Founded in July 2024,As China Three-Core Metallic Substrate Suppliers and Wholesale Three-Core Metallic Substrate Factory, Longyou Shuochun New Material Technology Co., Ltd. is a high-tech enterprise specializing in the coating and sales of three-way catalytic converters. It is deeply engaged in the field of new materials.
The company always keeps an eye on the industry frontier, actively learns from and draws on the advanced formulas and mature technologies of domestic and foreign counterparts. Through in-depth research and localization of mainstream formulas, it accurately adjusts the proportion of raw materials such as rare earths, precious metals and non-precious metals, so as to ensure that the coated carriers produced have stable catalytic activity and reliable performance.
The company's products cover a variety of specifications and models, and its products and technologies are applicable to automobiles, motorcycles, general-purpose engines, construction machinery, marine power, generator sets, agricultural machinery and other fields.
In the future, the company will continue to learn advanced industry experience, optimize production and services, and contribute to the realization of carbon peaking and carbon neutrality goals in China and around the world.
The three-core metal substrate adopts a multi-channel, parallel, three-layer honeycomb structural design, in which each core module independently handles a portion of the exhaust flow distribution and catalytic reaction. This configuration ensures uniform gas flow distribution and efficient heat transfer while maintaining low backpressure, thereby significantly improving catalyst utilization and overall conversion efficiency. The three-core layout provides distinct advantages in multi-stage catalytic systems for large-displacement engines or heavy-duty diesel vehicles: the main channel facilitates CO/HC oxidation reactions, while the secondary or downstream channels enable NO₂ generation or selective reduction functions. The use of Fe-Cr-Al alloy materials offers excellent high-temperature stability, and the precision brazing process ensures the mechanical integrity and vibration resistance of the multi-core structure. The three-core metal substrate is commonly applied in dual-stage catalytic systems, DOC+DPF integrated modules, and multiphase reaction systems of high-performance passenger vehicles, representing an innovative carrier solution that balances emission efficiency with mechanical strength.
