We always advise clients to ask for the &#8220;ECO hourly rate&#8221; and &#8220;standard lead time for die modification&#8221; before signing the contract.

However, the weight of the finished part is rarely the weight of the material you are paying for. This is known as the &#8220;Buy-to-Fly&#8221; ratio. In stamping, you pay for the skeleton (the strip of metal left over) and the offal (the slugs punched out).<br \/><a href=\"https:\/\/en.wikipedia.org\/wiki\/Buy-to-fly_ratio\">Relaci\u00f3n Comprar-Volar<\/a> <sup><sup id=\"ref-4\"><a href=\"#footnote-4\">4<\/a><\/sup><\/sup><\/p>\n<p>If a supplier uses an inefficient nesting layout\u2014placing parts too far apart on the strip or failing to interlock complex shapes\u2014your material utilization could drop from 80% to 50%.

A stamped bracket might need deburring to remove sharp edges, zinc plating for corrosion resistance, or heat treatment for hardness.<\/p>\n<p>If your RFQ (Request for Quotation) specifies &#8220;Zinc Plated,&#8221; but the quote says &#8220;Price per part (Stamping only),&#8221; you are walking into a trap. The supplier can later claim that the plating requirement was &#8220;not standard&#8221; or requires a specific vendor, adding 20% to 40% to the final cost.<\/p>\n<h3>Log\u00edstica de acabados externalizados<\/h3>\n<p>Muy pocas empresas de estampado tienen l\u00edneas internas de recubrimiento o tratamiento t\u00e9rmico debido a las regulaciones ambientales. Esto significa que sus piezas deben ser:<\/p>\n<ol>\n<li>Estampadas.<\/li>\n<li>Empaquetado en contenedores temporales.<\/li>\n<li>Transportado en cami\u00f3n a una instalaci\u00f3n de galvanoplastia.<\/li>\n<li>Desempaquetado, galvanizado y reempaquetado.<\/li>\n<li>Transportado de regreso al estampador para la inspecci\u00f3n final.<\/li>\n<\/ol>\n<p>Los costos ocultos aqu\u00ed son <strong>transporte<\/strong> y el <strong>da\u00f1os por manipulaci\u00f3n<\/strong>. Who pays for the truck to the plater? Who pays for the parts bent or scratched during this double-handling? If the quote lists &#8220;Plating: $0.05,&#8221; does that include the freight and the 5% scrap rate typical of the plating process? Often, it does not.<\/p>\n<h3>Desbarbado: El asesino silencioso del presupuesto<\/h3>\n<p>El desbarbado es quiz\u00e1s el costo m\u00e1s pasado por alto. El estampado deja naturalmente una rebaba en el borde cortado.<\/p>\n<ul>\n<li><strong>Vibrado:<\/strong> Un proceso a granel que es relativamente barato pero puede abollar piezas delicadas.<\/li>\n<li><strong>Desbarbado electroqu\u00edmico:<\/strong> Preciso pero caro.<\/li>\n<li><strong>Desbarbado manual:<\/strong> Extremadamente laborioso e inconsistente.<\/li>\n<\/ul>\n<p>If the print says &#8220;Free of Burrs,&#8221; and the supplier assumes a quick tumble while you expect a perfectly smooth machined-style edge, the re-quote for manual deburring can destroy the project&#8217;s economics. We always recommend defining the &#8220;Acceptable Burr Height&#8221; (e.g., Max 0.05mm) to force the supplier to quote the correct removal method.<\/p>\n<h3>Operaciones dentro de la matriz vs. Pasos secundarios<\/h3>\n<p>Los estampadores avanzados pueden realizar roscado (agujeros roscados) o inserci\u00f3n de herrajes (tuercas PEM) dentro de la matriz. Esto aumenta el costo de las herramientas, pero reduce dr\u00e1sticamente el precio por pieza.<\/p>\n<ul>\n<li><strong>Escenario A (Secundario):<\/strong> Estampar pieza ($0.50) -&gt; Mover a m\u00e1quina de roscado -&gt; Operador rosca agujeros ($0.20).
