Template and production method of template

The invention discloses a formwork and a production method of the formwork. The formwork comprises a formwork body, a side wall, a hook assembly and a heat preservation layer. The plate body is provided with a plate face facing the first direction, the side wall is arranged on the edge of the plate face, and an installation space is defined by the side wall and the plate face. The hook assembly is connected with the plate body and located in the installation space. The heat preservation layer is arranged in the installation space and detachably connected with the hook assembly. According to the formwork, the hook assembly is detachably connected with the heat preservation layer, so that the heat preservation layer is detachably fixed to the formwork body, the heat preservation performance of the formwork body is changed, the purpose that the formwork is used in different periods is achieved, the idle period of the formwork is shortened, and the purpose of improving the use efficiency of the formwork is achiev
