✅ High-Capacity Design - The main extruder has a capacity of 380-420 kg/h, meeting the needs of large-scale construction materials.

✅ Intelligent Control System - Fully automatic control, achieving integrated operation of extrusion, molding, and cutting.

Technical Parameters and Configuration

Solving Key Technical Challenges in Corrugated Sheet Production

High-Efficiency Plasticization with Conical Twin-Screw Screw

Utilizing a φ80-φ156 conical twin-screw design, the progressive compression ratio perfectly matches the characteristics of PVC powder. The screw is made of alloy steel with nitriding treatment, increasing wear resistance by 40% and ensuring stability during long-term continuous production. A high torque output of 16000 N.m easily handles highly filled PVC formulations.

PVC/ASA Dual-Material Co-extrusion Technology

The main extruder processes the PVC base layer, while the auxiliary extruder precisely measures the ASA top layer material. A perfect interlayer bonding is achieved through a YJM1300 distributor. The ASA layer provides excellent weather resistance and UV resistance, while the PVC base layer ensures product strength and cost advantages—one-time molding, dual functionality.

Precise Replication of Complex Wave Structures

An 800mm long shaping die, combined with a vacuum adsorption and water cooling system, ensures precise wave structure forming and uniform cooling. The traction system uses styrene-butadiene rubber rollers, providing a maximum traction force of 20KN, ensuring the product does not deform or stretch during traction.

Integrated Intelligent Control

The entire line uses a centralized control system, achieving synchronized speeds of the main and auxiliary machines, precise temperature control, and automatic length cutting. The user interface is intuitive and user-friendly, with real-time monitoring of key parameters and automatic fault alarms, significantly reducing the technical requirements for operators.

Frequently Asked Questions

Q1: Can this production line produce other specifications of corrugated sheets? 

Yes. By changing the molding die and adjusting the process parameters, corrugated sheets with different waveforms and widths (typically in the range of 600-1300mm) can be produced. We offer custom die-making services.

Q2: What is the function of the ASA layer? Can it be omitted?

The ASA layer primarily provides weather resistance, UV resistance, and color stability. If the product is intended for indoor or short-term use, the ASA layer can be omitted, and single-layer PVC can be used. However, for outdoor construction, ASA co-extrusion is strongly recommended to extend its service life.

Q3: Are you a machinery factory or a trading company?

A: We have our own factory, which means we can strictly guarantee product quality and delivery time, and we don't charge middlemen.

Q4: If we have very specific requirements for the production line, can you help me with the design?

A: We provide optimized equipment configurations based on your specific product specifications and production capacity requirements. The operating direction and exterior paint color of the equipment can be customized according to your requirements. Experienced mechanical designers provide customized designs.

Q5: Do you provide equipment testing services?

A: Yes, we provide on-machine testing services. An additional testing fee will be charged based on testing costs (electricity, labor, etc.).

Q6: How do you ensure the machine runs well in the factory?

A: If you need assistance with installation and staff training, we can send engineers overseas to solve all problems. Commissioning normally takes 7-8 days, excluding travel time. Overseas customers are responsible for the round-trip airfare, wages, accommodation, and safety of the commissioning personnel.

Q7: How can I effectively get a quote?

A: Please click the "Send Inquiry" or "Contact Seller" button at the bottom of the page. Leave a message describing the details of your final product (preferably with pictures and dimension drawings), production requirements, etc. We will reply to your inquiry within 12 hours.

Q8: How can we visit your company and machines?

A: Our factory is located in Jiaozhou City, Qingdao, Shandong Province, China, with convenient transportation, 18 kilometers from Qingdao Jiaodong International Airport.
