Production stages buyers can review

  1. 1

    Melting

    Qualified iron material is melted at high temperature before cast iron cookware bodies are formed.

    Proof points: Material preparation; High-temperature melting; Casting batch start

  2. 2

    Casting

    Automated sand-mold forming and molten iron pouring create the cookware body before cleaning and surface preparation.

    Proof points: Sand-mold forming; Molten iron pouring; Cookware body forming

  3. 3

    De-sanding

    The sand mold is removed and the semi-finished cookware body is cleaned before surface treatment.

    Proof points: Mold removal; Blank cleaning; Semi-finished body review

  4. 4

    Shot blasting

    Shot blasting removes scale and prepares the casting surface for grinding, coating, seasoning, or machining.

    Proof points: Scale removal; Surface preparation; Casting surface review

  5. 5

    Grinding

    Manual and machine grinding help keep the cookware blank flat, smooth, and ready for the selected finish.

    Proof points: Manual grinding; Machine grinding; Surface flatness review

  6. 6

    Base QC

    Base casting inspection screens qualified blanks before enamel, pre-seasoning, nitriding, or CNC machining.

    Proof points: Casting surface check; Blank selection; Process routing decision

  7. 7

    Surface treatment routing

    Qualified blanks route into enamel coating, pre-seasoning, nitriding, or CNC precision machining depending on the buyer program.

    Proof points: Finish selection; Line routing; 6 specialized production lines

  8. 8

    Final QC and assembly

    Final QC checks coating consistency, color difference, logo clarity, cookware parts, knobs, handles, and buyer-specific requirements.

    Proof points: Final QC; Coating and color review; Logo and accessory assembly

  9. 9

    Checking and packing

    Packing follows buyer requirements such as reinforced cartons, mail-order boxes, foam protection, carton marks, and packing lists.

    Proof points: Packaging check; Carton mark review; Packing list preparation

  10. 10

    Ready for shipping

    Finished goods enter the warehouse and wait for freight-forwarder pickup, loading, and shipment handoff.

    Proof points: 10,000 m²; Warehouse handoff; Freight-forwarder pickup

  11. 11

    Shipment and 3% random inspection

    Before loading, the factory can apply buyer carton marks and packing lists, then perform a 3% random inspection before shipment.

    Proof points: Carton marks; Packing list; 3% random pre-shipment inspection

Buyer FAQ

Factory process questions buyers ask before RFQ.

What is the cast iron cookware manufacturing process?

The confirmed process covers melting, casting, de-sanding, shot blasting, grinding, base QC, surface-treatment routing, final QC, assembly, checking and packing, warehouse handoff, shipment preparation, and 3% random pre-shipment inspection.

Where do enamel, pre-seasoning, nitriding, and CNC machining fit into the process?

Qualified blanks route into the selected surface treatment after casting preparation and base QC. The finish path depends on product type, target market, buyer requirements, sample approval, and packaging channel.

Which QC checkpoints should buyers review before mass production?

Buyers should review base casting QC, shot blasting and grinding review, enamel or non-enamel process checks, sample inspection, product or packaging tests when relevant, and 3% random pre-shipment inspection before loading.

What should buyers include in a factory process RFQ?

Include product category, size, finish, target market, quantity, logo or packaging needs, sample timing, required documents, inspection expectations, carton channel, and shipment handoff requirements.
