Success Story
国光电器成立于1951年，以声学为核心技术，专注音响及电声元器件设计、制造和销售。客户反应在产品前期模拟分析时，第二射模拟结果显示内外圈黑色件流动平衡，但实际试模后，内外圈黑色件流动平衡差异大，内圈先填充满，外圈还有1/3未填充满，当外圈勉强填满时，内圈就会产生溢胶，披风。
利用 Autodesk Moldflow 模流分析软件，对产品进行模拟分析，使产品的内外圈要保持填充平衡，每穴需要同时到达填充末端。
根据第一次客供产品+流道模具3D设计图，导入 Autodesk Moldflow 模流软件后，进行全3D网格划分，参考客供成型参数，采用螺杆曲线控制填充方式进行模拟分析，结果显示内圈先于外圈填满，但相对客供实际短射件，模拟外圈流动相对实际还是过快一些；另外，客户再次反馈，实际加工流道尺寸跟第一次提供的模具设计尺寸有差异，实际个别流道加工尺寸比设计数大约1mm。由于实际流道尺寸参数与设计数误差较大，随后采用实际流道尺寸3D模型再次进行对比分析，该结果与实际短射件效果更接近。经过成型参数及3D流道尺寸优化后，还原出实际样件填充效果，再在该模型基础上，将中间圈的竖流道点浇口尺寸由原始的2mm改成1.2mm，分析出的结果显示内外圈填充基本平衡，内圈仍稍快一些。 考虑到模拟分析可能存在些许差异，以及考虑到加工修复问题，最终客户决定采用1.1mm的进胶大小进行改模。
通过 Autodesk Moldflow 软件模拟分析，帮助用户通过浇口改模后再次试模，样件内外圈流动短射结果跟分析结果相似，填充几乎平衡，最终样件质量满足了客户要求。
在产品尺寸较小，约∅70mm，内外圈壁厚差异较大，流道重量占比约63%，又为多腔模的条件下，在利用 Autodesk Moldflow 软件做前期分析时需要采用3D网格分析流动平衡（实际客户模流工程师采用的是Beam流道分析），所以选择正确的网格类型是关键。
当实际问题发生，要做问题还原时，材料，成型工艺需与实际保持一致，3D模型尺寸需与实际加工尺寸为依据进行网格建模，确保尽量少的变量因素出现，模拟出的结果才更易还原出实际状态。然后在还原出实际状态的方案基础上，再对相应问题进行改善，此时的改善方案才更可靠。

对供应商提供的moldflow分析报告进行有效管控并形成自己的Know-How数据库
与用户交流后发现，用户和下游的产品供应商和模具厂提供的仿真分析报告质量参差不齐；报告中的评判标准不一致，没有形成 know-how 数据库，没办法进行闭环，不能很好利用以往的数据 进行产品和模具设计的优化。
使用PowerMill高效加工帮助客户提高生产效率和品质
用户是一家专业生产汽车精密模具的企业，用户目前在加工大型或者复杂模具时面临着编程效率慢，安全系数低，加工产品的精度和质量较低，如何合理利用三轴和五轴机床提高加工效率等问题。
使用Alias快速建模帮助客户缩短开发周期
客户是一家历史悠久的国内大型车企，近年来随着其他同行业车企的不断更新换代，同质化竞争非常激烈。面对新能源汽车客户更加多样的个性化需求，要求该客户新车型更新换代的速度要赶上甚至超越对标车企，达到原车型开发速度的2倍以上，才有可能留住大量的年轻用户、保持住客户的行业地位。在以往的研发环节，客户还是延续以往汽车造型的传统流程，从概念到油泥需要两个月以上，在新车型造型设计阶段远远落后于对标企业。
