LDPE Dana Making Machine Manufacturer – Sunrise Extrusion
Sunrise Extrusion is a trusted LDPE Dana Making Machine Manufacturer offering efficient recycling and granulation solutions for LDPE film waste, carry bags, packaging scrap, stretch film, agricultural film, liner waste, and other low-density polyethylene materials. A well-designed LDPE Dana Making Machine converts sorted plastic scrap into uniform recycled granules that can be reused in film extrusion, moulding, pipe manufacturing, sheet production, and many other plastic-processing applications.
For recyclers, the quality of the final dana depends on more than melting plastic. Stable temperature control, effective filtration, screw design, cooling performance, and accurate pellet cutting all influence granule consistency. As an experienced LDPE Dana Making Machine Manufacturer in India, Sunrise Extrusion focuses on dependable output, lower operating cost, operator safety, and configurations that suit actual recycling requirements.
How an LDPE Dana Making Machine Works
The process begins with collection and sorting of LDPE scrap. Materials such as printed film, post-industrial trim, stretch film, and clean production waste are checked to remove paper, metal, dust, moisture, and incompatible polymers. Clean input material is essential because contamination can block filters, damage the screw, and reduce the quality of recycled dana.
After sorting, the material is fed into the cutter-compactor or hopper. The compactor cuts lightweight film into smaller pieces and uses controlled frictional heat to densify it. This creates a steady, compact feed for the extruder and avoids uneven feeding, which is common with loose plastic film.
Inside the extruder, a rotating screw carries the material through heated barrel zones. The LDPE softens gradually and becomes a uniform melt. A hydraulic screen changer or manual filtration system removes fine impurities from the molten plastic. The filtered melt then passes through a die head and is converted into strands or pellets through a water ring, strand pelletizing, or underwater pelletizing arrangement. Finally, the granules are cooled, dried, screened, and collected for packing.
A quality Plastic Granule Manufacturing Machine maintains the right balance of heat, pressure, residence time, and screw speed. Excessive heat may degrade LDPE and produce dark or brittle granules, while low heat can lead to incomplete melting and uneven pellets.
Machine Configurations and Available Types
Sunrise Extrusion can provide a Plastic Dana Machine in configurations based on scrap type, required capacity, automation level, and desired output quality. Single-stage machines are suitable for cleaner post-industrial scrap, while double-stage extrusion lines are preferred for printed, contaminated, or post-consumer LDPE waste because they offer improved filtration and melt homogenization.
Common configurations include:
- Cutter-compactor recycling lines for LDPE film, bags, and stretch film
- Agglomerator-fed extrusion lines for dry, lightweight scrap
- Single-stage granulation systems for clean production waste
- Double-stage pelletizing systems for better filtration and consistent quality
- Water-ring pelletizers for compact operation and rounded granules
- Strand pelletizing systems for applications requiring controlled pellet size
- PLC-controlled automatic lines with variable-speed drives and sensor-based monitoring
As a reliable Plastic Granule Making Machine Manufacturer, Sunrise Extrusion helps buyers select the most suitable layout instead of offering a one-size-fits-all solution.
Key Features and Technical Specifications
A modern LDPE Dana Making Machine should be built for continuous production, easy operation, and energy-efficient recycling. Sunrise Extrusion designs machines with practical engineering features that support stable output and reduced downtime.
Typical technical specifications may include:
- Production capacity: approximately 100 kg/hr to 1,000 kg/hr, depending on model and material condition
- Extruder screw diameter: selected according to throughput and scrap density
- Screw and barrel material: nitrided or hardened alloy steel for wear resistance
- Heating system: ceramic band heaters, cast aluminium heaters, or energy-efficient heating zones
- Temperature control: multi-zone PID controllers for accurate melt management
- Motor drive: AC motor with VFD for adjustable screw RPM and lower power consumption
- Filtration: hydraulic screen changer, laser filter, or multi-screen arrangement
- Pelletizing: strand, water-ring, or customized pellet-cutting system
- Cooling: water tank, water ring, blower, or centrifugal dryer
- Control panel: PLC/HMI panel with overload protection, alarms, and production monitoring
The output of a Plastic Dana Machine Manufacturer should be evaluated not only by hourly capacity but also by pellet uniformity, colour stability, filter life, electricity consumption, and the ability to process varying scrap conditions.
Benefits for Plastic Recycling Businesses
Investing in a high-performance LDPE Dana Making Machine Manufacturer solution allows recycling businesses to convert waste into valuable reusable raw material. It reduces landfill burden, supports circular manufacturing, and improves profitability through material recovery.
Key benefits include higher material utilization, consistent recycled granules, lower dependence on virgin polymers, and better control over in-house scrap. Automatic feeding and PLC-based controls also reduce manual handling and support safer, more repeatable production. Properly matched screw geometry and heating zones help reduce unnecessary power consumption while maintaining stable output.
For manufacturers using film scrap every day, a recycling line can bring substantial operational savings. Instead of disposing of trim waste or rejected rolls, businesses can process the material and reuse it in suitable non-critical product layers, blends, or new product formulations.
Applications of Recycled LDPE Dana
Recycled LDPE granules produced by a Plastic Granule Manufacturing Machine are used across many industries. Depending on cleanliness, melt flow, colour, and filtration level, the dana may be used for carry bags, garbage bags, packaging films, agricultural films, tarpaulins, irrigation accessories, pipes, sheets, moulded household items, cable compounds, and extrusion-coated products.
The final application should always determine the required machine configuration. For example, packaging-film recyclers may need better filtration and colour control, while moulding applications may focus more on melt flow consistency and pellet strength.
How to Select the Right Machine
Before choosing a Best LDPE Dana Making Machine Manufacturer, assess the type and volume of scrap available. Determine whether the material is clean factory waste, printed film, washed post-consumer film, or moisture-containing agricultural scrap. The machine capacity should match realistic daily feedstock availability rather than only the highest advertised output.
Also consider pelletizing method, level of automation, filtration requirement, floor space, power availability, water circulation arrangement, spare-part accessibility, and service support. A Top LDPE Dana Making Machine Manufacturer will study your material sample and recommend the right screw design, die arrangement, and processing stages for dependable production.
Maintenance and Safety Tips
Regular maintenance protects output quality and extends machine life. Clean the screen changer at planned intervals, inspect heaters and thermocouples, lubricate gearboxes as per schedule, and check the cooling-water system for blockage or leakage. Monitor motor load and melt pressure; sudden changes can indicate contamination, blocked screens, or wear in the screw and barrel.
Operators should wear gloves, safety shoes, eye protection, and fitted clothing. Emergency-stop buttons, thermal overload protection, guarding around rotating parts, and lockout procedures during maintenance are essential. Never clean or adjust the die, cutter, or pelletizer while the line is operating.
