| Plywood and Block Board manufacturing process: |
¡°We catch every signal of our customer needs.¡± |
At SGU, plywood and other products are manufactured at company¡¯s sophisticated plant with minutest attention to the details, which is characteristic of each and every SGU product. The manufacturing process strictly conforms to IS and international quality standards. |
For manufacturing of high quality plywood and other products, SGU goes through meticulous procedures of acquiring quality raw materials. |
The manufacture process of plywood, block boards, flush doors can be divided into following stages: |
- Acquisition of raw material
- Preservation
- Treatment Gluing
- Pressing Finishing
- Quality Inspection is an ongoing process
|
The procurement of raw materials for glue, resins, face veneers, core veneers, planks goes through rigid quality assurance procedures that ensure only high-end quality raw materials are used in the manufacturing process at SGU. |
SGU encourages eco-friendly means of production and to implement it in its own unit, it uses plantation timbers that saves tropical forest wood and generates revenue to agri business. SGU plywood and other products are manufactured from high quality veneers of uniform thickness. These veneers are peeled off carefully from the quality wood by fully automatic pneumatically controlled peeling machines. Storage of these raw materials is batch marked to assure quality. |
The core veneers are dried in dryer conveyor and inspection is conducted to check moisture. Core veneers are then loaded in chopper to chop for end squareness. For block boards and flush doors, planks are dried in seasoning chamber, moisture is inspected, boards are cut to frame baton and planed at the planer to form core frame that are then filled with smaller sized batons to form core board. The core board is hot-pressed in dryer conveyor and moisture-inspected. |
| |
|
For plywood, the core veneers are then coated with waterproof glue and bonded with face veneers. Incase of block boards and flush doors, the glued core veneers are bonded with face veneers and core board as well. In-process inspection is conducted. |

| Veneers are then stacked and subjected to controlled temperature and high pressure in the hot press until the glue is cured. After pressing, the plywood or board panels are stacked for cooling and batch marking. The final SSS come out with higher density in comparison with the other products available in the market. |

| |
| |
|
At every stage of manufacturing process, stress relieving treatment like tenderization are given to make it warp free and dimensionally stable. |
|
|
The plywood or board panels are trimmed and cut to required length and width. Sanding of plywood or board is followed by hand finishing. Preservative treatment on each and every piece are done and dried to make it withstand all types of wood destroying organisms, viz., termites, white ants, fungus and other micro-organisms. Plywood are stacked, finished, gaps putty filled and process of plywood or board coloring begins. This is followed by marking/stenciling on plywood and board |

| Laboratory |
Finished plywood and board panels are carefully inspected and graded. Final inspection is conducted conscientiously. Quality control inspectors check finished plywood and board panels in the inventory. Samples selected at random are tested in SGU¡¯s laboratory. Random samples are subjected to the boiling test to obtain absolute boiling water resistant bond. It |

| |
can be boiled continuously for many hours without any degradation and delaminating. Samples are mycologically tested to determine anti micro-organisms. Some samples are subjected to humidity test as well. Samples are shear tested to determine the strength of the glue bond. SGU products can be successfully used under the severest of tropical climatic conditions. |
|
|
| |
The test results are compiled and reports are circulated. The SGU "Mark of Excellence" is an assurance to consumers that our products meet the high quality standards established by the industry and that it will perform in a satisfactory and predictable manner. |
|
|
| |
| The quality is better than the best, the price is economical and products demonstrate high quality caliber without any exception whatsoever. Our assurance for quality shall definitely make you comfortable and peaceful for the rest of your life. |
