Jingong Casting Quality Control Workflow

We follow a practical quality control workflow to help customers reduce production risks, improve part consistency, and keep each casting and machining project under clear process control.

From Drawing Review to Final Delivery

Our quality system focuses on prevention, process control, inspection, and final verification. Before production, we review drawings, materials, tolerances, and key application requirements. During manufacturing, we control each critical step from casting to CNC machining, inspection, packing, and shipment.
01
Drawing & Requirement Review

We review customer drawings, specifications, materials, tolerances, surface requirements, and application details before production starts.

02
Material & Process Preparation

Materials, tooling plans, casting methods, and machining requirements are checked according to project needs to support stable production from the beginning.

03
Casting Process Control

We control key casting steps such as mold preparation, melting, pouring, cooling, cleaning, and defect checking to reduce unstable quality risks.

04
CNC Machining Inspection

Key dimensions, tolerance points, assembly surfaces, holes, threads, and machining finishes are inspected with suitable measuring tools and equipment.

05
Final Inspection & Packing Check

Before shipment, finished parts are checked against drawings, inspection requirements, surface condition, quantity, and export packaging standards.

06
Records & Continuous Improvement

Inspection feedback, production records, and project experience are reviewed to support repeat orders, batch consistency, and long-term quality improvement.
