电视工艺与材料工程师
北京
社招
全职
职位 ID:A150140
职位描述
1. 新工艺、新材料预研
1)跟踪行业新技术:新型改性塑料、轻量化材料、新型表面工艺、低 VOC 胶黏剂;做预研样品、对比测试,输出预研报告,评估导入时机与成本收益。
2)技术沉淀:编写材料规范、工艺设计规范、DFM 设计指南,建设内部知识库,给结构设计师做培训。
2、材料选型、评估、替代、降本(材料主线)
1)依据产品定位(高端 / 中端 / 入门)、可靠性要求、成本目标,完成整机结构件材料选型:PC/ABS、HIPS、改性 PP、玻纤料、镁合金、冷轧钣金、铝型材、背光膜材、泡棉、双面胶、低 VOC 胶水、缓冲包装材料等。
2)开展材料性能验证:热变形、冲击、阻燃、耐候老化、CLTE 热膨胀、应力开裂、VOC、气味、耐化学(手汗、清洁剂),输出材料评估报告,建立整机材料规格库。
3)物料替代、降本项目:在保证可靠性前提下推动材料降级、国产替代、回收料应用;识别材料风险(蠕变、发黄、低温脆裂、高温 Mura 风险)。
4)失效分析:市场退回、试产不良,做材料层面根因定位:开裂、变形、发白、脱胶、掉漆、异响,输出对策(改牌号 / 改改性配方 / 切换供应商)。
3、工艺评估与 DFM 可制造性评审(工艺主线)
1)参与方案、3D 结构评审,从模具成型、装配、表面工艺角度输出 DFM 意见:壁厚、圆角、拔模、筋条、浇口位置、避免厚薄差、减少困气、双色注塑可行性、热压贴敷 / IML / 喷涂 / 蚀刻 LOGO 工艺可行性。
2)各类成型 & 表面工艺评估:注塑、双色注塑、压铸、钣金冲压、热压贴敷、模内装饰 IML、喷涂、UV、蚀刻、阳极氧化、烫印;评估良率风险、成本、外观良率边界,哪些结构可以做、哪些结构工艺实现不了。
3)模具对接:与模具厂协同,识别缩水、翘曲、熔接痕、气纹风险;针对大件电视后盖、中框,评估翘曲、热胀冷缩带来的屏体应力风险。
职位要求
高分子:ABS、PC/ABS、HIPS、改性 PP、玻纤增强料,注塑缺陷(翘曲、缩水、熔接痕、应力开裂);
金属:钣金、压铸镁铝,冲压、压铸常见缺陷;
