3.Perfect after-service
FEATURES
- A variety of text can be switched.
- Manual, semi-automatic and fully automatic mode.
- Automatic movement monitoring with alarm and fault diagnosis.
- Function of slope setting can set the start and stop of movements, so as ensure the smooth movement
Â
CONTROL SYSTEM
All-digital control system uses dedicated controller, multiple CPU processing division,
a multi-functional automatic fault detection, alarm system, certificates 99 mold of
processing procedures, with remote control interface. System is of high stability and
responsiveness. System uses color LCD, man made interface for easy operation and
with a number of peripheral interfaces.
Â
HYDRAULIC SYSTEM
Advanced hydraulic system design, through proportional control of pressure, flow achieves rapid multi-level pressure, speed switching, the system configuration is reasonable, stable and reliable. The noise is less than 75 dB. The medium and large machine adopts a two-way cartridge inserted valve system to improve the system of flow and speed of response, and makes the whole machine reach the best performance.
SERVO SYSTEM
After receiving the pressure and flow instruction from computer controller, the servo driver will compare it with the actual pressure and flow feedback, and rectify the difference by controlling the rotating speed of the servo motor. In this way, the control of injection molding is not only acurate but also fast, and the repeatabillity of the products high as well.

Ferrotungsten is prepared from wolframite by carbon reduction in an electric furnace. Mainly used as alloying element additive for tungsten-containing alloy steel (such as high-speed steel). There are three varieties of ferrotungsten produced in my country, including W701, W702, and W65, and the tungsten content is about 65-70%. Due to its high melting point, it cannot flow out in a liquid state, so it is produced by agglomeration method or iron extraction method.
