Reverse tilt pour casting is ideal for large castings with heavy sections and consistent geometry or center symmetry, like a wheel or a thick square lid. In the example below, the thick riser will be the last to solidify, pulling all the gas and shrink into this section that will be cut off. Therefore, you target a heavy section that will be removed from the casting. Like a static pour, you are feeding material into the center of the part. Reverse tilt pour castings reap the benefits of a machine-controlled tilt pour, bringing more consistency and less turbulence. It’s almost identical to the tilt pour process, but the casting is center fed like a static pour (metal going into a riser, directly into the part). The reverse tilt pour is a mixture of both static pour and tilt pour. These industries require reliable, strong, sanitary parts with a high-end look. For example, permanent mold tilt pour castings are common in the medical equipment industry and food equipment industry. Tilt pour castings are ideal for products requiring high density and low-porosity. It models and casts like clay, and sets up hard like plaster in about 30 minutes. You can add hydraulics, loose pieces, slides, and cores into a tilt pour permanent mold where you can’t in a static pour mold. Sculptamold is lightweight like papier mach, but it does not shrink. Tilt pour castings create opportunity for more complexity. With static pour, part complexity is constrained by the mold cavities, how the mold opens, and cores. Finally, it returns to its vertical position, and ejects the casting.īy machine controlling the tilt timing and flow, you have better control of turbulence and porosity. The machine sits completely horizontal to allow the metal to solidify in the mold. Then, the machine slowly tilts to allow the metal to smoothly flow into the mold. First, the operator pours metal into a pour cup. Unlike static pour, tilt pour is machine controlled. Air pockets or high porosity can make your part weaker, less dense, and difficult to machine and powder coat. It decreases turbulence, which decreases porosity. The tilt pour method is like pouring a beer down the side of a glass. It is ideal to machine this center heavy section out.įor denser, more aesthetic parts, we recommend tilt pour or reverse tilt pour. Since static pour dumps directly into the center of the part, this section will have the most potential for gas and shrink. However, static pour is sometimes used in permanent mold for small round parts where the center will be bored out, like wheels. The diagram above shows a static pour into a sand mold. The static pour is most commonly used in sand casting. Therefore, castings may have inconsistent porosity due to varying turbulence and pour speed. This pouring method is not machine controlled, which means the flow of the metal will depend on the operator. Cake Mold for home baking Tilt the adjustment handle, shrink it at will. The static standard or dump pour is just as it sounds: the metal is poured directly into the mold. Buy Cake Mold Adjustable Stainless Steel Cake Mousse Mould Baking Square Form. There are 3 common ways to pour molten metal into a permanent mold: static pour, tilt pour, and reverse tilt pour.
