1.0 Operating Procedure

1.1 Process and Inspection Traveler

The traveler is the primary record to ensure that each process and inspection occurs. All operations necessary in order to comply with the customer requirements shall be included on the traveler. Upon completion of each operational sequence, the operator shall initial that the appropriate operation has been completed and dated. If there is an accepted or reject criteria the operator/inspector shall record the quantities accepted or rejected and initial and ate in the designated location on the traveler. Any supporting documentation such as drawings or in-house prices procedures will accompany the traveler and shall become a permanent part of the traveler. At the completion of processing the completed traveler and all supporting documents shall be reviewed by Quality Assurance for total contract compliance. Upon Quality Assurance’s acceptance all completed documents will be maintained or dispersed per purchase order or contract requirements. The completed documentation shall be stored in a controlled area for five years or as required by contract.

1.2 Receiving Inspection

All parts received by Metal Preparations Inc shall go through a receiving inspection process to ensure that the purchase order quantities and the correct part numbers match the parts. There will also be a visual inspection performed to verify that all parts were received undamaged. The number of parts received and any comments as to the condition of parts received shall be entered on the traveler.

1.3 In-Process Inspection

The traveler is released by quality assurance for all customers supplied processes; therefore, the traveler will have all approved in process inspection along with the total operation process. The process inspections are to ensure uniformity of processes and compliance to quality requirements. Random process inspections will be imposed when considered necessary. The quality inspector will notify the supervisor of the area when an in process inspection has resulted in a rejected item. All rejected items will be withheld from final processing, identified and processed in accordance with applicable procedures.

1.4 Final Inspection

Final Inspection shall be identified on the traveler and is utilized for the purpose of ensuring the conformance of parts to specification and contract requirements. All applicable coupons, customer required information and packaging requirements are also verified at the final inspection point.

2.0 Part Handling and Packaging

For all parts receiving a cleaning process avoid skin contact with the parts to prevent oxidation. If the parts have to be manually moved use lint free gloves. All parts shall be packaged per customer requirement/contract.

3.0 Non-Conforming Materials

All rejected units are segregated from acceptable units at the time of each inspection. The rejected units are recycled through the process until the parts conform to the specifications or contract requirement. If parts cannot be brought within specification or contract requirement the parts are packaged, identified as rejects and returned to the customer for disposition or rejects are handled per customer requirements.

4.0 Document Control

4.1 Internal Document Control

All documents prepared by Metal Preparations Inc shall be deemed internal documents. The control of the change of internal documents will be the responsibility of Quality Assurance. Anyone within the company can recommend a document change; however, only Quality Assurance can approve all recommended changes. All changes to documents will be assigned a revision letter and will be maintained in a permanent document file. All documentation will be distributed to appropriate work areas and the latest revision maintained in the work areas.

4.2 External document Control

All documentation supplied to Metal Preparations Inc by a customer or supplier shall be considered as external documents. All external documentation will be reviewed by Quality Assurance and Operations to determine the impact that the proposed operation may have on existing tooling, procedures, processes, inspections and cost. After review, a copy of the document is attached to each traveler that is affected by the contract. Upon completion of the contract all documentation will be filed unless requested by the customer representative to be returned to the customer. All supplier documentation will be maintained until the documentation has no impact on the operation.

5.0 Maintenance/Preventative Maintenance

Maintenance is performed on equipment as soon as an available technician can make the repairs. An inventory will be maintained on repair parts deemed critical or if parts are immediately available inventory is not required. All repair maintenance will be reviewed by Quality Assurance to ensure that equipment reliability is maintained. A preventative maintenance schedule will be maintained by Operations and this schedule will coincide with the calibration intervals in order to minimize equipment down time. The preventative maintanence schedule will be monitored by Quality Assurance for compliance.

6.0 Equipment Calibration Control

Equipment calibration shall be under the control of Quality Assurance with all history files for calibration being maintained by Quality Assurance.

7.0 Training

All training of personnel will be on the job Training which will last until the individual is determined to be effective and proficient in his or her job as determined by the operations manager. When considered to be necessary the Operation Manager and the Quality Assurance Manager will establish a training program. All discrepancy, rejected product and other noted deficiencies shall be monitored by the Quality Assurance Manager for Areas of the operation that may need retraining or remedial training.
