01Design Phase

YJF controls quality right from the beginning of the casting process. Every batch of raw material must pass incoming inspection. With proprietary CAE casting simulation applied in the early stage, we identify all key parameters for casting formation and precisely control hot spots, shrinkage, and inclusion patterns throughout pouring and solidification.

02Casting Phase

With advanced melting technology, we ensure that our product maintain accuracy even under heavy-duty loading conditions.During solidification, we control complex solidification behavior and combine it with in-house heat treatment to deliver stable, finished castings.

03Machining Technology

Our machining processes include milling, drilling, heat treatment and grinding for large iron castings.Some of our machining equipments are large gantry milling machines from EU and five-axis mill-turn machining centers from Japan.

04Quality Assurance and CMM Reporting

Key QA equipment in our foundry includes spectrometers, metallographic analysis systems, ultrasonic testing equipment, and full-process inspection for resin, sand and hardeners. Before shipment, we provide complete CMM (Coordinate Measuring Machine) reports to verify the dimensional accuracy of every casting product.

05After-Sales Service

After-sales service is the backbone of our castings in the field. To YJF, the connection with each customer and each casting just begins after the product ships to our customer. We provide full digital traceability for every casting. QR codes are used to record and link process info, enabling fast tracking and verification whenever customers requires.

06International Certifications

As a Meehanite licensed foundry and an ISO 9001-certified manufacturer, we want to be a sustainable corporate, and our ISO 14001, ISO 14064-1 and ISO 14067 are ready here to pin the starting point of our ESG roadmap.
