If you&rsquo;re an engineer specifying a plastic component, a buyer sourcing from China, or a product manager evaluating manufacturing options, this guide covers everything you need to know.</p> <h2 id="how-injection-molding-works">How Injection Molding Works</h2> <p>Injection molding is a cyclic manufacturing process with four distinct phases:</p> <h3 id="1-clamping">1. Clamping</h3> <p>The injection mold — a precision-machined steel tool with a cavity in the shape of your part — is held closed under high pressure by the clamping unit of the injection molding machine. Clamping force is measured in tonnes and must exceed the injection pressure multiplied by the projected area of the part.</p>
