Structural Introduction

The TECBLOW series features an easy-to-use,simplified user interface for intuitive machine control.The autoloading preform system incorporates a central rotation mechanism,ensuring stable heat distribution and uniform heating across the preform wall from every angle.Our most advanced transfer technology allows preforms to be picked directly from the heating oven and delivered to the blowing molds in a single step-automatically adjusting to preform distance variations.This fully electric system uses mechanical claw technology operated by servo drives,eliminating complex mechanisms and reducing spare parts usage.The same mechanical claw technology is used at the bottle take-out station after blowing,requiring no pneumatic energy,which enhances component longevity and reduces future spare parts costs for customers.

TEC BLOW II SERIES ADVANTAGES

Heating Oven Advantage

Balanced heating mandrel technology;
Cam controls preform active mandrel loading;
NIR heating,intensive heating,PET preform much more uniform heated and optimized.
Heating oven adopt Swiss infrared ceramic reflector technology(heating efficiency much higher than SS reflector,and power consumption 10%-30% lower than traditional type.
38.1mm-the smallest heating distance in blowing machine field, power consumption is much lower than 50.8mm heating pitch.

Preform Transfer Advantages

Continuous preform transfer technology(national patent)for uninterrupted operation.
Screw preform separation system with one-way rotation, reducing wear and mechanical movement.
Fast transverse movement structure with bumper design for smooth and reliable transfer.
Fully electric system using servo-driven mechanical claw technology,eliminating complex mechanisms.
Servo stretching for accurate positioning,ideal for lightweight bottle forming.
Automatically adapts to preform distance variations without additional adjustments

Active Mandrel Advantage

The preform mandrel operates with exceptional stability and high rotational concentricity,ensuring no off-center movement during rotation.This precision design allows for a heating pitch of only38.1mm-the smallest in the industry-significantly reducing heating power consumption and maximizing energy savings.

Four Plate Servo Clamping

The servo motor drives the gearbox to actuate mold clamping,in synchronization with the bottom cam for fast mold opening and closing.
