Single Station, Double Station & Co-Extrusion Configurations
Single-Station vs. Double-Station Systems
Platforms ship in single station and double station layouts to match target output and floor space. A double station automatic extrusion blow molding machine high output HDPE layout doubles daily bottle yield on one footprint for high-volume packaging.
| Performance Metric | Single-Station Platform | Double-Station Platform |
|---|---|---|
| Plant Footprint | Minimal floor space required | ~35% larger overall footprint |
| Target Container Size | Medium to large (5L to 30L) | High-speed small/medium (100ml to 5L) |
| Output Capability | Standard batch runs | Up to 100% higher container output |
| CapEx vs. OpEx | Lower initial equipment investment | Lowest per-unit labor and energy cost |
Accumulator Head Technology
For heavy-duty packaging from 20 L plastic jerrycans up to 1,000 L IBC tanks, accumulator extrusion head setups deliver high shot-weight precision and structural integrity.
- FIFO (First-In, First-Out) Flow Design: Prevents polymer stagnant zones and thermal degradation during long melt cycles.
- Rapid Parison Ejection: Eliminates parison sag on large-scale HDPE melts, ensuring wall thickness uniformity.
- Fast Color Swaps: Streamlined melt channels reduce resin flush times when switching masterbatch colors.
Multi-Layer Co-Extrusion (2 to 6 Layers)
Our multi-layer co-extrusion blow molding machine technology helps you meet strict packaging regulations and sustainability goals without sacrificing bottle strength:
- EVOH & Nylon Barrier Layers: Prevents solvent permeation, gas migration, and odor loss in agrochemical, fuel tank, and chemical containers.
- PCR Layer Integration: Sandwich up to 80% Post-Consumer Recycled (PCR) HDPE inside the core layer, reserving virgin resin for the inner and outer surfaces to meet recycled-content packaging targets.
- Continuous View-Line Extrusion: Ingests a clear strip down the container body, giving end-users an accurate visual indicator of fluid levels.
Conformal-cooled molds and quick-change plates align with rated clamping force and auto deflashing trim paths on the line.
Precision Tooling and Mold Cavity Integration
High-precision blow molds are engineered for direct integration with each automatic HDPE blow molding machine setup, eliminating integration delays and maximizing cooling performance across every mold cavity.
Premium CNC Mold Construction
Custom EBM molds use high-grade metals for high-volume container runs:
- Aerospace-Grade Aluminum (7075-T6): Fast thermal conductivity for high-mold cavity packaging lines.
- S50C & Alloy Tool Steels: Pinch-off areas, neck rings, and bottom inserts for clean, reliable auto deflashing over millions of cycles.
Conformal Cooling Design
Conformal cooling channels target heavy wall sections—handles, neck threads, and bottom pinch-offs:
- 15% to 20% Faster Cycles: Rapid heat dissipation shortens holding times and speeds part ejection.
- Uniform Temperature Control: Even cooling across the entire mold cavity prevents warping and drop-test failures.
| Tooling Feature | Construction Standard | Plant Impact |
|---|---|---|
| Material Build | 7075 Aluminum / S50C Steel | High thermal transfer with durable pinch-off edges |
| Cooling System | Conformal CNC-milled channels | Cuts cooling time by up to 20% |

Frequently Asked Questions
5L HDPE Jerrycan Cycle Time on Double Station Machines
On our double station extrusion blow molder, a standard 5L HDPE jerrycan (130g–160g) averages a 14 to 18-second total cycle time. Utilizing a double-station 2+2 cavity mold configuration, our automatic HDPE blow molding machine yields 700 to 900 containers per hour. Actual output depends on bottle wall thickness and plant chilled water temperature.
Processing PCR Recycled HDPE Resin
Yes. BlowPacker machinery processes post-consumer recycled (PCR) HDPE without sacrificing container strength or surface finish. Our multi-layer co-extrusion heads encapsulate up to 80% PCR resin in the center layer, placing virgin HDPE on the inner and outer surfaces. This maintains product integrity, drop-test performance, and UN-rating compliance while reducing raw material costs.
