How to Start Gypsum Board Manufacturing Business

    Gypsum board is the generic name of a panel-type product consisting of a noncombustible core. The products are used in False Ceilings, Light partition walls, etc for better appearance & thermal insulation properties. Such Boards use gypsum with paddy husk, Jute sticks & Fibre, coir, etc.

    Gypsum Boards are preferred in indoor uses as wood & plywood have become costlier and timber destruction can be reduced by using them. It is an environment-friendly product. Gypsum board walls and ceilings have a number of outstanding advantages like fire-resistive, sound attenuating, durable, economical, versatile, etc. Additionally, you can initiate gypsum board production on a small and medium scale basis.

    Different Types Of Gypsum Board & Applications

    The product is developed through modern technology to meet specific requirements of the industry. It is mainly used as the surface layer of interior walls and ceilings; as a base for ceramic, plastic, and metal tile; for exterior soffits; for the elevator and other shaft enclosures; as area separation walls between building units; and to provide fire protection for structural elements.

    Most gypsum board is available with an aluminum foil backing that provides an effective vapor retarder for exterior walls when the foil surface is applied to the framing. according to the thickness, there are different types of gypsum boards are available. Such as

    • 1/4-in. A low-cost gypsum board is used as a base in a multi-layer application for improving sound control, or to cover existing walls and ceilings in remodeling.
    • 5/16-in. A gypsum board is used in manufactured housing.
    • 3/8-in. A gypsum board is principally applied in a double-layer system over wood framing and as a face layer in repair or remodeling.
    • 1/2-in. Generally used as a single-layer wall and ceiling material in residential work and in double-layer systems for greater sound and fire ratings.
    • 5/8-in. Used in the quality single layer and double-layer wall systems. The greater thickness provides additional fire resistance, higher rigidity, and better impact resistance.
    • 3/4-in. Used in a similar manner to 5/8-in.
    • 1-in. Used in interior partitions, shaft walls, stairwells, chase ways, area separation walls and corridor ceilings. Manufactured only in 24 in. wide panels and usually installed as an integral part of a system.

    Depending on the type and the use, you can produce a gypsum board with a tapered, square, beveled, rounded, or tongue and groove edge. Some gypsum board types may incorporate a combination of different edge types.

    Gypsum Board Market Opportunities

    We have seen a pickup in the gypsum board business in recent quarters. The major reason is the improvement of the construction markets as well as a more aggressive pricing strategy among manufacturers.

    Gypsum-based panels are the most common building blocks used for interior walls and ceilings. It is still a low-cost substitute for plywood, hardboard, and wooden panel Boards, all of which cause depletion of forest resources. Gypsum Boards are also a preferred interior decoration item for commercial establishments.

    With high priority attached to the housing and increased flow of finance towards low-cost houses, demand for Gypsum Plaster Boards has increased. There is a good market potential of gypsum board as a profitable investment opportunity for the entrepreneurs.

    Gypsum Board Production Registration & License

    In starting the business, you will need to apply for different registrations and licenses from Govt. authorities. We have listed here the basics. This is recommended to check your state’s law before initiating the venture.

    Gypsum Board Production Machinery & Raw Materials

    An approximately covered area of 186 sqm. is sufficient to set up the machinery and manufacturing operation. Major required utilities are electricity and water. The required machinery are as follows

    • Alteration type Disc Pulveriser with 7 H.P. Motor
    • 2.5 M long 2M Dia Cylindrical Rotary Drum Calciner with coal-fired roasting oven
    • Platform type weighing the balance of 100 kg capacity
    • Wooden Tables with polished Marble Top
    • Moulds Hand Tools, slurry making Tank, etc.
    • Testing equipment

    Gypsum and plaster of Paris are the principal raw materials of the unit. Apart from this, you will need to procure packaging consumables.

    Gypsum Board Manufacturing Process

    The manufacturing process includes several steps.

    Step-1

    Gypsum is Disc Pulverized after drying. Then calcine the item in Rotary Drum Calciner at 140°C to 170°C for about two hours.

    Step-2

    After cooling, pulverize the plaster of Paris again to a mesh of 150°C. Then, mix the fine plaster with coloring material. After that, make them into a slurry by adding water.

    Step-3

    Pour the slurry into molds where you place the reinforcement materials. The upper surface is smoothened by wooden reaper or straight wooden planks and excess material is recycled by mixing in the slurry.

    Step-4

    Properly set boards are removed from molds and placed on wooden racks for drying in the shade for 3 to 4 days. After drying, gypsum boards are packed in Corrugated Cardboard sheets and Boxes for sales.
