In-mold decoration technologies—such as IMD (In-Mold Decoration), IML (In-Mold Labeling), and INS (In-Mold Foil Stamping)—represent highly integrated advanced manufacturing processes. Their successful implementation relies not only on injection molding itself but also on the precise coordination of multiple upstream stages, including mold development, film printing, and thermoforming. Since its inception, Ningbo Chengdexing Automotive Trim Co., Ltd. has consistently focused on building a comprehensive, end-to-end manufacturing system covering “design – mold making – printing – thermoforming – injection molding,” delivering stable and reliable IMD/IML/INS products to customers in the automotive, home appliance, medical, and other industries.
Molds form the core foundation of IMD/IML/INS processes. Strategically located in Ninghai, Ningbo—a renowned hub for China’s mold industry—Chengdexing benefits from exceptional local industrial resources and deep technical expertise. The company is equipped with high-precision machinery, including CNC machining centers, EDM (electrical discharge machining) equipment, and wire-cut machines, enabling in-house design and fabrication of complex injection molds. Particularly for INS applications, molds must precisely match the contours of three-dimensionally thermoformed films, demanding extremely tight dimensional tolerances. To ensure mold accuracy, Chengdexing employs coordinate measuring machines (CMMs) for full-process quality inspection.
In the film preparation stage, the company uses flatbed screen printers to achieve high-resolution decorative patterns and selects film materials—such as PET, PC, or PMMA—based on product requirements, balancing both aesthetics and functionality. Subsequently, imported high-pressure or vacuum thermoforming machines transform these flat films into precise 3D shapes, ready for the final injection molding step. The finished components are then integrally molded in precision injection molding machines.
This vertically integrated, in-house manufacturing model not only enhances product consistency but also significantly shortens development lead times. Customers need only provide their design specifications; Chengdexing handles everything from concept validation and mold development to mass production under a seamless one-stop service model. This approach proves especially advantageous for urgent projects or small-batch custom orders.
Looking ahead, as trends in smart manufacturing and sustainable production continue to evolve, in-mold decoration technologies will find broader applications across more industries. Chengdexing remains committed to strengthening its technical foundation and optimizing process workflows, delivering professional, reliable, and efficient IMD, IML, and INS solutions to customers worldwide—and driving high-quality advancement across the industry.
