Excessive shear should be avoided.Die Heating,Coating.The die should be heated to 600 o F (315 o C),and care must be taken to heat the die uniformly.A magnetic thermometer,optical pyrometer,or a temple stick should be used to check
Following die casting of an aluminum alloy cylinder block with an insert liner having openings extending through the liner and block to the outside,the flash across the opening is removed by employing a mandrel in the liner with a passage through the mandrel registering with the liner opening,and inserting a male punch through the opening from the outside to shear the flash around the edge of the openingFinishing Schrock Metal ProductsShot blasting is a cleaning,deburring or de-flashing process of parts and materials using a metallic shot propelled at a high velocity.The process is typically used to remove rust,scale or any other dry surface contaminants from parts,and can also be used to produce uniform cosmetic surfaces on metal products.Fixed Rake Angle Conventional Hydraulic ShearingShearing,is a process which cuts stock without the formation of chips or the use of burning or melting.In strict technical terms,the process of shearing involves the use of straight cutting bladesorm of sheet metal or plates,however rods can also be sheared.Shearing-type operations include blanking,piercing,roll slitting,and
