|How to Use Different Mold Making Methods|
1. Pour Block mold method: This is the go-to method. Because ComposiMold is clear. You can always make it into a cut block mold. The technique is a simple: place your master into a mold box and pour ComposiMold over it. It gives you a sense of what the mold will look like, and you can always re-melt it and make it a different way. If your part is lightweight and will float in water, hot glue it to the bottom of the container.

2. Cut block mold: Almost as easy as the pour block method. Make a pour block method and then cut out your master where you want the parting line to be. Because ComposiMold is a clear rubber that you can cut with scissors or a knife, we just pour it over the part, allow the ComposiMold to cool, and cut the mold in half. Sounds easy, and for the most part it is. You will still have to worry about where to make the parting line and keeping the part together while casting the new piece. There is no reason why more complex molds with three or pieces cannot be made using this same techniques.
3. The Press Mold: With ImPRESSive Putty, just press your Putty over the part you are molding. The nice part about the rubber molding putty is that you don’t need a mold box. However, you will lose a little detail on the corners.
The Brush-on Mold or Paint on Mold: Paint-on molds are made by painting the molding material directly onto a model’s surface. The advantages of a paint-on mold are that it is possible to use less material and you can mold parts that you could not do with a typical molding process. An example where you may need to use a Paint-on mold is making a mold of something attached to a wall.
5. 2 Part Mold Making Method: In many cases, it is best to prepare the mold in two parts. This may be because there are specific undercuts that you need to mold around, you want to make a parting line that is not straight, or you want a three part mold. The two part mold is well suited for dramatic undercuts that would leave spaces or voids in your mold. Use clay or polymer clay to build up around the figurine. Build up the area to the point where you want the parting line in the mold. This parting line is selected to allow the mold to be separated easily. After the clay is completed, lightly cover the master part and clay with a mold release. Pour ComposiMold over the Master and clay to make the first half of your mold. When the ComposiMold has solidified, pull off the first half of the mold, flip your Master and pour ComposiMold over the part again being sure to have mold release in between the layers, and in larger molds chill your first ComposiMold half before pouring the second. After the second ComposiMold half has solidified, pull it off of the Master. Pull out the Master part from the mold. You are now ready to make your casting.
