4、vise the which the visible area is and the surface finish spec.MT11010 texture for red surface, please confirm.紅色面曬MT1101紋,請(qǐng)確認(rèn)Other surface apply Sandpaper 600# for mold release., please confirm.其它面省到600#砂紙出模,請(qǐng)確認(rèn)Draft Study _產(chǎn)品斜度分析Green surfaces without draft angle now, suggest to enlarge to 1 degre

5、e at least (by reduce material) Kindly advise.綠色面直身,建議最小減膠加1度斜度,請(qǐng)確認(rèn).Draft angle of the shut off surfaces (red marked) is not enough , least (by reduce material) it should be 3 degree at least.圖示紅色面擦穿，斜度不足（單邊最小3度）the red surface is straight, suggest add 3 draft angle on it (by reduce material) for te

6、xture MT0000, least (by reduce material), pls confirm. 紅色直身面,建議減膠加3度出模角來(lái)曬紋MT0000,請(qǐng)確認(rèn).Wall thickness study _產(chǎn)品壁厚分析Red area with uneven thickness, may cause sink marks, please help improve.紅色區(qū)域壁厚不平均,太厚了,可能縮水,請(qǐng)幫忙改善.Those ribs too thick, suggest thin them to 75% general part surface to avoid sink mark o

7、pposite it. Please confirm.箭頭所指骨位太厚,建議減薄到基本壁厚的75%來(lái)避免骨位對(duì)面縮水痕.請(qǐng)確認(rèn).Wall thickness well distribute.壁厚OK.Part tolerance study _產(chǎn)品公差合理性分析We did not get the part 2d drawing yet, would you please sent to us? Drawing with critical dimensions (tolerance) and note the criticalsurface will be great! 請(qǐng)?zhí)峁┌钆c高要求

8、表面的產(chǎn)品2D產(chǎn)品圖Provide information above before mold designing can help our engineer make the correct decision during design & manufacture, so we will get the perfect part and the lead time wouldnt be extended. Thank you!Tolerance here may too tight to injection, can it enlarge to +/- 0.2mm?這個(gè)公差太緊了,注塑很難保

9、證,是否可以加大到+/- 0.2mm?Warpage prevent _知悉客戶(hù)可能的產(chǎn)品變形Engraving & cav. N.O _產(chǎn)品曬字合理性分析與模穴號(hào)確認(rèn)Does this part need date wheel, recycle mark, or mark the part number?這個(gè)產(chǎn)品是否要加日期章/環(huán)保標(biāo)記/模穴號(hào)?Cav. Number here, text height 1.5mm raise 0.2mm,OK?在這里加模穴號(hào),字高1.5mm, 高出產(chǎn)品0.2mm,OK?Suggestion _產(chǎn)品結(jié)構(gòu)改善建議回復(fù)DFM的一般是客戶(hù)公司的產(chǎn)品工程師，他們大部分對(duì)模具并不熟悉，這就要求我們的模具工程師在做DFM時(shí)要考慮到這一點(diǎn)，提出的產(chǎn)品問(wèn)題應(yīng)盡可能給到量化的方案：如“骨位太厚，要減薄，請(qǐng)確認(rèn)”，這一句更好的表達(dá)應(yīng)該是“這條骨位太厚，可能導(dǎo)致產(chǎn)品表面有縮痕，建議減薄到根部1.2mm，請(qǐng)確認(rèn)。”標(biāo)準(zhǔn)的表達(dá)可以參考： 問(wèn)題+可能導(dǎo)致的后果+量化的解決方案。如：?jiǎn)栴}（骨位太厚）+可能導(dǎo)致的后果（表面有縮痕）+量化（根部1.2mm ）的解決方案（減薄根部）。更好的表達(dá)可以是：量化建議+可以解決的什么問(wèn)題。如：建議減薄到根部1.2mm，以防止產(chǎn)品表面有縮痕，請(qǐng)確認(rèn)。Suggestion
