What are the differences between injection-molded and extruded WPC outdoor chairs?

When choosing WPC (Wood-Plastic Composite) outdoor chairs, understanding the differences between injection-molded and extruded manufacturing processes is crucial. Injection-molded WPC chairs are created by injecting molten WPC material into a mold, resulting in a seamless, durable, and often more intricate design. This method allows for greater flexibility in shapes and textures but tends to be more expensive due to mold costs.

Extruded WPC chairs, on the other hand, are formed by pushing the material through a die to create continuous profiles, which are then cut and assembled. This process is more cost-effective and efficient for large-scale production but may lack the detailed designs possible with injection molding. Extruded chairs are generally lighter but may have visible seams or joints.

In terms of durability, injection-molded chairs often have higher resistance to weathering and wear due to their uniform density, while extruded chairs may require additional treatments for long-term outdoor use. Both types offer eco-friendly benefits, but your choice depends on budget, design preferences, and intended use.
