What design limitations exist when using WPC for outdoor chair manufacturing?

Wood-Plastic Composite (WPC) is a popular material for outdoor furniture due to its eco-friendly nature and low maintenance. However, when it comes to manufacturing outdoor chairs, WPC presents several design limitations.

1. Limited Aesthetic Flexibility: WPC often mimics wood but lacks the natural grain and texture, limiting design creativity. Custom colors and finishes are harder to achieve compared to traditional materials.

2. Durability Concerns: While WPC is resistant to rot and insects, prolonged exposure to UV rays and extreme weather can cause fading, warping, or cracking over time.

3. Weight and Strength: WPC is heavier than pure plastic but may not offer the same structural strength as solid wood or metal, restricting intricate or load-bearing designs.

4. Moisture Absorption: Despite being water-resistant, WPC can absorb moisture in humid climates, leading to swelling or mold growth if not properly treated.

5. Cost vs. Performance: High-quality WPC can be expensive, and cheaper variants may compromise on longevity, making it a less cost-effective option for long-term outdoor use.

Understanding these limitations helps manufacturers balance aesthetics, functionality, and durability when designing WPC outdoor chairs.
