With the rapid expansion of the new energy vehicle (NEV) market, consumer expectations for cabin aesthetics and functionality continue to rise. Traditional painting and electroplating processes are gradually being phased out due to environmental regulations and durability concerns. In-mold decoration (IMD/IML/INS) technology has emerged as a mainstream solution for automotive interior parts manufacturing, offering integrated molding, long-lasting textures, and lightweight advantages. As a professional in-mold injection molding manufacturer based in Ningbo, Zhejiang, Chengdexing leverages the region’s mature mold industry ecosystem to provide high-consistency automotive interior component solutions for multiple NEV manufacturers.
In automotive trim applications, IMD in-mold injection molding enables diverse decorative effects such as brushed metal, carbon fiber, and matte leather grain. The graphics are encapsulated beneath a transparent protective layer, effectively preventing scratches and fading during daily use. This process significantly enhances wear resistance and ease of cleaning for high-touch components like instrument panels, door trims, and gear shift covers. Chengdexing independently manages the entire production workflow—from CAD/CAM mold design and film printing to injection molding—ensuring stable dimensional accuracy and consistent appearance quality for every automotive interior part.
To meet NEV demands for lightweighting and integration, INS in-mold molding technology demonstrates unique value. By thermoforming the film into a three-dimensional shape prior to overmolding, it perfectly conforms to complex curved surfaces such as arched center console panels and irregular air vents, avoiding the stretching distortion common with traditional flat IML on curved geometries. Equipped with imported high-pressure forming machines and precision injection molding equipment, and backed by years of accumulated IMD process know-how, Chengdexing can reliably mass-produce large panels up to 900mm and small functional components as compact as 30mm, accommodating diverse vehicle design requirements.
As one of the earlier manufacturers in the Ningbo region specializing in in-mold insert molding, Chengdexing serves not only OEMs but also Tier-1 suppliers with customized processing services. The company adheres to systematic quality management practices, conducting DFM analysis during the pre-project phase to optimize product structures and mitigate molding risks, while implementing PDCA cycles during mass production to continuously improve yield rates. This approach has earned long-term client trust in the competitive plastic processing market. Looking ahead, as intelligent cabins demand more sophisticated human-machine interfaces, products such as IMD shells and translucent buttons will see broader application. Chengdexing remains committed to advancing this technology to support the upgrade of China’s automotive interior industry.
