Thank you very much for you purchase of the HAITAI Injection Machine.
The injection machine is good in capacity, superb in workmanship, and easy to operate.
The inside five point toggle clamp unit has many patent technology of our company, which enable the
machine to have a rigid structure and to be difficult to deform, other feature like force symmetry, smooth
movement, low noise. The uses of hollow spherical structure of the fixed platen design increase the
precision of the products. The flexible tie bar and nut to make sure that the tie bar free from fracture. The
widening space of open stroke and tension bar, therefore the use of the scope has been further improved.
The twin toggles of clamp structure that is five points arranged slanting is patent technique of our
company. The clamp unit is good in rigidity, no distortion, symmetry in force, less in noise and steady to
run. The fixed platen is designed hollow
The double balanced injection unit has stable performance and rigid structure. The low-speed-high
torque motor direct drives plasticizing. The capacity of plasticizing has been improved with a high
efficiency. The patent technology of double injection unit save the energy and increase the injection speed.
The use of high, medium and low-pressure screw is able to meet the thick-walled, thin-walled products
molding requirement.
The heat resistance type heated ring is PID controlled by computer. It features as heating fast, stable
temperature, the sensitive and accurate temperature conversion.
The "Mechanical - Electrical - Hydraulic" safety device ensure safe and reliable. The machine has a
reasonable layout and beautiful appearance. It can be easily operated and maintained.
The speed of opening/closing mold, change of pressure, the amount of pre-plasticizing, the switch
point from injection to holding, and the multi stage of injection is controlled by computer and the
movement is finished by the hydraulic system. These features result in a high precision, fast response,
integration of "mechanical –electric-hydraulic‖ advanced control systems.
The hydraulic system incorporates proportional pressure control; the main components are
international brand-name products.
