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.
❖ 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
❖ 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
