What are the friction weld strength benchmarks for WPC outdoor sofa assemblies?

When evaluating the durability and structural integrity of WPC (Wood-Plastic Composite) outdoor sofa assemblies, friction weld strength is a critical benchmark. Friction welding, a common joining method for WPC materials, ensures robust connections that withstand outdoor conditions.

The typical friction weld strength for WPC outdoor sofas ranges between 15-25 MPa (megapascals), depending on material composition and welding parameters. Higher-density WPC formulations often achieve stronger welds, enhancing longevity. Key factors influencing weld strength include temperature, pressure, and welding speed during the process.

For optimal performance, manufacturers should conduct standardized tests, such as tensile or shear strength evaluations, to verify weld integrity. Properly welded WPC outdoor sofas can resist weathering, moisture, and mechanical stress, making them ideal for long-term outdoor use.

By adhering to these benchmarks, producers can ensure their WPC outdoor furniture meets industry standards for safety and durability.
