Injection molding has greatly advanced since 1834, when a British pewterer, Joseph Morgan, applied for the first patent for injection moulding candles. Injection molding is simply a manufacturing process whereby molten material is injected into a mold and allowed to cool, producing parts. Subsequently, British, American, and German inventors patented several modifications in the injection molding field in the nineteen and twentieth centuries.
Since then, injection molding has made slow but steady progress. From making simple products such as hair combs to now producing complex products found in the automotive, medical, aerospace, and consumer goods industries, injection mold companies are now central to everyone’s lives.
