Extruding Sheet Metal

Hillman 12 in x 24 in cold rolled steel expanded sheet metal.

Extruding sheet metal. Extruding metal is one of the most extreme pressure applications in press working and generates lot of friction and heat. Relief height is generally kept greater than two times of sheet thickness plus bend radius. We are also renowned for customer satisfaction. The punch should be polished linearly to a mirrorlike surface finish.

We have the largest furnaces in the region capable of heat treating aluminum products up to 35 long. Bend relief in sheet metal bend bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner. 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. 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.

Extrude hole size position guidelines. The extrusion punch should be made of highly wear resistant tool steel powdered metal pm preferably or solid carbide material. Relieve the punch after extruding the straight section to allow for lubricant to settle into the negative portion of the punch. 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. If an extruded hole is too close to the part edge it can lead to deformation or tearing of the 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.
