Preform Plastic Injection Molding Machine

Product Description

Generally, precision injection moulding machine has two indexes: the repeated error of product size and the repeated weight error of product.

The former is difficult to compare because of the size and thickness of the product, while the latter represents the comprehensive level of the injection machine manufacturer. The weight repetition error of ordinary injection moulding machine is about 1%, the better machine can reach O.8%, the precision machine is less than 0.5%, the ultra-precision machine is less than 0.3%, and the international highest level is less than O.15%.

Precision injection machines require the dimensional accuracy of products to be within 0.01-0.001 mm, and many precision injection moulding machines require high injection pressure and injection speed;

the clamping system is required to have sufficient rigidity and clamping precision; the pressure, flow rate, temperature, measurement and other parameters are required to be controlled accurately to the corresponding accuracy; multi-stage or stepless injection is used to ensure the moulding process;

The reproduction conditions and the repetition accuracy of the products are also discussed. The repetitive precision of injection moulding weight is stable, which includes three aspects: repetitive precision of plasticizing quantity, repetitive precision of injection quantity and temperature control performance of moulds.

There are many factors affecting these accuracy, the most important is the accuracy of the whole machine manufacturing and assembly, as well as the configuration of screw, electrical appliances, hydraulic and other parts of the injection machine, and the quality of the mold.

High Speed PET Preform Injection Molding Machine Energy Saving 0

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

 

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
