The Product May Be Evaluated Too Soon After Molding<\/h3>\n<p data-start=\"7184\" data-end=\"7276\">Flexible silicone should not automatically be judged at the first moment it leaves the

data-section-id=\"nwrxrj\" data-start=\"12830\" data-end=\"12872\">Does Softer Silicone Warp More Easily?<\/h3>\n<p data-start=\"12874\" data-end=\"12998\">It may be more flexible and therefore more sensitive to geometry and support, but hardness alone does not determine warping.<\/p>\n<p data-start=\"13000\" data-end=\"13116\">Wall thickness, overall size, texture and packaging must also be considered.<\/p>\n<h3 data-section-id=\"1pgk237\" data-start=\"13118\" data-end=\"13168\">Will Making the Product Thicker Solve Curling?<\/h3>\n<p data-start=\"13170\" data-end=\"13186\">Not necessarily.<\/p>\n<p data-start=\"13188\" data-end=\"13301\">Local reinforcement may help, but unnecessary thickness can change flexibility, weight, curing behavior and cost.<\/p>\n<p data-start=\"13303\" data-end=\"13345\">The complete structure should be reviewed.<\/p>\n<h3 data-section-id=\"hrlhhs\" data-start=\"13347\" data-end=\"13402\">Why Are Only the Corners of a Silicone Mat Curling?<\/h3>\n<p data-start=\"13404\" data-end=\"13532\">Possible causes include edge thickness, local stress, suction-cup layout, texture distribution, demolding or packaging pressure.<\/p>\n<p data-start=\"13534\" data-end=\"13605\">The mold and production samples should be compared by cavity and batch.<\/p>\n<h3 data-section-id=\"tdxzgb\" data-start=\"13607\" data-end=\"13645\">Can a Warped Silicone Mat Recover?<\/h3>\n<p data-start=\"13647\" data-end=\"13730\">Some deformation may be temporary, while other products may recover only partially.<\/p>\n<p data-start=\"13732\" data-end=\"13853\">The actual product should be evaluated using an agreed recovery test rather than assuming all deformation will disappear.<\/p>\n<h3 data-section-id=\"uvxti3\" data-start=\"13855\" data-end=\"13912\">Should Flatness Be Checked Before or After Packaging?<\/h3>\n<p data-start=\"13914\" data-end=\"13933\">Both can be useful.<\/p>\n<p data-start=\"13935\" data-end=\"14080\">Checking before packaging identifies molding-related deformation, while checking after packaged storage identifies packaging-related deformation.<\/p>\n<h3 data-section-id=\"j14czu\" data-start=\"14082\" data-end=\"14126\">Can More Suction Cups Fix a Curling Mat?<\/h3>\n<p data-start=\"14128\" data-end=\"14146\">Not automatically.<\/p>\n<p data-start=\"14148\" data-end=\"14338\">If the main mat is
