Aluminum Die Casting DFM and RFQ Guide for Decorative Housing Projects
A professional checklist for ADC12 decorative aluminum housing projects, covering manufacturability review, RFQ inputs, tooling risks, process control and quality documentation.
Aluminum die casting DFM and RFQ guide for decorative housing projects, covering ADC12 material, wall thickness, draft angle, gate, overflow, vacuum, CNC, finish and PPAP documents.
DFM Review Scope
A decoration-oriented aluminum die casting RFQ should not only ask for unit price. It should verify whether the visible surface, thin wall, screw boss, ventilation hole and post-machining requirements can be produced consistently.
- Nominal wall thickness and local thick sections
- Draft angle, parting line and visible surface requirement
- Boss, rib and ventilation opening risk
- CNC machining allowance and datum strategy
RFQ Data Package
A complete RFQ package reduces quotation ambiguity and prevents mold-cost surprises after project kickoff.
- 2D drawing, 3D model and material grade
- Annual volume, batch size and target lead time
- Surface finish, color, coating and cosmetic standard
- Inspection report, FAI, PPAP or customer-specific documentation
Process Control Notes
Decorative housings need process control around filling, porosity, shrinkage, finishing and fixture deformation.
- Gate, overflow and venting proposal
- Vacuum or local exhaust requirement
- Trimming, deburring and CNC fixture plan
- Surface defect control before painting or powder coating
XSD treats decorative die casting housings as production engineering programs. Send drawings, finish requirements and inspection expectations before final quotation.
工程指南 / DFM 与 RFQ
铝合金压铸装饰外壳 DFM 与 RFQ 工程指南
面向 ADC12 装饰铝外壳项目的专业检查清单，覆盖可制造性审核、RFQ 输入、模具风险、过程控制与质量文件。
铝合金压铸装饰外壳 DFM 与 RFQ 工程指南，覆盖 ADC12 材料、壁厚、拔模角、浇口、溢流、真空、CNC、表面处理和 PPAP 文件。
DFM 审核范围
装饰性铝合金压铸外壳 RFQ 不应只询问单价，还应确认外观面、薄壁、螺丝柱、通风孔和后加工要求是否能够稳定量产。
- 名义壁厚与局部厚肉区域
- 拔模角、分型线和外观面要求
- 柱位、加强筋和通风孔风险
- CNC 加工余量与基准策略
RFQ 资料包
完整的 RFQ 资料能减少报价歧义，并避免项目启动后出现模具成本和交期偏差。
- 2D 图纸、3D 模型和材料牌号
- 年用量、批量大小和目标交期
- 表面处理、颜色、涂层和外观标准
- 检测报告、FAI、PPAP 或客户指定文件
过程控制要点
装饰外壳需要围绕充填、气孔、缩孔、表面处理和夹具变形进行过程控制。
- 浇口、溢流和排气方案
- 真空或局部排气要求
- 修边、去毛刺和 CNC 夹具方案
- 喷涂或粉末涂装前的表面缺陷控制
XSD 会把装饰性压铸外壳作为量产工程项目处理。最终报价前建议提供图纸、表面要求和检测文件要求。
