Depending on the material and your tool set-up, you can hem sheet metal up to 4mm thick. Check out our product specifications or contact WILA for advice. Align the hem along the sheet metal material. Specifications: Flattened - When checked, places the hem flush against the sheet metal material, using the Sheet metal model's Minimal gap for the space between hem and sheet metal.. Inner radius - When Flattened is unchecked, you can specify measurement of the inner radius of the hem. Column 1: S = Sheet metal thickness; Column 2: A = flattening height; Column 3: Necessary force per metre to flatten sheet metal with 450N/mm 2 tensile strength (mild steel), 1 T = 9.8 KN; Column 4: flatten sheet metal with 700N/mm 2 tensile strength (stainless steel); There are four primary hemming bending solutions designed to accommodate various bending . Align the hem along the sheet metal material. Specifications: Flattened - When checked, places the hem flush against the sheet metal material, using the Sheet metal model's Minimal gap for the space between hem and sheet metal.. Inner radius - When Flattened is unchecked, you can specify measurement of the inner radius of the hem.

4 Types of Sheet Metal Hems. Sheet metal hems have four main types. Each type is used for a particular purpose. In this section, we will discuss open, closed, roll and teardrop hems, their characteristics and uses in different industries. Open Hem. It is made by bending the metal sheet’s edge back onto itself without fully closing it.The hem tool adds a hem to your sheet metal part at a selected edge. Here are some additional items to note about the hem tool: The selected edge must be linear. Mitered corners are automatically added to intersecting hems. Contents. Hem .The hem tool adds a hem to your sheet metal part at a selected edge. Here are some additional items to note about the hem tool: The selected edge must be linear. Mitered corners are automatically added to intersecting hems. Contents. Hem .hemming process A closed hem A seam. Hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. Hemming is the process in which the edge is rolled flush to itself, while a seam joins the edges of two materials. [1]Hems are commonly used to reinforce an edge, hide burrs and rough edges, and improve appearance.
Hems can be useful as a way to stiffen a sheet metal panel. Hems have drawbacks, however. With plated steel parts, the interior of the hem can be very difficult to cover for corrosion control.
To model hems in sheet metal, I'm: - making two successive flanges - extruding away the intervening flat section - joining the bodies to make a 180 degree (e.g.) bend. Seems to work but wondering if there's a better .

Welcome to Kreatorzone! On this sheet metal design series you will find the recommended Common sheet metal design guidelines in Hem Feature Guidelines or Hem. Roll the hem over the edge, using a specific radius. Specifications: Inner radius - The measurement of the inner radius of the hem.. Angle - The angle of the roll, determining how far the roll extends towards the sheet metal wall.. The first image shows an angle of 270 degrees and the second image has an angle of 200 degrees
Another common type of sheet metal joint is the standing seam, which requires the forming of both edges. Standing seam joint. Firstly, bend the edge of the first piece at a 90-degree angle into a flange. Similarly, bend the edge of the second piece at a 90-degree angle, but with an additional hem formed over it. At this point, the hem will fit .
The Hem feature allows you to create one or more hems on existing sheet metal parts. Click the Hem feature tool on the Part Studio toolbar. Select the edges or side faces along which to create hems.

Types of Sheet Metal Hems. The flange is not always at 180 degrees, touching the sheet metal itself. It can have different geometries. Based on that different types of metal hem exist: Flat or Closed Hem. Closed hem, the most popular type, is also known as crushed hem. In this case, the returning flange is at 180 degrees to the sheet metal . Align the hem along the sheet metal material. Specifications: Flattened - When checked, places the hem flush against the sheet metal material, using the Sheet metal model's Minimal gap for the space between hem and sheet metal.. Inner radius - When Flattened is unchecked, you can specify measurement of the inner radius of the hem. Align the hem along the sheet metal material.

Inner radius - When Flattened is unchecked, you can specify measurement of the inner radius of the hem.
The open hem type allows you to fold the edge of the sheet metal to a 180-degree angle while leaving some space between the hem part and the primary sheet metal area. You can use the open hem space for various purposes, such as to ease the assembly process. Please note that the space between the hem part and the sheet metal area must not be too . Roll the hem over the edge, using a specific radius. Specifications: Inner radius - The measurement of the inner radius of the hem..
