Start a Block Board And Flush Door Shutters (Wooden Solid Core)

(208) Start a Block Board And Flush Door Shutters (Wooden Solid Core)   

Block Board: Block Boards are a kind of plywood in which the veneers are glued on both sides on wooden battens frame. Wooden strips are placed across a surface of one or more boards to prevent, warping and strengthening etc. Block Boards are used for making furniture, cabinets, partitions, interior/ exterior decorative wood working etc.

Flush Door: Flush Doors are also a kind of block board which is used to make door panels and differ in sizes according to the size of door.
Market Potential
As a raw material, wood has several unique characteristics and properties. Properly seasoned wood is light in weight compared to most materials of constructions and fabrication. Wood is a poor transmitter of sound, heat and electricity. Wood is easier to work, to paint and to preserve in the presence of sea water than most competitive materials. There are many other remarkable properties and characteristics of wood which provide for a variety of its usage and products. Block boards and flush doors are among these products.
Block boards and flush doors are seasoned boards and have all the properties of wood like, ease to work, to paint etc. These have advantages over raw wooden planks for the reason that these boards are more strong and free from war page. Now a days in almost all the sectors of society, the use of plywood, board is becoming common for it is cheaper than wood and stronger as well. These boards doors are available in standard sizes. They can also be used in partitions, making furnitures, interior and exterior decorations etc. The surfaces of the boards are always smooth so laminating board with mica or otherwise is easy. Looking at these advantageous properties of boards, these are now becoming popular and used in almost all the houses, offices, bungalows, commercial complexes etc. In view of the urban/rural development and growth of construction activities and increasing replacement of old traditional wooden fittings with the boards, it can be easily presumed that these boards have a tremendous market potential.
Basis and Presumptions
This project scheme has been prepared on the basis of prevailing rates, which may vary from time to time and place to place. The entrepreneurs putting up this unit must check up/verify the following points at the time of conception:
1. Unit should run in single shift of 8 hours, 300 working days in a year.

2. It is envisaged that the unit can utilise 75% of its total installed capacity.

3. Labour wages, cost of plant and machinery, interest on capital investment etc. have been taken as prevailing at the time of preparation of this report.

4. Margin money requirement, terms of loan etc. may vary from institution to institution.
5. Interest on capital investment has been taken @ 12% per annum.
Implementation Schedule
It is estimated to take about 6 months, from conception to implementation and commercial production, which includes preparation of project report, liaison with financial institutions, purchase of plant and machinery, erection and
commissioning, recruitment of staff and labour, clearance from all the concerned departments etc.
Technical Aspects
Process of Manufacture
Plywood, block boards and flush doors are made from a similar process, the difference between block board/ flush doors and plywood is only that the solid core of block boards and flush doors is made up of wooden battens frame, whereas the plywood is made from veneer gluing on one another. Plywood consists of three or more sheets of veneer glued together, with the grains of alternate sheet usually laid cross wise. The resulting material has distinct advantages for many uses as it is strong and free from war page etc. There are many gluing materials available in the market but Urea Formaldehyde is normally used and Phenyl Formaldehyde is used in plywood or block boards for exterior uses as this type of gluing material provides water or weather resistance properly to the boards.

1. Water is mixed in proportionate quantity in powder resin with small quantities of GHCP, TSP, LA and Maida to make liquid glue in glue mixer.
2. Liquid glue is spread on core veneer with the help of rollers on glue spreader.

3. Different layers of core and face veneers are set manually on wooden battens frame and stacked in the press and compressed with the help of steam in Hydraulic hot press.

4. After the boards are properly pressed and dried, these are taken out and side cutting is done on DD saw. Saw wastage of side cutting is used as fuel in boiler.

5. Top layer finishing is done on sanding machine by sanding belt.
Flow Process 

Glue mixer - Glue spreader - Face and core veneer stacking - Hydraulic hot press - DD saw - sanding - finished boards.
In case of manufacture of flush doors, the production process remains same except the solid core is made from, a frame of battens in required sizes and face veneers are glued with phenyl formaldehyde which gives the door water resistance property.
Quality Control and Standards
Block boards are required to be manufactured as per IS 1659:1990 (Third revision, Amendment No. 3). Flush doors are to be manufactured conforming to IS 2202:1991 (Part I : Fifth revision).

Bureau of Indian Standards has suggested some tests for block boards and flush doors in IS 4020:1998 (Parts 1 to 16) which should also be followed.
