The Definitive Checklist for Sourcing High-Quality Cast Iron Gas Stove Grates from China

Introduction

Finding a supplier with a low price is easy. Finding a long-term partner capable of delivering consistent quality requires a disciplined approach. This practical checklist guides you through the critical steps of vetting a potential cast iron grate supplier in China.

Part 1: Factory Audit & Capability Assessment

1. Specialization & Certification: Does the factory specialize in cookware hardware casting? Is it certified with ISO 9001 for Quality Management?

2. Foundry Workshop: Inspect melting equipment (medium-frequency electric furnace), mold precision, and condition.

3. Enamel Line: Does it have a complete (automated or semi-automated) spraying line? Is the temperature control of the firing kiln precise and stable?

4. QC Lab: Check for basic testing equipment like coating thickness gauges, cross-cut adhesion testers, and salt spray test chambers.

Part 2: Product Quality Verification

1. Material Certificate: Can they provide a Material Test Certificate (e.g., for HT250 Gray Cast Iron)?

2. Finished Product Check: Sample products for: smooth, pore-free enamel surface; rounded edges without burrs; consistency in weight and dimensions with the approved sample.

3. Performance Reports: Request the supplier's Salt Spray Test Report (typically >72 hours without red rust) and Load Test Report.

Part 3: Partnership Flexibility Evaluation

1. Customization Capability: Are they willing to accept low Minimum Order Quantity (MOQ)? How responsive are they to design modifications?

2. Sampling Process: Is the sampling procedure professional? Are the sampling fee and lead time reasonable?

3. Communication & Compliance: Is the sales team knowledgeable? Can they handle all necessary export documentation?
