In recent years, with the widespread adoption of new energy vehicles and smart cockpit concepts, consumers have raised higher expectations for the texture, tactile feel, and visual appeal of automotive interiors. Against this backdrop, INS (In-Mold Navi-Stamping) technology has gradually become a key choice for manufacturing premium automotive interiors due to its ability to achieve complex three-dimensional curved decorations, highly realistic texture effects, and excellent durability. As one of the early enterprises in China to engage in the R&D and application of INS technology, Ningbo Chengdexing Automotive Trim Co., Ltd. leverages its complete manufacturing system and mold development capabilities to continuously provide the automotive industry with high-quality INS interior solutions.
INS technology is an advanced process developed from IML (In-Mold Labeling). Its core lies in first forming pre-printed films into three-dimensional shapes that match the product contour through high-pressure or vacuum thermoforming, and then placing them into injection molds for overmolding. This "form first, inject later" approach enables the product to conform to complex curved surfaces, such as curved dashboard panels and corner areas of door trims, effectively avoiding issues like stretching deformation or pattern distortion that can occur with traditional planar IML in curved applications.
During the development of INS products, Chengdexing utilizes imported high-pressure forming machines and precision injection molding equipment to ensure the accuracy of film forming and the bonding strength during injection molding. Additionally, the company is equipped with inspection and processing tools such as coordinate measuring machines and spark erosion machines to enforce strict quality control over molds and finished products. The entire process, from CAD/CAM mold design to final product delivery, is independently managed by the company, ensuring product consistency and stable delivery.
In terms of materials, Chengdexing selects high-temperature-resistant, UV-resistant PC/PMMA composite films with excellent aging performance, paired with environmentally friendly ink printing. This enables INS products to not only achieve various decorative effects such as metallic brushed finishes, carbon fiber patterns, and wood grains but also maintain color stability and surface gloss over the long term. These characteristics make INS technology widely applicable in mid-to-high-end vehicle models for components like instrument panel trims, air conditioning panels, and center console covers.
With the growing demand for personalized customization in automobiles, the application scenarios for INS technology are expected to expand further. Chengdexing will continue to optimize process parameters, improve film forming efficiency, and enhance injection molding yield rates, providing customers with more design-oriented and functional in-mold decoration products. This effort will support automotive brands in creating differentiated cockpit experiences.
