There is a vast growth in demand for foam cutting nowadays, especially for fabrication and machining. The demand for foam cutting and machining is essential in various types of industries, including props, sculptures, signs, monuments, displays, prototypes, architectural shapes, crown moldings and wall caps for construction, packaging insulations, wings and so much more.
Companies cutting foam need to use top of the line cutting equipment to offer a wide range of foam cutting services. The cutting can be done either by using a
The smaller foam cutters will usually cut wings, fuselages, logos and letters. The medium foam cutters will cut similar shapes to small ones, with the addition of being able to cut crown moldings and trims used in the architectural industries, while the large foam cutting machines are used mostly by construction contractors and large sign manufacturers.
The laser cutters and engravers can cut Polyurethane, mainly for packaging, insulation and gun cases; Polyethylene or EVA foam For 3D shapes, packaging and tool trays; Polystyrene for packaging, crown moldings, signs and props; Polycarbonate (also known as Plexiglas) for cutting and engraving and MDF for vacuum molding forms. If the materials to be cut are wood or light metals, the use of a
The different cutting machines differ in their dimensions and size, including their effective cutting on the X axis (horizontal) and the Y axis (vertical), their hot wire length, and other features such as cutting speed capabilities, how many blocks of foam can be cut in one single cut and the type of cuts made (tapered or not tapered).
For projects requiring machining foam or fabrication of foam there is a need to use
The process of cutting the foam involves specialized files that include the shape drawing. For 2D shapes a DXF file is required, while for 3D shapes an
Once the right file is received, the data is entered into the computer which is connected to the foam cutter, including all the coordinated needed for cutting that specific shape. Upon finishing of cutting the shape needed, it can be sanded to either a rough or a smooth finish, according to the customer’s request. Large scale shapes are made in several pieces, then glued together to make the complete shape. The cut can also be coated with Polyethylene coating, Polyurea and paint it if needed. The end product needs to be durable, strong and long lasting.
