Meiken Lamwood Corporation, a laminated lumber manufacturer in Okayama prefecture, has completed the construction of a CLT production plant, the first in Japan, according to the ITTO.
The plant has a total floor space of 6,000m2. Another processing plant takes up about 3,400m2. The first floor of the plant features a lamina drying stacking machine with four kiln dryers. Steam is generated from a biomass power plant across the road while waste from the molder is used as fuel.
Dried laminas between the lengths of 2,000 and 4,200mm are sent to the second floor, where it goes through stress tests, moisture measurement, a surface scanner, horizontal finger jointer and finally, a six axis moulder. Finished lamina of 8-12 metres are trimmed and sent to press after an adhesive sprayer.
The maximum size of the CLT produced is 12,000 mm in thickness. Adhesive is isocyanate. While there are no orders yet, the plant intends to produce 30,000 cubic metres a year in three years time.
