Inspection Procedure
and Quality Control

Tri-State Flame Hardening Company has implemented a comprehensive four-part inspection process for exceptionally high level of Quality Control.

Receiving Inspection
Received material shall be inspected to verify the acceptability. Customer furnished material will be visually examined unless a possibility exists that material may be non-conforming. If an inspection verifies a non-conformance exists, the customer will be notified immediately per corrective action procedures.

Sub tier supplier furnished material must be inspected to receiving inspection documents to include drawing and specifications. Any material non-conforming will be segregated and tagged. Accepted material will be sent to stores. Non-conforming material will be returned to supplier for replacement or reworded to print tolerance.

Raw stock material will be verified to specification and certification. If accepted, proper stock control will be maintained.

All inspection rates will be based on the customer's purchase order. MIL STD 105 will be utilized depending on customer's purchase order.

In Process Inspection
Inspection will be conducted on all hardware through hardening or straightening to ensure quality control.

Certain key inspection points will be maintained to establish that manufacturing operations will provide a means to produce a quality acceptable final part.

To verify proper operations, the first part shall be verified 100% to establish proper operations to include assembly, machining or fabrications. The in-process inspections will be verified by either toll gate, fixed station or roving inspections.

All first article inspections will be documented and will be available upon customer request.

All in-process inspection other than first article will be initiated by the inspector on material travelers.

Prior to any utilization of AQL sampling methods, validation of zero defects must be achieved on a sufficient number of consecutive pieces produced from production.


Final Inspection
Final inspection will be conducted per either customer instruction or at a rate of 100%.

All hardware offered to inspection will be in the condition that is deliverable to the customer.

Proper documentation to include all pertinent test data will accompany the hardware offered to final inspections.

If acceptance is granted, all documentation will be completed and material moved to controlled stores or shipping. Certifications for conformance will be completed and remain with the documentation for the customer's verification.


Shipping Inspection
All accepted hardware being prepared for shipment to customer will be prepared to ensure the best commercial means of packing in order to preclude any damage to the shipment.

Hardware to be inspected for completeness, no damage, part number marking (MIL STD 180 and/or 129 may apply) and packaged to either packaging instructions furnished by customer or in a means compatible to preclude any shipping damage.
Any non-compliance will be cause for rejection of the lot.

Rejected Hardware
Hardware rejected at any inspection point will be tagged with a red Hold Tag and segregated in a designated area that is way from the production flow.

Hardware will be reviewed for compatibility of rework print.

Rework analysis will be the joint decision of the Quality Manager and the Engineering Manager.

If the material is deemed scrap, material must be so identified with a tag and be put in a controlled area and the customer notified.
