【摘要】 通过有限元模拟热模压成形中的脱模过程,分析了一般脱模工艺造成图形缺陷的原因;通过优化脱模工艺过程,采用低表面能的聚四氟乙烯作为抗粘剂,减小脱模时的摩擦,获得了高质量的模压复制品。更多还原

【Abstract】 Finite Elements Method (FEM) was adopted to analyze the demolding behavior using ABAQUS/Stan-dard. Some causes which lead to typical defects were identified. To minimize the friction force an optimized experiment was performed using PTFE (Teflon)-sputtered mold inserts, which lowered the surface adhesion force. Typical defects like pull - up and damaged edges can be reduced.更多还原
