class=\"wp-block-paragraph\">This is an important distinction that is often overlooked.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Channel depth<\/strong>&nbsp;is the physical depth of the sealing channel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Actual fill depth<\/strong>&nbsp;is how high the silicone gel actually fills during production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Por ejemplo:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Channel depth: 12 mm<\/li>\n\n\n\n<li>Actual gel fill depth: 9 mm<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the channel is intentionally not filled to its full depth, the calculation should use <strong>9 mm<\/strong>, not 12 mm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Using the full channel depth when the actual fill height is lower can significantly overestimate material consumption.<\/p>\n\n\n\n<p

Four Numbers You Should Not Confuse<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A useful way to manage silicone gel consumption is to separate four different

class=\"wp-block-paragraph\">This distinction is critical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a filter may theoretically require 288 g of gel, but the production line may consume 315 g per good filter because of equipment residue and start-up waste.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Theoretical

class=\"wp-block-heading\"><strong>How to Measure Actual Silicone Gel Consumption<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once production begins, actual consumption can be measured rather than estimated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, suppose a production run starts with:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>5.2 kg of

class=\"wp-block-paragraph\">For process optimization, it is useful to separately record:<\/p>\n\n\n\n<ol start=\"8461\" class=\"wp-block-list\">\n<li>Material loaded into the

<strong>illustrative planning assumption<\/strong>, but it should not be presented as an industry standard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For an established production line, the better

Consumption<\/strong><strong><\/strong><\/h2>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Using filter face dimensions<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">A 610 \u00d7 610 mm filter does not automatically have a specific gel requirement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Use the sealing-channel geometry.<\/strong><\/p>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li>Using full channel depth instead of actual fill depth<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">If the channel is 12 mm deep but only 9 mm is filled, use the actual 9 mm fill depth.<\/p>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li>Using the wrong density<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">The density used for weight conversion should correspond to the <strong>mixed silicone gel system<\/strong> being evaluated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not automatically use the density of Part A or Part B alone.<\/p>\n\n\n\n<ol start=\"4\" class=\"wp-block-list\">\n<li>Treating theoretical quantity as purchasing quantity<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Theoretical channel volume does not include mixer residue, priming, start-up waste or rejected filters.<\/p>\n\n\n\n<ol start=\"5\" class=\"wp-block-list\">\n<li>Applying a fixed industry loss percentage<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">There is no universal production-loss percentage for every filter manufacturer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Measure the actual process whenever possible.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How to Estimate Silicone Gel for a Trial Order<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For a new filter design, the most reliable approach is to work through three stages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Stage 1 \u2014 Engineering estimate<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Channel length<\/li>\n\n\n\n<li>Cross-sectional area<\/li>\n\n\n\n<li>Actual fill depth<\/li>\n\n\n\n<li>Mixed gel density<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This gives the theoretical requirement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Stage 2 \u2014 Controlled production trial<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Produce a known number of filters and record:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Material loaded<\/li>\n\n\n\n<li>Material dispensed<\/li>\n\n\n\n<li>Material remaining<\/li>\n\n\n\n<li>Good filters produced<\/li>\n\n\n\n<li>Rejected or reworked filters<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Stage 3 \u2014 Establish actual consumption<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Calculate:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Actual Production Consumption=Total Material Used\u00f7Good FiltersActual\\ Production\\ Consumption= Total\\ Material\\ Used \\div Good\\ Filters<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This number can then be used for future purchasing and production-cost calculations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are evaluating silicone as an alternative to polyurethane, see our detailed comparison of <strong>silicone gel vs polyurethane gel for<\/strong> <strong>HEPA<\/strong><strong>filtro<\/strong> <strong>sealing<\/strong> before finalizing the material trial.<\/p>\n\n\n\n<p
