IPG Pelletizing Machine for Plastic: Efficient Solutions for Polymer Processing
The requirement for high-efficiency and precise pelletizing systems within the plastic industry keeps rising, especially as manufacturers focus on quality control, sustainability, and cost-efficiency. Among the leaders in this space is IPG (International Process Group), offering advanced pelletizing machines for parts. IPG’s pelletizing technology delivers consistent results, enabling smooth downstream processing and improved material handling for a wide range of thermoplastics.
🔍 What is an IPG Pelletizing Machine?
An plastic pellet machine is a specialized item of equipment used to transform molten plastic into uniform pellets or granules. These pellets are the preferred form for transporting, storing, and feeding parts into molding or extrusion machines. IPG designs both strand pelletizers and underwater pelletizing systems, according to the type of plastic, throughput, and cooling requirements.
🏭 Applications of IPG Plastic Pelletizing Machines
IPG pelletizing systems are utilized in various polymer and plastic recycling processes including:
Polyethylene (PE) – LDPE, HDPE
Polypropylene (PP)
Polystyrene (PS)
Polyamide (Nylon, PA)
PET and also other polyesters
Bioplastics and biodegradable polymers
Thermoplastic elastomers (TPE, TPU)
Recycled plastic compounds (post-industrial & post-consumer)
⚙️ Types of IPG Pelletizing Technologies
1. Strand Pelletizing Systems
Plastic melt is extruded by way of a die into strands
Strands are cooled inside a water bath, dried, and cut into pellets by rotating knives
Suitable for rigid, semi-crystalline plastics and masterbatches
2. Underwater Pelletizing Systems (UWP)
Molten plastic exits the die straight into a water-filled chamber
Rotating knives cut the strands under water
Pellets are then separated, dried, and conveyed
Ideal for high-throughput, sticky, or soft polymers
3. Water Ring Pelletizers
Designed for softer thermoplastics with low output
Simpler than underwater systems, by using a rotating water ring to cool down the and transport pellets
