Mold Design: How are injection molds designed and engineered?

First, a basic understanding: molds, or tools, consist of two halves, generally called “Half A” and “Half B”. Once a part is designed, an engineer uses specialized software to render the final design into a 3D model. This model is then loaded into a multi-axis CNC machine which cuts the two halves of the tool from a solid block of metal. If you’re interested in learning more about the physical tools, including the types of material used to build the molds, feel free to check out our page dedicated to the topic. 

Nelson-Miller’s engineers have received advanced education in the design and engineering of plastic injection molds, providing them with the training to design molds for maximum efficiency (less material cost) while adhering to the injection molding industry’s “Best Practices”.
