    • The present invention relates to the recycling of exhausted wax in a process of lost wax micro casting, comprising the steps of: - molding of one or more wax models, identical to the end pieces to produce, using a first formulation of wax; - molding of one or more molds of sprues (connecting passages), using a second formulation of wax; - assembling of said one or more models and said one or more molds of sprues, to form a cluster; - coating of said cluster with a ceramic shell; - removing of wax from said shell; - treating of said shell in an oven; - casting of molten metal alloy within said shell and subsequent cooling to obtain a solidified casting; - cracking of the shell to release the solidified casting; - removing of the sprues and finishing of the pieces; and characterised in that it additionally comprises the following steps: - melting of the exhausted wax coming from said step of removing wax from said shell, to obtain a molten exhausted wax; - removing of water from said molten exhausted wax, to obtain de- hydrated molten exhausted wax; - removing of ceramic residues, ashes or other impurity by filtration of said de-hydrated molten exhausted wax, to obtain recycled wax; - adding virgin wax (grade 50-60°C) in a quantity equal to at least 30% by weight of the total of the recycled wax, and at least equal to the amount of recycled wax in the case in which the same has been already obtained following a process of lost wax micro casting in which a wax formulation that contain recycled wax was used, to obtain said second formulation of wax; - delivering of said second formulation of wax to said molding of one or more molds of sprues.

    • Embodiments of the invention are directed to an automated crayon-molding device comprising a crayon-receiving member, an automated heating element, a crayon-melting chamber that is heated to a melting temperature by the automated heating element, and at least one mold. The crayon-receiving member receives the crayon at one end and has a closure mechanism at another held, preventing the crayon from entering in the crayon-melting chamber until it reaches a melting temperature. Once the inside of the crayon-melting chamber, the crayon melts and drips into a mold configured to receive melted wax. Embodiments of the invention also include a method for assembling an automated crayon- molding device and a system for molding crayons that includes a crayon-receiving member, an automated heating element, a crayon-melting chamber, a drawer positioned underneath the crayon-melting chamber, and at least one mold.
    • 本发明的实施例涉及一种自动蜡笔模制装置,其包括蜡笔容纳构件,自动化加热元件,蜡笔熔化室,蜡烛熔化室通过自动化加热元件被加热到熔化温度 ,以及至少一个模具。 蜡笔容纳构件在一端接收蜡笔并且在另一个容纳蜡烛接收构件处具有关闭机构,防止蜡笔进入蜡笔熔化室直到其达到熔化温度。 一旦蜡笔熔化室的内部,蜡笔熔化并滴入模具中以接收熔化的蜡。 本发明的实施例还包括用于组装自动蜡笔模制装置的方法和用于模制蜡笔的系统,其包括蜡笔接收构件,自动化加热元件,蜡笔熔化室,位于蜡笔熔化室下方的抽屉 ,并至少有一个模具。
