Inter-Process Quality Control Control risks at critical process interfaces and close quality issues through fast feedback. Integrated manufacturing makes adjacent processes jointly responsible for final quality. ### Why Process Interfaces Matter #### Upstream Output → Downstream Input #### Downstream Issue → Upstream Feedback #### Drawing / CTQ / Batch Continuity ### Critical Process Interface Map - Input: Tooling - Output: Forming ##### Risk - Dimensional variation - Venting / gate ##### Control - Tool validation - Trial confirmation ##### Result - Resolve before mass production - Stabilize trial results - Input: Forming - Output: Machining ##### Risk - Blank distortion - Uneven allowance ##### Control - Blank inspection - Unified datums ##### Result - Stable clamping - Reduce stock shortage - Input: Machining - Output: Finishing ##### Risk - Burrs / contamination - No coating allowance ##### Control - Deburr and clean - Dimensional compensation ##### Result - Prevent post-finish failure - Protect functional surfaces - Input: Finishing - Output: Assembly ##### Risk - Coating buildup - Poor fit / contact ##### Control - Thickness verification - Protect critical surfaces ##### Result - Lower assembly risk - Maintain appearance - Input: Assembly - Output: Functional Test ##### Risk - Wrong orientation - Torque / press error ##### Control - Assembly SOP - Torque and function test ##### Result - Consistent function - Correct dimensional fit - Input: Inspection - Output: Delivery ##### Risk - Lot / label error - Weak packaging ##### Control - Batch verification - Packaging validation ##### Result - Consistent delivery data - Damage and error prevention ### Internal Quality Loop Cross-process control · fast feedback · full traceability #### Cross-Process Joint Review Unified datums, allowance and finishing requirements #### Fast Upstream Feedback Return issues directly to the responsible process #### Unified Records & Impact Review Retain records and confirm the affected range ## 04. Zhongde Integrated Factory vs. Multi-Supplier Production Reduce quality variation, coordination cost and delivery risk through fewer supplier interfaces. ### Multi-Supplier Production Multiple factories · repeated handoffs #### Process Nodes ##### Customer ##### Tooling ##### Forming ##### Machining ##### Finishing ##### Assembly #### Process Handoffs - Contact - Transport - Recheck - Waiting - Handoff #### Risks - Multiple contacts - Information gaps - Repeated inspection - Complex ownership ### Zhongde Integrated Factory Continuous progress within one factory #### Control Items - Unified revisions - Engineering control - Quality records - Batch traceability #### Process Nodes ##### Review ##### Material / Tooling ##### Forming ##### Machining ##### Finishing ##### Assembly ##### Delivery #### Engineering Benefits - One project window - Faster feedback - Lower interface risk - Stable scheduling ### Comparison Dimensions #### Communication - Multi-Supplier Model: Multiple contacts - Integrated Model: One window #### Revision Control - Multi-Supplier Model: Distributed - Integrated Model: Unified #### Process Flow - Multi-Supplier Model: Repeated transport - Integrated Model: Internal linkage #### Quality Issues - Multi-Supplier Model: Slow cross-factory search - Integrated Model: Fast internal loop #### Scheduling - Multi-Supplier Model: Mutual dependency - Integrated Model: Unified coordination #### Traceability - Multi-Supplier Model: Scattered data - Integrated Model: Full linkage ### Customer Value - Fewer supplier interfaces - Lower inter-process defects - Faster issue identification - Lower coordination cost ## 05. One-Stop Manufacturing RFQ & FAQ Complete product data, process scope and quality requirements help the engineering team plan the manufacturing route, identify interface risks and define the quotation scope. ### Recommended Information for RFQ Review Items that are not yet defined may be left open and confirmed during engineering review. Individual or partial processes can be commissioned. When Zhongde manages several core processes together, quality closure and delivery coordination are more effective. #### Engineering Items ##### Drawings & BOM 2D drawings, 3D models, assembly drawings and parts list ##### Material & Condition Material grade, heat-treatment condition, specification and source ##### Manufacturing Scope Tooling, forming, machining, finishing, assembly and inspection ##### Quality & CTQs Critical dimensions, appearance, function and inspection methods ##### Quantity & Project Stage Prototype, pilot run, mass-production quantity and annual demand ##### Delivery & Traceability Packaging, labels, reports, batch records and delivery schedule ### Common Engineering Questions Common questions about process scope, quality interfaces, traceability and production launch. #### Engineering Items ##### Which core processes can Zhongde connect within one factory? Depending on the project, Zhongde can connect material confirmation, tooling, forming, precision machining, surface finishing, assembly, inspection and delivery. Customer-specified or special processes are confirmed during RFQ review. ##### Can a customer commission only part of the manufacturing route? Yes. Customers may request one process, several connected processes or the complete manufacturing route. For multi-process projects, final product requirements help define datums, allowances, coating thickness and assembly relationships. ##### How are coating thickness and fit dimensions controlled? Functional surfaces, masking areas, coating thickness and dimensional compensation are confirmed during engineering review. Samples or first articles are validated before production, followed by checks of critical dimensions, thickness, appearance and fit. ##### How can a quality issue be traced to a process and batch? Production orders, material batches, process inspections, equipment or process records, assembly records and packaging labels remain linked. This supports identification of the source process, related batches and affected product range. ##### What must be confirmed before moving from prototype to mass production? Typical confirmations include drawing revision, process route, tooling or fixture validation, first-article inspection, CTQs, surface and functional validation, packaging approval and production change control.
