Sheet Metal Slot Design

Consider material and finishing options along with design elements like bends reliefs holes and slots when developing sheet metal components before diving into the details of sheet metal fabrication recognize a basic fact of all sheet metal parts.

Sheet metal slot design.

Sheet metal materials are the most commonly used materials in the structural design of communication products. Center to center distance between two holes. In sheet metal fabrication parts are formed from metal sheets by punching cutting stamping and bending. Available in aluminum and carbon steel our slotted hole types also lend themselves to several industrial applications.

A 1 degree tolerance on all bend angles. In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm. When designing parts for laser cutting one should not make holes smaller than the thickness of the material. Minimum distance between hole slot edge to bend edge is recommended to avoid metal distortion deformation and fracturing.

The minimum distance from the inside surface of a bend to the edge of a slot is directly proportional to the length of the slot material thickness and radius of the bend. Consider these important design tips when creating holes and slots in sheet metal parts. Bends in sheet metal are manufactured using sheet metal brakes. They start out flat.

Recommended minimum distance between hole slot edge to bend in sheet metal design is three times the sheet thickness plus bend radius. More information on this tech tip available at. Be mindfull if you have tabs on adjacent bends when the part is bent wrong it may or may not fit in all of the slots anymore. Understanding the comprehensive performance of materials and the correct material selection have an important impact on product cost product performance product quality and processability.

Slots the minimum width of a slot is equal to the material thickness or 1 00 mm 0 04 inch whichever is greater. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. 3d cad files are created using a host of different cad packages and then converted into. These products bring a unique aesthetic to wall cladding sunshades furniture and other design applications.

Avoid large sheet metal parts with small bent flanges.
