Biography | njection molding generally uses molds made in two parts. The first part is the cavity, which gives a concave part its external shape. The second part is the core, which gives a part its internal shape. The cost of the mold depends on the geometry of the part being made; as the part become complex, the mold increase in complexity and hence more expensive. During the injection molding process, an injection molding machine melts and inject thermoplastic into the mold under high pressure. The molten plastic then takes on the shape of the mold, cools and solidifies. The formed part is then ejected from the mold. An ejection system is needed to push the part off the mold because the part shrinks onto the core as it cools. This is accomplished with ejection pins and they are usually located in the core of the mold. |
