(2).非标制件公差标准
ISO 3302-1为模制实心橡胶制件在固定尺寸和封闭尺寸方便建立了四个等级:
² M1级——精密模制零件的等级。这类模制零件需要精密的模具,较少的行腔,紧密的配合等等,这样会导致较高的成本。光学分析仪或其他类似的测量装置会被使用到,以在测量时将橡胶制品的变形减少到最小程度。这一类型的产品需要付出较高的监控成本。
² M2 级——高质量模制零件的等级,包括许多M1级中必须的精密控制。
² M3 级——良好模制零件等级
² M4 级——要求尺度并不严格的模制零件等级
上图中,F—固定尺寸。尺寸不会受到诸如飞边厚度或模具的不同部分(上模和下模或模芯)横向位移的影响。
C—封闭尺寸。尺寸会受到飞边或不同模具部分横向位移的变化而变化。
#—固定尺寸。范例高度尺寸,不受飞边厚度的影响,故被称为“固定”尺寸。
