I was once curious about how so many identical Lego pieces were made, which led me to discover injection moulding. The beauty of injection moulding lies in its ability to produce massive quantities of exactly identical plastic items at a cost-effective rate. The process involves melting plastic pellets and injecting the molten plastic into a carefully crafted mould. Once it cools and solidifies, the mould opens to release a perfectly shaped piece. This method is invaluable for large-scale production because it takes mere minutes to produce complex parts with minimal waste. The precision allowed by the mould ensures each piece meets strict specifications, perfect for maintaining high quality in high-volume orders. Beyond Lego, this technique applies to numerous products we encounter daily, from automotive parts to medical devices. As I was looking into it, I found a useful page, https://www.tatra-rotalac.com/injection-moulding... - that could be worth your time. Come to think of it, understanding this process sheds light on modern manufacturing marvels we often take for granted.
