Haitian Machine - "The machine you need to stand out in global competition!"
- HAITIAN INJECTION MOLDING MACHINE -
 

The HT line of Horizontal, five point toggle injection molding machines cover a range from 100 tons to 3000 tons of clamping force, with barrel capacities from 4 ounces to 1110 ounces. Drawing the expertise from China, Canada, Germany, Japan and USA, these machines know the best value machine for general-purpose injection molding.

- HIGH PRECISION INJECTION UNIT -
 

The HTW series machines offer a large range of injection capacities with accurate 10 stages control. Type A, B and C screws can be selected for different injection capacities. The use of high-resolution linear displacement transducer (0.0394 inches) ensures total repeatability of injection performance. Hydraulic screw motor transmits drive to nitride screw to ensure optimum performance and long life with a wide range of materials. Twin-carriage movement cylinders reduce structural stress.

 

  • 6 (six) injection speed profile and 6 (six) holding pressure profile.
  • 3 (three) witches over mold: Position, Time and Pressure
  • 3 (three) charging steps including 10 (ten) back-pressure digitally control
  • Suck back in two stages
  • Screw speed indication on screen by means of rotary encoder
  • Screw produced using high-precision CNC thread grinder to achieve strong plasticising
  • capacity and homogenous mixing
  • Graphic display for injection speed hold pressure
  • Barrel heat shield
  • Steel hopper with material shut-off mounted on robust, sliding base for easy emptying
  • Water channels to cool barrel throat section
  • Increased plasticising efficiency and ease of barrel purging by using precision-honed barrel.
  • Injection and back-pressure are indicated on gauges and screen.
  • A high-torque hydraulic motor.
- STRONG AND RELIABLE CLAMPING UNIT -
 
  • The toggle mechanism is a proven 5-point design that provides efficient and reliable movement. Harden steel pins and bushings are lubricated by a fully automatic alarmed system.
  • Automatic hydraulic mold-height adjustment is driven by a planetary gear system via the controller to ensure fast and constant settings.
  • The heavy-duty platens are made of ductile iron casting and available with either T-slots or screw holes (SPI). The high-tensile tie bars are made of quality steel harden chromed for long life span.
  • Faster opening/closing without hydraulic shock.
  • Smooth opening and closing design
  • Precise stopping positions.
  • High-speed clamping
  • Low-pressure mold protection
  • Linear transducer for clamp stroke control.
  • Moving platen supported on precision adjustable sliding shoes.
  • Mold setup switch giving low-speed mold opening and closing.
  • Safety guard with mechanical electrical and hydraulic interlock.
  • Complete hydraulic core pulling controls (speed & pressure) with double manifold block.
  • Two core pull programs with limit switch or timer confirming signals.
- ACCURATE AND EFFICIENT HYDRAULICS -
 
  • Using world-renowned hydraulic pumps from Vickers (USA), Yuken, or Haitian's hydraulics system offers reliability, efficiency and accuracy in a super-quiet environment.
  • Hydraulic motors are from SAI (Italy) or STAFFA (England) to ensure supreme reliability. SAI motors are used on injection molding machines up to 480 ton while STAFFA motors are employed in all larger capacity machines.
  • All proportional and directional valves are either Yuken or Vickers.
  • Highly energy efficient
