Preform Molding

As a perform molding manufacturer and exporter , we are devote to give our customers best service among perform industries.

Generally, the perform molding main equipments are: injection molding machines, plastic material dryer, material autoloader, cooling system, arefaction system and color machine.

Injection molding machines: we used is the hydraulic clamping machines, and it has clamping system, injection system, robot, electronic controller system.

As the perform mold, is has 6 main parts: injector plate (include moving plat and stable plate).moving plate including core, cooling system, ejector plate and press mold. Stable plate is including cavity, valve plate and hot runner .

Auxiliary machines for injection molding machines to got injection moldings.

a.      Plastic material dryer: for dryer PET original material

b.      Autoloader: it could control the volume of material

c.      Cooling machine: providing enough pressure and watering volume

d.      Air dryer machine for helping dry, and speeder dry material.

e.      Color mix machine: stock color for different color requirements.

Perform molding injection, the PET material should be dried for at least 8 hours then could be melt with good state.

Injection preform molding step:

Melting the material by the screw high speed turning, and the speed is very important for melt , it is too slow, then the PET material will not be melt properly ,if too fast, then the PET material will be burns. Of course the barrel is important for heating.

Injection step: it means injection the melting material to the mould .it need the injection molding machine provide the injection pressure for help the material full in the mould.

Then will need some time for keep pressure for the preform molding.

After that, then cooling the mould, the injection gate on the mold will be closed ,then cooling the mould by air and oil.

Got the perform moldings: this is the last step .some customer need the robot for pick up the mold, some are let the perform molding drop automatically.

 The technological parameter is very important for perform molding. As a perform mold manufacturer for many years, we have rich experience at this area.

Technological parameter is have influence in perform molding quality and quantity.

So, our injection molding machine operator will high control the injection weight, balance weight, screw speed, injection pressure ,dry and mould temperature ,also other important elements.
