1、DFM 常用中英文对照15 、如果分型面此处，模具上会有尖角和刀口，对模具寿命有影响。There are sharp edges if we set the parting line here, it will reduce the tool life.16 、此处料厚段差很大，成品表面会有应力痕，建议修改如图示。The thickness is not equal and it will bring the stress lines on the surface, suggest to improve the part as the picture shown.17 、此大行位上有小行位，开
2、模时小行位需先退，大行位做延时，合模时则相反。The small slider is inside the big slider, when the mold open, the small slider need to recede first and the big slider have to postpone. When the mold close, it is contrary.18 、此处需做强顶。This position need to force ejection.19 、由于此处没有足够空间下热咀，所以需做一个柱子进胶。This position need to make
3、 a pole for gating because there have no enough space for hot sprue.20 、沾模，Stick1.High shrinkage values could indicate sink marks or voids at gate location 高缩水率的产品容易产生缩印，但在浇口附近可以避免。2.Welding line on the cosmetic surface 熔接线在外表面3. Two banana gate was to being confluent in the end of melt flow. 两个香蕉浇口
4、在流动未端熔合。4.Venting insert here has flash 排气镶件处有飞边5.Venting gap between inserts is too big镶件处的排气槽过大6.Stress mark on the cosmetic surface产品外表面上有压痕7. Uneven thickness 不平均的产品壁厚8.Unreasonable product structure 不合理的产品结构9.Injection speed is high注塑压力过高10.There is black spot on the cosmetic surface产品外表面上有黑色点1
5、1.There is flash on the product产品有飞边12.there is sink mark on the cosmetic surface产品外表面上有缩痕13.Gate size is not reasonably浇口尺寸不合理14. There is argent spot 这里有亮点 （银色斑点）15. The plastic of first shot didnt meet high temperature. 塑料的第一胶不会有很高的温度。16.Make sure the core float plate was closed before lifter com
6、pletely return to correct position确认 lifter 完全回位时 core 侧浮动板已经复位17.Make sure the ejector system is smooth 确认顶针系统移动平稳18.Add early return structure to protect lifter return to correct position增加先复位机构保护lifter 回到正确位置。19.Propose to add draft on slider side wall and draw polish. 建议增加slider 的角度和抛光角度。20.It i
7、s too thin and very difficult to inject fully, and weakness wall will have risk of the part function该处壁厚过薄而造成很难去填充完整，薄壁将会有产品功能上的风险。21.These are will have sink marks due to uneven thickness, propose to reduce plastic. 壁厚不均匀容易产生缩印， 建议在该处减胶。22.These are will have sink marks due to ribs opposite. 正面的筋位易
8、导致背面产生缩印。23.Please confirm the 3D part thickness whether has including painting thickness or not?请确认产品的设计是否考虑到油漆的厚度。24.Black paint on back side 。背面喷黑漆处理。1、这个红色面在前模方向 /后模方向 /行位方向有倒扣。This red surface is undercut at cavity side / core side / slider side.2、这些红色面在前模方向 /后模方向 /行位方向有倒扣。These red surfaces ar
9、e undercut at cavity side / core side / slider side.3、产品的这个位置太小，导致模具在前模方向/后模方向 / 行位方向有薄钢位。This position is too small and it will bring the thin steel at cavity side / core side / slider side.4、这些红色线是前后模 /镶件 /行位 / 斜顶分型线。These red lines are the parting line of cavity and core / insert / slider / lifte
10、r.5、此产品使用推板 /推块顶出。Use the stripper plate / ejector block to eject this part.6、前模 /后模斜内行位。Inner angle slider at cavity / core side.7 、为了简化模具结构建议改变此处出模方向。Suggest to change the draft direction of this position to make the mold structure simply.8 、最终的进胶位置根据模流分析。Finally gate position according the mold f
11、low analysis.25.Cosmetic issue 外表面问题26.Customer appointed material客户指定材料27.Increase the temperature for improving filling.增加温度来改善填充28.All of the fill patterns are unbalance所以的填充样板都不平衡？29.The part has hesitation effect and unbalance.产品有滞留和不平衡30.Bulk temperature is uniform.体积温度不平均31.The cycle time is
12、the same周期是同样的32.Shear rate is over the maximum value at the gate region 浇口区域的剪切速率已超出最大值33.Weld line is obviously on blue region. Advise to cut core insert to strengthen venting .蓝色区域有较明显的熔接线，建议做core 侧镶件来加强排气34.The areas highlighted in pink ball are the places where air traps maybe happen and sugges
13、t cutting insert to improve venting.粉红色球标示出的区域可能会有困气，建议割镶件改善排气。35.Average wall thickness is 0.50 only, Max is 0.74. It is too thin and very difficult to inject fully.产品均厚仅有 0.5mm，最厚为0.74mm, 产品整体壁厚太薄，很难成型饱满。36.Sharp edge shown in red circle, there may occur as flash or burr issue after painting proce
14、ss, it will impact to paint yield rate. 红色圆圈内的棱角在喷漆后有可能产生飞边现象，增加喷漆返工比率。37. Cutting by CNC after hard coating process. CNC 后需经热处理。38. Core side no any marks 后模无任何标记。To keep the sharp edge around the product, we can extend the skirt on outside, then cut it off by CNC after hard coating process.39. Keep some clearance on this face. 此面留铁40. Visible lines here, please confirm. 此处有熔接线，请确认。41.Sub insert for air vent 排气镶件42.Shut off 插穿 / Kiss off 碰穿43.Insert molding/ Family mold / Over mold嵌件模 /子母模 /包胶模44. General Parameters 普通参数45.
