Evolution! Large-scale IMC In-Mold Coating Project Launched:
Wanlong Mould Participating as Core Supplier
partnering with Geely Auto and Minth Group to drive the transition from technical assessment to mass production via high-precision tooling solution
On January 28, 2026, Mr. Du Xiangwei, General Manager of Zhejiang Wanlong Mold Co., Ltd., was invited to the Geely Research Institute for the strategic project report and launch ceremony of the IMC (In-Mold Coating) process. This project is a collaboration between global automaker Geely, chemical leader SABIC, and top-tier supplier Minth Group.
The event marks the large-scale exterior automotive components using advanced IMC technology have successfully passed technical assessments, with mass production and market release expected shortly.

During the meeting, Geely outlined the project’s industrial background, core objectives, and current progress, establishing a clear roadmap for implementation.
The launch also brought together key partners across the supply chain, including injection molding leader KraussMaffei, precision mold specialist Zhejiang Wanlong, and PUR suppliers REPU and Liming Chemical. Several IMC samples were showcased, demonstrating the massive market potential and technical value of this integrated molding process.

Technological Advantages of IMC
Efficiency & Cost Reduction
Traditional painting involves 8 to 10 tedious steps (molding, pretreatment, priming, coating, curing, etc.). IMC integrates these into 1 or 2 core steps. This allows for rapid color changes and eliminates the need for complex exhaust treatment equipment, significantly lowering production costs as the technology scales.
Eco-Friendly & Low Carbon
Traditional painting is a major source of Volatile Organic Compounds (VOCs). IMC uses solvent-free or low-solvent materials, reducing VOC emissions by 80% to 90%. With coating utilization rates near 100%, it perfectly aligns with the industry's shift toward green, low-carbon manufacturing.
Superior Aesthetics & Functionality
By optimizing mold temperature control and flow channels, the IMC process produces a smooth, uniform finish free of "orange peel" or air bubbles. When paired with specialized materials from partners like SABIC and Covestro, components gain scratch self-healing properties and can feature nano-scale textures or complex structural colors.
Wide Compatibility
The process is highly versatile, suitable for bumpers, grilles, and roof trims, as well as interior dashboards and center consoles for both passenger and commercial vehicles.

The rise of IMC technology is a critical step toward intelligent and sustainable automotive manufacturing. As leaders like Geely, SABIC, and Minth continue to collaborate with supply chain partners, a complete ecosystem—from material innovation to mold design—is taking shape.

With the drive toward carbon neutrality and consumption upgrades, IMC is set to become a standard in automotive manufacturing. Beyond the automotive sector, this advanced surface treatment technology is expected to expand into home appliances, consumer electronics, and high-end furniture.

On March 19, 2026, the domestic industry’s first large-scale IMC (In-Mold Coating) automotive exterior component successfully rolled off the production line in Jiaxing, China. As a key partner and precision mold supplier, Wanlong Mould was deeply involved in the R&D of this milestone project for Li Auto. The Wanlong team successfully overcame deformation control challenges for the 1.4m x 1.2m extra-large mold and pioneered an "all-scenario" sealing solution. By maintaining PUR coating thickness tolerances within ±0.1mm, Wanlong helped Li Auto achieve a critical "0-to-1" breakthrough in green manufacturing for exterior parts.
