PP PVC PE PS TPL color plastic spoon injection molding machine / making malchine

Main features of the machines

• Screw of big length to diameter ratio,uniform plastication and high plasticizing capability.
• Multi step adjustment of injection speed or pressure .
• Back pressure control of molten plastic.
• Double toggle mold closing system with a large force magnification ratio and a large stroke ratio.
• Very good speed characteristic of high speed mold closing and low pressure mold protection.
• Various kinds of hydraulic ejectors.
• Double proportional. load sensitive hydraulic circuit.
• For big sizes of machines there are several oil pumps in a group. use proportional value to compensate the difference of pressure or flow between pumps.
• Tripe interlock of mechanic. electric and hydraulic devices.
• Hydraulic knockout core device and rotary mold-parting from the work piece device.
• Using the computer. electric and hydraulic elements of famous brands in the world.

  Main datas of the injection molding machine

 Note:

• Theoretical injection volume=(section area of the barrel)*(stroke of the screw)
• The injection shot weight should be 91% of the theoretical shot volume for polystyrene(PS).
• The plasticizing capacity and injection rate are the values for polystyrene(PS).
