Benefits of technology

This patented innovation relates to an improved method or material that combines fibers together to make stronger plastic products more durably without adding extra weight compared to traditional methods like metal casting. It also allows for quick cooling during manufacturing while maintaining its quality level. Additionally, it provides good mechanical properties such as tensility at room temperatures, flexibility under tension, shock resistence, weather proofness, etc., along with excellent thermal conductivity and insulation characteristics. Overall, this new product design improves efficiency and reduces costs over current options.

Problems solved by technology

This patented technical problem addressed in this patents relates to making strong fibers that can be easily injected into plastic materials without losing their shape or causing damage during manufacturing processes like injection molds. These fibers should also provide good durability against weather conditions while maintaining excellent performance over time under harsh environments.
