material flexibility, wall thickness, mold structure, shrinkage and the actual measurement method. Buyers should not apply one tight tolerance to every dimension. Critical sealing, assembly, capacity and fit dimensions require controlled inspection, while flexible non-functional areas may need more practical limits and clearly defined measuring

different inspectors may position the same flexible product differently.<\/p>\n<p data-start=\"7791\" data-end=\"7815\">Possible datums include:<\/p>\n<ul data-start=\"7817\" data-end=\"7925\">\n<li

Same Tolerance Be Applied to Every Silicone Dimension?<\/h3>\n<p data-start=\"12850\" data-end=\"12853\">\u041d\u0435\u0442.<\/p>\n<p data-start=\"12855\" data-end=\"12977\">Critical functional dimensions and flexible non-functional dimensions should normally have different control requirements.<\/p>\n<h3 data-section-id=\"14gefqp\" data-start=\"12979\" data-end=\"13028\">Why Do Buyer and Factory Measurements Differ?<\/h3>\n<p data-start=\"13030\" data-end=\"13162\">Possible causes include product positioning, caliper pressure, temperature, recovery time, datum selection and measurement location.<\/p>\n<p data-start=\"13164\" data-end=\"13227\">Both parties should use the same documented measurement method.<\/p>\n<h3 data-section-id=\"i0tsgs\" data-start=\"13229\" data-end=\"13284\">Can Silicone Be Measured Immediately After Molding?<\/h3>\n<p data-start=\"13286\" data-end=\"13379\">The approved inspection procedure should define when the product is stable enough to measure.<\/p>\n<p data-start=\"13381\" data-end=\"13449\">Immediate measurement may not represent the final product condition.<\/p>\n<h3 data-section-id=\"12h53x9\" data-start=\"13451\" data-end=\"13506\">Is a Caliper Suitable for Every Silicone Dimension?<\/h3>\n<p data-start=\"13508\" data-end=\"13511\">\u041d\u0435\u0442.<\/p>\n<p data-start=\"13513\" data-end=\"13651\">A caliper may compress or stretch very soft structures. Fixtures, gauges, optical inspection or functional fit tests may be more suitable.<\/p>\n<h3 data-section-id=\"hpkey4\" data-start=\"13653\" data-end=\"13694\">Should Every Mold Cavity Be Measured?<\/h3>\n<p data-start=\"13696\" data-end=\"13810\">Yes, critical dimensions should be checked across every mold cavity during mold qualification or pilot production.<\/p>\n<h3 data-section-id=\"pmonx7\" data-start=\"13812\" data-end=\"13877\">Can Packaging Cause a Product to Fail Dimensional Inspection?<\/h3>\n<p data-start=\"13879\" data-end=\"13883\">Yes.<\/p>\n<p data-start=\"13885\" data-end=\"13973\">Folding and compression can temporarily or permanently change flexible product geometry.<\/p>\n<h3 data-section-id=\"z5e5m3\" data-start=\"13975\" data-end=\"14038\">Does Higher Silicone Hardness Improve Dimensional Accuracy?<\/h3>\n<p data-start=\"14040\" data-end=\"14151\">Higher hardness may improve shape stability, but it can also change folding, suction, sealing and user comfort.<\/p>\n<p data-start=\"14153\" data-end=\"14233\">Hardness should not be changed without evaluating the complete product function.<\/p>\n<hr

data-end=\"14424\">A dimensional tolerance is useful only when the product condition, datum, equipment and measurement method are clearly defined.<\/p>\n<p data-start=\"14426\"
