Real-time fault diagnosis and program optimization, with cross-ocean response and second-level resolution.
Preforms are automatically loaded from the preform hopper, where bulk preforms are stored. They are then transferred to the blow molding machine via conveyor. From there, the preforms move to the heating oven through a star wheel, which allows each preform to be accurately transferred to the preform holder.
Near-infrared (NIR) heating with dense heat radiation for more uniform and optimized preform heating.
Heating oven adopts Swiss imported infrared ceramic fully enclosed reflection channel (more efficient heating; compared to stainless steel reflectors, ceramic reflectors reduce energy consumption by 10%–30%)
Balanced Heating Mandrel Technology (National Invention Patent)
The mandrel operates smoothly with high rotational concentricity and no eccentric movement throughout the process. This precision design achieves the industry's smallest heating pitch of 38.1mm, significantly reducing heating power consumption and maximizing energy savings.
The heating conveyor runs continuously. Once the preform reaches its optimal temperature, the transfer unit moves it to the internal conditioning station for inner wall temperature adjustment via infrared heating rods. After internal heating, the preform is immediately transferred to the blow mold for stretch blow molding. This continuous synchronous process ensures nonstop high-efficiency production.
After the blow molding cycle is completed, finished bottles are automatically extracted from the blow mold by the take-out unit and placed onto a rolling conveyor. The conveyor system can be seamlessly integrated with downstream equipment, including filling lines or leak testing units, enabling fully automated production flow.
Automatically stabilizes heating lamps against power fluctuations, ensuring uniform heat distribution and consistent thermal output throughout operation.
The low-pressure air source for operating pressure is supplied by recovering high-pressure blowing exhaust through the air recovery system, eliminating the need for a separate low-pressure air compressor.
The machine is equipped with an automatic centralized lubrication system. Through the user interface (HMI) , operators can set the lubrication interval time according to production requirements. Once programmed, the system will automatically release the precise amount of lubricant to the mold box and other critical moving components without any manual intervention. This ensures consistent lubrication, reduces wear, extends machine life, and minimizes maintenance downtime.
