Backed by a factory-direct, end-to-end production model, it offers one-stop closed-loop services—from measurement and design to manufacturing, installation, and after-sales support—utilizing high-precision CNC cutting and Nanxin PUR edge-banding technology. The product combines eco-friendly, moisture-resistant, durable, and stable qualities, and can also be custom-made to meet specific school project requirements, making it suitable for various educational settings and training institutions.
Core Manufacturing Process: CNC Cutting
The board processing for these desks and chairs employs high-precision CNC-driven cutting equipment. At its core, the process relies on “digital programming plus three-axis coordinated motion” to achieve precise material cutting, ensuring clear and controllable workflows that safeguard dimensional accuracy and processing quality from the outset.
Breakdown of the Core CNC Cutting Process
1. Design-to-Coding Stage: First, CAD/CAM software is used to import the design drawings of the desks and chairs. Intelligent nesting software automatically optimizes the layout to maximize material utilization, ultimately generating G-code machining instructions readable by the equipment, ensuring every cut adheres to design specifications.
2. CNC Drive Stage: After reading the G-code, the CNC system outputs pulse signals to drive the X/Y/Z axis servo motors, guiding the cutting tool along pre-set paths for precise three-dimensional movement, achieving highly accurate positioning and cutting of the boards.
3. Processing Execution Stage: A vacuum suction table firmly secures the raw materials, preventing any shifting or misalignment during cutting. High-speed rotating tools, combined with feed motions, enable simultaneous completion of multiple operations such as cutting, slotting, and drilling, significantly boosting both efficiency and precision.
Technologies Ensuring CNC Cutting Precision
• Servo Drive System: Positioning accuracy reaches ±0.02mm, with repeatable, precise movements that never deviate, guaranteeing exact dimensions for every processed component.
• Linear Guides + Ball Screws: Ensure smooth tool motion, minimize errors during cutting, and enhance the flatness of the finished boards.
• Automatic Tool-Changing System: Allows seamless switching between different tools for various processes without manual intervention, improving efficiency while eliminating human error associated with tool changes.
• Vacuum Suction Table: Firmly holds the boards in place during cutting, preventing misalignment and ensuring processing accuracy and product quality.
Advantages of CNC Cutting Technology
Compared to traditional manual cutting methods, CNC cutting keeps overall errors within 0.1mm—far surpassing manual precision. Processing efficiency is 5–8 times higher than conventional techniques; in an 8-hour shift, up to 200 boards can be processed, quickly meeting the supply demands of large-scale school projects. Intelligent nesting boosts material utilization to over 90%, effectively reducing material waste and production costs.
Core Manufacturing Process: Nanxin PUR Edge-Banding
The edges of the desk and chair boards are sealed using Nanxin’s PUR edge-banding technology, executed with specialized Nanxin edge-banding equipment. The core principle involves using “moisture-reactive polyurethane hot-melt adhesive” for chemical cross-linking bonding. Compared to traditional edge-banding methods, this approach delivers superior stability, significantly enhancing the durability and aesthetic appeal of the desks and chairs.
Breakdown of the Core Principles Behind Nanxin PUR Edge-Banding
1. Pre-Melting the Adhesive: At room temperature, PUR adhesive exists as a solid. The equipment heats it to 130–150°C, turning it into a liquid state. It is then evenly applied to the board edges via a dedicated glue tank, ensuring uniform coating and strong adhesion.
2. Cross-Linking and Curing Reaction: Once the liquid PUR adhesive comes into contact with air, the isocyanate groups within react with atmospheric moisture, gradually forming a three-dimensional network of cross-linked polymers that tightly bond the board to the edge banding strip.
3. Irreversible Bonding: After the reaction completes, the adhesive fully cures, forming covalent bonds that cannot be reversed. Even reheating will not soften the bond, resulting in an adhesive strength 2–3 times greater than traditional EVA glue, ensuring long-term stability and resistance to peeling.
Nanxin PUR Edge-Banding Standard Operating Procedure
• Preparing the Boards: Sand and clean the board edges to remove dust and oil, ensuring a smooth, clean bonding surface as a foundation for subsequent gluing.
• Applying the Glue: The equipment precisely controls the amount of glue, requiring only about 150g per square meter—far less than traditional EVA glue—saving costs while avoiding issues caused by excessive glue application.
• Pressing and Bonding: After applying the edge banding strip, multiple sets of pressure rollers gradually increase pressure, ensuring complete adhesion without air bubbles and strengthening the bond.
• Post-Treatment: Through processes like trimming, edging, scraping, and polishing, excess edge banding is removed, leaving the board edges smooth, neat, and free of burrs or protrusions.
• Final Curing: Allow the bonded edges to sit at room temperature for 24–48 hours, letting the cross-linking reaction finish completely before reaching final bonding strength, ensuring long-term durability without peeling.
Key Advantages of Nanxin PUR Edge-Banding
• Excellent Weather Resistance: Maintains stability across a wide temperature range from -30°C to 120°C, resisting softening or deformation—even in classrooms with underfloor heating or environments subject to significant temperature fluctuations.
• Extremely Fine Glue Lines: With widths of only 0.03–0.05mm, the glue lines are virtually invisible, greatly enhancing the overall aesthetics of the desks and chairs and meeting schools’ requirements for a clean, polished look.
• Waterproof and Eco-Friendly: Forms a dense waterproof layer upon curing, effectively preventing moisture penetration and board deformation; meanwhile, the PUR adhesive itself is formaldehyde-free, complying with ENF environmental standards to ensure student health and safety.
• Long-Lasting Durability: With stable bonding strength, even after seven years of use in high-humidity conditions, the edges remain intact without peeling or mold, significantly extending the lifespan of the desks and chairs and reducing schools’ furniture procurement and maintenance costs.
