Large Hollow Part Blow Molding Machine | Chen Way
Accumulator blow molding machine for large hollow products such as tabletops, sofa and hoop bases, infant car seats, mannequins, ice chests and packaging parts.
Large Blown Finished Product Accumulator Type of Blow Molding Machine
Accumulator die head type of blow molding machines are ideal for manufacturing large and structurally complex hollow products. Their applications span various industries, including tabletops, LCD screen packaging materials, basketball hoop bases, sofa bases, infant car seats, and mannequins. Products manufactured using this technology offer high durability, resistance to aging, and superior impact performance. They are particularly effective as protective packaging materials, significantly enhancing product safety during both transportation and long-term use.
Molding Principle
The machine employs an accumulator extrusion system that temporarily stores molten plastic in an accumulator cylinder (die head). Once the material reaches a preset volume, a plunger mechanism rapidly extrudes it in a single stroke to form a complete, robust parison, which is then immediately blow-molded. This method ensures a more uniform temperature distribution across the parison and prevents molding defects caused by uneven temperature. It is particularly suitable for manufacturing large-scale or heavy-duty hollow products.
Applications
Accumulator head blow molding machines are widely utilized across industrial products, transport packaging, household and commercial goods, and the toy industry. They are particularly ideal for the storage and transportation of hazardous liquids, such as chemicals, detergents, and various industrial fluids, ensuring maximum safety and stability during handling. Whether for industrial, commercial, or everyday needs, this technology delivers reliable, consistent molding quality, demonstrating high flexibility and practical value.
Specification
Die Head: Accumulator / Vertical Ram Type
β Built-in Accumulator Chamber: The die head features an integrated accumulator chamber that stores a large volume of molten plastic in a short period and extrudes it rapidly in a single shot. β Ram Type Push Mechanism: Utilizes a vertical plunger (Ram Type) structure for a stable stroke, ensuring consistent output and weight for every cycle. β Optional Parison Programming: Can be equipped with a multi-point wall thickness control system (such as the Moog Parison Controller) to adjust material distribution across different sections based on product design requirements.

Machine Sizing for Large and Complex Hollow Products
This accumulator machine targets large, structurally complex hollow products: tabletops, sofa bases, basketball hoop bases, infant car seats, mannequins, lampshades, ice chests and protective packaging for LCD screens. Such parts need a heavy parison delivered quickly so it does not sag before the mold closes, and Chen Way's Supersize accumulator series covers the largest articles. Long parts may also need the extruder frame height adjusted to the parison length.
Part dimensions, shot weight, wall-thickness pattern and inserts decide the extruder, accumulator volume and platen size for each project; the output figures in the specification table are extruder throughput, not parts per hour. For water storage rather than furniture or packaging parts, compare the one-piece water drum machine. Send part dimensions and shot weight with your inquiry to receive a machine study.
