The invention discloses a process for producing integrated ultraviolet cured crystal keys, which is characterized by comprising the following steps of: 1, manufacturing a die; 2, pouring an ultraviolet curable adhesive into the die and covering polycarbonate (PC)/thermoplastic urethane (TPU)/polyethylene terephthalate (PET) film for molding and curing; 3, printing character lines on the PC/TPU/PET film, baking, assembling silicon rubber on the PC/TPU/PET film to form a crystal key board, and baking the assembled crystal key board in a baking oven; and 4, cutting the baked crystal key board on a carbon dioxide laser cutting machine, and forming keys on the key board. By the process, the traditional key assembling process is simplified, the cost is reduced, and the production efficiency is improved; meanwhile, the pressing handfeel of the product is improved, the appearance of the product is beautified, and the product better meets the market requirement for thick crystal keys at present.
