Core Pin: The Hidden Hero in Precision Moulding
In the world of manufacturing and injection moulding, even the smallest components can make the biggest difference. One such critical part is the Core Pin —a tool that shapes the inner cavities of moulded products with remarkable accuracy. While often overlooked, core pins are essential for achieving fine details, smooth finishes, and precision in every moulded part. What Exactly is a Core Pin? A Core Pin is a slender, high-strength tool steel or carbide insert used in moulds to create holes, slots, or intricate cavities inside moulded parts. From automotive components to medical devices, core pins enable manufacturers to design parts with complex internal geometries that would otherwise be impossible or expensive to machine afterward. Some of their key applications include: Creating through-holes or blind holes. Forming narrow cavities or slots. Reducing the need for post-processing operations. The Challenge: Core Pin Breakage Despite their strength, core pins are vulnerable t...
