href=\"https:\/\/www.lyasilicone.com\/de\/\"><strong>individuelle Silikonprodukte<\/strong><\/a> should be designed before tooling, especially for bath toys, feeding products, pet accessories and other products exposed to water or food. Buyers should review drainage-hole position, groove depth, internal cavities, removable structures, corner radius and drying orientation so that water and residue can be removed without creating unnecessary molding or durability problems.<\/p>\n<p class=\"isSelectedEnd\">A silicone product can look simple from the outside while containing structures that are difficult to rinse, drain or dry.<\/p>\n<p class=\"isSelectedEnd\">Typical problem areas include:<\/p>\n<ul data-spread=\"false\">\n<li>Deep narrow grooves<\/li>\n<li>Closed internal cavities<\/li>\n<li>Small water outlets<\/li>\n<li>Blind holes<\/li>\n<li>Deep embossed logos<\/li>\n<li>Complex suction structures<\/li>\n<li>Narrow channels<\/li>\n<li>Hollow handles<\/li>\n<li>Dense surface textures<\/li>\n<li>Areas where two components overlap<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">These details affect more than cleaning convenience.<\/p>\n<p class=\"isSelectedEnd\">They may also influence mold design, demolding, product durability, drying time, inspection and customer experience.<\/p>\n<p class=\"isSelectedEnd\">For OEM buyers, easy cleaning should therefore be treated as a product-design requirement rather than something considered only after the first sample is finished.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"Which_Silicone_Products_Need_Drainage_and_Cleanability_Review\"><\/span>Which Silicone Products Need Drainage and Cleanability Review?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Drainage is especially important for products that regularly contact:<\/p>\n<ul data-spread=\"false\">\n<li>Water<\/li>\n<li>Food<\/li>\n<li>Milk<\/li>\n<li>Pet food<\/li>\n<li>Soap<\/li>\n<li>Saliva<\/li>\n<li>Cleaning liquids<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">Typical examples include:<\/p>\n<ul data-spread=\"false\">\n<li><a href=\"https:\/\/www.lyasilicone.com\/de\/produkt\/custom-silicone-bath-toys-for-baby-kids-oem-soft-waterproof-animal-bath-toy-manufacturer\/\"><strong>silicone baby bath toys<\/strong><\/a><\/li>\n<li>Baby feeding bowls and plates<\/li>\n<li>Silicone bibs<\/li>\n<li>Straw cups<\/li>\n<li>Bottle accessories<\/li>\n<li>Pet lick mats<\/li>\n<li>Pet feeding bowls<\/li>\n<li>Grooming brushes<\/li>\n<li>Collapsible travel products<\/li>\n<li>Silicone cleaning accessories<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The cleaning challenge is different for every product.<\/p>\n<p class=\"isSelectedEnd\">A feeding bowl mainly needs accessible food-contact surfaces.<\/p>\n<p class=\"isSelectedEnd\">A bath toy needs to avoid hidden water-retention areas.<\/p>\n<p class=\"isSelectedEnd\">A pet lick mat may require textured feeding patterns without creating grooves that are too narrow to rinse.<\/p>\n<p class=\"isSelectedEnd\">A brush may need drainage between bristles so that water does not remain trapped around the base.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"Why_Can_Silicone_Products_Retain_Water\"><\/span>Why Can Silicone Products Retain Water?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3>1. Closed Cavities Can Trap Water<\/h3>\n<p class=\"isSelectedEnd\">Hollow products may contain internal spaces for:<\/p>\n<ul data-spread=\"false\">\n<li>Squeezing<\/li>\n<li>Weight reduction<\/li>\n<li>Product shape<\/li>\n<li>Water-play function<\/li>\n<li>Assembly<\/li>\n<li>Decorative design<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">If water enters a cavity but cannot leave easily, the product may remain wet internally.<\/p>\n<p class=\"isSelectedEnd\">A single very small hole does not always provide effective drainage.