Make efforts perseverely, Achieve new breakthroughs in technology

Since the ratio of length and diameter is 16 times, Sijin intelligent has always insisted on technological innovation, continuously improved the equipment stroke, accuracy and lubrication system, and continuously simulated and trial the die case structure by using CPM simulation optimization software. The double stress sleeve structure is to eliminate the internal stress and strain, so as to ensure the fundamental guarantee of metal fluidity; the forming effect is more perfect by further controlling the hardness of raw material heat treatment.

Recently, Sijin has successfully trial produced 192mm long hollow parts, which is increased by 12mm on the basis of previous length 180mm. This means that Sijin intelligent has made another step towards the goal of 20 times for the ratio of length and diameter.
