Closed mold operation stands out as an eco-friendly manufacturing method with extremely low volatile organic compound emissions, effectively reducing environmental impact and ensuring a safer working environment. This process is particularly well-suited for RTM resin, as the closed structure enables RTM resin to fully infiltrate the fiber reinforcement under controlled pressure, resulting in consistent and high-quality impregnation. Products manufactured this way feature smooth, aesthetically pleasing surfaces on both sides without post-processing, along with excellent dimensional stability and high precision. With reliable process control and stable output, this closed mold technique is highly efficient and cost-effective, making it an ideal choice for medium-batch production of composite components across various industrial applications.
