    SPI

    SPI finishes are a set of standard mould finishes with different polished textures for enhanced properties.

    Notes:

    A1, A2, A3, B1, B2, B3, C1, C2, C3, D1, D2, D3

    Final result:

    • Heavily polished, to semi-gloss to fine and coarse matte depending on the selection

    VDI

    VDI is an international standard for mould texturing of matte surfaces. It is mainly processed by Electrical Discharge Machining (EDM) when mould machining.

    Notes:

    VDI12, VDI15, VDI18,VDI21, VDI 24, VDI27, VDI30, VDI33, VDI36, VDI39, VDI42, VDI45

    Final result:

    • Fine-to-coarse grain depending on the selection

  • Custom Finishing

    If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually takes 1-2 business days.

    Notes:

    Submitting for manual review with a custom request does not guarantee a quote.
