Product Description

Plastic Mixed Double Color Injection Molding Machine
FEATURES
The injection molding of the hybrid two-color injection molding machine uses the thermophysical properties of plastic plasticity. The plastic raw materials of different colors enter two or more barrels through the funnel, and the heating coil on the barrel heats the internal plastic into a molten state. There is a rotating screw in the barrel. Under the driving action of the screw, the material in the molten state is transported forward along the screw groove and compacted. The material slowly begins to plasticize, melt and homogenize under the dual action of the shear force of the screw and external heating. When the screw rotates, the molten material is pushed to the head of the screw under the action of shearing force and the frictional force of the screw groove. At the same time, under the reaction of the material, the screw retreats and gradually forms at the head of the screw. The space for storing materials can complete the whole plasticizing process. Then, under the thrust of two or more injection cylinder pistons, two or more screws inject the material in the storage chamber into the mold cavity of the mold in the form of high speed and high pressure. After the molten material in the mold is kept under pressure, cooled and fixed and
plasticized, under the action of the mold clamping mechanism, the mold is opened, and the ejector device ejects the shaped product inside, which completes the entire injection molding process. In this process, it is all completed automatically, and the mixed color plastic products of the mixed two-color injection molding machine are formed.

2. Euromap-based Platen Layout with both T-slot & tap holes, locating design in moving platen to better suit various molds 
3. New ejection system design with longer ejection stroke, bigger space and better rigidity 
4. Hydraulic drivien gear-type mold height adjustion mechanism 
5. Relocation of mechanical safety interlock for easier operation 
6. linkage structure for front connecting rod increases connectingrod's strength greatly, as well as the whole clamping unit's rigidity & accuracy

Injection Unit:
1. High Quality Linear Motion Guide ensure the smooth & accuracy of injection process 
2. High Speed & Pressure injection structure can improve the injection speed 
3. Twin nozzle cylinder ensures more even & stable structure 
4. Specilized screw barrel design for various appliance
 



Hydraulic System:
1. The double proportional compound valve control system pressure & flow, highly sensitive & stable 
2. Imported high quality Pump, low in noise, long in lifespan & stable in performance 
3. World-famous servo hydraulic system optional, better performance in lower noise & energy saving 
4. The precise feedback control of servo system to the pressure & flow, with higher sensitivity & more accurate repeatability precision 
5. High performance hydraulic valve, less failure, fast switch, convenient maintenance 
6. Low pressure mold protect system, which is more suitable for the precise mould 
7. Greese & lubrication oil in dependent lubrication system can lubricate everywhere in the best situation


 
Electrical System:
1. Control by double CPU, the system HMI use X86 300MHz technical grade display. The system employees a RISC 140MHz microprofessor, with high speed, noise-immunity, fan-less and lower power consumption, independent control structure improve the stablity of control 
2. 8.4" display screen with resolution 800*600, user friendly screen & optional choose of language 
3. Equiped with USB(2.0) port & ethernet(100-base T) ports 
4. 32 Points input & output, entendable and trouble spot can be replaced easily 
5. Linder transducer's resolution is 1/65535, more precise in control 
6. 120 technological parameters access can be stored & uploaded with an ordinary USB drives 
7. Injection End and temperature tracking is curve display, dynamic recorder parameter is modified, dynamic warningis exhibited, all these make the operation more convenient.


 
Servo Controller Part:
1. High Precise Control The servo system can control the machine's pressure, speed & location precisely, make sure that the error of  accurate repeatability precision for the shot measurement is <0.3% 
2. High sensitive response Because the motor vector is matched with the controller accurately, it only takes 0.5sec. inputing the number from 0 to max. Compared with other traditional hydraulic injection molding machine, HJ series is more faster in speed with shorter cycle time and high efficient in production 
3. Low noise Compared with traditional fixed pump & variable pump system, the noise is 1/10 lower under normal circumstance, more suitable for sealed dustless workshop 
4. Energy Saving Overall efficiency is 10% more & driving capacity is 18% more than common machine. This series can save 40-80% energy, and achieve first-class energy efficency 
5. Water cooling saving The system condition prevent high pressure uploading without any power output, leads to the water cooling saving
