Abstract: The present invention is related to the production method of the two-layer composite deck tile (1) which comprises the process steps of melting, first of all, the wood-plastic filling material which is used as the top layer (10) and filling the same into the prepared injection mold cavity; then melting the thermoplastic bottom layer (11) which allows the composite deck tile (1) to be high-positioned on the ground where it will be applied and filling the same into the injection mold cavity; allowing the two layers (10, 11) to cool down which are filled into the mold cavity; and removing thereof from the mold after cooling down, so as to be used in the outdoor areas or for floor coverings.