<\/p>\n<p class=\"isSelectedEnd\">The design should consider:<\/p>\n<ul data-spread=\"false\">\n<li>Where water enters<\/li>\n<li>Where air enters<\/li>\n<li>Where water exits<\/li>\n<li>How the product is positioned during drying<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">In some applications, an openable structure may provide better cleaning access than relying only on a small drainage hole.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h3>2. Drainage Holes May Be in the Wrong Position<\/h3>\n<p class=\"isSelectedEnd\">The lowest point of the product in actual use may not be the lowest point when the product is standing, hanging or drying.<\/p>\n<p class=\"isSelectedEnd\">For example, a drainage hole located correctly in a CAD drawing may still leave water inside when the customer places the product upside down.<\/p>\n<p class=\"isSelectedEnd\">The engineering team should review several orientations:<\/p>\n<ul data-spread=\"false\">\n<li>Normal use<\/li>\n<li>Washing<\/li>\n<li>Rinsing<\/li>\n<li>Hanging<\/li>\n<li>Air drying<\/li>\n<li>Verpackung<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">Drainage should be evaluated based on how customers will actually handle the finished product.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h3>3. The Drainage Hole May Be Too Small<\/h3>\n<p class=\"isSelectedEnd\">A very small opening may restrict water flow.<\/p>\n<p class=\"isSelectedEnd\">It may also become more difficult to clean if residue reaches the opening.<\/p>\n<p class=\"isSelectedEnd\">However, simply making every hole larger is not the solution.<\/p>\n<p class=\"isSelectedEnd\">Hole size can affect:<\/p>\n<ul data-spread=\"false\">\n<li>Product appearance<\/li>\n<li>Structural strength<\/li>\n<li>Finger accessibility<\/li>\n<li>Squeezing performance<\/li>\n<li>Water-play function<\/li>\n<li>Mold structure<\/li>\n<li>Demolding<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The correct opening should balance drainage with the product&#8217;s intended function.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"Why_Do_Deep_Grooves_Make_Silicone_Products_Harder_to_Clean\"><\/span>Why Do Deep Grooves Make Silicone Products Harder to Clean?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Texture is often used to create:<\/p>\n<ul data-spread=\"false\">\n<li>Slow-feeding patterns<\/li>\n<li>Sensory surfaces<\/li>\n<li>Grip<\/li>\n<li>Decoration<\/li>\n<li>Brand identity<\/li>\n<li>Massage effects<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">But texture also changes cleaning accessibility.<\/p>\n<p class=\"isSelectedEnd\">A deep narrow groove may collect:<\/p>\n<ul data-spread=\"false\">\n<li>Food residue<\/li>\n<li>Pet food<\/li>\n<li>Soap<\/li>\n<li>Fibers<\/li>\n<li>Hair<\/li>\n<li>Water<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The problem is not simply whether the silicone material itself is washable.<\/p>\n<p class=\"isSelectedEnd\">The question is whether water, fingers, brushes or cleaning tools can physically reach the entire surface.<\/p>\n<p class=\"isSelectedEnd\">When designing textures, buyers should review:<\/p>\n<ul data-spread=\"false\">\n<li>Groove width<\/li>\n<li>Groove depth<\/li>\n<li>Corner radius<\/li>\n<li>Texture spacing<\/li>\n<li>Drainage direction<\/li>\n<li>Brush accessibility<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">A visually complex pattern may look attractive in a rendering but become inconvenient during everyday cleaning.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"Why_Are_Rounded_Transitions_Better_for_Easy_Cleaning\"><\/span>Why Are Rounded Transitions Better for Easy Cleaning?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Sharp internal corners create narrow areas that are more difficult to wipe or rinse.<\/p>\n<p class=\"isSelectedEnd\">Rounded transitions can provide:<\/p>\n<ul data-spread=\"false\">\n<li>Better cleaning access<\/li>\n<li>Smoother water flow<\/li>\n<li>Fewer narrow residue areas<\/li>\n<li>More practical demolding<\/li>\n<li>Lower stress concentration<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">Rounded geometry is particularly useful around:<\/p>\n<ul data-spread=\"false\">\n<li>Bowl bottoms<\/li>\n<li>Feeding channels<\/li>\n<li>Internal toy cavities<\/li>\n<li>Handle connections<\/li>\n<li>Brush bases<\/li>\n<li>Drinking openings<\/li>\n<li>Lid interfaces<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The required radius depends on the product size and structure.