This text sheds gentle on why to chop foam, which makes use of are there for slicing foam, the forms of industries utilizing foam cuts and what’s the means of slicing. It additionally explains the forms of foam used and the tools concerned within the course of
There’s a huge progress in demand for foam slicing these days, particularly for fabrication and machining. The demand for foam slicing and machining is crucial in varied forms of industries, together with props, sculptures and monuments, boats, kayaks and canoes, indicators, shows, proto varieties, and architectural shapes, crown moldings for development, packaging insulations and wings.
Corporations slicing foam want to make use of prime of the road slicing tools to supply a variety of froth slicing providers. The slicing could be finished both by utilizing a CNC sizzling wire foam cutter, or a CNC laser cutter. The new wire can minimize virtually any thickness of froth, and as much as 12 ft tasks and extra; Whereas the laser cutter is cable of slicing very skinny cuts (as much as ¾”), manufacturing a high-quality floor end. The choice of whether or not to make use of the laser or the new wire cutters relies on the kind of foam (for instance, Polyurethane, also called PU foam can solely be minimize with the laser), on the thickness and the dimensions of the froth to be minimize.
Most CNC sizzling wire foam cutters are able to slicing EPS foam (additionally referred to as Expanded Polystyrene), EPP foam (referred to as Expanded Polypropylene) and XPS foam (Extruded Polystyrene).
The smaller foam cutters will normally minimize wings, fuselages, logos and letters. The medium foam cutters will minimize related shapes to small ones, with the addition of having the ability to minimize crown moldings and trims used within the architectural industries, whereas the big foam slicing machines are used principally by development contractors and huge signal producers.
Laser cutters and engravers can minimize varied forms of foam, together with Polyurethane, primarily for packaging, insulation and gun instances; Polyethylene or EVA foam for creating 3D shapes, packaging and power trays; Polystyrene for packaging, crown moldings, indicators and props; Polycarbonate (also called Plexiglas) for slicing and engraving and MDF for vacuum molding types.
If the supplies to be minimize are wooden or gentle metals, the usage of a CNC router is critical.
The completely different slicing machines differ of their dimensions and dimension, together with their efficient slicing on the X axis (horizontal) and the Y axis (vertical), their sizzling wire size, and different options reminiscent of slicing pace capabilities, what number of blocks of froth could be minimize in a single single minimize and the kind of cuts made (tapered or not tapered).
For tasks requiring machining foam or fabrication of froth there’s a want to make use of CNC routers or a combo of a CNC sizzling wire foam cutter with a router system. Full scale racing vehicles, 3D topographic maps (as much as 10’x5’x20″ on a single minimize), props and artwork work can all be machined, and foam molds may also be created.
All the slicing machines are CNC, which implies they’re managed by a pc and include specialised slicing software program.
The method of slicing the froth includes specialised information that embrace the form drawing. For 2D shapes a DXF file is required, whereas for 3D shapes an STL file is required, which permits to rotate the form and see all of the angles of it for higher accuracy.
As soon as the correct file is acquired, the info is entered into the pc which is linked to the froth cutter, together with all of the coordinated wanted for slicing that particular form. Upon ending of slicing the form wanted, it may be sanded to both a tough or a clean end, in keeping with the shopper’s request. Giant scale shapes are made in a number of items, then glued collectively to make the whole form. The minimize may also be coated with Polyethylene coating, Polyurea and paint it if wanted. The tip product must be sturdy, robust and lengthy lasting.
