要保证最终产品质量,就要从原材料、电子元器件、外购件的质量抓起。南京晨光机器厂正是这样做的。为确保物资质量,该厂制定了《外购器材质量控制》、《新试制材料的质量控制规则》、《常用金属材料复验规定》,《非金属材料复验规定》、《金属材料的技术保管制度》、《合格器材供应单位的评价 To ensure the quality of the final product, we must start with the quality of raw materials, electronic components, and purchased parts. Nanjing Chenguang Machine Factory did exactly that. In order to ensure the quality of materials, the plant has established the “Quality Control of Outsourced Equipment”, “Quality Control Rules for New Trial Materials”, “Regulations for Re-inspection of Commonly Used Metallic Materials”, “Regulations for Re-inspection of Non-metallic Materials” and “Technology of Metal Materials”. “Custody System” and “Evaluation of Qualified Equipment Suppliers”
