12 PROCESS FOR PROVIDING METAL CASTINGS USING THE LOST FOAM METHOD US15175356 2016-06-07 US20170297086A1 2017-10-19 Mark DeBruin
3-D printed PLA material of a selected density is formed into a pattern that is configured as the outer shell of a casting form to be used in the lost foam or evaporative casting process. The purpose of 3-D printing of the PLA material is used to maintain the proper configuration of the form to facilitate casting, and reduce buildup of carbon on the surface of the casting. Because the form is essentially hollow, PLA support pieces can be used on the interior to maintain the structural integrity of the form.

15 Sandcasting pattern coating compositions US10072638 2002-02-07 US06960367B2 2005-11-01 Victor Steven LaFay; Stephen Louis Neltner
Sand casting is an old art. In this molding process sand is compacted around a pattern and the pattern is removed, leaving a mold cavity the shape of the pattern. Molten metal can then be poured into the cavity to form the object. To increase the life of the mold, and to make removal of the pattern easier, the pattern must be coated with a protective material. Despite many available pattern coating compounds, mineral seal oil, and a mixture of mineral seal and clay, have been the commercial choices. Hereby the advantages of mineral seal oil-clay pattern coating compositions are retained without its detriments by utilizing a vegetable oil base in a pattern coating composition to replace some or all of the mineral seal oil to provide biodegradable coating compositions with reduced VOC content.

An object is to propose a mold release agent improving the state of a mold surface by repeating casting cycle so as to extend the life of the metal mold actively, and a casting method using the mold release agent. A water-soluble mold release agent applied on a mold surface of a metal mold contains organic acid or organic acid salt which is reducing and ligand, wherein concentration of a total thereof is not less than 0.01 wt % in using concentration and is not more than a fixed concentration which is stability limit of emulsion of the mold release agent in undiluted concentration. Construction weight ratio of the organic acid or organic acid salt which is reducing and the ligand is in the range from 99/1 to 30/70. The mold release agent is applied on a mold surface of a die casting metal mold, molten metal is injected into the metal mold, and the organic acid or organic acid salt which is reducing in the mold release agent is reacted with a component of the mold surface so as to deoxidize Fe2O3 on the mold surface to Fe3O4.
