Since its introduction in the 1850s, injection molding has made the production of low-cost and high-cost plastic parts seamless and easy. Today, different types of plastics—each with varying melting points—are used for injection molding, making it a versatile solution for a wide range of industries striving to produce a great volume of high-quality and cost-efficient parts. Traditionally, molds used in plastic injection molding comprised two plates: one containing the cavity and one containing the core. However, today, computer-assisted manufacturing (CAM) is utilized to create modern molds, which can be significantly more intricate than their two-plate predecessors, containing multiple parts and sections. Today’s molds are detailed and designed to exact specifications allowing a higher complexity in the molded product.
Furthermore, improved injection molding software and technology, which will only continue to advance, allow manufacturers to save time, reduce waste, and increase throughput. They provide the ability to analyze designs and plastic flow through molds, which means parts can get into production quicker as the time required for the testing and refinement phases is drastically cut. In fact, the newest software programs include the ability to simulate how melted plastic flows during the injection molding process, enabling makers to better predict manufacturing-related defects. Furthermore, the software allows designers to evaluate and modify part manufacturability and make the necessary adjustments early in the design process. Beyond this, modern innovations also minimize the rate of faulty production and enhance the significance of injection molding technology in the mass production of complicated plastic shapes.
In any manufacturing, sustainability remains vital, and efforts to improve persist. In injection molding, specifically, in addition to bio-resins and eco-friendly additives, efforts continue to reduce waste and enhance recycling. Going forward, manufacturers will continue to place a larger focus on using as many recyclable materials as possible throughout the injection molding industry to improve their environmental footprints.
