VP- 004 Production and Service Part Approval

Purpose: “…The purpose of this Visteon Production and Service Part Approval Process (PPAP) procedure is to document the steps to achieve approval for the initial shipment of new or changed production parts. This process is to ensure that all engineering design andspecification, and A.I.A.G PPAP Manual requirements are met, and that the process has the potential to produce product that consistently meets these requirements, during normal production, at the stated production rate. This applies to PPAP from Visteon to their customers and to PPAP between Visteon plants…”

The following are typicalinputs to the Production Part Approval Process. There are other possible inputs described in the A.I.A.G. PPAP Manual. a) The release of a new or changed service or production part (part number) is the most common event that starts the PPAP process. This is usually started with an electronic document: WERS or SREA. This may be the release of a completely new part number or release of an existing basepart with a new part number suffix. The Engineering Change Management (ECM) process may output a document that initiates a Production Part Approval Process. b) A Statement Of Work is a description of the work (or deliverables) that Visteon agrees to provide as part of a contract with a customer. (Annual Layout).

c) Othercustomer specific requirements may start the process within Visteon. Customers who do not recognize the A.I.A.G. requirements may require different forms, methods, or approvals, prior to granting permission for initial shipment. These requirements should be described in the Statement Of Work. d) Change of the location of a process (process flow) may also require a submission warrant. If there is noeffect on the form, fit or function, resulting from the change in location, the activity may request a waiver of PPAP submission by the customer. Otherwise, PPAP will be required. Note: Sub-suppliers of components and parts must conform to all requirements of the end-item customer.

Submission Parts
2.4.1 Production parts (end-items)submitted for PPAP must be from a significant production run. Significant production runs are defined as between one and eight hours, producing a minimum of 300 consecutive pieces. Customer authorization must be obtained when this requirement cannot be met. 2.4.2 Manufacture parts for submission at the normal production site. Use the production tooling, gaging, process, materials, and operators,which constitute the production environment. 2.4.3 Parts from each unique production process, e.g. duplicate production lines, machines, cavities, etc., must be measured and representative parts tested.

Some customers may permit phasing in full production volume to coincide with the customer’s ramp up schedule for their ownproduction. For example, under some circumstances, Ford Motor Company permits a “Phased PPAP” process. One example of a situation in which PPAP may not be required is a Visteon manufacturing location, which is changing back to a sub-supplier that had previously been approved. The Visteon location may submit a request to the customer to waive PPAP and the customer may approve the request.

OBSERVATIONS:
- A “significant production run” consists of a minimum of 300 parts at normal production rate, unless the customer approves a different quantity or production rate. - Retain documents as they are generated during the run. - Approval of PPAP requires completion of all statistical studies as required in the pre-launch Control...
