extrusion die flat sheet die
Mold material is generally made of hot die steel. Extrusion die with 4Cr5MoV1Si, 5CrMnMo, 5CrNiMo and other materials. Extrusion speed generally by the extrusion ratio, die-hole-type and flat-mode, combined mode and other circumstances into account, the general experience more. Die in the continuous use of the process, the die hole is changing, the extrusion speed is also changing, so that the extrusion speed can not give a certain value. Die heating temperature is generally 450-480 ° c, in extrusion die flat sheet die extrusion process, the resulting friction heat, die welding room temperature to reach 550 ° c or more, this temperature can only be based on profile discharge temperature To calculate. Casting rod heating temperature process is generally 460-530 ° c, the temperature can be adjusted according to the degree of extrusion die flat sheet die.
