A logo adjustment may sometimes require only local tool modification, while changes to wall thickness, product size, holes, suction geometry or mating surfaces may affect multiple mold features or require major rework.

class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-start=\"3805\" data-end=\"3898\">Some changes can be relatively localized when the mold was designed with replaceable inserts.<\/p>\n<p data-start=\"3900\" data-end=\"3921\">Examples may include:<\/p>\n<ul data-start=\"3923\" data-end=\"4053\">\n<li data-section-id=\"1ro9wrh\" data-start=\"3923\" data-end=\"3945\">Certain molded logos<\/li>\n<li data-section-id=\"1rgdl7r\" data-start=\"3946\" data-end=\"3964\">Small local text<\/li>\n<li data-section-id=\"hmdhzb\" data-start=\"3965\" data-end=\"3988\">Limited texture

data-end=\"4173\">For example, changing a logo may affect:<\/p>\n<ul data-start=\"4175\" data-end=\"4266\">\n<li data-section-id=\"1d7g91q\" data-start=\"4175\" data-end=\"4187\">Logo depth<\/li>\n<li

class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-start=\"11747\" data-end=\"11836\">After a meaningful mold modification, the next step should be a controlled sample review.<\/p>\n<p data-start=\"11838\" data-end=\"11930\">Do not move directly into mass production simply because the modified mold closes correctly.<\/p>\n<h3 data-section-id=\"1306e5e\" data-start=\"11932\"

silicone mold always be modified?<\/h3>\n<p data-start=\"16430\" data-end=\"16433\">\u041d\u0435\u0442.<\/p>\n<p data-start=\"16435\" data-end=\"16585\">Many molds can be modified, but feasibility depends on the original tool construction, geometry, modification direction and available machining space.<\/p>\n<h3 data-section-id=\"hbun0v\" data-start=\"16587\" data-end=\"16623\">Is changing a logo usually easy?<\/h3>\n<p data-start=\"16625\" data-end=\"16764\">It can be relatively localized, especially when the tool uses a replaceable logo insert, but this should be confirmed from the actual mold.<\/p>\n<h3 data-section-id=\"tu8zlf\" data-start=\"16766\" data-end=\"16816\">Can I increase the product size after tooling?<\/h3>\n<p data-start=\"16818\" data-end=\"16956\">Sometimes, but increasing finished-product dimensions may require significant cavity modification. The exact solution depends on the mold.<\/p>\n<h3 data-section-id=\"19lqr96\" data-start=\"16958\" data-end=\"17010\">What happens if I change silicone hardness only?<\/h3>\n<p data-start=\"17012\" data-end=\"17197\">A hardness change may not require physical mold modification, but it can affect flexibility, demolding, suction, fit and user feel. The new material condition should still be validated.<\/p>\n<h3 data-section-id=\"1gke3q6\" data-start=\"17199\" data-end=\"17252\">Do I need a new Golden Sample after every change?<\/h3>\n<p data-start=\"17254\" data-end=\"17469\">A meaningful approved product revision should have a reference that represents that version. For very small administrative changes that do not affect the physical product, a new physical sample may not be necessary.<\/p>\n<h3 data-section-id=\"1e9fy1u\" data-start=\"17471\" data-end=\"17519\">Can I change the mold after mass production?<\/h3>\n<p data-start=\"17521\" data-end=\"17688\">Yes, when technically feasible, but existing inventory, old-version components, packaging and production records need to be controlled so that revisions are not mixed.<\/p>\n<h3 data-section-id=\"3a469i\" data-start=\"17690\" data-end=\"17749\">Should the new revision be tested in every mold cavity?<\/h3>\n<p data-start=\"17751\" data-end=\"17874\">When the modification can influence cavity-produced features, every active cavity should be evaluated during qualification.<\/p>\n<h3 data-section-id=\"v9xcyu\" data-start=\"17876\" data-end=\"17938\">Does a mold modification always cost less than a new mold?<\/h3>\n<p data-start=\"17940\" data-end=\"17943\">\u041d\u0435\u0442.<\/p>\n<p data-start=\"17945\" data-end=\"18054\">If the modification is extensive or creates high repair risk, a new insert or new mold may be more practical.<\/p>\n<hr data-start=\"18056\" data-end=\"18059\" \/>\n<h2 data-section-id=\"1l3za87\" data-start=\"18061\" data-end=\"18111\"><span class=\"ez-toc-section\"
