What are the differences between extruded and molded PVC outdoor seating components?

When choosing PVC outdoor seating components, understanding the differences between extruded and molded PVC is crucial. Extruded PVC involves forcing molten PVC through a die to create continuous shapes, resulting in uniform profiles with high strength and weather resistance. This method is ideal for long, straight components like chair legs or rails.

Molded PVC, on the other hand, is formed by injecting molten PVC into a mold cavity, allowing for complex shapes and intricate designs. This process is better suited for curved or detailed parts, such as armrests or decorative elements. While molded PVC offers more design flexibility, extruded PVC typically provides greater structural integrity and longevity.

Cost-wise, extrusion is generally more economical for high-volume production of simple shapes, whereas molding incurs higher tooling costs but excels in custom or ornate designs. Both methods yield UV-resistant and low-maintenance products, but extruded PVC often outperforms in heavy-duty applications due to its denser molecular structure.

For outdoor furniture manufacturers, the choice depends on design requirements, budget, and performance expectations. Extruded PVC suits functional, load-bearing parts, while molded PVC enables aesthetic versatility without sacrificing durability.
