22、 Zielnicki, Richard Crisp9-Jan-20122. Introduction2.1Purpose/Objective2.1.1PurposeProduct cosmetics include the visual, auditory and tactile qualities which directly affect aesthetic satisfaction. In a marketplace where first impressions and perceived images heavily influence product acceptance, the

23、 appearance of a product can deliver the promise of excellence in performance and functionality. Attention to detail on the outside of the product sends an important message to the customer about total commitment from the company behind that product. Through high-quality, consistent product cosmetic

24、s, Dell can reinforce its dedication to long-term customer satisfaction. This document provides the cosmetic standards for use by Dell offices worldwide to maintain its competitive position while meeting its customers needs and expectations. 2.1.2Objective1. To provide a quantifiable baseline for ju

25、dging cosmetic quality. 2. To provide a baseline for cosmetic level brand differentiation. 3. To provide a baseline for cost estimates by the Product Group, Production Engineering and Field Service.4. To provide an acceptance criteria baseline for Purchasing to secure bids and contracts.5. To provid

26、e an acceptance criteria baseline for Suppliers, Production Engineering and Incoming Quality.2.2ScopeThis document is intended for worldwide use by Dell Business Units (Marketing, Product Group, Purchasing, Production Engineering, Manufacturing, Quality and Field Service) and associated suppliers. T

27、hese standards are provided to facilitate consistency in the communication and resolution of cosmetic related issues.2.3ReferencesThe following documents may be used as references in regard to color specification. Color specifications, (see Color Document example in Appendix F), may expand on certai

28、n aspects of the test methods and supersede the documents listed below.

Document RequirementsThis specification identifies and defines two key document types. 3.1Product Specific Cosmetic Specification (PSCS)

34、or ESG (Enterprise Server Group - Servers and Storage) Product Design Language Guideline Document.All Dell non-ESG products that require deviation from or additional specification to the CCS require a PSCS document. All Dell ESG products that require deviation from or additional specification to the

35、 CCS require an ESG Product Design Language Guideline and / or a PSCS.The PSCS or ESG Product Design Language Guideline document details product-specific cosmetic information. The PSCS or ESG Product Design Language Guideline should contain assembly tolerances, definitions of unique cosmetic element

36、s, acceptable limits and any deviations from the CCS. Mechanical Engineering and Industrial Design are jointly responsible for creating the PSCS or ESG Product Design Language Guideline document. Each PSCS or ESG Product Design Language Guideline shall include, at a minimum, the following sections:1

37、. Purpose & Scope (included in the Introduction paragraph)2. Visual Diagram & Inspection SummaryThis section should be focused, concise and contain all critical information.3. Reference Documents (included in the Introduction paragraph)When the inspector needs additional information beyond the Visua

38、l Diagram & Inspection Summary, the PSCS References Paragraph will provide the specific additional information pertaining to the product. Reference documents may include Dell Corporate Cosmetic Specifications or other industry standards as applicable.When conflicts arise between the CCS & PSCS or ES

39、G Product Language Design Guideline Document, see Section 7.0 Conflict Resolution3.2Corporate Cosmetic Specification (CCS)The CCS document serves as a baseline for communicating cosmetic requirements for all Lines of Business, (LOB). Cosmetic specifications in this document are identified in separat

40、e sections for each of the following: Molded Plastic Sheet Metal Die Cast Painted/Coated Materials Labels/Printing/Silk Screening IMD Film Heat Transfer Film Defect Appraisal Color Dell Logo Chassis GapThe CCS is to be used as a basis for RFQ, initial design and ongoing quality criteria. Unless the

41、PSCS, drawings, or other specifications clearly state a different requirement, the CCS shall apply and be in effect.4. ApplicationThe use of the PSCS will minimize the time and effort required to bring a product to market by:1. Enabling Dell to call out on the PSCS only those items that vary from th

42、e CCS. 2. Providing Procurement with clear cosmetic requirements for communication to suppliers.3. Communicating cosmetic requirements earlier in the design phase to facilitate more accurate cost estimate.4. Defining requirements early in the design phase to help suppliers design and implement the n

43、ecessary processes to support key cosmetic requirements.5. Clearly establishing cosmetic requirements within the Product Features Guide6. Providing an easy reference for all engineering drawings that refer to a PSCS or the CCS.7. Providing supplemental ongoing quality requirements for the specific p

44、roduct.5. Maintenance5.1PSCSChanges to the PSCSs must occur under ECO control and will require approval by designated document approval authorities.5.2CCSChanges to the CCS must occur under ECO control. The Dell Experience Design Group, (EDG), is responsible for reviewing the CCS as needed. Dell EDG

45、 shall update and maintain this Corporate Cosmetic Specification to reflect current market, industry and Dell practices. 6. Document Control and DistributionThe Corporate Cosmetic Specification (CCS) and the Product Specific Cosmetic Specifications (PSCS) will be placed under the Part Change Order (

46、ECO) control process. 6.1Document Number AssignmentThe PSCS shall be assigned a Dell “part number” through Agile.6.2DistributionThe documents will be published and posted in Agile. 7. Conflict ResolutionIf conflicts over cosmetic requirements arise between Dell and a Supplier, the final interpretati

47、on will be made by the PSCS owners or ESG Product Language Design Guideline Document owners with support from Dell Procurement and Dell Quality.When the 6724U Corporate Cosmetic Specification conflicts with the Product Specific Cosmetic Specification or ESG Product Language Design Guideline Document

48、, the Product Specific Cosmetic Specification or ESG Product Language Design Guideline Document shall always take precedence and override the CCS. Likewise, specific product design documentation for parts or assemblies (e.g. Level 5 assembly documentation) supersedes the 6724U CCS and the applicable

49、 PSCS or ESG Product Language Design Guideline Document.8. Molded PlasticThis paragraph will provide a uniform worldwide standard for the inspection of injection molded parts and assemblies. These guidelines will be used by Dell suppliers, as well as Dell personnel involved in first article inspecti

50、on, purchasing, incoming inspection, assembly, ongoing quality and final audits at all Dell and supplier manufacturing sites. The end goal is to provide Dell manufacturing sites and Dell suppliers with best-in-their-class components and assemblies.8.1Molded Plastic Defects Blush: Discoloration or ch

51、ange in gloss, usually at gate areas or where wall thickness changes. Bubbles: Transparent parts or void pockets (may appear as a blister or bulge on colored parts). Burns: Brown marks, spots or streaks (usually associated with poor venting of gasses during molding). Cold Slug: Visible inhomogeneous

52、 melt from the first material to enter the mold during injection. Contamination: Discoloration from foreign material or foreign material embedded in the surface. Cracking: Splitting or fissures causing separation of the material. Crazing: Tiny cracks or white marks that are visible due to stress exe

Drag Marks: Scratches from the plastic scraping against the mold during part ejection. Flow Marks: Directionally off-tone wavy or streaked appearance of a

54、surface. Flash: Excessive plastic along the parting line or mating surface of the mold. Gas Marks: Burn marks or dark discolored streaks usually caused by inadequate venting of the gasses trapped in the mold during the injection phase. Gouge: Surface imperfection due to abrasion, nicking or poor tri

55、mming. Grease: Machine lubrication on the part. Haze: Cloudiness of a transparent part. Marbling: Colored streaks due to incomplete mixing of color. Nicks: Surface scratches or indentations due to mis-handling of part. Particles: Small discolored spots or matter embedded in material. Pin Push: Distortion or protrusion caused by ejector pin pushing into part. Pitting: Crater-like imperfections in the material. Porosit
