BAMBOO PRESS MANUFACTURE PROCESS IN VIET NAM
- Materials: fresh neohouzeaua and bamboo (from forest)
- Time of production: time depends much on the material resource and weather and it will take at least 30 days from starting splitting bamboo to splint
Neohouzeaua and bamboo are steeped in water (in pond and lake) from 3 to 4 months to make the material durable and for anti-termite and wood-eater.
Picking up the material and dry them for 10 to 20 days: Drying and shrinking them.
Splitting bamboo into slim and flat splints (4-5 days)
Selecting the best ones, then smooth and dry them (4-5 days)
Using the dried splints to form the product by 2 ways:
+ Rounding it on the mould
+ Joining it on flat
(Using alcohol to stick or fix it with nail or pin)
Producing raw product from rounding or joining flat pieces (4-5 days)
Coating the product with a glue layer on the dried ones: fixing product.
Drying product by drying (3-4 days). Smoothing them by sandpaper, cutting and whittling them to have semi-product called "Voc".
