Pre Laminated MDF Boards

  • Product Description:

    Medium Density Fibre Board is an engineered wood product formed by first breaking softwood into wood fibres, combining the same with wax and resin and then forming panels by applying high temperature and pressure. It is a building material similar in application to plywood which is made of separated fibres, but not wood veneers and is denser than particle board.

    Application Area:

    Wall Panels
    Cabinets
    Cupboards
    Modular office furniture
    Table-tops
    Modular home furniture

  • Cutting:

    The boards can be cut to required sizes using hand/machine saws. In case of hand saw use only fine tooth saw and always keep it at a low angle for cutting to ensure clean sharp edges
    In case of machine saw, carbide tipped saw is recommended. Poly-crystalline diamond tipped saw should be used for cutting large volumes

    Machining and Carving:

    The main advantage of MDF is its excellent and easy surface routing and edge shaping capability. It results in clean, sharp reproduction of designs which are free from fuzz and fibre pull (Provided the tools are well maintained and used correctly.)
    MDF can also be worked with standard hand tools. It must be ensured that blades and cutters are sharp at all times

    Fixing and Joining:
    Fixing and joining techniques in MDF are similar to methods used in most other wood products. In MDF, for screwing, following methods should be adopted:

    Use only a fully threaded parallel shank
    Drill pilot holes before screwing to avoid splitting
    Do not over-tighten screws as further tightening will reduce the holding power
    Never hammer the screws
    Distance of screw from corner, on surface and edges should be minimum 25 mm and 75 mm respectively

    Nailing:

    Nailing can be done for typical applications like upholstery, with nails no thicker than 17 gauge. In case of pneumatic guns for volume production, adjust air pressure to avoid excess penetration of the staple. To achieve best holding power, keep the staple just below the surface
    Distance of screw from corner, on surface and edges should be minimum 25 mm and 75 mm respectively, space of individual nails/staples should be minimum 150 mm c/c

    Adhesives:
    It can be glued using most of the branded adhesives available in the market.

    Hardware:

    Only fully threaded parallel shank steel screws of proper size should be used
    Dowels made of plastic, metal or bamboo can be used. Diameter of the hole should be slightly larger than the dowel to allow good adhesive coverage and to avoid splitting
    All types of hinges can be used
    Cam and dowel fittings are used for CKD units where right angle joints are required
    All types of locks can be used

  • Storage:

    Storage area must be dry and well ventilated
    MDF should always be stored in horizontal stacks on a flat surface
    Sheets should be lifted clear off the floor using dry bearers
    Minimum sheet bearers should be provided every 50 boards of same thickness
    Spacing between bearers not to exceed 800 mm c/c
    Bearers supporting successive layers should be in vertical alignment
    Use plastic sheets if extreme damp conditions are expected
    Protect corners and edges during loading/unloading
    Do not slide, drag or drop the boards
    Prior to use, it is recommended that conditioning of the site must be done for minimum of 48-72 hours

    Maintenance:

    No edge of the Pre-lam MDF should be naked. Exposed parts should be covered with edge banding tape
    Water retention is not allowed
    Rest care as per General Purpose Laminates
