One Piece Water Drum Accumulator Type of Blow Molding Machine
Accumulator Head Blow Molding Machine for One-Piece Water Drum
The One-Piece Water Drum Accumulator Die Head Blow Molding Machine is specifically engineered to produce plastic drums and hollow containers up to 200 L. Utilizing an accumulator extrusion system, the machine provides stable control of parison weight and wall-thickness distribution, ensuring consistent product dimensions and structural integrity. Featuring a specialized mold design for one-piece processing, the drum body and lid can be formed simultaneously in a single cycle. This equipment offers stable operation, high production efficiency, and operational flexibility, making it ideal for water towers, tanks, industrial containers, and other liquid storage applications, helping meet mass-production demands and enhance overall productivity.
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
● 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. ● Ram Type Push Mechanism: Utilizes a vertical plunger (Ram Type) structure for a stable stroke, ensuring consistent output and weight for every cycle. ● 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.

Accumulator Machine for One-Piece Water Drums
This accumulator die head machine is listed by Chen Way for one-piece plastic water drums and similar hollow liquid-storage containers, such as water towers, water tanks and industrial containers. Because the accumulator die head pushes out the full parison in one stroke, parison weight and wall distribution can be held steady from cycle to cycle, which matters for large containers that must hold liquid reliably.
Drum capacity, mold design, wall weight and any lid or closure arrangement should be confirmed in the specification, because they decide the screw size, accumulator volume and clamping unit. Production footage from a customer in the Philippines shows water tanks made on this type of machine. For other household items, compare the household products application, and send the tank volume, wall weight and closure design to request a machine proposal.
