    Study Notes

    Injection Molding Process

    • In the injection cylinder, the plastic pellets are melted to form a molten material.
    • The component responsible for mixing the molten pellets in the injection cylinder is the screw.

    Loading Process

    • The plastic pellets are loaded into the hopper before the injection process begins.

    Specifications

    • The overall policy statement is a part of the specification that outlines the general guidelines and objectives.
    • Poor specifications can lead to errors, defects, and increased costs.
    • It is essential to divide the specification into three parts to ensure clarity, organization, and ease of understanding.
