PVC Corner Bead Extrusion Line
Deerma Machine is a leading manufacturer of PVC corner beads extrusion making machines, offering advanced production lines designed for high-efficiency manufacturing of interior and exterior wall corner guards.
What is a PVC Corner Beads Extrusion Making Machine?
A PVC corner beads extrusion making machine is specialized industrial equipment used to produce PVC corner beads and arch beads that protect the corner edges formed by gypsum boards. The bead edge enables an aesthetic finish of the putty, while providing better mechanical protection compared to traditional materials. The risk of damage to PVC beads during handling and transportation is significantly lower, making them the preferred choice for modern construction projects.
Deerma Machine has developed various PVC corner bead production lines with double cavity, four cavity, and six cavity configurations, saving time and effort while dramatically increasing extrusion capacity.
Applications of PVC Corner Beads：
PVC corner beads produced by Deerma Machine’s extrusion lines are widely used for:
• Interior and exterior wall corner protection
• Gypsum board edge finishing
• Corner crack prevention
• Construction speed acceleration
• Wall corner aesthetic maintenance
Key Benefits of PVC Corner Beads:
• Eco-friendly PVC materials — strong, tough, corrosion-resistant, and impact-resistant
• Softened edges and corners — reduce damage and better fit wall surfaces
• Enhanced impact resistance — protects wall corners from daily wear
• Flat, burr-free punched holes — ensure better bonding with putty powder
• Fiberglass mesh integration — solves unevenness and impact damage issues in insulation systems

Advantages of PVC Corner Bead Extrusion Line:
High Efficiency & Stability
The production line delivers robust extrusion performance, ensuring thorough plasticization of materials. This effectively eliminates internal bubbles and surface impurities, resulting in corner guards with a smooth, flawless finish and consistent structural integrity.
Flexible Customization
Equipped with high-precision molding dies, the system allows for quick adjustments to accommodate various corner guard profiles and specifications. This flexibility enables manufacturers to respond swiftly to diverse market requirements and custom orders.
Multi-Cavity Design
To maximize throughput, the line supports double, four, or six-cavity die configurations. This scalable design significantly increases output volume, allowing production capacity to be matched precisely with business demands.
Automatic Operation
The integration of automated controls minimizes manual intervention, streamlining the production cycle from extrusion to cutting. This not only reduces labor costs but also guarantees superior product consistency and repeatability.
Energy Efficient
Featuring ABB frequency control systems, the equipment optimizes motor power consumption based on real-time load. This intelligent energy management leads to substantially lower electricity usage without compromising performance.
