Quality Control & Inspection for Forged and CNC Machined Components

Quality control is a core manufacturing capability at Weforging. Rather than being limited to final inspection, quality control for forgings is integrated across the entire manufacturing process, from raw material preparation and forging to CNC machining, heat treatment, and final delivery. This systematic approach supports dimensional accuracy, mechanical performance, and production consistency for forged and machined components used in OEM and industrial applications.

Quality Control Integrated Across the Manufacturing Process

Quality control for forgings at Weforging begins at the early stages of production and continues through each manufacturing operation. Key process parameters are monitored and documented to maintain stable and repeatable manufacturing conditions. By embedding inspection and verification within each stage, quality is managed proactively rather than corrected at the end of production.

Inspection Capabilities

Weforging operates a dedicated inspection and testing system to support the inspection of forged and machined parts at different production stages. Inspection methods are selected based on component geometry, application requirements, and customer specifications.

Inspection capabilities include:

  • Dimensional inspection using CMMs and precision measuring instruments

  • Gear inspection and tooth profile verification for gears and gear shafts

  • Ultrasonic testing (UT) for internal integrity evaluation

  • Magnetic particle testing (MT) for surface and near-surface inspection

  • Mechanical property testing, including tensile and yield strength verification

  • Hardness testing after forging and heat treatment

  • Metallographic analysis to evaluate material microstructure

The equipment is applied to check external dimensions, profiles, and geometric features of forged and CNC machined components. Optical inspection supports accurate verification against technical drawings and contributes to stable quality control throughout the manufacturing process.

In-Process Quality Control

During forging and CNC machining, in-process inspections are applied to verify critical dimensions, concentricity, runout, and tolerance requirements. Monitoring of forging temperature, deformation ratio, machining allowances, and heat treatment cycles supports dimensional consistency and reduces variation within production batches.

Traceability and Documentation

Full traceability is maintained as part of Weforging’s OEM quality control manufacturing system. Each production batch is linked to complete material, process, and inspection documentation, supporting transparency and long-term quality management.

Traceability documentation includes:

  • Raw material certificates and heat numbers

  • Heat treatment records and process parameters

  • Dimensional inspection reports

  • Non-destructive testing records (UT / MT)

  • Mechanical property test results

Quality Standards and Compliance

Weforging operates under an ISO 9001-certified quality management system. Quality control for forgings and CNC machined components follows recognized ISO standards for dimensional control and process management.
For gear and transmission parts, inspection procedures align with AGMA and DIN standards. Material selection and testing reference commonly used ASTM (North America) and EN (Europe) standards, supporting OEM requirements across different regions.
Inspection scope and acceptance criteria are defined based on customer drawings and technical specifications.

Quality Control Supporting OEM and Industrial Applications

At Weforging, quality control is treated as a core manufacturing capability that directly supports OEM and industrial applications. Through controlled production processes, documented inspection, and full traceability, we help ensure predictable assembly fit, stable operation, and long-term service performance.

This quality system supports forged and CNC machined components used in mining equipment, transmission systems, heavy machinery, and hydraulic applications, enabling OEM customers to achieve consistent quality, controlled risk, and reliable performance across global supply chains.

Conclusion: Quality You Can Rely On

At Weforging, quality control is fully integrated into every stage of forging and machining. Through standardized processes, documented inspection, and full traceability, we help OEM customers achieve consistent quality, predictable performance, and controlled manufacturing risk across global supply chains.

If you are evaluating suppliers or preparing a new project, Weforging supports technical review, quality documentation, and drawing-based inspection planning.
