Real metal cold casting is a method in which metallic powders are combined with a suitable soft plastic, or resin, to create a wide variety of different mold castings that look like real metal and weigh about the same as well. Once the resin is heated to a thick consistency, it can either be brushed, also called slush-cast, onto the surface of the mold. After this is left to set, pure resin or, depending on the particular look and application that is required, a resin mixed with metal powder is applied over this gel coat. The advantages of the metal cold cast process over actual molten metal castings are that it is a much faster process and costs significantly less.
Metallic powders used in cold castings produce beautiful colors on the surface of the casting, especially when combined with intricate patterns. Alumidust Metallic Powders are specially made for this method and work great. They are also versatile and very easy to use, whether mixed directly with the casting resin, or slush-cast onto the mold.
Alumidust only needs to be applied sparingly, so a small container of a particular color will last quite a long time. Further, it is a non toxic substance so it makes the whole cold casting process much safer than alternative methods. To make a casting stand out and look bright, the powder should be brushed into a high gloss silicone rubber mold - the glossier the better.
From darker shades to lighter hues, as well as a selection of metallic colors, metallic powders are available in a range of colors to suit many different applications. This makes them very cost effective and easy to handle.
One popular project what these powders are used for is creating fishing lures of soft plastic, by dusting them directly onto the mold. This is a great alternative to making hard lures; soft lures are much faster to make and don't need air brushes or compressors, nor excessive ventilation.
The making of soft plastic lures can be quite dangerous because of the flammable paints that are needed; however, using Alumidust powders makes the whole process so much safer and easier. The procedure is simple; the mold itself is first painted, or dusted, instead of the lure. It is important to note that the outside color is the one that needs to be applied first.
The plastic is then heated, and when ready simply poured into the mold. It is allowed to cool until it sets. Next, the clear coat plastic is heated up until quite thin. The lure is dipped into this mixture for a few moments by holding it from the tail end until almost fully submerged. The final steps involve lifting it out to allow the excess liquid coat to drip off, then leaving it to cool and set.
