A hot wire foam cutter is a special piece of equipment that is used for foam cutting. One example of materials this machine can be utilized to cut is polystyrene foam. It has various components which include a taut metal wire which is thin and is heated via electrical resistance for it to cut through materials. Depending on the make of the machine, the temperature of foam cutting wires normally reaches 200 degrees Celsius or more.
The wire can be made from various materials, but in most cases, it is made from stainless steel or nichrome. The wire can be pre-formed into any shape that one wants to produce. The wire is usually very hot that it does not need to make contact with the material in order to cut it. The material is vaporized prior to making contact with the wire.
A bow or frame with springs can be used to tension the wire. Most individuals have a tendency of preferring a single stainless steel wire strand to nichrome wire if the diameter is supposed to range from 0.008 inches to 0.020 inches. This diameter is appropriate for frame-tensioned cutters. A nickel-based alloy wire Rene 41 is usually preferred for commercial applications. The reason why nickel-based alloy is preferred is that its tensile strength is maintained at cutting temperatures.
This machine is appropriate for cutting several different materials. It is specifically appropriate for cutting through any thermofusible expanded foam. These refer to materials that normally melt at moderately low temperatures. Custom materials, flexible expanded polypropylene foams, polymathacrylimide, extruded polystyrene, and expanded polystyrene blocks are some of the materials that this machine can cut.
There are several types of these cutters in use today. They include performed wires, handheld devices, simple manual cutting tables, template-guided manual tables, push through slicers, and computer numerically controlled cutters among others. Preformed wires are usually attached to handles and the operator has to guide them manually in order to cut. They are utilized to cut free shapes. Handheld cutters also operate in the same manner where the operator guides them manually to cut freehand shapes.
A horizontal table is used in securing foam work pieces in place when using hot wire foam cutting tables. The wire, either vertical or horizontal then cuts through work pieces placed on the table. These vertical wires are used by hobbyists for cutting small but sophisticate shapes such as letters. Only prismatic members can be cut using vertical tables.
Horizontal tables are mostly used in the packaging and construction industries. Tracks are contained on the sides of the table and they are used for holding the wire. The wire can be moved with great precision due to the tracks. Both downward and upward motion is allowed for by the track. Also, horizontal tables can produce angular cuts.
These days, CNC capabilities have been introduced into foam cutting. This increases the ability and accuracy to cut very intricate shapes. Nevertheless, accuracy of CNC machines may be affected by factors like stepper motors, backlash of the drive systems, and rigidity of races used for supporting effectors. End effectors are normally used to hold tensioned wires.
