How To Put A Foam Saw Into Use

By Walter Thomas


Polystyrene foam is a lightweight material that is majorly used for personal projects such as arts and crafts or for commercial purposes in the construction industry. A tool that is used to cut the polystyrene material or other related materials into the required size is known as a hot wire foam saw. This tool is made up of a thin metal wire that passes through the material that is to be cut.

The tool goes through a two hundred degree electrical resistance to make it hot enough therefore termed as hotwire. The first type of wire is the preformed wire that is achieved manually or through fixture with hand pliers. The second kind of wire is the tensioned type held tightly to a bow or frame.

The materials commonly used by the cutter are the ones that easily melt as soon as they get in contact with low temperature making them efficient. Some of the materials include the expanded polystyrene materials white in color, the extruded polystyrene present in several colors and the polyethylene foams that are tear resistant. Furthermore, the materials that prevent fires in the fuel tanks and the ones that prevent shock are the right ones too.

An operator can manually use the preformed wire to create different sizes and shapes from the blocks of materials present. However, the tensioned wire can be used in five different ways with the manual use being the most basic one. The second method that the tensioned wire is used is by the addition of a horizontal table to place the good. This second technique is commonly used in the building and packaging sector.

In addition, the cutter can be used with a table that is guided with a template. This method is often appropriate in achieving accuracy in creation of models. The level of accuracy depends on the skills of individual working on the material. The level of precision placed on the templates also determines the accuracy of the results produced through guiding the wire to cut the material.

The fourth way through which the hot wire can be put into use is through the computer numerically controlled stages. The wires are guided to cut through the material by use of computer systems that are located on both sides of the material. The application of lathe attachments in the computer numerically controlled systems give the chance for creation of spiral shapes.

The final method known as the push through slicer is another way that the tensioned wire can be used in the design of foam. The tensioned wires are placed in parallel manner on the vertical or horizontal frame to enable cutting. Once a block of material of passed through the wires, several sheets of that material are produced.

The saw needs to get maintained at an appropriate temperature along with the appropriate limits of lengths of the wires that are positioned on the bars. Proper upholding of these requirements allow the production of right sizes and shapes in all areas. These areas range from the aircraft designs, the architectural industry and the construction of surfboards.
