shrinkage, wall flexibility, transparency and the required reading method. Equal vertical spacing does not always represent equal volume increments on a tapered or curved container. Buyers should define whether the marks are reference indicators or verified volume marks and approve them using molded samples before mass production.<\/p>\n<p data-start=\"1845\"

data-start=\"4527\" data-end=\"4581\">But many silicone products are not straight cylinders.<\/p>\n<p data-start=\"4583\" data-end=\"4615\">A silicone breast pump may have:<\/p>\n<ul

case, 20 ml of additional liquid may not raise the liquid level by the same height at every part of the container.<\/p>\n<p data-start=\"4838\" data-end=\"4848\">Therefore:<\/p>\n<p data-start=\"4850\" data-end=\"4939\"><strong data-start=\"4850\" data-end=\"4939\">Equal volume increments do not necessarily mean equal vertical spacing between marks.<\/strong><\/p>\n<p

Measuring Marks Be Molded Directly Into Silicone?<\/h3>\n<p data-start=\"14811\" data-end=\"14815\">Yes.<\/p>\n<p data-start=\"14817\" data-end=\"14912\">Embossed or debossed scale marks can be integrated into the mold when the geometry is suitable.<\/p>\n<h3 data-section-id=\"15imygm\" data-start=\"14914\" data-end=\"14961\">Are 20 ml Increments Always Equally Spaced?<\/h3>\n<p data-start=\"14963\" data-end=\"14966\">\u305d\u3046\u3060\u3002<\/p>\n<p data-start=\"14968\" data-end=\"15082\">If the internal cross-section changes with height, equal-volume increments may require different vertical spacing.<\/p>\n<h3 data-section-id=\"1ay4tuv\" data-start=\"15084\" data-end=\"15139\">Are Printed Marks Easier to Read Than Molded Marks?<\/h3>\n<p data-start=\"15141\" data-end=\"15260\">They can provide stronger contrast, but printing introduces additional adhesion, alignment and durability requirements.<\/p>\n<h3 data-section-id=\"12qzavl\" data-start=\"15262\" data-end=\"15310\">Does Silicone Shrinkage Change the Capacity?<\/h3>\n<p data-start=\"15312\" data-end=\"15440\">Dimensional change can affect the finished internal geometry, which is why capacity should be verified on actual molded samples.<\/p>\n<h3 data-section-id=\"1eekzza\" data-start=\"15442\" data-end=\"15503\">Can a Flexible Silicone Container Be Measured Accurately?<\/h3>\n<p data-start=\"15505\" data-end=\"15601\">It can be evaluated repeatably when the product condition, position and test method are defined.<\/p>\n<h3 data-section-id=\"1anpb7m\" data-start=\"15603\" data-end=\"15655\">Should Capacity Be Checked on Every Mold Cavity?<\/h3>\n<p data-start=\"15657\" data-end=\"15774\">Critical capacity or mark-position requirements should be evaluated across active cavities during mold qualification.<\/p>\n<h3 data-section-id=\"11fftke\" data-start=\"15776\" data-end=\"15832\">Can the Scale Be Changed After the Mold Is Finished?<\/h3>\n<p data-start=\"15834\" data-end=\"15971\">Printed artwork may be easier to change than mold-integrated marks.
