Corrugated cardboard single facer making machine

High-Performance SF-280A Single Facer Machine for B/E Flute Corrugated Cardboard Production

The SF-280A single facer machine is a robust, precision-engineered solution designed for efficient and consistent manufacturing of B/E flute corrugated cardboard. Ideal for medium-scale packaging operations worldwide, this industrial-grade equipment combines advanced materials, ergonomic design, and reliable performance to deliver high-quality board production with minimal downtime. Whether you're producing shipping containers, retail packaging, or custom cartons, the SF-280A ensures durability, energy efficiency, and operational safety across global markets.

Key features include a hood-type suction system integrated into a compact control cabinet, which houses powerful airflow management components such as a 7.5kW fan and silencer technology—ensuring quiet operation while maintaining optimal vacuum pressure. The unit’s cast iron wall panels (130mm thick) provide exceptional rigidity and vibration damping, contributing to long-term structural integrity under continuous use. All critical rollers are manufactured from premium alloys: the corrugating roller (¢280mm) uses 48CrMo alloy steel with surface hardness exceeding HRC 58 after quenching and polishing, while the pressure roller (¢292mm) benefits from chrome-plated grinding for uniform contact and wear resistance. High-temperature bearings from Wafangdian enhance reliability in demanding environments.

The glue application system employs pneumatic-controlled rubber rollers (¢216mm), featuring pit-patterned hard chrome plating that ensures even adhesive distribution without waste. The preheater cylinder (¢320mm seamless steel pipe from Tiangang) delivers precise thermal regulation within a 160–200°C range, enabling fast bonding and improved board strength. With a maximum working speed of 50 meters per minute and a 1600mm web width, the SF-280A supports versatile production runs tailored to various corrugation profiles, including B-flute and E-flute configurations. Its modular construction allows flexible installation orientation (left or right), making it adaptable to diverse factory layouts.

This single facer machine excels in applications requiring durable, cost-effective packaging solutions—such as e-commerce fulfillment centers, food and beverage logistics, electronics distribution, and consumer goods manufacturers. It's particularly suited for businesses seeking to scale up production capacity without compromising on quality or consistency. The electric heating system (380V/50Hz) provides stable temperature control, reducing energy consumption compared to gas-based alternatives, while the S1 continuous-duty motors (7.5kW each for main drive and suction) ensure uninterrupted operation during peak hours.

Users consistently praise its ease of maintenance, thanks to fully enclosed operating sides and clearly labeled components. Operators report fewer mechanical failures over time due to the use of certified raw materials like Zhongyuan Special Steel for rollers and precision-machined parts throughout. Many buyers highlight how the machine’s built-in limit switches and buffer devices prevent accidental damage during roll changes or startup procedures—a key advantage in automated lines.

Common inquiries often revolve around setup complexity and compatibility with existing production lines. While initial commissioning may require technical guidance, most users find the intuitive controls and clear documentation simplify integration. Another frequent question concerns material compatibility; the SF-280A performs reliably with both kraft linerboard and recycled pulp stock, provided the moisture content remains within recommended parameters. Maintenance intervals are typically every 500–700 operating hours, depending on usage intensity, with routine checks focusing on roller alignment, belt tension, and air filter cleanliness.
