Die Head

Raw material: 38CrMoAIA alloy steel with nitrogentreat ment, 25 HRC, brittleness≤2.
Center feeding extrusion, no blind angle, fast color andm aterial changing. 3. Origin from in-house at high precision CNC center.
Heating bands evenly distributed to efficiently maximizeplasticizing capacity and avoid material deformation at this critical stage of the extrusion.
 

Clamping System

 
Toggle located on horizontal platens driven byhydraulic cylinder provides movement for clamping, which ensures the rigid feature of the platen and also keeps equal force distribution of platens, without deformation.
All clamp and carriage movements are on liner guiderail, ensuring steady and accurate action, less resistance and fast speed.

Hydraulic System

External heat-exchanger
Hydraulic vales, main system vane pump, andmotor; oil level gauge with thermometer.
Automatic oil-temperature control bywater-flow adjustment in the exchanger. 4. With separate hydraulic pack for parison controlling. 
Servo system (inverter drive + internal gear pump + servo motor), saving energy. 

Automatic trimming system

 
 
Special blowing unit make the bottle extra plasticeasy take out.
Rolling cutting neck device on machine orcooperate with conveyor both available.
Punching cutting device give a smooth and flatmouth avoid leakage.
Bottom trimming as well as handle trimming,transfer the waste plastic properly.

Electrical System

 1. Well-known brands like MITSUBISHI, SCHNEIDER, weinview are used to coordinate with machine, highly raising production efficiency.
2. HMI andPLC
a. Temperature control: Speed Control Motoris adapted to regulate the rotation speed of the preform in the oven to get it fully heated.
b. Time setting
c. I/O Monitoring 

Cooling System

 
Rubber hose for water cooling lines, no rust, noleakage, absorbing machine shaking during running,long lifetime, movable.
Machine electric box,extrusion system,feeding area,oilp ump,moulds ,blow pins all have proper cooling system t o make the machine in good conditions.
