摘要
本文对车载注塑件熔接痕的预防,作出了设计-制造全流程的防控和优化改善对策。设计阶段要优化产品结构,减少导致熔接痕的结构;调整受力结构位置,使熔接痕对产品零件强度影响降低;合理选用材料,降低因材料流动性差导致的熔接强度降低问题。模具设计阶段根据产品零件设计强度、外观要求针对性制定改善策略;生产制造阶段对充分的成型参数摸排和详尽严格的过程管理,做到不产生、不流出不良品。从而对影响车载注塑件外观和强度质量的熔接痕问题进行有效地优化。
This paper proposes comprehensive prevention and optimization measures for weld lines in automotive injection-molded parts,covering the entire design-manufacturing process.Design stage:Optimize product structure to minimize features that induce weld lines;adjust load-bearing structure placement to reduce their impact on part strength;and select appropriate materials to mitigate weld line weakening caused by poor flowability.Mold design stage:Develop targeted improvement strategies based on part strength requirements and aesthetic standards.Production stage:Conduct thorough molding parameter testing and implement strict process control to prevent defects and ensure non-conforming products are not passed on.These measures effectively optimize weld line issues affecting the appearance and strength quality of automotive injection-molded parts.
