For custom silicone products, first article inspection is not simply a visual check of one attractive sample. It should act as a production-release checkpoint that confirms the factory is manufacturing the correct revision under the intended production conditions.<\/p>\n<p data-start=\"1770\" data-end=\"1848\">A silicone sample may already have been approved weeks before mass production.<\/p>\n<p data-start=\"1850\" data-end=\"1898\">So why inspect the first production parts again?<\/p>\n<p data-start=\"1900\" data-end=\"1990\">Because several things may have changed between prototype approval and the production run:<\/p>\n<ul data-start=\"1992\" data-end=\"2307\">\n<li data-section-id=\"1bkfex0\" data-start=\"1992\" data-end=\"2025\">The mold may have been adjusted<\/li>\n<li data-section-id=\"1ti67dr\" data-start=\"2026\" data-end=\"2071\">Production cavities may now be fully active<\/li>\n<li data-section-id=\"n5ti7y\" data-start=\"2072\" data-end=\"2116\">Material or color batches may be different<\/li>\n<li data-section-id=\"13eo4it\" data-start=\"2117\"

data-start=\"2186\" data-end=\"2235\">The latest drawing revision may contain updates<\/li>\n<li data-section-id=\"90p4bb\" data-start=\"2236\" data-end=\"2307\">Production staff may be using a different setup from the sample stage<\/li>\n<\/ul>\n<p data-start=\"2309\" data-end=\"2418\">The purpose of first article inspection is to catch these differences before thousands of parts are produced.<\/p>\n<hr data-start=\"2420\" data-end=\"2423\" \/>\n<h2 data-section-id=\"wjraf6\" data-start=\"2425\" data-end=\"2490\"><span class=\"ez-toc-section\"

data-start=\"2492\" data-end=\"2542\">In consumer silicone manufacturing, terms such as:<\/p>\n<ul data-start=\"2544\" data-end=\"2652\">\n<li data-section-id=\"7kj4ko\" data-start=\"2544\"

data-end=\"2785\">For a typical OEM silicone project, the practical objective is similar:<\/p>\n<blockquote data-start=\"2787\" data-end=\"2957\">\n<p data-start=\"2789\" data-end=\"2957\">Confirm that the first parts made under intended production conditions meet the currently approved product requirements before releasing the order into full production.<\/p>\n<\/blockquote>\n<p data-start=\"2959\" data-end=\"3016\">It should not be confused with final shipment inspection.<\/p>\n<p data-start=\"3018\" data-end=\"3090\">First article inspection happens near the beginning of a production run.<\/p>\n<p data-start=\"3092\" data-end=\"3169\">Final inspection happens after the production lot has largely been completed.<\/p>\n<p data-start=\"3171\" data-end=\"3213\">The two

data-end=\"19172\">Is first article inspection required for every silicone order?<\/h3>\n<p data-start=\"19174\" data-end=\"19337\">Not necessarily in the same form. The level of inspection should depend on the project, customer requirements, tooling condition, product changes and quality risk.<\/p>\n<h3 data-section-id=\"bqrtte\" data-start=\"19339\" data-end=\"19400\">Is first article inspection only required for a new mold?<\/h3>\n<p data-start=\"19402\" data-end=\"19571\">No. It can also be useful after mold modification, long production interruptions, material changes, important engineering revisions or correction of a recurring problem.<\/p>\n<h3 data-section-id=\"1e16cdd\" data-start=\"19573\" data-end=\"19612\">Is one first article sample enough?<\/h3>\n<p data-start=\"19614\" data-end=\"19742\">It depends on the product and mold. For multi-cavity production, samples from different active cavities may need to be reviewed.<\/p>\n<h3 data-section-id=\"l3pz3a\" data-start=\"19744\" data-end=\"19791\">Should every drawing dimension be measured?<\/h3>\n<p data-start=\"19793\" data-end=\"19910\">Not always. Critical and function-related dimensions should receive priority according to the agreed inspection plan.<\/p>\n<h3 data-section-id=\"qlta4g\" data-start=\"19912\" data-end=\"19988\">Does passing first article inspection guarantee mass-production quality?<\/h3>\n<p data-start=\"19990\" data-end=\"20123\">No. It confirms the initial production setup against the agreed requirements. In-process and final quality controls are still needed.<\/p>\n<h3 data-section-id=\"1myv7cx\" data-start=\"20125\" data-end=\"20176\">Is a golden sample the same as a first article?<\/h3>\n<p data-start=\"20178\" data-end=\"20327\">No. A golden sample represents the approved target, while a first article verifies whether the current production process is reproducing that target.<\/p>\n<h3 data-section-id=\"18hkh7y\" data-start=\"20329\" data-end=\"20388\">Should packaging be included in first article approval?<\/h3>\n<p data-start=\"20390\" data-end=\"20518\">When packaging can affect shape, surface, fit or function, it should be validated using real production samples before shipment.<\/p>\n<hr data-start=\"20520\" data-end=\"20523\" \/>\n<h2 data-section-id=\"39qar5\"
