材料关注 / Material Focus
刚度与配合 / Stiffness & Fit
盒盖 / Lid
闭合配合 / Closing Fit
配合件，重点看边框结构、包边尺寸和合盖关系 / Mating part: frame, skirt size, and closing fit.
结构 / Structure
盒体和盒盖是配合件，既要单件稳定，也要整体闭合协调。 / The body and lid must be stable individually and coordinated as a set.
工艺 / Process
翻模加注塑既能复制外形，也能较稳定地保持装配关系。 / Mold duplication plus injection molding supports shape replication and stable assembly.
材料 / Material
材料要兼顾刚度、韧性和收缩稳定性，保证合盖顺畅。 / The material should balance stiffness, toughness, and shrinkage stability.
