Aipu Solids Control operates a thorough shale shaker equipment incoming inspection process that verifies all purchased materials and components meet specifications before entering production. The incoming inspection function serves as the first line of quality defense, preventing non-conforming materials from reaching production operations where they could cause manufacturing disruptions, rework costs, and potential field reliability issues.


Inspection Planning and Sampling
Incoming inspection plans are developed based on component criticality classification, supplier performance history, and the characteristics requiring verification. Critical safety and performance components including motor assemblies, structural steel certification, and bearing kits receive 100% inspection or statistically valid sampling plans based on Acceptable Quality Level standards. Less critical items may receive reduced inspection based on demonstrated supplier capability and consistent conformance history. Sampling plans are dynamically adjusted based on supplier performance trends, with tightened inspection for suppliers showing quality degradation and reduced inspection for suppliers demonstrating sustained high performance.
Inspection Methods and Equipment
The incoming inspection laboratory is equipped with comprehensive measurement and testing capabilities. Coordinate measuring machines verify dimensional conformance of precision-machined components with accuracy to microns. Material certification verification confirms that received steel, alloys, and composite materials match ordered specifications through spectrometer analysis and mechanical property testing when required. Surface finish measurement, hardness testing, and non-destructive examination techniques including dye penetrant and magnetic particle inspection are applied as specified by component inspection plans. Functional testing of electrical and electronic components verifies performance before release to production.
Non-Conformance Management
When incoming inspection identifies non-conforming material, a structured non-conformance management process is immediately activated. Non-conforming items are clearly identified, segregated from conforming inventory, and documented in the quality management system with detailed description of the discrepancy. Supplier corrective action requests are issued requiring root cause analysis and corrective action plans within defined timeframes. Material review board decisions determine disposition options including return to supplier, rework where technically feasible, or use-as-is with documented justification and customer notification where applicable. Non-conformance data is trended to identify systemic supplier issues requiring escalated intervention or potential re-sourcing decisions.
