Then, the bamboo can be placed in a high-temperature and high-pressure furnace for high-temperature steam softening treatment. The furnace pressure is maintained between 1.5 MPa and 3.6 MPa, the temperature is maintained between 120 ° C and 140 ° C, and the time is maintained between 1 hour and 4 hours. The main mechanism is to use high temperature and high pressure to degrade the chemical components in the bamboo, reduce the amount of alcohol and ether bonds, and make hemicellulose, Lignin degrades, producing more aldehyde, ketone or hydroxy bonds.
4、 自然或风机干燥竹材， 保持含水率在 12%至 22%之间。  4. Naturally or fan-dried bamboo, keeping the moisture content between 12% and 22%.
5、将竹材进行碾压至开裂。该过程可根据竹材的厚度和宽度而定， 如果是厚度和宽度小或极小， 可省略该步骤。  5. Roll the bamboo to crack. This process can be determined according to the thickness and width of the bamboo. If the thickness and width are small or extremely small, this step can be omitted.
6、 将竹材置入模具中进行冷压， 压力一般大于 20Mpa， 此时， 使 竹材在高压下， 相互间的距离缩小， 达到键键重新组合， 形成新键型 的目的。 如果竹材厚度和宽度小或极小， 可不规则排列放入模具中， 反之则呈规则排列。  6. Put the bamboo into the mold for cold pressing. The pressure is generally greater than 20Mpa. At this time, the distance between the bamboos under high pressure is reduced, and the key is recombined to form a new key. If the thickness and width of the bamboo are small or small, they can be placed in the mold irregularly, and vice versa.
