Abstract
A system for crafting railroad crossties of compressed bamboo is described. The system employs a hydraulic press configured to effectively compress multiple stalks of bamboo into a strong unified beam within a mold. Bamboo is first mashed, dried, and treated. A resin is employed as a permanent adhesive, binding the stalks together. The bamboo is stacked within a mold and compressed under the pressure exerted by the hydraulic press. An oven is used to heat the compressed bamboo, and then the bamboo is cooled. The compressed bamboo beam may then be trimmed to remove excess bamboo, and is cut into crosstie segments if needed. The resulting crosstie is sturdy, ecologically friendly, and rapidly manufactured.
