Mold Workshop: Strong cast iron foundries have independent mold workshops and advanced mold-making equipment, enabling them to complete the entire mold-making process independently.

Adaptability: A qualified cast iron foundry should customize molds per casting type, structure and batch.

Material and Lifespan: Wooden molds for small-batch production, iron molds / shell-molding for large-batch consistency.

Mold-Repair Speed: In-house workshop = 1-3 days repair; Outsourcing = 1-2 weeks delay.

Production Line Type: Automated lines for small parts, resin-sand lines for large complex castings.

Production Capacity: Verify daily/monthly capacity & order schedule to ensure on-time delivery.

Supporting Processes: One-stop casting + post-treatment ensures stable quality & fast lead time.

Smelting Control: Medium-frequency induction furnaces + composition testing guarantee material performance.

Environmental Protection Qualifications: Legal & clean facilities avoid order interruption risks.

Complete Equipment: Spectrometers, metallographic microscopes & universal testing machines for full inspection.

Perfect Process: Full-process testing from raw materials to finished castings.

Formal Reports: Traceable test reports avoid quality disputes.

Quality Control Team: Professional QC team ensures stable & consistent quality.
