Injection molding stands as a pivotal manufacturing technology, enabling the efficient production of large quantities of identical items. At its core, this process involves injecting molten materials into a carefully crafted mold, referred to as "mould" in the United States. The versatility of injection molding extends across various materials, encompassing metals, glassware, elastomers, and even confections. However, it finds its most prevalent application in working with thermoplastic and thermosetting polymers.
The injection molding process begins with the selection of a suitable material, typically a polymer in granular form. This material is then fed into the injection molding machine's hopper, where it undergoes a melting process. Once molten, the material is injected into the mold under high pressure, taking the shape of the mold cavity. This mold, often precision-engineered to meet exact specifications, determines the final form of the product. The injected material cools and solidifies within the mold, facilitating the creation of thousands of identical items with remarkable consistency and precision.
