1. HAIJIANG for injection molding machine features:

→ bigger space between tie-bars

→ central-clamping structure

→ famous components

→ energy saving with servo motor

→ low noise, fast respons

→ high precision, Stable and super long life

T-Slot Platen

abundant Spare Parts

→ better price

Clamping Unit:

1.) Optimized Platen Design with high rigidity and enlarged space between tie bars

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

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, HJS 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

About the PLC Control for  Injection Molding Machine

1.PLC control,the oil motor preplastification,full hydraulic pressure drive ,automatic cycle.

2.High plasticizing capacity,the temperature can be primary automatically controlled.

3.Adopt the digital pulse measurement,when using ,select injection quantity according to the mold requirements of each stage.

4.Adopt the single cylinder quality.the board scissor mol merged mechanism.

5.It has a second pressure injection.

6.The disc inversion is smooth,it is easy to adjust the speed.

7.This machine adopts water cooling method to improve the cooling rate,to ensure product quality.
