Medium density fiberboard (mdf)

  1. 1. MEDIUM DENSITY FIBERBOARD (MDF) Presented by: CHE MOHAMAD AZRUL BIN CHE LAH (2012102157) ZULKHANAIN BIN MAT ZAIN (2012146285) MUHAMMAD ARBAIN BIN MAT YUTI (2012930753) MUHAMAD AZLAN BIN ABDULLAH (2012349855) IZZAH AZIMAH BINTI NOH (2012717865)
  2. 2. INTRODUCTION TO MEDIUM DENSITY FIBERBOARD (MDF)
  3. 3. DEFINITION  Medium-density fiberboard (MDF) is a composite wood product made of compressed wood fibres, mixed with wax and resin.  MDF is similar to particleboard and hardboard,it is known for its strength, smooth surface and edges and affordable pricing.  MDF has many applications and various sizes and comes with its share of advantages and disadvantages, and is overall a very popular choice for many woodworkers.
  4. 4. CONT…  Usually the panel will compressed to density of 0.5 to 0.8 specific gravity in a hot press.  It varies in color from tan to chocolate brown.  Common thicknesses range from 1/4 in. to 1 in., but most home centers carry only 1/2-in. and 3/4-in. Full sheets are oversized by 1 in., so a “4 x 8” sheet is actually 49 x 97 in. A full sheet of 3/4-in.

  6. 6. TYPES OF MDF EXTERIOR GRADE INTERIOR GRADE
  7. 7. INTERIOR GRADE MDF  There are various types of MDF available. The most common, and cheapest is standard interior grade material.  This is suitable for most internal applications where moisture is not a consideration.
  8. 8. EXTERIOR GRADE MDF  Other grades of MDF include Moisture Resistant for use in areas of moderate moisture.  Exterior grade MDF can be used externally for cladding or signage work.  For applications where weight is a prime consideration other, lower densities of fibreboard are available.
  9. 9. APPLICATION OF MDF  Cabinet doors and drawer fronts  Internal cabinet carcasses  Display cabinets  Exhibition plinths  Lettering & Logos  Exterior signage  Exterior cladding  Boxes and casework  All types of furniture
  10. 10. ADVANTAGES  Less expensive than wood, easier to work with, more uniform and more stable of a material.  Won't warp, check or crack and has no knots or surface grain which makes it easier to cut, drill into, file or paint.  Can be painted to produce a smooth quality surface. Oil, water- based paints and varnishes may be used on MDF
  11. 11. CONT…  MDF may be dowelled together and traditional woodwork joints may even be cut.  MDF may be glued together with PVA wood glue.. Veneers and laminates may also be used to finish MDF  Big-dimensioned sheet, customer-required size.
  12. 12. CONT…  Stable quality from overall-controlled production, some properties better than natural wood, such as water-proof, fire-extinguishing, antipressing, less variability, etc.  Product surface satisfies direct use's requirement, saved much processing cost.  Solid interior property, constant quality in the longitudinal and transverse direction.
  13. 13. DISADVANTAGES  Medium-density fiberboard is a heavier material than most solid woods, and because it's so hard and dense, MDF may dull saw blades and router bits more quickly than solid wood.  MDF also causes potential problems if the edges become waterlogged since the material will swell.
  14. 14. CONT…  There is a health danger from using MDF because most MDF panels are made with resins that contain formaldehyde, a suspected carcinogen. It is best to wear a respirator and safety goggles and provide adequate ventilation when you cut or sand MDF to avoid inhaling the dust.  The cutting edges of your tools will probably dull quickly due to the glue fibres in the MDF.