<\/p>\n<p class=\"isSelectedEnd\">The goal is not to make every design completely round, but to avoid unnecessary sharp internal geometry in areas that require frequent cleaning.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"Should_a_Bath_Toy_Be_Fully_Sealed_or_Openable\"><\/span>Should a Bath Toy Be Fully Sealed or Openable?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Both approaches can work, but they solve different design problems.<\/p>\n<h3>Fully Sealed Structure<\/h3>\n<p class=\"isSelectedEnd\">A sealed silicone bath toy prevents water from entering the internal cavity.<\/p>\n<p class=\"isSelectedEnd\">Advantages may include:<\/p>\n<ul data-spread=\"false\">\n<li>No internal water storage<\/li>\n<li>Simple exterior cleaning<\/li>\n<li>Fewer removable parts<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">However, the sealing structure must remain reliable during molding and use.<\/p>\n<h3>Openable Structure<\/h3>\n<p class=\"isSelectedEnd\">An openable bath toy allows the customer to separate the product for rinsing and drying.<\/p>\n<p class=\"isSelectedEnd\">Advantages may include:<\/p>\n<ul data-spread=\"false\">\n<li>Direct access to internal surfaces<\/li>\n<li>Easier visual inspection<\/li>\n<li>Faster manual drying<\/li>\n<li>Easier removal of water<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">However, the connection must be designed carefully.<\/p>\n<p class=\"isSelectedEnd\">Buyers should evaluate:<\/p>\n<ul data-spread=\"false\">\n<li>Assembly force<\/li>\n<li>Child access<\/li>\n<li>Component fit<\/li>\n<li>Wall thickness<\/li>\n<li>Repeated opening<\/li>\n<li>Cleaning<\/li>\n<li>Product-market requirements<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The choice should be made during <a href=\"https:\/\/www.lyasilicone.com\/de\/custom-silicone-mold-development-checklist\/\"><strong>custom silicone mold development<\/strong><\/a>, because changing between sealed and openable

Be Designed?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Food-contact textures should balance feeding function with cleaning access.<\/p>\n<p class=\"isSelectedEnd\">For a silicone pet lick mat, buyers should consider:<\/p>\n<ul data-spread=\"false\">\n<li>Texture height<\/li>\n<li>Groove width<\/li>\n<li>Pattern density<\/li>\n<li>Corner radius<\/li>\n<li>Overall mat flexibility<\/li>\n<li>Suction-cup layout<\/li>\n<li>Dishwasher or hand-cleaning method<\/li>\n<li>Drying orientation<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">Very dense patterns may hold food effectively but require more cleaning.<\/p>\n<p class=\"isSelectedEnd\">A practical design should allow the customer to reach the important surfaces with normal washing methods.<\/p>\n<p class=\"isSelectedEnd\">For feeding bowls and plates, internal corners should also be evaluated.<\/p>\n<p class=\"isSelectedEnd\">A visually sharp bowl transition may create a narrow area where food repeatedly remains.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"How_Do_Suction_Cups_Affect_Cleaning\"><\/span>How Do Suction Cups Affect Cleaning?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Suction cups add useful function but also create additional geometry on the underside of a product.<\/p>\n<p class=\"isSelectedEnd\">Multiple deep suction cups may create:<\/p>\n<ul data-spread=\"false\">\n<li>Additional water-retention areas<\/li>\n<li>More surfaces that require rinsing<\/li>\n<li>Narrow gaps between cups<\/li>\n<li>Slower drying if products are stacked immediately<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">The design should consider both suction function and cleaning.