Abstract: Xenon lamp aging and ultraviolet light aging are commonly used light aging test methods to
evaluate the durability and lifespan of materials. These experiments can guide the design and production of
materials, ensuring product quality. However, there is currently a lack of data on the performance changes
of PA66 materials under light aging. This article takes PA66 material prepared by injection molding method
as the research object, and conducts light aging tests in UV aging test chamber and xenon lamp aging test
chamber, comparing and analyzing the changes in mechanical properties of the material after aging under
different types of light. The results showed that after 672 h of xenon lamp aging test, the tensile strength of
PA66 material decreased by 6.87% and the impact strength decreased by 10.45%; After 672 h of UV aging
test, the tensile strength of PA66 material decreased by 8.61% and the impact strength decreased by 14.55%.
It can be seen that the aging rate of ultraviolet light is higher than that of xenon lamp. Therefore, when using
PA66 material, direct sunlight should be avoided to prevent a decrease in its mechanical properties.
Key words: PA66; tensile strength; impact strength; aging test

数字孪生与 MES 系统第二次标准起草组工作会议顺利召开
The second working meeting of the standard drafting group for digital twins
and MES systems was successfully held

2025 年 7 月 30 日，中国塑料机械工业协会团体标准委员会以视频形式召开了《橡胶塑料注射成型机数字孪
生 第 1 部分 ：通用条件》和《注塑成型车间智能制造执行系统 (MES)》两项团体标准的第二次起草组工作会议。
会议由中国塑料机械工业协会常务副会长兼团体标准委员会秘书长粟东平主持，分为上午、下午两场，分别围绕“数
字孪生”与“MES 系统”两项标准的技术细节展开深入研讨，并顺利完成各项议程。
上午会议聚焦《橡胶塑料注射成型机数字孪生第 1 部分 ：通用条件》。宁波海天智联科技有限公司总监阎伟
主持讨论环节，并对标准进行解读。会议逐条讨论了 55 条专家反馈意见，重点对数字实体、可视化要求、故障
诊断等关键条款进行了修订完善。会上，专家们进一步细化了注塑成型机专用要求，确保标准的前瞻性与可操作性。
下午会议围绕《注塑成型车间智能制造执行系统 (MES)》展开，由博创智能装备股份有限公司和广州中和互
联网技术有限公司技术总监陈明治主持讨论环节，并对标准进行解读。会议对标准文本进行了逐章逐节梳理，重
点完善了 MES 功能架构、业务流程图、质量管理、数据存储、接口规范等内容。专家们就安灯管理、订单排产、
物料防错验证等关键指标达成一致意见。
会议完成了第二轮技术内容修订，后续牵头单位将于 10 个工作日内形成征求意见稿。中国塑料机械工业协
会对参与本次会议的全体专家表示衷心感谢，并诚挚邀请各单位继续关注标准后续进展，共同推动我国塑料机械
行业智能制造与数字孪生技术的标准化进程。
