How are quality issues handled after purchase?

Quality inspection can be conducted within 7-15 days of receipt. For non-human-induced quality issues, we support replacement, return, or rework. Some products include a warranty period for free repair or replacement.

Why do prices vary between different manufacturers?

Prices depend on material purity, weight, processing complexity, surface treatment, and order quantity. Differences often stem from material composition, casting process (sand vs. precision), and inspection standards.

Product Q&A

Q:What types of cast iron are available and their applications?

We offer ductile iron for impact resistance (e.g., drive shafts), gray iron for vibration damping (e.g., machine beds), malleable iron for pipe fittings, and vermicular graphite iron for high-temperature conditions (e.g., exhaust pipes).

Q:How can I verify the strength and hardness of the components?

Components meet clear performance standards (e.g., ductile iron 400-800MPa). You can request material certificates, tensile test reports, and Brinell hardness data to ensure compliance with your operating load requirements.

Q:What anti-rust treatments are provided for cast iron components?

We provide surface painting, galvanizing, chrome plating, anti-rust oil, and passivation for special scenarios. We ensure the treatment matches your storage or usage environment for weather resistance.

Q:Is customization available and what is the MOQ?

Yes, we support full customization including material, size, and structure based on your drawings. MOQ varies: 10-50 units for standard products, 50-100 for complex parts, and small-batch sampling (3-5 units) is supported.

Q:What is the expected service life of the cast iron components?

Under normal conditions, gray iron lasts 5-10 years and ductile iron lasts 10-20 years. Cracking is rare if selection is correct, installation is standardized, and sudden temperature changes or severe impacts are avoided.
