Practical Quality Control for Custom Hardware Parts
We focus on clear drawing confirmation, key dimension checking, surface finish review and export packaging control to help reduce quality risks in custom hardware projects.
From Drawing Review to Final Shipment
For custom CNC parts and special fasteners, quality control starts before production. We review drawings, confirm key requirements and check important details during production and before shipment.
Drawing & Requirement Review
We check drawings, tolerances, material notes, surface finish requirements and special assembly details before production.
Material Confirmation
Material grade and condition are confirmed according to drawings or customer requirements before machining or fastener production.
First Article Check
Key dimensions, thread fit, appearance and process feasibility can be checked before moving into larger production.
In-process Inspection
Important dimensions, machining details, threads and surface condition are reviewed during production when needed.
Surface Finish Review
Anodizing, passivation, plating, black finish, PVD black and laser marking are checked for appearance and basic consistency.
Final Packing Check
We review quantity, packaging, labeling and protection before shipment to reduce transport and handling risks.
Key Details We Pay Attention To
Different products require different control points. We focus on the details that may affect assembly, function, appearance and shipment.
Dimensions
Outer diameter, hole size, length, thickness, grooves, chamfers and key tolerance areas.
Threads
Thread size, thread depth, go/no-go gauge checking and assembly fit where required.
Appearance
Machining marks, burrs, scratches, color difference, coating defects and visible surface issues.
Surface Finish
Anodizing, passivation, plating, black oxide, phosphating, PVD black and laser marking.
Packaging
Part separation, protection, cartons, labels, pallets and shipping method requirements.
Documents
Packing list, invoice, material information or inspection photos when required by the project.
