Changing one element can change bond behavior.<\/p>\n<h2>Use geometry to support the interface<\/h2>\n<p>Through-holes, grooves, undercuts and wraparound features can add mechanical retention where the design allows. They should not create trapped air, weak rigid sections or impossible demolding.<\/p>\n<h2>Protect the shutoff<\/h2>\n<p>The mold must close against the insert without damaging it or allowing uncontrolled silicone flash onto critical surfaces. Insert tolerances and fixture repeatability therefore affect the silicone result.<\/p>\n<h2>Control contamination and surface condition<\/h2>\n<p>Oil, release agent, moisture, oxidation or inconsistent texture can interfere with bonding. The required cleaning, primer or self-bonding material route should be agreed for the actual substrate.<\/p>\n<h2>Test the load that matters<\/h2>\n<p>Pull, peel, torque, leak and thermal-cycle tests answer different questions.
