Furniture Manufacturing Process:
The quality control process when manufacturing furniture starts at a very early stage. The Timber is carefully selected by experts with over 30years experience in the furniture industry. Logs are chosen for their maturity and girth. And the timber sawn from these logs are of the highest quality with prominence given to strength and grain. These logs are purchased at a premium. Also, all timber purchased are from licensed timber dealers or directly from the State Timber Corporation.
Whilst Craft Supplies specializes in Mahogany timber, we also work with Teak, Sooriya Mara, Nadum and a variety of local timbers depending on the requirements of the customer and the volume of the order.
All products which have areas covered by fabric usually have a treated hardwood carcass. The timber mostly used for carcasses is Gini Sapu. For example, in a sofa suite, the carcass is made out of a treated hardwood and all external visible timber areas would be of luxury timber (Mahogany, Teak etc).
Seasoning, Treating and Kiln Drying
Once the timber is purchased and sawn to the required sizes they are placed in the timber seasoning Kiln. To prevent warping and cracking of the planks it is necessary to reduce the moisture content of each plank. This is done by placing the planks in a kiln which reduces the moisture content to the required level of between 12% and 15%. This process also eliminates most of the insects which breed inside the wood. The entire kiln drying process takes approximately two weeks where the timber is monitored 24hours a day during this time.
Once the timber is kiln dried it is treated with wood preservative chemicals which destroys any insects which were not eliminated during the kiln drying process.
The carpentry process comprises of high-tech machinery and a highly skilled carpentry group. Traditional carpentry methods renowned the world over are used for joinery and overall finish. These methods add to the strength and longevity of the finished product. Also, by using special concealed joinery methods it gives the final product an unmatched look of quality.
Special attention is given when planks are joined for table tops and wardrobes. Each plank has a cross section where the growth rings are visible at each end. We ensure that each plank is joined alternately where the growth rings face opposite directions. Warping usually takes place along the direction of the growth rings, this process ensures that the final product is extremely strong and prevents warping. This also means that when more planks are used for a product the stronger the product is, however it is essential to make the final product look like it has been made by a single plank. The special concealed joinery methods mentioned above enable us to manufacture a product with these qualities.
The lacquers used for the finishing of our products are the highest quality available in Sri Lanka. All table tops are finished with an imported Polyurethane (PU) lacquer which is stain resistant to liquids ranging from boiling hot water to liquor and nail varnish remover. A total of 3 coats are used for all products where after each coat, the product is sanded down and the process repeated. This gives the product a protective barrier against spills and stains and also makes the final product have a rich look of quality.
Maintenance of these products is very easy due to this finishing process. Most products can be cleaned by using a slightly damp cloth.
Our manufacturing process enables us to use raw materials from a host of suppliers depending on the requirements of our customers. Imported upholstery fabrics to local handloom fabric cab be sourced based on the requirements of our customers. Our fittings and fixtures which include slow closing hinges and self closing drawer railings are available from world renowned manufacturers.
