The design process for pump moulds is meticulous, requiring a deep understanding of materials, manufacturing techniques, and the end-use of the product. The designer must consider the flow of the material during the injection process, ensuring that the mould design allows for even distribution and minimal waste. This involves creating channels, known as gates and runners, that facilitate the material's path into the mould cavity. https://www.ld-capmould.com/product/bottle-cap-mould/5-gallon-cap-mould.html
