Automated Ultrasonic Cutters are special purpose machines used for cutting and edge sealing synthetic fabric.

Aeronaut automated cutters offer production speeds which are 3-4 times better than conventional machines. Typically, when cutting with most ultrasonic cutters, only one edge of a piece of fabric is cut at a time… the fabric is rotated by hand, and other edges are cut. These simple machines offer the efficiency of a motor driven utility knife… that is, no better than cutting with a hand held tool. By comparison, Aeronaut cutters will cut all sides of a piece of fabric in the one operation, resulting in a close to 400% increase in efficiency.

And of course, Aeronaut Ultrasonic cutters can cut more than just plain rectangles. And because when you cut on a full Aeronaut vacuum bed cutting table, you can cut more than one pattern without moving the fabric, and many patterns can be nested into a single "table" or frame, not only is the production speed increased, but fabric waste and mistakes are reduced by a huge amount. 

Aeronaut Ultra machines can also be used for Crush Cutting.

Because of the hard table surface, it's possible to extend the Aeronaut Ultra machines by fitting optional high pressure crush cutting components and a crush cutting tool so fabrics which don't lend themselves to ultrasonic cutting can be crush cut on the same table. Since all four sides of the fabric are cut in the same operation, you can expect the same accuracy and productivity increases which are offered by any Aeronaut cutter.

Aeronaut manufactures ultrasonic cutting tables to suit all needs and budgets from the single steered tool Elektron B1 Ultra to the two tool Elektron B2 Ultra. Both machines feature Aeronaut's unique bayonet tool holders. The tool holders allow 10 second tool changes, so you can not only fit ultrasonic tools, you can also fit any of Aeronaut's other bayonet tools from creasers to reciprocating blade cutters.  

Given a productivity increase of better than three times, reduced mistakes, reduced stress and big fabric savings, and given that the cost of an Aeronaut system is only a little more than these primitive machines, why settle for anything less than an Aeronaut Ultrasonic cutter!

Aeronaut Ultrasonic Cutters are mechanically very similar to standard Aeronaut cutters… only the cutting tools and table top are special. Because of this, it is possible to have a dual purpose machine which can cut both with a rotary blade on a plastic table top, and on another section of the table with a metal table top, ultrasonic tools can be used giving unmatched versatility as well as a big jump in productivity compared with conventional manual cutting tables.

It's also possible to fit the Elektron B2 Ultra with different shaped ultrasonic tools in each holder, so different weights of fabric and be cut and sealed with software driven automatic tool selection. 

Ultrasonic cutting is common in the manufacture of window furnishings, window shades or blinds where a turned-over hem is not acceptable and a clean, fray-free edge is required. In many cases, this edge finish can be achieved using a rotary blade cutter but on many synthetic fabrics where edge sealing is required, ultrasonic cutting can be the best choice.

There are technical fabrics which simply cannot be clean cut with lasers or blades. and ultrasonic cutting may be the best solution. 

Ultrasonic cutting is not suited to all materials. Ultrasonic cutting works like this: High frequency sound energy is generated inside the cutting tool and focussed at the cutting tip. The tip rapidly vibrates or oscillates. This generates a lot of heat in most synthetic materials and melts the fibres which are parted by the tip of the tool.

For an ultrasonic tool to work, the vibration at the tool tip must be opposed by a hard surface. On simple hand-held ultrasonic cutters, an "anvil" is fitted below the cutting tip. The tip sits on one side of the fabric, and the anvil goes on the other side. Obviously this is not a very good idea for automated cutting, so the solution for automated cutting is to fit a hard metal surface to the vacuum table in place of the anvil.

It's also possible that with some non-synthetic material, that the ultrasonic action may saw through or fatigue fibres which cannot actually be cut. This explains why some materials like Kevlar and carboard can be cut with ultrasonics even though they don't actually melt.

The cutting tool can be shaped to suit different processes. A sharp tool will give a good cutting action with less sealing than a more rounded tool tip, but the rounded tip will probably give a better seal. 

The shaping and choice of tool tips for any particular process or fabric is a highly specialised procedure and an amount of trial and error can be required to get the best results.
