Product Application

WPC granules produced by Yongte's WPC Pelletizing Machine demonstrate excellent plastification, consistent quality, and high output. These granules boast superior mechanical properties, such as high impact resistance and tensile strength, making them perfect for creating durable WPC products like decking, fencing, and furniture. The uniform particle size and density of the pellets ensure seamless processing in downstream extrusion or injection molding machinery, minimizing production waste and enhancing overall efficiency. Furthermore, the environmentally friendly composition of the granules, which combines recycled plastics with renewable wood fibers, aligns with global sustainability trends, aiding manufacturers in meeting environmental regulations and consumer demand for eco-friendly materials.

Why choose Yongte WPC Pelletizing Machine?

1, We equip servo motors for precise operational control and energy efficiency, reducing power consumption by up to 20% compared to conventional motor systems while ensuring consistent production accuracy.

The integration of servo motors in the Yongte WPC Granulator enables precise, real-time control over the granulation process. This precision guarantees consistent particle size distribution—a critical factor for manufacturing high-quality WPC granules with uniform physical properties. Moreover, the servo motors’ high responsiveness allows for rapid, dynamic adjustments during production, minimizing downtime and optimizing overall system efficiency and reliability. Notably, the servo motor system reduces power consumption by approximately 15-20% compared to traditional motor configurations, enhancing energy efficiency while maintaining production precision.

2, We equip W4 screw components for enhanced durability and extended service life, ensuring stable performance even under continuous high-load operation. The high-strength W4 screw material resists wear and tear, reducing maintenance frequency and prolonging the machine’s operational lifespan.

The primary carbide phase in WR4 material is vanadium carbide (VC), which exhibits an ultra-high microhardness of HV2600—endowing the material with exceptional hardness and superior wear resistance. The carbides in WR4 are uniformly dispersed in a spherical or near-spherical morphology, a structure that significantly enhances impact toughness by minimizing stress concentration points. Furthermore, heat treatment tests reveal that WR4 demonstrates minimal dimensional deformation during quenching (even under identical process conditions) and achieves highly uniform post-quenching hardness. Its metallographic structure is characterized by fine-grained martensite, which contributes to excellent anti-spalling performance and long-term wear resistance. Engineered specifically for high-wear applications—particularly in high-filler polymer processing fields—WR4 enables our WPC Pelletizing Machine to produce WPC pellets with a wood content of up to 70% while maintaining structural integrity and process stability.

3, "8"-shaped barrel made of 101 Alloy material

The Yongte barrel design is employed for its exceptional heat resistance and corrosion resistance, significantly boosting the efficiency and stability of the granulation process. The integration of the "8"-shaped barrel and 101 Alloy material guarantees consistent product quality while minimizing the need for frequent maintenance, thereby further enhancing the system's operational reliability.

4, highly automated system

The highly automated system integrated into the granulation process significantly reduces manual intervention, thereby minimizing human errors and enhancing operational precision. It features advanced control algorithms that monitor and adjust process parameters in real-time, ensuring optimal conditions for granule formation. This automation not only streamlines production but also enables continuous monitoring and data logging, facilitating rigorous quality control and full traceability of production batches. Additionally, the system is equipped with an intuitive user interface and remote access capabilities, allowing operators to manage and troubleshoot the process from any location, further improving overall operational efficiency and responsiveness.

5, High-quality electric control system

Equipped with top-tier branded electrical components—including ABB inverters, Siemens contactors, Omron temperature controllers, and a Siemens PLC control system—our electric control system ensures precise and stable operation of the entire automated production line. The system integrates advanced control algorithms and high-precision sensors to accurately regulate key production parameters such as speed, pressure, and temperature in real time. This meticulous control not only guarantees consistent product quality but also minimizes the occurrence of defects. Additionally, the system features an intelligent self-diagnostic function that rapidly detects potential issues and alerts operators, enabling timely maintenance and significantly reducing unplanned downtime.
