Extruding Sheet Metal

Extruding metal is one of the most extreme pressure applications in press working and generates lot of friction and heat.

Extruding sheet metal.

Item 168753 model 11786. Extrusions we are a raw material supplier of aluminum extrusions to the aircraft industry we perform large and small production runs of custom extrusions up to 10 diameter as well as stretch forming of large and small aluminum extrusions. Many companies have found that aluminum extrusion is the way to go and have decided to move beyond using sheet metal to create their machined products. Extrude hole size position guidelines.

We are also renowned for customer satisfaction. Hillman 12 in x 24 in cold rolled steel expanded sheet metal. Steel expanded metal is a sheet product that has been slit and stretched to a wide array of diamond shaped openings steel expanded metal offers savings in weight and metal free passage of light liquid sound and air while providing a decorative or ornamental effect. The extrusion punch should be made of highly wear resistant tool steel powdered metal pm preferably or solid carbide material.

The length of the extruded part will vary dependant upon the amount of material in the work piece and the profile. Heat treatment we are a nadcap accredited heat treatment facility. Metal extrusionis a metal forming process in which a work piece of a certain length and cross section is forced to flow through a die of a smaller cross sectional area thus forming the work to the new cross section. We have the largest furnaces in the region capable of heat treating aluminum products up to 35 long.

If an extruded hole is too close to the part edge it can lead to deformation or tearing of the metal. The punch should be polished linearly to a mirrorlike surface finish. Relief height is generally kept greater than two times of sheet thickness plus bend radius.
