Dana Making Machine Manufacturer | Plastic Granule Extruder & Pelletizing Line in India
Dana Making Machine Manufacturer
A Dana Making Machine (plastic granule/pelletizing line) converts clean plastic scrap into uniform granules used by converters across India. A proven manufacturer supplies robust extruders, precise filtration, and reliable pellet cutting systems matched to your polymers (LDPE/LLDPE, HDPE, PP, HIPS, ABS, etc.). Evaluate throughput (kg/hr), melt quality, energy per kg, automation level, and after-sales support before finalizing.

Working Principle & Process Flow of Dana Making
Scrap is inspected, size-reduced, and dried before metered feeding into a vented single or twin-screw extruder. Plastic is melted, filtered (manual/automatic screen changer), and devolatilized; the homogeneous melt is then pelletized via strand or die-face cutting and cooled (water bath, water-ring, or air-cooling). A cutter and classifier deliver uniform granules with controlled MFI. SCADA/PLC logs kWh/kg, melt pressure, and alarms for traceability and preventive maintenance.
Types of Dana Making Machines
- Single-Screw Vented Extruder – Versatile workhorse for LD/LLDPE, HDPE, and PP; simpler operation, competitive capex, stable output.
- Twin-Screw Co-rotating Extruder – Intensive mixing for filled/colored/ABS/HIPS streams; excellent dispersion and additive dosing.
- Strand Pelletizing Line – Melt strands through water bath → air knife → pelletizer; clean cut and easy size control.
- Die-Face Hot-Cut / Water-Ring – Compact footprint, minimal strand handling, ideal for film regrind and higher throughputs.
- Two-Stage Extruder – Agglomerator/force feeder + extruder with vacuum degassing for high-moisture or printed film scrap.
Key Features & Specifications
- High-efficiency drives with VFDs; documented energy usage (kWh/kg) for cost benchmarking.
- Automatic or hydraulic screen changer (single/dual piston) to maintain melt cleanliness and reduce downtime.
- Vacuum degassing and multi-zone barrel heating for odor reduction and consistent MFI.
- Gravimetric feeding & masterbatch dosing for accurate color/filler addition.
- Pellet cutting options – strand, hot-face, or water-ring – with automated speed synchronization.
Applications of Dana (Plastic Granules)
- Film & packaging converters using rLDPE/rLLDPE for carry bags, liners, and liners with controlled gauge and printability.
- Injection moulders producing household items, crates, caps, and industrial components in rPP/rHDPE with stable dimensions.
- Sheet/thermoforming units for trays and disposable items in HIPS/PP with uniform thickness and impact properties.
- Electrical & appliance accessories (non-critical) where consistent color dispersion and tensile/impact balance are essential.
Benefits of Choosing a Specialist Dana Machine Manufacturer
- Lower production cost via energy-efficient drives, heat insulation, and optimized screw design.
- Superior pellet quality from controlled filtration, degassing, and synchronized cutting systems.
- Higher uptime with standardized spares, remote diagnostics, and quick-change screen systems.
- Faster ROI through stable throughput, minimal rejections, and documented performance guarantees.
Manufacturers & Suppliers in India
Indian manufacturers offer complete pelletizing solutions—from force feeders and agglomerators to screen changers, extruders, and pelletizers—backed by commissioning, operator training, and AMCs. When comparing suppliers, seek proof of performance (trial reports), screw metallurgy, wear protection, and local service coverage. Popular upgrade options include stainless steel contact parts, auto-dosing, moisture analyzers, water-treatment skids, and SCADA integration for production analytics.
Maintenance & Safety Tips
- Inspect gearbox oil level, heaters, thermocouples, and barrel zone balancing per shift; log deviations.
- Clean screen changer channels; maintain spare screens by mesh size and batch traceability.
- Calibrate gravimetric feeders and check pelletizer knife sharpness for uniform cut and low fines.
- Follow LOTO procedures; shield hot surfaces; verify emergency stops and guards weekly.
- Stock critical spares—heaters, RTDs, seals, knives, breaker plates—to reduce MTTR.
FAQs – Dana Making Machine
1. Which pelletizing method should I choose—strand or die-face?
+
Strand is simple and clean with easy size control; ideal for rigid regrinds. Die-face/water-ring is compact and better for films/soft melts at higher throughputs with less handling.
2. How do I size the extruder for my scrap?
+
Match screw diameter/L:D, motor HP, and degassing to polymer type, contamination, and target kg/hr. For film feeds, prefer force feeder/agglomerator and vented barrels.
3. What improves pellet quality and reduces odor?
+
Use fine filtration (80–200 mesh), vacuum degassing, correct temperature profile, and maintain consistent feed moisture. Keep screen packs and knives in good condition.
4. Can one line run multiple polymers?
+
Yes, with recipe control and changeover SOPs. Separate screen packs, temperatures, and cleaning protocols help maintain color/MFI stability across runs.
5. Which KPIs should I track?
+
kWh/kg, average throughput, melt pressure trends, pellet size distribution, fines %, and unplanned downtime. SCADA dashboards help visualize and improve these metrics.
