Yongte Successfully Delivers Custom 92/188 Conical Twin-Screw Extruder for PVC WPC Foam Board Production

Yongte, a leading manufacturer of high-end plastic extrusion equipment with over 20 years of industry expertise, is pleased to announce the successful completion and delivery of a custom-built 92/188 conical twin-screw extruder for a domestic client. The machine is specifically engineered for the production of PVC wood-plastic composite (WPC) foam boards and has already received strong praise from the customer for its outstanding quality and reliable performance.

Tailored Engineering for PVC WPC Foam Board

The 92/188 extruder was designed and manufactured to meet the customer's precise production requirements. At its core is a 92 mm diameter conical twin-screw system, optimized for uniform plasticization and efficient mixing of PVC wood-plastic composite formulations. The conical screw geometry ensures excellent shear control and material compression, making it ideally suited for foam board extrusion where consistent density and surface finish are critical.

The extruder is mounted on an integrated heavy-duty base frame, providing exceptional structural rigidity and vibration damping during high-load operation. This robust foundation contributes directly to the machine's long-term precision and reliability.

High-Performance Drive and Transmission

To deliver both power and energy efficiency, the extruder is equipped with a 110 kW permanent magnet servo motor. Compared with conventional drive systems, the servo motor offers precise speed control, rapid response, and significantly reduced energy consumption — a key advantage for customers seeking to lower operational costs while maintaining high output.

Power is transmitted through a high-torque, high-strength hardened-gear reducer, engineered for durability under continuous heavy-load operation. The hardened gear surfaces ensure minimal wear, extended service life, and stable, quiet performance over long production runs. The gearbox also delivers excellent mixing and self-cleaning performance, preventing material buildup and ensuring consistent melt quality throughout the extrusion process.

Intelligent Control with Siemens PLC

The machine features an intelligent electrical control system built around a Siemens PLC, providing the customer with a highly reliable, user-friendly operation interface. Key production parameters — including temperature profiles, screw speed, feed rate, and extrusion pressure — are monitored and adjusted in real time, ensuring process consistency and reducing the risk of production defects.

The control system is housed in an integrated electrical cabinet with a split-door design, paired with a separated HMI console that gives operators a clean, ergonomic workspace away from the heat and vibration of the main machine. The cabinet incorporates an independent forced cooling system to maintain optimal internal temperatures, along with interlock safety protection to safeguard both personnel and equipment. The entire enclosure is dust-proof, specifically engineered to withstand the demanding environment of a plastic production workshop.

Versatile Material Compatibility

Beyond PVC WPC foam board production, the 92/188 conical twin-screw extruder demonstrates wide material compatibility, making it suitable for a diverse range of applications including filler masterbatch production, plastic modification, and recycling pelletizing. This versatility allows customers to maximize the utilization of their investment across multiple product lines and material types.

Customer Feedback

Following installation and commissioning, the customer reported that the extruder delivers stable continuous running, high production output, and low energy consumption — fully meeting and exceeding their expectations. The machine's build quality, ease of maintenance, and smoothness of its operation were specifically highlighted as standout features.

"We are committed to delivering extrusion solutions that combine precision engineering with real operational value," said a spokesperson for Yongte. "This 92/188 project is another example of our ability to tailor equipment to each customer's unique application, and we are delighted that the results have been so well received."
