Description:

It is a strong, lightweight material that is resistant to breaking and shattering. PET material can be clear or opaque, and can be dyed or printed with designs. It is also recyclable. This material has a melting point of about 244°C; hence, molding is done at a high temperature. It is a hard material with low moisture absorption. It has good resistance to chemicals as well as good strength and stiffness. It is used for the production of capacitors, recording tapes, bottles, and electrical components.

    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.
