Powerjet Energy Saving PET Preform injection molding machinePET-350V2

Features:
Integrated Evaluation
A better cost performance is seen for the S6 series.


Outstanding Energy Saving
Comparing with the hydraulic machine, S5 series can save more 50% of the power. Comparing with full electrical machine, energy saving is more abviously seen during pressure hold & cooling stage.


Better Stability
With the adoption of servo control system, the injection pressure & speed 15 under close-roop controlled, and the stablity and repeatability can be achieved.


Faster Response Speed
S5 series only needs 0.05 seconds to achieve the Max. flow rate, which effectively shorten the cycle time and thus improves efficiency.

Clamping Unit

·Five pivots hyperbolic toggle clamping mechanism has characteristics with fast opening and closing , stable and energy saving through the optimized design.
·With Differential high speed mould locking function, it can effectively shorten the molding cycle time and improve the work efficiency of the machine. 
·The mould plate adopts the finite element technology on structure auxiliary analysis, that makes the mould plate structure more reasonable, strength and resistance to fatigue better, extending service life; 
·High rigidity antifraying tie bars plated with hard chromium has advantages of high precision, high strength, high strength and long life. 
·Reliable low pressure protection function greatly prolongs the service life of the mould. 
·The clamping and ejecting stroke of the mould are controlled by high precision electronic sensor, the setting precision can achieve + / - 0.1 mm. Low pressure protection and ejector stroke set get more directly and simply. 
·The protection devices of mechanical, hydraulic and electrical ensure that the operating personnel is safety, and fully embody enterprise culture with human-oriented. (Note: Size above BJ400 machine, the hydraulic safety protection device is the standard configuration.) 
·To control lubrication system automatically according to how many times to open and close the mould, the automatic quantitative lubrication system can guarantee the clamping machine more stable, reliable, and longer life. 
·Hydraulic motor with gear adjustable system, makes mold adjustment more reasonable and perfect. 
Injection Unit

·High efficient separation type screw, high mixing screw and all kinds of special screws, improve the applicable scope of the material and guarantee molten material uniform and measurement stability. 
·Duplex balanced injecting device provides higher injection pressure, makes the unit more simple and stable, lowers the failure rate. It is more convenient to maintain and save space meanwhile. 
·Machines above BJ288 with double injection shift cylinder accept the stress more reasonable and effectively prevent the nozzle deviation, avoid material leakage. 
Electric Controller

·High performance of switching power supply can normally work with operating voltage from 160v to 280v , which can be adapted for all kinds of bad power environment; 
·Using high pixel (800 x 480) large capacity TFT true color display, it makes the display content more rich, the process adjustment more intuitive , the operating more simple and the function more perfect. It also can simulate machine action. 
·High-speed CPU with increased capacity storage not only meets the requirements of the process control system, but also can use graphic to record complete injection process, make the injection process control to be more convenient. 
·Large capacity storage make monitoring, alarm, mould parameters store capacity multiplication, can store 200 sets of mould injection data, can record 200 constitutive monitoring data and 200 times alarm information. Mold data can choose copy or clear freely. At the same time, it still can use SD card to read and store the mould data, that is more conducive to mass production management. 
·Equipped with internet communication port, injection molding machine can be realized network management, can be real-time monitoring factory production status and the working condition of injection molding machine, to realize the factory automation production. 
·Perfect automatic monitoring and a large number of internal parameters, can assist you to adjust machine’s every movement to the best condition. 
·Six sections injection speed, pressure and three sections of holding pressure, speed control, can satisfy all sorts of complex products process conditions. 
·Three sections of the charging speed, pressure control, ensure the plasticizing more uniformity, faster and more stable measurement. 
·Rapid temperature control system, using FUZZY control mode, has the faster warming, high precision characteristics, temperature control accuracy reach to ±1 °C in static time. At the same time it provides high low temperature deviation alarm and thermocouple bolt check out. 
·Function to prevent cold material start-up. 
·Mold locking, injection and ejector stroke use high precision electronic sensor to control the position, the setting accuracy in +/- 0.1 mm. 
·Supported with ejector stay, thimble shock and multiple ejector function. the speed and pressure of thimble forward/backward can be divided into two stage control. 
·Forming number setted with automatic stop, which is more convenient for production management. 
·Defective products monitoring: when machine operates in automatic mode , the computer will be for each cycle injection monitoring, to judge product and machine normal or not. 
·Automatic Adjustment Mode : can direct input clamping pressure, the mold thickness will be adjusted by computer automatically, that makes the clamping force to be in accord with high clamping pressure. 
·Data setting lock prevents improper personnel change. 
Features of lubrication system

·Major friction parts are equipped with lubrication points. Central oil supply system is used for hinges. Electric lubricant pump controlled by computer sends automatically lubricating oil (grease) to lubrication points. Lubrication is simple and high efficient. 
·Intelligent volumetric centralized lubricating system, controlled by computer, sends quantitatively lubricating oil (grease) to wearing points, and guarantees that the key carrying surfaces are lubricated reliably. The repair is visual, convenient and fast. The service life of the machine is longer.
