HP-L series fully automatic linear blow moulding machine is the most stable two-step fully-automatic pet stretch-blow moulding machine(preheat). It has two to eight cavities and the maximum capacity of the products is 2L. It can blow PET bottles for carbonated, mineral, pesticide, cosmetics, wide-mouth, hot filling, and other packing containers.

The advantages

1. Automatic perform input and ready bottle output system.
Machine adopt with the overall structure of super-standard anti-vibration design, high-speed operation state of the machine will shake down to a minimum.

2. Machine adopts modular assembly method, greatly decrease the local amendments due to technological improvements when the machine is on processing.

3. The structure of machine oven adopt the international most advanced energy-saving technology of infrared radiation heating, temperature control with automatic negative feedback, closed-loop regulation model.

4. Automation controlling item adopts international high-end computer system, heating, collecting and measuring perform temperature with simulation input and output module.

5. Man-machine interface displays current production situation, available for on line switching, parameter modification and production accounting, with automatic alarm, automatic fault detection and diagnose.

6. Special designed small machine frame for small bottle up to 600ml with higher output capacity.  And another for up to 2L bottles.

7. Multi cavity machine option: 2cavity fully automatic blowing machine, 4cavity fully automatic machine, 6cavity fully automatic machine and 8cavity fully automatic machine.

3. Preform Transfer

Servo-driven system:More precise and faster to transfer preform.

Special chain and chain connection guarantee chain system precision and extend chain system lifespan.

Self-lubricating bushing and sealed bearings.

Quick change of robot clips, mould & star-wheels(tool-less) for different bottle

4.Clamping & Stretching System

Toggle structure & pressure increase device:Faster and stronger clamping to avoid disconnected parting surface.

Combination valve:Faster air inlet and very quick air exhaust.

Individual cavity blowing, individual cavity stretching, individual cavity pre-blow are all separately adjustable.

Inbuilt bigger air tank for higher output

Unique low pressure air pressure monitor

Special solenoid valve to cut power and outlet all air for safety is installed.

To save energy and to avoid adverse effect on neighbouring cavities, relevant cavity does not blow if no preform in that cavity.
