    Precision-Cut Polymer Components

    We offer a comprehensive range of shapes, from simple OD’s/ID’s as well as complex components, made to your exact requirements and specified tolerances.
    The precision-cut polymer components that we manufacture, are uniquely colour-coded to identify their specific thickness, giving customers a quick visual reference to use the right shim or spacer for each application, without the requirement to use a micrometre.

    Please see our colour-coded Polymex® chart below for a full breakdown.
