From Project Launch to Successful Roll-Off: Wanlong Mould Supports China’s First Mass-Produced Large PC/PUR In-Mold-Coated Component
September 2026
Summary:
On September 22, 2026, China’s first mass-produced large PC/PUR in-mold-coated component successfully rolled off the production line. Jointly advanced by Geely Auto, SABIC and Minth Group, the project represents an important milestone in the industrial application of large-component In-Mold Coating technology. As the precision mold supplier, Zhejiang Wanlong Mold Co., Ltd. contributed its tooling expertise and supported the project’s transition from development and validation to mass production.
On September 22, 2026, a roll-off ceremony was held to mark the successful production of China’s first mass-produced large PC/PUR in-mold-coated component.
The project was jointly advanced by Geely Auto, global diversified chemicals company SABIC and leading automotive component supplier Minth Group.
Following more than two years of collaborative development and technical work, the project has successfully progressed from technology validation to mass-production application.
This achievement marks an important step toward the industrial adoption of In-Mold Coating technology for large automotive exterior components.
Zhejiang Wanlong Mold Co., Ltd. participated in the project as the precision mold supplier, providing tooling support for the stable molding of the large PC/PUR component and the implementation of the In-Mold Coating process. Mr. Du Xiangwei, General Manager of Zhejiang Wanlong Mold Co., Ltd., was invited to attend the roll-off ceremony. Mr. Du An, Project Manager, received the project’s Outstanding Contribution Award in recognition of his contribution to the development of the large PC/PUR In-Mold Coating mold and the successful coordination of the project.
From Project Launch to Mass Production
Since the project’s launch, Geely Auto, SABIC, Minth Group, Wanlong Mould and other value-chain partners have worked closely across material development, product engineering, manufacturing equipment, mold development and molding-process optimization.
The successful roll-off demonstrates that the project has moved beyond preliminary technical assessment and process validation into mass-production practice.
It represents not only a major project milestone, but also the value of close collaboration throughout the automotive manufacturing value chain.
The Mold: A Key Enabler of IMC Mass Production
PC/PUR In-Mold Coating integrates the injection molding of a thermoplastic substrate with the application of a PUR surface coating within the same mold. As a result, the component can achieve a high-quality finished surface directly upon demolding.
Compared with the conventional process of injection molding followed by secondary painting, IMC can reduce downstream painting and material-handling operations. This improves process integration and manufacturing efficiency while helping reduce energy consumption and volatile organic compound emissions associated with conventional automotive painting processes.
As automotive exterior components become larger and more structurally complex, the requirements placed on the mold increase significantly. In addition to high-precision molding, the tooling solution must address uniform cavity-temperature control, reliable sealing, controlled coating flow and consistent performance under mass-production conditions.
·总经理杜祥伟先生与客户技术交流·
Drawing on its experience in the development and manufacturing of large precision automotive injection molds, Wanlong Mould worked closely with the customer on mold engineering, manufacturing and process validation. These efforts provided important tooling support for the smooth progress of the project and the successful production roll-off.
Advancing Green Automotive Manufacturing Through Collaboration
The successful roll-off of this large PC/PUR in-mold-coated component is the result of close collaboration among the automotive OEM, material supplier, component manufacturer, equipment provider and mold supplier.
The achievement further demonstrates the mass-production potential of In-Mold Coating technology for large automotive exterior applications.
It also provides a valuable reference for the automotive exterior industry as it moves toward higher product quality, greater manufacturing efficiency and lower-carbon production. At the same time, the project lays a solid foundation for the wider adoption of IMC technology across additional vehicle programs and application scenarios.
Looking ahead, Zhejiang Wanlong Mold Co., Ltd. will continue to focus on large precision automotive molds and advanced molding technologies. By further strengthening its capabilities in mold engineering, precision manufacturing and process integration, Wanlong Mould will work with global value-chain partners to accelerate the industrial application of In-Mold Coating, paint-free molding and other advanced manufacturing processes.
Wanlong Mould remains committed to providing professional, reliable and integrated automotive tooling solutions for customers worldwide.
