How to Design an Injection Mold - 3D Insider

Mar 24, 2019 · The process of injection molding involves pushing a melted plastic mixture under a certain pressure through a cavity of a tightly held mold. The mold is also under a certain clamping pressure depending upon the viscosity of the plastic fluid being injected. The molten plastic flows inside the mold and takes the shape of the mold. Then, the plastic is allowed to cool down and set. Finally, the mold is opened up and the solidified plastic part is pushed out using ejector pins. The mold …
