Our article on how cap thread is measured covers diameter, pitch and DIN18 in more detail.<\/p>\n<h2>Tips for filling and capping<\/h2>\n<h3>Set the closing force by testing<\/h3>\n<p>Too little closing force and the cap may loosen. Too much and the TE bridges can break during capping, which defeats the point of the ring. We do not give a single torque value here, because the right setting depends on your bottle, your product and your equipment. Start low, increase gradually, and inspect the ring after each step.<\/p>\n<h3>Check the ring after capping<\/h3>\n<p>On a production run, pull a sample every so often and look at the TE ring. If bridges are broken or the ring is shifted before the bottle leaves the line, adjust your capping setup.<\/p>\n<h3>Keep the bottle neck clean<\/h3>\n<p>Oil residue on the thread makes caps harder to seat and can lead to uneven closing force. Fill carefully and wipe the neck if needed.<\/p>\n<h3>Hand capping for small batches<\/h3>\n<p>For small runs, hand capping is fine if the operator works consistently. For larger volumes, a semi-automatic or automatic capper gives a more repeatable result.<\/p>\n<h2>Storage and handling of caps<\/h2>\n<ul>\n<li>Keep caps in their original cartons or bags until needed, away from dust.<\/li>\n<li>Store them away from heat sources and direct sunlight. This is a sensible habit for any plastic part.<\/li>\n<li>Keep wooden caps dry and away from high humidity.<\/li>\n<li>Do not mix colors or ring styles in the same open container on the line, as they look similar at a glance.<\/li>\n<\/ul>\n<h2>Uobi\u010dajene pogre\u0161ke<\/h2>\n<ul>\n<li><strong>Ordering by color only.<\/strong> Black caps come in two ring styles. Confirm which one you need.<\/li>\n<li><strong>Skipping the fit test.<\/strong> Always check a sample on your own bottles.<\/li>\n<li><strong>Over-tightening on the line.<\/strong> This can damage the TE ring before the product ships.<\/li>\n<li><strong>Assuming every cap is tamper-evident.<\/strong> The wooden cap is a different type, so check the product data.<\/li>\n<li><strong>Ignoring the filled-product test.<\/strong> Check the product in the sealed bottle, not just an empty one.<\/li>\n<\/ul>\n<h2>\u010cesta pitanja<\/h2>\n<h3>Are these caps only for DIN18 (GL18) bottles?<\/h3>\n<p>Yes. All caps in the Caps &#8220;FortiLock&#8221; range listed here are made for DIN18 (GL18) necks. Do not use them on other neck finishes.<\/p>\n<h3>What is the difference between a recessed and a prominent TE ring?<\/h3>\n<p>A recessed ring sits closer to the cap profile and looks cleaner. A prominent ring stands out more, so the break after first opening is easier to see.<\/p>\n<h3>Is the wooden cap tamper-evident?<\/h3>\n<p>The product data for the wooden cap with PP DIN18 thread does not list a tamper-evident ring.
