涂装工序 PFMEA 案例Painting Process PFMEA Case Study

涂装工序链长、变量多，常常写成「漆面不好看」这类空话。这份案例把起泡脱落、颗粒异物、流挂、色差、桔皮五类典型失效逐一拆解，原因追到前处理、喷涂参数、烘烤曲线，是涂装车间做 PFMEA 的实战参照。Painting lines are long and rich in variables, so PFMEA easily degrades into remarks that the paint simply does not look good. This case breaks five typical failures - blistering and peeling, foreign particles, sagging, color difference and orange peel - into root causes down to pretreatment, spraying parameters and baking curves, making it a practical reference for painting PFMEA.

涂装 PFMEA 别只写"漆面不好看"：五种典型失效模式追到参数层Stop Writing "Paint Looks Bad" in Your PFMEA: Five Typical Painting Failure Modes Traced to Process Parameters

涂装工序链长、变量多，PFMEA 写成"漆面不好看"等于白做。按"后果—原因—现行控制"拆解起泡脱落、颗粒异物、流挂、色差、桔皮五种典型失效模式，把失效原因追到工艺参数层面，让 PFMEA 真正落地。A painting PFMEA that just says "paint looks bad" is wasted effort. This article breaks down five typical failure modes — blistering/delamination, particles, runs, color mismatch and orange peel — by effect, cause and current controls, tracing every cause down to process parameters.

焊接工序 PFMEA 案例Welding Process PFMEA Case Study

面向汽车车身与底盘焊接工序的 PFMEA 案例表，把虚焊、焊穿、气孔、变形等典型失效按「后果—原因—现行控制」拆开，失效原因落到电流、电压、焊接时间、夹具定位等可调参数上，可直接作为车间编写 PFMEA 的参照底稿。A PFMEA case form for automotive body and chassis welding stations, breaking typical failures such as weak welding, burn-through, porosity and deformation down into effect, cause and current control. Failure causes are traced to adjustable parameters like current, voltage, weld time and fixture positioning, so it works directly as a reference draft for shop-floor PFMEA.

汽车座椅 PFMEA 案例Automotive Seat PFMEA Case Study

座椅总成涉及骨架、发泡、面套、滑轨与电装多个子系统，PFMEA 容易漏项。这份案例按子系统组织失效分析，把异响、调节卡滞、强度不足、面套脱线等问题追到具体工序与参数，适合座椅厂工艺、质量工程师作为编写模板。Seat assemblies involve frame, foam, trim, rails and electrical components, which makes PFMEA items easy to miss. This case organizes failure analysis by subsystem, tracing issues such as abnormal noise, stiff adjustment, insufficient strength and trim detachment down to specific operations and parameters, making it a usable writing template for seat plant process and quality engineers.
