How does the injection machine set up the die segments and the pressure and speed of each segment? Seek advice.
The new technology is the use of branch switch reluctance servo motor, motor CNC pump speed control speed, motor CNC pump torque control pressure, through the touch screen input segment parameters, the implementation of numerical control.
Then enter the low voltage protection process.Low pressure process with 0 speed, 0 pressure for the best, special circumstances increased to less than 20%20bar. The distance is at the end of the starting point of the high voltage die.High voltage medium and low speed 40-60%, medium high voltage 60-100bar is appropriate. The starting position is the termination position of the die closing +3-5mm.Among them, the determination of the fast termination position and the low voltage termination position is particularly important.Speed and pressure focus on the smooth movement of the die without vibration. Special attention is paid to the setting method of low voltage protection.The above is personal experience, and I hope to help you.
Simple injection molding closed mold process is divided into start - Fast - low pressure - high pressure four processes,Among them, the starting speed should be low speed and low voltage (usually 30% or less 40bar), the distance is about 5-10mm, and then enter the fast closed die process.Medium speed (40%-60%) and medium pressure (30-50bar) should be used in fast closed die. The distance is longer, the distance begins at low voltage protection, and the position is not finished.
