380T - plastic injection molding machine
Haishi Injection molding machine HS-398
● Excellent molding stability
The servo driving system has its pressure and flow under closed loop control; and compared with traditional injection molders, its molding repetition precision is improved substantially
● Constant oil temperature
The servo motor output hydraulic oil proportionately to prevent excessive heat. It can achieve substantial water saving even without cooling.
● Rapid response
The servo driver features rapid response whose rapid starting time is improved by 50% compared with traditional injection.
● Substantial energy saving
Under the same conditions, it can save 20%-80% energy compared with traditional constant delivery pump injection molders.
● High performance environmental protection
The complete machine features low operating noise, and even quieter during low-speed operation
Haishi creates independently the box type high rigidity mold structure for the clamping part; the clamping support guide rail adopts the high rigidity design to reduce the deformation effectively; the toggle structure optimized and designed with computer achieves exceptionally stable and rapid clamping; and the enlarged mold thickness, the gear mold regulation unit and the internally installed mechanical safety lock as well as the 180-degree rotary product blanking bucket, all help achieve your individual demands and make your operation easier!
● The original box type high rigidity template with template’s small template deformation and pull rod’s long service life can ensure the performance of die assembly.
● The internally-installed cascade mechanical safety lock will not be influenced by the mold thickness deformation, and the mechanical locking bar has been changed from the traditional compressive type to the tension type, so it is convenient and reliable in use.
● The gear mold regulation unit can regulate mold precisely and with good synchronism.
● The clamping support guide rail uses joist steel structure with high rigidity in order to lower the deformation of the rack.
● The toggle structure optimized and designed with the computer program, cooperating with the regulation of 4 stages and flow during opening and clamping mold of the controller, in order to achieve exceptionally stable and rapid clamping.
● Rotary product blanking bucket can adapt to the workshops and products can be taken out from different places.
● The differential motion clamping unit can improve the mold transferring speed and productivity substantially.
● Ejector pin adjustable unit
● Double cylinder injection: it overcomes the weakness of the traditional non-synchronous injection motion and great inertia, makes the injection and transferring motion more stable and improves the injection precision up to 98.75%.
● The folding type swabbing and injection oil cylinder: it is more compact than the traditional double cylinder structure with reasonable energy consumption allocation./p>
● The ship type bridge guide rail: the injection and transferring adopts the ship type bridge guide rail design with low noise and smooth travel; it is suitable for high speed application; and it can maintain the precision for a long time featuring high locating precision and good repeatability.
● Oil seal: it uses non-rotary sealing technique to prevent leaking.
● The regulation unit at the center of the nozzle: it regulates the nozzle center more conveniently and accurately.
● The rigid connection between injection motion and control valve, in order to lower the fluctuation of the fluid and improve the injection precision.
The oil way design of big bore under no resistance can lower the oil way loss and noise; it uses the advanced configuration, the servo control system, so it features energy saving capacity up to 20-80% and can achieve zero back pressure glue-smelting with plasticizing capacity and plasticizing effect improved by 60% compared with the traditional machine; and it uses a high density filtering unit in order to control the greasy dirt at NASB-9.
● The advanced configuration, the servo system, can save energy up to 20-80%.
● It uses the high pressure filter screen in order to control the greasy dirt at NASB8-9.
● 60 um filter screen has a super strong capacity of receiving pollutant which can be replaced easily.
● The zero back pressure glue-smelting unit improves plasticizing effect and plasticizing capacity by 60% compared with common molders.
● According to the fluid simulation analysis, the design of optimized oil way can achieve a large bore and non-resistance, so its pipeline loss is more than 10% lower than the traditional design and its overall unit noise is more than 6 db lower.
● The new type of oil tank design is in favor of air’s separation, in order to ensure good operation of the servo system, and it is convenient for cleaning.
