Product Description
Injection Unit
|
High L/D ratio of plasticizing screw |
| A,B,C three selection for Screw and Barrel |
| Screw and Barrel adopts excellent metal material (38CrMoAL), nitrided. |
| Four stages adjustable for plasticization speed/pressure, and three stage adjustable holding pressure. |
| Temp. Controller type PID. |
| Adjustable back-pressure controls and melts decompression device. |
| Injection screw directly driven by a low speed high torque hydraulic motor. |
| Computer A62 adopts Linear potentiometer for mould platen and screw position controls, precision reach to ±0.1mm.. |
| Injection system adopts double balanceable cylinder. |
| Clamping Unit |
Optimize designed five fulcrums and double inclined toggles clamping unit has functions such as big force enlarge rate, high-speed placid movement and large mould-open distance. |
| Having hard chromed on the surface, the tie bars are corrosion-resistant and wear resistant. |
| Several speed and pressure adjustable stages for opening, closing mold. |
| A62 adopts the linear potentiometer to control position of opening & closing mould, the precision reach to ±0.1mm. |
Mechanical and hydraulic eject device with one time or multiple ejects function.
A63 adopts the linear potentiometer to control position of eject, the precision reach to ±0.1mm. |
| Automatic centralized lubrication system |
| With reliable mechanical, electrical safety device. |
| Control System |
16BIT CPU multi-function computer |
| Several types computer for your selection A60, A62, A63, S6000 etc. |
| Chinese/English language (selectable) toggle mode, input & output use photo-coupler to protect damage from outside interference. |
| Indicate operation status & alarm with statement, easy to trouble-shooting. |
| 50 sets mould data storage. |
| Close-loop PLD technology is used in temperature control with the advantage of high precision. |
| Record time of production, quantity automatically. |
| High efficiency hydraulic system are composed of world famous hydraulic components, pressure & flow proportional hydraulic system combined with solenoid valve and logic valve keeps the system under stability and low energy consumption. |
| When temperature too higher or too lower, the Computer will protect the longevity of Screw & barrel by controlling heating. |
