Sinking is a process used to create cavities in steel blocks for molding plastic or forging. It can also be used to add information to various materials through die-cutting and indentation. The process involves cutting sheet metal, creating an outline, and hammering steel letters into the metal to create an indentation. The final product can be enhanced with colored polymer.
Sinking is a process used to machine or create a specific size or shape cavity or opening in steel blocks. The openings in the steel blocks can then be used to mold the plastic into different shapes. These openings can also be used during forging, both hot and cold, or for coining or die casting.
Most often, sinking is used to place names, numbers and other sources of information on the metal. It can also be used to place such elements on a piece of wood, leather or many other materials. The process for sinking is quite simple and something anyone can do with a few simple tools. There are also larger machines that can help with the process, but these machines come at a price.
The die casting process begins with obtaining a piece of sheet metal and cutting it into a shape. For example, the shape could be a shield or a name tag. When doing the sinking process, it is important to use a piece of sheet metal for the project that is at least 1/64 inch (0.4 mm) thick.
Once the shape has been placed on the piece of sheet metal, you will need to cut it out. To do this, a chisel and a hammer or in any case special equipment for cutting sheet metal is used. Once the piece has been trimmed, you need to file down any rough edges.
After the shape has been fully cut out, the die-cutting process begins to add letters and numbers. A scheme must be created containing the information to be placed on the piece letter by letter. This outline can be created with a soft lead pencil and using a set of 1/8 inch (3.17 mm) steel type.
Once all the letters have been applied, you need to place the steel letters on top of each of the outlined letters and then hammer the letter into the metal with a hammer. This process will create an indentation in the metal. This process continues until all letters, numbers and other designs are completed.
When finished, the process should have created a piece where the metal indentation is custom made. You can enhance the lettering by filling in the indentations with some type of colored polymer. This allows the indentation to stand out against the metal.
