Q: What materials can Haorui pelletizing machines process?
A: Our machines are highly adaptable and process various recycled plastics, including PP, PE (HDPE/LDPE/LLDPE), PET, and ABS. Whether you are recycling washed flakes, fluffy films, or clean industrial scrap, we provide customized screw designs to ensure a stable output.
Q: Should I choose a single-stage or a double-stage pelletizing system?
A: We recommend double-stage (two-stage) systems for post-consumer waste with heavy impurities or moisture. This design ensures more stable operation, produces cleaner and denser pellets, and provides superior multi-stage degassing compared to single-stage models.
Q: What is the difference between Strand and Underwater pelletizers?
A:Strand Pelletizing: Best for rigid plastics (HDPE/PP) and startups; it is simpler to maintain and has a lower upfront cost.
Underwater Pelletizing: Ideal for high-volume mass production and "challenging" materials like TPU or TPE. It offers high automation, saves space, and produces perfectly uniform, spherical pellets.
Q: How does the system handle trapped gases and moisture?
A: Our lines feature intensive vacuum degassing sections to remove volatiles, air, and residual moisture. This prevents bubbling and odors, ensuring the final pellets are transparent, solid, and of high market value.
Q: What ensures the durability of Haorui's pelletizing equipment?
A: We use high-grade 38CrMoAl nitrided steel for our screws and heavy-duty hard-gear reducers to resist wear. This design, combined with SIEMENS motors, significantly extends the machine's lifespan and reduces maintenance costs.
Q: Why choose Haorui over other manufacturers?
A: Established in 1992, we are a Top 3 Chinese manufacturer with 30+ years of experience. Uniquely, we operate our own recycling factory in Nigeria; this "operator" perspective allows us to design machines that are easier to disassemble, clean, and maintain in real-world conditions.
Q: What kind of after-sales support and lead time do you provide?
A: We offer a 1-year warranty and lifetime technical support. We provide turnkey solutions, including free CAD factory layouts and on-site installation and training. Standard production time is 30 to 70 days as we manufacture everything in our own facility.
