In narrow rib cavities, high shear rates occur during injection, causing accelerated erosion of the mold steel. Hardened tool steel (e.g., H13) or coatings are recommended.<\/p>\n<p><strong>Q3: What is the minimum thickness for a rib to fill properly?<\/strong><br \/>\n<strong>A:<\/strong> Generally, the tip of the rib should not be less than 0.75mm to 1.0mm. If it is thinner, the injection pressure required to fill it may spike, or the material may freeze off before filling (short shot).<\/p>\n<p><strong>Q4: How does \"coring out\" relate to rib design?<\/strong><br \/>\n<strong>A:<\/strong> Coring out involves removing thick sections of material to maintain uniform wall thickness. Ribs are then added back into the cored-out area to restore the strength lost by removing the bulk material.<\/p>\n<p><strong>Q5: Can gas-assist injection molding help with thick ribs?<\/strong><br \/>\n<strong>A:<\/strong> Yes. Gas-Assist Injection Molding (GAIM) allows for hollow ribs. Nitrogen gas is injected into the melt stream, coring out the rib from the inside. This allows for much thicker ribs without sink marks, as the gas pressure packs the plastic against the mold walls.<\/p>\n<p><figure><img decoding=\"async\" src=\"https:\/\/zetarmold.com\/wp-content\/uploads\/2025\/11\/plastic-mold-design-diagram.webp\" alt=\"Desenho de nervuras de pl\u00e1stico\"><figcaption>Desenho de nervuras de pl\u00e1stico<\/figcaption><\/figure>\n<\/p>\n<h2>Resumo<\/h2>\n<p>Rib design is a balance between structural engineering and rheology.
