HDPE Dana Plant Manufacturer
A specialized HDPE Dana Plant Manufacturer supplies complete reprocessing lines that convert HDPE regrind/flake into uniform granules (dana) for pipes, drums, jerrycans and houseware. Configurations include cutter-compactor feeding, vented single/dual stage extrusion, precision melt filtration, and water-ring or strand pelletizing. While evaluating Indian suppliers, compare throughput (kg/hr), energy (kWh/kg), filtration mesh, automation (PLC-SCADA), safety interlocks and service reach for predictable OEE and fast payback.
Working Principle & Process Flow
Typical HDPE dana plants follow a robust flow: sorting & metal separation → size reduction & washing → drying → densified feeding → plasticizing in a vented extruder → melt filtration → pelletizing → drying & classification → bagging. Vacuum degassing removes moisture/volatiles; dual-piston automatic screen changers stabilize pressure; melt pumps maintain constant output; water-ring die-face systems deliver compact, uniform pellets with minimal tails.
Types of HDPE Dana Plants
- Single-screw vented pelletizing line for washed HDPE flakes & regrind (general purpose).
- Two-stage (mother–baby) extruder for high-contamination streams and finer filtration.
- Cutter-compactor integrated line to stabilize feed bulk density & improve throughput.
- Water-ring die-face pelletizer for small, spherical pellets & automatic drying.
- Strand pelletizer with water bath & air knife for rigid flakes, ABS/PS/PC blends & engineering resins.
Key Features & Specifications
- Energy-efficient IE2/IE3 motors with VFDs; documented kWh/kg benchmarks for HDPE streams.
- Automatic dual-piston screen changer (60–200 mesh) for cleaner melt & stable pressure.
- Vacuum degassing, multi-zone temperature control & melt pump for steady output/MFI consistency.
- Bimetallic wear-resistant barrels/screws; SS304 contact parts where needed; quick-change die.
- PLC-SCADA with recipe management, alarm logs, preventive maintenance & remote diagnostics.
Applications of rHDPE Dana
- Blow moulding of jerrycans, drums, bottles & fuel tanks (non-critical grades as specified).
- Pipe extrusion, corrugated ducts, cable conduits, and protective sleeves (as per buyer specs).
- Injection moulding of crates, pallets, caps/closures & household items with tailored MFI.
- Sheet/profile extrusion for boards, partitions & industrial liners.
Benefits of Partnering with an HDPE Dana Plant Manufacturer
- Lower conversion cost with dependable recycled feedstock & high scrap monetization.
- Consistent pellet quality—tight size distribution, stable MFI & fewer gels/black specks.
- High uptime via automated filtration, melt pump control & recipe-driven changeovers.
- Audit-ready traceability with data logging, EPR alignment & comprehensive safety interlocks.
Manufacturers & Suppliers in India
Reputed Indian OEMs offer turnkey execution—layout drawings, utilities list, installation, commissioning & operator training. Compare film vs. rigid throughput, filtration capability, degassing effectiveness, pelletizer selection, water-recycling options and response SLAs. Popular upgrades include odour control, gravimetric dosing, metal separators and online pellet classifiers for consistent downstream performance.
Maintenance & Safety Tips
- Track barrel pressure/temperature trends & motor loads; investigate deviations immediately.
- Replace screens proactively; monitor ΔP to avoid surges & die-face fouling.
- Clean water-ring/strand path routinely; service knives, die plates & pelletizer bearings as per schedule.
- Enforce LOTO, PPE & hot-surface protocols; brief teams on emergency stop procedures.
- Maintain labelled stocks of heaters, thermocouples, seals, knives & pump spares in dry storage.
FAQs – HDPE Dana Plant Manufacturer
1. What plant capacity should I choose for HDPE reprocessing?
+
Match kg/hr to stable scrap availability, shift pattern & product mix. For mixed HDPE streams with higher contamination, consider a two-stage extruder with finer filtration and robust degassing.
2. Die-face (water-ring) vs. strand pelletizer—what’s better for HDPE?
+
Water-ring delivers compact layout & uniform pellets—great for high-throughput lines. Strand suits rigid flakes & engineering resins, and allows easy visual control over strand quality.
3. How do I control odour and moisture in rHDPE?
+
Use effective washing/drying, vented barrels & vacuum degassing; maintain residence time and stable temperatures. In some cases, additives and odour control modules help reduce residual volatiles.
4. What filtration mesh is recommended for HDPE?
+
Typical ranges are 60–120 mesh for rigid regrind and up to 200 mesh for cleaner streams—final selection depends on downstream specifications and desired pellet cleanliness.
5. What documentation should my purchase contract include?
+
P&ID, GA layout, utilities list, FAT protocols, safety compliance, spares list & performance guarantees tied to throughput, energy and pellet quality (MFI/IV, contamination limits).
