Milestones
A Decade of Building Trust
From a single production line to an integrated manufacturing system, each milestone represents a capability built in-house.
Company Founded in Shandong
YIFENG CAT started with ceramic honeycomb substrate production, serving domestic emission control and replacement converter demand. The early focus was process stability, dimensional accuracy, extrusion consistency and firing control for different substrate specifications.
First International Export
The first export orders helped the team build a more complete understanding of overseas buyer requirements, including product documentation, packaging protection, shipping coordination, customs documents and communication before shipment.
In-House Catalyst Coating Capability
The company began building internal catalyst coating capability to support more complete emission control solutions. This step connected substrate manufacturing with coating process control, helping the factory reduce dependence on external coating resources.
Quality System and Process Control Improved
Quality management became more systematic across incoming material inspection, production records, process checkpoints, finished product inspection and shipment review. The team placed more emphasis on traceability and repeatable standards.
Facility Expansion and Capacity Upgrade
Production space and equipment capacity were expanded to support growing demand for substrates, catalytic converter assemblies and related components. The factory improved workshop layout, warehouse handling and internal testing support.
30+ Export Markets and Broader Product Support
YIFENG CAT expanded cooperation with buyers across different regions and application scenarios, including aftermarket distributors, repair supply channels, industrial users and project-based customers.
Scaling Forward with Integrated Manufacturing
The company continues to invest in production efficiency, coating capability, inspection standards and customer support. Future development focuses on more stable batch production, clearer technical communication and stronger support for buyers facing changing emission standards.
