 Our FAI is not a signed sheet saying "sample passed"—it is a confirmation document that locks down process conditions, dimensional data, appearance standards, and material information.

I. Basic Information and Traceability

We record the project name and drawing number, mold number, material grade and batch number, molding machine number, production date and shift, and signatures of the confirmer and reviewer. For any first article sample, Haina can trace it back to the specific material batch, machine, and operator.

II. Full Process Parameter Records

We record barrel zone temperatures, mold temperature, injection speed and pressure, holding pressure and time, cooling time, screw speed and back pressure, etc., forming Haina's standard process card. What customers see is not just "sample passed," but "under what conditions it passed"—this determines whether mass production can be stably reproduced.

III. Dimensional Inspection Data

Haina lists each key dimension with nominal value, tolerance range, measured value, and judgment result. For assembly-critical dimensions (hole positions, flatness, mating surfaces), we perform full inspection rather than sampling. It is not just the word "passed"—every value is traceable.

IV. Appearance and Color Confirmation

We confirm color consistency against standard samples, record surface defect judgment criteria and surface treatment confirmation, and attach first article photos or physical retained samples as the benchmark for subsequent batch comparison.

V. Assembly and Functional Verification

Haina records fit clearance, insertion/withdrawal force, sealing tests, and measured flatness values. For easily deformed parts such as die-cast aluminum housings, we record flatness data after CNC secondary machining to confirm assembly feasibility.

VI. Material Compliance and Certification Information

For food-contact orders, we attach FDA compliance statements or LFGB test report numbers, compliance certificates for masterbatch and additives, and mold release agent model descriptions. Customers often check this during factory audits; Haina puts it directly into the FAI, saving the time of repeatedly requesting documents.

VII. Abnormality Records and Rectification Confirmation

Defects that occurred during trial molding, cause analysis, corrective measures, and verification results are all included. What customers want to know is not just "it passes now," but "you know why it failed before and have confirmed it is fixed."

VIII. Conclusion and Signatures

Whether the first article passes, whether mass production conditions are met, and items requiring follow-up are signed and confirmed by Haina's engineering, quality, and production teams.

Haina's FAI is essentially about breaking down "passed" into verifiable data and conditions: materials traceable, processes recorded, dimensions measured, appearance benchmarked, assembly verified, compliance documented, and abnormalities closed-loop.
