Precision Parts: First Article Inspection Starts With Your Drawing
Upload your drawing for first-article inspection planning that reviews critical dimensions, material, process route, and reporting needs before production.
First Article Inspection Starts With Drawings
SUUXIANG is the sole public-facing brand of Dongguan SuuXiang Precision Mold Co., Ltd., established in 2010 in Chang’an Town, Dongguan, Guangdong, China. Founded by XiaoCheng Huang, the company helps engineering and sourcing teams convert controlled drawings, models, and specifications into inspected custom CNC parts, precision mold components, connector tooling, and die components.
Our first article inspection workflow begins before production: reviewing revision status, critical dimensions, datums, material and heat-treatment requirements, surface needs, machining access, EDM strategy, grinding stock, and inspection expectations. Process planning may combine CNC machining, EDM, precision grinding, fitting, and measurement according to the verified needs of the project.
What distinguishes SUUXIANG is disciplined coordination from drawing review through final documentation. We do not treat a first article as a generic sample; it is a documented checkpoint against the agreed order and inspection plan. Capability, timing, and reporting commitments are confirmed against current project evidence before production proceeds.
Before Production: First Article Inspection Verification
Review the decision inputs that connect your drawing, process route and inspection plan before production commitments are made.
Critical Dimensions
Identify CTQ dimensions, geometric controls and functional interfaces that require focused measurement before production commitments are released.
Datum Strategy
Confirm drawing datums align with inspection setup, feature relationships and measurement methods, reducing ambiguity in positional and profile evaluation.
Process Access
Review cutter reach, workholding, electrode strategy, wire paths and grinding stock before selecting a stable route for critical features.
Inspection Expectations
Define which dimensions need recorded results, how surfaces are evaluated, and what traceability or reporting accompanies the approved first article.
How SUUXIANG Plans a First Article Inspection
Align the drawing, process route, critical dimensions and inspection evidence before production proceeds.
Submit Your Drawing Package
Provide the current 2D drawing, available 3D model, material, quantity, delivery target, revision level, and any application or mating-component requirements.
Define Critical Requirements
Review datums, tolerance stack, surface requirements, heat-treatment sequence, critical-to-quality dimensions, inspection needs, and revision-controlled notes before committing to a process route.
Plan the Manufacturing Route
Align CNC machining, EDM, grinding, fitting, machining allowances, tool access, and measurement methods with the drawing and verified project requirements.
Inspect the First Article
Compare the first article against the approved drawing and inspection plan, documenting measured characteristics and any findings requiring engineering clarification or correction.
Control Revisions Before Production
Resolve approved changes, confirm the applicable revision and inspection expectations, then coordinate subsequent production using the documented manufacturing and quality plan.
First Article Inspection for Critical Tooling Parts
Align drawing review, process planning, critical dimensions and inspection evidence before releasing custom tooling and precision-machined components to production.
CNC Machining Services
Precision CNC machining services begin with a first-article review of the drawing, material, datums and critical dimensions. The inspection plan confirms that the selected milling, turning, EDM or grinding route can be evaluated before subsequent parts proceed.

CNC Milling
Custom CNC milling services use first-article inspection to verify machined features, datum relationships, tool access and surface requirements. Review results help establish whether fixture strategy, machining allowance or inspection method needs adjustment before production quantities are released.
Upload a Drawing
CNC Turning
Precision CNC turning services require first-article checks on diameters, concentricity, threads, shoulders and functional interfaces. The drawing and inspection approach should identify critical turned features, material condition and any secondary machining or grinding required for final acceptance.

Wire & Sinker EDM
Wire EDM and sinker EDM services should be reviewed through first-article evidence for slot width, corner condition, wire path, electrode detail and surface requirements. The plan should also account for machining sequence, EDM allowance and any follow-on grinding or fitting.

Precision Grinding
Precision surface and profile grinding requires first-article verification of flatness, parallelism, profile accuracy and final stock removal. Drawing review should establish the datum scheme, grinding allowance, material condition and inspection method for features that affect tooling fit or function.
Upload a Drawing
Mold Core & Cavity Inserts
Precision mold core and cavity inserts are first-article reviewed against cavity geometry, shutoff areas, critical interfaces and finishing requirements. Inspection planning helps confirm the machining, EDM and grinding sequence before inserts move into mold assembly or customer validation.

Ejector & Ejection Components
Ejector pins, sleeves and ejection components require dimensional confirmation of sliding fits, working lengths, diameters and mating relationships. First-article evidence should link the drawing requirements to material, heat treatment, finish and inspection expectations before the set is released.

Core Pins, Guide & Locating Components
Core pins, guide pins and locating components depend on controlled diameters, alignment features and mating fits. First-article inspection should verify critical relationships, datum references and surface condition so mold positioning and repeatable assembly can be assessed early.
Upload a Drawing
Slides, Lifters, Gates & Mold Accessories
Mold slides, lifters, gates and accessories require first-article review of travel interfaces, shutoffs, locating faces and functional clearances. The inspection plan should reflect machining access, EDM detail, grinding stock and any fitting information needed for assembly.
Upload a Drawing
Connector Mold Components
Precision connector mold components need first-article control of fine features, pin or cavity relationships, alignment surfaces and mating geometry. Drawing review should identify critical dimensions, material and finish requirements, plus inspection evidence appropriate to connector-tooling function.
Upload a Drawing
Stamping Die Components
Precision stamping die components should be first-article inspected for profiles, cutting edges, clearances, locating features and working interfaces. The review aligns machining, wire EDM, grinding and heat-treatment sequence with the dimensions that govern die performance and assembly.

Machining Materials
CNC machining materials should be specified in the RFQ and checked during first-article planning against drawing requirements, material condition and downstream processes. Include material grade, heat-treatment needs and any application constraints that influence machining, inspection or documentation.
Upload a Drawing
Surface Finishes & Heat Treatment
Surface finishing and heat treatment can change dimensions, surface condition and fit. First-article planning should define process sequence, masking or stock allowances where needed, and the inspection points required after treatment to verify the drawing’s critical requirements.

Quality, Metrology & Documentation
Precision inspection, metrology and quality documentation should be planned from the drawing’s critical dimensions, datums and reporting requirements. First-article records provide traceable evidence of the agreed measurement method, revision level and acceptance criteria before production release.
Upload a Drawing
Prototyping & Low-Volume Production
Rapid prototyping and low-volume manufacturing benefit from first-article inspection because design changes and process choices can be resolved early. Submit the drawing, model, material, quantity, quality needs and delivery target so the inspection plan matches the intended build.
