|Benefits and Features
allow you to stand out in today's competitive environment.
improve the quality, efficiency and competitiveness.
make better decisions, create better cast, to achieve better profits.
High-speed data acquisition hardware
a.Precision sensor technology
b.件 High-speed data acquisition hardware
● Detect the magnetic field by the difference caused by the internal structure of the threaded rod.
● Up to 12mps
● Resolution to 0.3175mm
● The Max. Injection speed ≥8m/s.
● Convenient and fast automatic control, high flow control precision.
● PLC can realize intelligent automatic adjustment function.
● Setting data can be stored memories
Servo push rod is implemented by the servo motor to adjust the cartridge valve opening. With the continuous development of casting technology . Higher demands are proposed for die casting machine in the work of stability, reliability, security and accuracy. At present, the general die casting machine in the injection system, for fast and pressurization control valve, mainly with the following two kinds:
“Traditional handwheel adjustment cartridge valve"
Traditional handwheel adjustment cartridge valve. The cartridge valve cooperates with screw rod and handwheel, need manual adjustment, simple and reliable oil circuit, convenient electrical control and low cost.But not adapting to the trend of the automation development, as low accuracy adjustment, no setting data memory, the handwheel and indicator vulnerable to vibration damage, etc.
Electric proportional adjustment cartridge valve
Convenient and fast automatic control, high precision flow control, setting data easy storage. But with complicated control oil circuit, high cleanliness requirements of the oil, high cost, long delivery cycle, etc.
The application of servo push rod in the die casting machine
Muler company actively research and manufacture electric control valve with the development of the market, at present, electric control valve has been pushed into the market, Get the clients' universal welcome and affirmation.
● Max. injection speed 大于8m/s，average error ± 0.04m/s.
● achieve full open degree of flow control’ overcome the proportional valve with dead zone control section.
● can trouble-free work when the oil cleanness level NAS8, the low requirements for hydraulic oil cleanliness.
● with feedback device, can realize intelligent automatic adjustment function by PLC.
● simple,reliable and safety, setting data can save memory.
