Best for
Large containers, water tanks, traffic barriers, and heavy-duty hollow products that need side-opening access and large mold handling.
Large Containers
Large Accumulator Production ENS Series for Heavy-Duty Parts
For 20L to 200L+ industrial containers, water tanks, and large hollow products that need high parison capacity and clamping support.
The ENS Series is an accumulator-head extrusion blow molding machine line for large containers and industrial parts. It is used when product size, parison weight, and mold load exceed the range of standard continuous extrusion machines.
When the ENS Series fits best
Not ideal for
Compact packaging lines where floor space, cycle speed, and downstream trimming are better served by smaller production series.
Key technical factors
Review machine footprint, mold loading route, shot capacity, part cooling time, take-out method, and factory crane or handling constraints. Large products often need early layout planning because mold access, cooling, and product removal affect both cycle time and operator safety.
Large-Part Forming
- Accumulator head: Designed for larger parison shots and controlled melt delivery.
- Rigid carriage: Supports heavier molds and stable clamping movement.
- Flow-path design: Die-head design can reduce dead spots and support material or color changes.
Part Control
- Thickness control: Helps compensate for parison sag and reinforce the bottom of large parts.
- Auxiliary support: Eccentric blowing and support pins can be evaluated for complex parts.
- Hydraulic stability: Oil cooling and hydraulic setup are matched to long-run operation.
Operation and Automation
- Servo power option: Can reduce idle energy use depending on product cycle and hydraulic demand.
- Feeding and recycling: Can connect with large crushing and feeding systems.
- Remote diagnostics: Supports troubleshooting with Jonh Huah engineers when configured.
Industrial Components
- Hydraulics: Component selection is matched to machine size and service requirements.
- Pneumatics: Air control brands can be selected by project and regional support needs.
- Control system: Electrical control configuration depends on customer requirements.
