How to use the plastic dimension tolerance query--(GB-14486 China standard)

the plastic dimension tolerance query link below, 

https://www.hky-technik.com/Calculation_tool/plastic_part_tolerance_query_tool/tolerance_query.html

point this link, then you can see the interface link the image above, 


1,  you can select the language that you are familiar with, this webpage offer 7 languages,
China, English,Русский, Deutsch, Français, Español,Português.
2, select the tolerance standard of the GB_14486
3, choose the plastic Material, 
4,  input the length.(the maximum length is 180mm)
5, choose "dimensions with indicated tolerance" or "dimensions without indicated tolerance" 
6, choose "hight precision" or "general precision"
7. choose "A" or "B"
8, Usually, you don't need to change anything, the query sheet can be according you choose the material and the precision to choose.Mark class A: outer overall dimensions of the product, inner-hole diameters, distances between two concentric bosses or posts, etc. (directly determined by the cavity/core). Mark class B: step heights at the parting surface, dimensions formed by side actions/sliders, depth accuracy, etc. (affected by mould fitting and matching).
9, click this button,
10, The search results will appear here for you.

PL Balance block area calculation formula link: https://www.hky-technik.com/Calculation_tool/PL%20Balance%20block%20area%20calculation%20formula/PL%20Balance%20block%20area%20calculation%20formula.html 1. Ensuring Mold Clamping Accuracy - Uniform distribution of clamping force: Support blocks ensure that the movable half and fixed half of the mold remain parallel during mold closing, preventing localized gaps. - Prevention of platen deformation: Under high injection pressure, support blocks bear part of the clamping force, protecting the mold plates from bending or deformation. - Extended mold service life: They reduce abnormal wear on mold plates, guide pillars, and guide bushes. 2. Optimizing Mold Structure - Supporting function: Support blocks provide additional support in the central area of the mold, especially for large molds. - Positioning assistance: Used together with guide pillars, they improve alignment accuracy during mold closing. - Adjustment function: By replacing suppor...

How to quickly evaluate product surface shrinkage using 3D software

Image
 How to quickly evaluate product surface shrinkage using 3D software UGNX: 1,   Select the check wall thickness command: the part normal thickness is 2.56mm you can move you mouse to the reddest areas to measure the largest thickness, but if you Change the part display mode to wireframe, you can see a ball,  this is the software creating that this area can be built largest ball into this. then  how do we determine whether this areas will show sink marks?   ∅E ≤ 1.18A. If this area is close to the gate, the meaning the flow length ratio is relatively small, this ∅E value can be further increased. 2.56mm*1.18=3.02mm<3.10mm  so we can think this areas will be show a bit sink mark. #sink #mark #injection #molding #defect, #plastic #part #cosmetic #defect, #design #plastic #product #standard, #DFM, #technique Best regards, Maggie ShenZhen HuaKaiYu Technology Co, Ltd.  Mobile / Whatsapp/ Wechat /Teams :0086 15920030230 https://www.hky-technik.co...
