mold components

Standard mold parts are used extensively in almost all modern injection mold tools. Only a few special-purpose tools are constructed from Scratch, without taking advantage of the standard components available. Even these tools would have a small number of standard parts in them such as guide pillars, ejector pins and liner bushes.
The advantages of using standard mold parts are considerable. Some of the major advantages are listed below:

  • Components are usually available ex stock,
    Quality is guaranteed
    Parts are made to close tolerances, so accurate interchangeability is assured.
    A wide variety of sizes and materials is available
    Standard parts cost less to buy than they would to make in a tool room.
    Using standard parts enables toolmakers to concentrate on making the cavity inserts and other custom parts,
    Using standard parts cuts down delivery times for tool manufacture.
    Tool rooms can produce more mold tools than they could otherwise.
    Replacement parts are easy to obtain and fit, making maintenance easier.
    CAD-compatible software from standard parts suppliers is available for reducing design times.
