Automatic Blow Molding Machine Auxiliary Equipment
Complete your production line with these essential support systems
Hopper Dryer
Pre-dries plastic materials to remove moisture before processing, ensuring optimal material quality and preventing defects in finished products.
Water Chiller
Maintains precise temperature control for cooling molds and machinery, critical for consistent product quality and cycle time optimization.
Mould Temperature Controller
Regulates mold temperature with high precision to ensure uniform wall thickness and superior surface finish on blown containers.
Dehumidifying Machine
Controls humidity in production areas to prevent moisture absorption by hygroscopic materials like PET during processing.
Crusher
Recycles production scrap and rejects by grinding them into reusable granules for cost-effective material recovery.
Vertical Color Mixing Machine
Ensures homogeneous blending of masterbatch colors with virgin material for consistent product coloration.
High Pressure Air Compressor
Generates the high-pressure air (25-40 bar) required for the blow molding process to form container shapes.
Low Pressure Air Compressor
Provides low-pressure air (8-10 bar) for machine operations like part ejection and conveyor systems.
Air Dryer
Removes moisture from compressed air to prevent water spots and defects in blown containers.
Air Filter
Purifies compressed air by removing oil, dust and particulates that could contaminate products.
Screw Compressor
Provides continuous, energy-efficient compressed air supply for high-volume production environments.
Supercharger
Boosts air pressure when additional blowing force is required for large or complex container designs.
Air Storage Tank
Stabilizes air pressure and provides reserve capacity to handle peak demand during production cycles.
