Plastic industry What Is Injection Molding Used For? Your Official Guide
Content in this Article What is Injection Molding? Injection molding is process tailored for producing large volumes of parts. Compared to other manufacturing technologies—like CNC machining and 3D printing—it requires an upfront, capital investment into tooling. The steps involved in the injection molding process are as follows: Step 1: Design the mold. Step 2: Create the mold. Step 3: Inject the molten plastic (or other material) Step 4: Cool the plastic (or other material) Step 5: Remove the part.
Today, screw injection machines represent the vast majority of injection machines. Other widely used molding methods include blow molding, compression molding, or vacuum molding (thermoforming). Now, the injection molding market has reached $300 billion. This process produces more than 5 million tons of plastic parts yearly worldwide. Here's a quick reference guide to wall thicknesses, surface finishes, materials, and other important features for rapid injection molding.
