Bowing Molding Machine is a plastic processing machine. After the liquid plastic is sprayed out, the plastic body is blown and attached to the mold cavity of a certain shape by using the wind force blown out by the machine, so as to make the product. This machine is called blow molding machine. The plastic is melted and quantitatively extruded in the screw extruder, then formed through the mouth film, cooled by air ring blowing, then pulled by the tractor at a certain speed, and wound into a coil by the winder.
Bowing Molding Machine mostly adopts frequency converter, and the energy-saving way is to save the remaining energy consumption of the motor. It has the advantages of high thickness, corrosion resistance and wear resistance. The lifting unit adopts square frame platform structure, and the lifting frame height can be automatically adjusted according to different technical requirements. The unloading equipment adopts peeling rotating equipment and central rotating equipment, and the torque motor is used to adjust the smoothness of the film for easy operation.

Key Engineering Features
Precision Parison Control
MOOG system with up to 100-point parison control, reducing weight by 10%–15% while maintaining strength.
Multi-Layer Co-Extrusion
1–6 layer die-head design, supports EVOH/PA barrier layers and recycled cores for cost and performance balance.
Servo-Hydraulic System
KEBA PLC with servo drive, delivers 30%–50% energy savings vs. conventional systems.
Rigid Clamping System
FEA-optimized structure ensures uniform clamping force, reduces flash, and extends mold life.
Industry Adaptations
Food & Beverage Packaging
All melt-contact components (screws, barrels, die heads) utilize non-contaminating, corrosion-resistant alloys, ensuring strict compliance with FDA and EU 10/2011 food-contact standards.
Pharmaceutical & Medical Containers
Our IBM and SBM platforms feature automated, oil-free clamping zones and enclosed layouts, easily adapting to ISO Class 8 (Class 100,000) cleanroom environments under strict GMP regulations.
Supply Chain & Quality Assurance Protocol
Premium Metallurgy for Abrasive Resins
Material Grade: Extruder screws and barrels are crafted from premium 38CrMoAlA structural alloy steel.
Surface Treatment: Finished with deep ion nitriding or optional bimetallic alloy coatings (Tungsten Carbide base) to withstand abrasive calcium carbonate masterbatches and high-percentage regrinds.
Strict Pre-Shipment Factory Acceptance Testing (FAT)
72-Hour Stress Test: Every machine undergoes a mandatory 72-hour continuous dry-cycle run and high-pressure hydraulic endurance check prior to dispatch.
Traceable Documentation: Complete FAT data sheets, component calibration logs, and operational video validations are archived and sent to the client 48 hours before loading.
Blow Molding Production Process
Material Conditioning
Resin is dried and homogenized inside a high-torque nitrided screw barrel to prevent thermal degradation.
01
Parison/Preform Generation
Molten polymer is extruded into a vertical tube (EBM) or injection-molded (IBM/SBM), regulated by dynamic wall-thickness programming.
02
High-Pressure Blowing
Heavy-duty clamping units lock the mold while clean, oil-free compressed air (up to 40 bar) inflates the plastic to its final shape.
03
Optimized Cooling
High-velocity cooling channels rapidly solidify the container, ensuring dimensional stability and minimizing cycle times.
04
Automated Deflashing
Finished parts are ejected, and flash/scraps are automatically trimmed and channeled to a granulator for closed-loop recycling.
05
