Dongguan Changdong Tool & Die Co., Ltd. is an ISO 9001 and IATF 16949 certified metal stamping die manufacturer in China. These certifications support our quality management system for custom metal stamping dies, automotive stamping dies, progressive dies, transfer dies, prototype dies, sheet metal stamping parts, die tryout, and dimensional inspection.

For customers in automotive, appliance, electrical hardware, industrial equipment, and custom sheet metal applications, certification is not only a document. It shows that the manufacturer has established quality procedures, process control, inspection discipline, and continuous improvement requirements throughout the production workflow.

ISO 9001 Certification

ISO 9001 certification reflects Changdong's commitment to quality management, standardized process control, customer satisfaction, and continuous improvement. For stamping die manufacturing, this means quality is managed through drawing review, material confirmation, machining control, assembly inspection, tryout validation, and final delivery review.

A stamping die project involves many connected steps. If one process is not controlled properly, it may affect machining accuracy, die assembly, tryout performance, stamped part dimensions, or delivery timing. ISO 9001 helps Changdong maintain a structured management system for these processes.

IATF 16949 Certification

IATF 16949 is especially important for automotive-related manufacturing. It focuses on defect prevention, process stability, risk control, traceability, continuous improvement, and customer-specific requirements in the automotive supply chain.

As an IATF 16949 certified automotive stamping die manufacturer, Changdong applies quality management requirements to automotive tooling projects, stamping die tryout, prototype stamping, sheet metal stamping parts, inspection records, and project communication.

What These Certifications Mean for Customers

For customers, ISO 9001 and IATF 16949 certifications provide confidence that Changdong has a structured quality management system instead of relying only on final inspection. In stamping die and sheet metal stamping projects, early process control is often more important than checking problems after they occur.

• More disciplined drawing review and technical communication

• Better control of material, machining, assembly, and tryout processes

• Improved inspection records for tooling components and trial parts

• Stronger support for automotive project quality requirements

• More stable project management from prototype to production preparation

• Continuous improvement for quality, delivery, and customer satisfaction

Quality Control Across the Tooling Process

Changdong applies quality control throughout the stamping die manufacturing workflow. Each project may involve technical review, design confirmation, machining inspection, die assembly checks, tryout adjustment, sample validation, and dimensional inspection before delivery or production preparation.

• Drawing and 3D data review before tooling design

• Material confirmation according to project requirements

• Machining inspection for die plates, inserts, punches, and tooling components

• Die assembly checking before press tryout

• Tryout sample inspection for hole position, forming quality, trimming, and burr condition

• CMM measurement, 3D scanning, and other inspection methods when required

Certification Support for Automotive Stamping Die Projects

Automotive stamping die projects usually require stricter control than general industrial tooling. Customers may require dimensional stability, sample validation, process documentation, defect prevention, engineering change control, and continuous improvement.

Changdong's IATF 16949 certified system supports automotive stamping die projects involving brackets, reinforcements, body structures, chassis-related parts, prototype vehicle parts, and other functional sheet metal components.

Inspection and Equipment Support

A certified quality system also needs the right inspection and production resources. Changdong supports quality control with CMM measurement, 3D blue laser scanning, hardness testing, height measurement, micrometers, gauges, and other inspection tools. These inspection methods help verify tooling components, stamped samples, and key dimensional features.

Our manufacturing resources include CNC machining centers, wire cutting, milling, grinding, welding, die assembly areas, and press capacity from 45T to 800T. These resources help connect quality management with actual stamping die manufacturing and validation.

Continuous Improvement

Certification is not a one-time result. Changdong uses quality system requirements to support continuous improvement in project communication, supplier coordination, internal training, process control, inspection methods, and customer feedback handling.

This approach helps reduce repeated tooling correction, improve sample approval efficiency, strengthen delivery reliability, and support long-term cooperation with customers in automotive, appliance, electrical hardware, industrial, and custom metal stamping projects.
