Clay is heated when kneaded and dehydrated out of its core. This heating vacuum kneading apparatus controls the latter process easier.
The kneaded clay is made into roofing tiles in this production line. Each piece is shaped accurately.
Molded roofing tiles are dried carefully so that their shape and measurement stays consistent. Manufacturers of the roofing tiles in the Sekisyu area, adopting the method of drying them over the grid, to meet the needs of consumers.
The roofing tiles produced in Sekisyu area are characterized by being glazed and fired in the kiln. Our original glazes have enjoyed an established reputation for their waterproof effectiveness.
The firing temperature can be raised above 1,200℃ (2,192°F) by use of LPG. As a result, the hardened glazed surface embodies beauty and sturdiness.
Finally, the roofing tiles produced automatically are double-checked both with the naked eye and with an automated warp inspecting apparatus. Onlyproducts passed by inspection are shipped.
Bound and wrapped automatically, finished products are shipped to various areas, domestic or foreign.