<\/p>\n<p class=\"isSelectedEnd\">For example, the distance between suction cups should allow water to escape instead of creating isolated pockets.<\/p>\n<p class=\"isSelectedEnd\">The product should also be evaluated in the position customers are likely to use for drying.<\/p>\n<div contenteditable=\"false\">\n<hr \/>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"Why_Should_Cleaning_Be_Reviewed_During_DFM\"><\/span>Why Should Cleaning Be Reviewed During DFM?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">A <a href=\"https:\/\/www.lyasilicone.com\/de\/custom-silicone-mold-development-checklist\/\"><strong>DFM review<\/strong><\/a> should include more than checking whether a silicone product can be molded.<\/p>\n<p class=\"isSelectedEnd\">For products exposed to food or water, the engineering review should also ask:<\/p>\n<ul data-spread=\"false\">\n<li>Can every important surface be reached?<\/li>\n<li>Can water leave the product naturally?<\/li>\n<li>Are there hidden cavities?<\/li>\n<li>Are grooves unnecessarily deep?<\/li>\n<li>Can the product dry in a practical position?<\/li>\n<li>Does the product need to be disassembled?<\/li>\n<li>Can the customer reassemble it correctly?<\/li>\n<li>Will packaging keep the product wet or compressed?<\/li>\n<li>Does the structure create difficult mold features?<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">These questions are easier to address before mold machining.<\/p>\n<p class=\"isSelectedEnd\">After the mold is

Water from Becoming Trapped?<\/h3>\n<p class=\"isSelectedEnd\">No.<\/p>\n<p class=\"isSelectedEnd\">Silicone can be water-resistant, but product geometry determines whether water remains inside a cavity or groove.<\/p>\n<h3>Is One Drainage Hole Enough for a Hollow Product?<\/h3>\n<p class=\"isSelectedEnd\">Not always.<\/p>\n<p class=\"isSelectedEnd\">The result depends on cavity shape, hole position, air flow and drying orientation.<\/p>\n<p class=\"isSelectedEnd\">The final molded sample should be tested with actual water.<\/p>\n<h3>Are Deep Textures Bad for Silicone Products?<\/h3>\n<p class=\"isSelectedEnd\">Not automatically.<\/p>\n<p class=\"isSelectedEnd\">Deep texture can provide useful feeding, sensory or grip functions, but cleaning access should be considered during design.<\/p>\n<h3>Is an Openable Bath Toy Better Than a Sealed Bath Toy?<\/h3>\n<p class=\"isSelectedEnd\">Neither is universally better.<\/p>\n<p class=\"isSelectedEnd\">A sealed structure keeps water out, while an openable structure provides direct internal cleaning access.<\/p>\n<p class=\"isSelectedEnd\">The correct design depends on product function and applicable requirements.<\/p>\n<h3>Can Drainage Holes Be Added After the Mold Is Finished?<\/h3>\n<p class=\"isSelectedEnd\">Some tooling modifications may be possible, but changing drainage geometry can affect the cavity, wall thickness and product function.<\/p>\n<p class=\"isSelectedEnd\">It is better to review drainage before tooling.<\/p>\n<h3>Should Cleaning Be Tested Before Mass Production?<\/h3>\n<p class=\"isSelectedEnd\">Yes.<\/p>\n<p class=\"isSelectedEnd\">The final molded product should be tested using realistic washing, rinsing, draining, drying and repeated-use conditions.<\/p>\n<div

class=\"ez-toc-section-end\"><\/span><\/h2>\n<p class=\"isSelectedEnd\">Easy cleaning is not created only by choosing silicone material.<\/p>\n<p class=\"isSelectedEnd\">The finished product also needs suitable:<\/p>\n<ul data-spread=\"false\">\n<li>Drainage<\/li>\n<li>Access<\/li>\n<li>Groove geometry<\/li>\n<li>Rounded transitions<\/li>\n<li>Drying orientation<\/li>\n<li>Removable structures<\/li>\n<li>Mold design<\/li>\n<\/ul>\n<p class=\"isSelectedEnd\">Before opening a mold for a water-contact or food-contact silicone product, buyers should review how the product will be washed, drained and dried in real use.<\/p>\n<p>To review an easy-clean custom silicone product design, send <a href=\"https:\/\/www.lyasilicone.com\/de\/contact\/\"><strong>LYA-Silikon<\/strong><\/a>
