The extrusion punch should be made of highly wear resistant tool steel powdered metal pm preferably or solid carbide material.
Extruding sheet metal.
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.
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.
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.
The length of the extruded part will vary dependant upon the amount of material in the work piece and the profile.

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.
Heat treatment we are a nadcap accredited heat treatment facility.
Relieve the punch after extruding the straight section to allow for lubricant to settle into the negative portion of the punch.
