Plastic Pelletizer Machine for HDPE and LDPE
Plastic pelletizer machine for HDPE and LDPE converts washed films, bags, liners, and raffia into uniform, high-strength pellets. Suraj Industry builds robust, energy-efficient lines that deliver stable melt, consistent pellet geometry, and dependable 24×7 recycling performance across India.
Working Principle and Process Flow of Plastic Pelletizer Machine for HDPE and LDPE
Clean, dried HDPE/LDPE flakes or film are metered into the hopper, plasticized in multi-zone heated barrels, filtered through an automatic screen changer/gear-pump, and extruded via die. Strands are water-cooled or hot-cut, then pelletized and dried for reuse.
Types of Plastic Pelletizer Machines for HDPE and LDPE
- Single-screw pelletizing line for films, bags, and regrind
- Twin-screw compounding pelletizer for blends, fillers, and additives
- Vented extruder for moisture/volatiles control in washed film
- Water-ring die-face cutting system for consistent round pellets
- Strand pelletizing system with adjustable cut length and easy inspection
Key Features and Specifications of Plastic Pelletizer Machine for HDPE and LDPE
- Corrosion-resistant stainless contact parts and heavy-duty frames
- Optimized L/D screw design for LDPE melt flow and HDPE viscosity
- Multi-zone PID heaters with automatic temperature control and insulation
- Automatic screen changer and optional gear-pump for stable pressure
- Die-face hot-cut / water-ring / strand pelletizer options with PLC–HMI
Applications of Plastic Pelletizer Machine for HDPE and LDPE
- Converts HDPE and LDPE scrap into uniform pellets for film blowing, pipe extrusion, blow molding, and injection parts, reducing virgin resin usage and improving sustainability across packaging, construction, and consumer goods manufacturing.
- Supports post-consumer and post-industrial recycling by transforming printed films, carry bags, liners, and raffia into reusable granules that lower production costs and stabilize supply chains for domestic and export markets.
- Generates recycled pellets with controlled MFI and low gel count for smooth downstream processing, improving product consistency, machine uptime, and yields in film, sheet, profile, and molded product lines.
- Integrates with washing, drying, and densifying modules, enabling flexible throughput, automatic filtration, and pelletizing choices to match varying feedstock quality and customer specifications.
Benefits of Plastic Pelletizer Machine for HDPE and LDPE
- Automates feeding, plasticizing, filtration, and cutting for higher throughput and uniform pellets that boost film, pipe, and molding efficiency.
- Reduces energy per kg via optimized screw profile, insulated zones, inverter drives, and stable melt pressure—lowering operating costs and carbon footprint.
- Delivers durable performance with wear-resistant parts, easy-access maintenance, and rugged gearboxes that extend service life and minimize downtime.
- Improves pellet quality—tight size distribution, controlled MFI, and minimal moisture—ensuring smooth extrusion, fewer defects, and less rework.
- Built-in safety guards, emergency stops, and temperature/pressure interlocks enhance operator safety and regulatory compliance.

Plastic Pelletizer Machine for HDPE and LDPE — FAQs
1. What HDPE/LDPE inputs can be pelletized?
+
Washed films, carry bags, liners, shrink wraps, and regrind flakes. Lower moisture and better sorting improve melt stability, pellet quality, and screw–barrel life.
2. What capacity ranges are available?
+
Lines from ~80–150 kg/hr for small units to 500+ kg/hr for high-throughput setups—final output depends on polymer type, filtration fineness, and pelletizing method.
3. Is water-ring or strand pelletizing better for LDPE film?
+
Water-ring offers compact design and consistent round pellets; strand systems allow flexible cut length and easier visual inspection. Choose per product specs and operator preference.
4. How can I improve energy efficiency?
+
Use good insulation, maintain heaters and screens, ensure dry feed, optimize screw speed, and stabilize melt pressure with a gear-pump for lower kWh/kg.
5. Do you provide installation and training?
+
Yes. We handle on-site installation, commissioning, operator training, and after-sales support for fast ramp-up and consistent production.
