Kaihua introduces high-tech, innovative molds and process technologies to provide guarantees for low-cost and high-efficiency parts manufacturing. From preliminary research, to engineering design, to interactive design, through structural case analysis, lightweight technical reserves, ergonomics research and development, and the practice of replacing steel with plastic, the structural design and appearance design are perfectly unified. The innovative application of micro-foaming injection molding technology in door panels, tailgates, dashboard frames and other products can effectively shorten the molding cycle, prevent product surface shrinkage, and reduce product weight efficiently. Through the research and development of multi-color high-gloss injection molding technology, that is, two-color, three-color injection molding, and high-gloss two-color injection molding, it can effectively reduce costs and improve product appearance in terms of ventilation panels, engine room.
