Quality Assurance


         Dongrun Casting Company's ISO 9001:2015 certified Quality Management System ensures advanced quality and production planning. We employ various measures such as          Part Control Plans, Process Flowcharts, and Process Failure Mode & Effects Analysis to prevent defects. We utilize sophisticated measuring equipment including          spectrometers and coordinate measurement machines. Quality control measures include first-piece inspection, SPC charting, last-piece inspection, and final audits. Their quality          policy emphasizes a culture of continuous improvement, with employees committed to manufacturing products to requirements, eliminating defects, and participating in          training for quality improvement.

Advanced Quality/Production Planning

        ❖   A Part Control Plan is generated for each part manufactured identifying all key product characteristics and defining the methods for their control.

        ❖   A Process Flowchart is generated and defines the manufacturing process as well as the interaction and controls throughout the product realization.

        ❖   Process Failure Mode & Effects Analysis is performed to assure the prevention of defectives through the manufacturing process.

        ❖   A Full Metrology Review of the key parameters is performed and methods established to assure design intent is met.

        ❖   A Full Dimensional Layout is performed to verify mold design and part print compliance in the pre-production phase.

Measuring Equipment

        ❖   Spectrometer for Spectrographic Analysis of Raw Material

        ❖   Hardness Testing Meter, Ultimate Testing Meter and Yield Testing Meter for Mechanical Properties Analysis of Raw Material

        ❖   Degassing Equipment for Melting Process

        ❖   Micro-Structure Equipment for Casting Inside

        ❖   Coordinate Measurement Machines for full dimensional layout

        ❖   No-Go and Go Gauge, Micrometers, Height Gauges, Calipers, Thread Gauges, Bore Gauges and Ring gauges

 Quality Control

        ❖   Part Qualification: First-Piece Inspection at the start of each production run

        ❖   SPC: Variable and Attribute Control Charting during the production run

        ❖    Part Evaluation: Last Piece Inspection at the end of each production run

        ❖   Final Audit: Random sampling of each ship lot for compliance of key characteristics

Quality Policy

Achieving our Mission will be a direct result of our Company's Quality Improvement Culture. Our Culture is a product of each individual employee's attitudes and conduct. Each employee is obligated to:

        1. Manufacture products to established requirements, or cause the requirements to officially change.
