mechanical properties, and manufacturing properties, the Designer should clearly specify each of these aspects in the Design Cycle.

While defining a set of guidelines for sheet metal design, depending on the application and manufacturing capabilities, there are some standard designs and manufacturing practices or Tips, which are established with deeper analysis of results and changes in industrial requirements.


The design of sheet metal in this form is important and there is a strong backbone for a good quality product.

Testing is used to visualize the K-factor in the bending area.

The bending process usually produces more stretch than the interior on the outer surface of the sheet metal.

This effect results in the formation of the cleavage if the sheet metal is bent beyond a particular point.

This point is called the minimum turning radius, and when a sheet metal designer develops design ideas, then this minimum turn radius should be kept in mind.

For design cases where the need to increase the minimum turn radius, the sheet metal must undergo procedures like polishing or grounding.

2. Hole size

In a sheet metal stock, it is important to specify the size of the hole, the location and its alignment.

It is always better to specify the size of the hole with a slightly thicker thickness.

Loading a high punch less than a hole diameter stock thickness, now burns in the hole and excessive thunder.

This also leads to dull pulling during the punch return, ultimately affecting the lives of both punch and stock.

The distance between the hole also matters and the empty thickness should be at least twice, if not more.

The distance between the hole ensures the strength of the stock and also avoids the hole during the bending process.

3. Bends, Pearls and Flanges

Especially in such cases where many sellers are involved, it is very common to get sheet metal part models with a normal modeling mistake related to bending and fillet.

A formed part is different from what it actually looks like.

As an engineer who creates a virtual sheet metal part, it is also important to understand the importance of bending relief to avoid metal tearing.

In addition, features like beads and flanges are for a specific purpose.

They reduce the spring back effect and add stiffness to the overall design of the part or product.

4. Room for Fabrication

According to the end use, sheet metal can often be used for many processes like welding, for which the grinding is required.

As such, it is important for the sheet metal designer to ensure that there is enough room for adjusting the construction option.

5. Minimum flange width

flange width

Flanges help in making sheet metal part quickly and easily.

To define flange, a sheet metal designer should use a standard rule which states that the flange width should not be less than four times the thickness of the sheet metal stock.

The low flange tool will cause the impression of sheet metal surface leaving.

6. Welding

Sheet Metal Designer often includes provision for brackets in design, in fact without looking for other possible options.

Welding should be adopted only when it is an absolute necessity, otherwise, in most cases, fasteners can help you to achieve the same design goals efficiently with minimal cost and simple design.

7. Edge Bending

Edge bending is used in nearly every sheet metal product design to give strength to the edges and the design is kept safe for the use of final customers.

However, ineffective bends can also cause unwanted complications.

To avoid any issues during the bending, there is a need for less than 90 degree angle provisions to reduce the cost and usage of complex equipment to bend.
