Use of ultrasonic knife in plastic modelling

"Cuts plastic like butter"

 

The Japanese company Echo Tech started supplying ultrasonic cutter ZO series to the hobby market in 2001. In another 5 years, its second generation came, and then the third in 2012. However, they were still products intended for the Japanese market. It was only in 2016 that the production of the current ZO-91 model, which is sold worldwide, began. As a next step, the new ZO-95 model was put on sale in 2020. 

Most knives are manufactured by Honda Electronics.

 While the ZO-91 model is intended for hobby use, the ZO-95 type is intended for professional use. Of course, the principle is the same for both types. The blade oscillates at a frequency of 40kHz, most of the blades in the offer are suitable for use with both types. So what is the difference between the two products? By way of execution and control. The most important differences are the following: ZO-91 has 2 levels of power available, ZO-95 has 3 levels. The ZO-91 has a power switch located on the handpiece, while the ZO-95 has a foot switch. Another difference is the cutting time setting. Since the device heats up quite intensively during operation, in addition to the thermal fuse inside the unit, the software limits the operating time according to the power used.

 Thanks to the wide range of blades offered, the knife can be used for a variety of tasks.


Cutting

- This is the basic function of a knife. In addition to standard blades, special blade designs are also available. In addition to the extra thin blade, there is also a cemented carbide blade and a zirconium ceramic blade. In addition to plastic, the knife reliably cuts resin, 3D prints, thin laminate, cardboard.

 

Engraving

- Another interesting option for modellers is a chisel replacement head.

 

Grinding and polishing

- with special flat or rounded attachments with 80 to 1200 grit designed for grinding hard surfaces.

 

Welding

- joining vinyl strips with a welding attachment.

 

It is interesting to see where the knife is already being used. Of course, the knife is widely used in model making. Not only plastic, but when building RC models, making dioramas and creating figures.

Manufacturers of prints on 3D printers are leading to a large expansion of knives sales. Removing supports is easier and significantly faster. With a knife, you can quickly remove the print from its supports, so there is not much left for the final sanding.

Grinding is used in the production of molds, even in dental laboratories for dental prosthesis production.

In Japan, where the use of ultrasonic cutter ZO series is most widespread, the knives have also found their way into museums, where they are used, among other things, to clean petrified fossils.

 

What are the advantages of using a knife in plastic modeling? Easier separation of parts from sprues. If the modeler is skilled enough, he can separate the part in such a way that there is no need for more sanding. For weak and thin parts such as antennas, it is possible to separate the part without subsequent grinding. It is possible to separate parts even from fragile plastic without the part falling apart, which may happen if you use pliers or a saw.

The knife is priceless if you build resin kits or use resin accessories. Long cuts with a razor saw with a large amount of sawdust are eliminated. You are able to work the casting perfectly with a knife, so there is no need for long grinding. The time saving is considerable.

Another advantage of the knife is that if you happen to glue a part incorrectly, thanks to the knife, in many cases you'll be able to correct the mistake very easily.

Video showing the knife used by Zdenek Šebesta you can find on the YouTube channel Plastic modeling.

You can find other videos of the use of EchoTech products on their YouTube pages and other social media.

Good day, Dear Friends After the February premiere and the March sequel of the P-40E, it's time for what was probably the most significant foe of the Warhawks, the Japanese Zero. The last new release of a member of the Zero family, the Rufe float version, was exactly two years ago, in April 2023.

KAMIKAZE TOKKŌTAI

KAMIKAZE TOKKŌTAI

One of the most well-known words from the field of aviation, recognized even by those with no interest in the subject, is kamikaze. It is associated with the predominantly aerial campaign that began in October 1944 and lasted until the end of the war in the Pacific. During this period, hundreds of airmen sacrificed their lives in service of the Japanese Empire.

Dekelia Greek Air Force Museum

Dekelia Greek Air Force Museum

The Hellenic Air Force Museum is a relatively young institution, having existed in its current form since 1986. However, it certainly has a lot to build on, as its aviation collections were previously part of the Hellenic War Museum. The museum is organisationally under the Hellenic Air Force (HAF) administration and its mission is not only historical research, collection, preservation and access to exhibits, but also the retrieval, conservation and restoration of artefacts related to Greek aviation history.

Like a Painting on Canvas

Like a Painting on Canvas

Market Garden was the largest Allied airborne operation of World War II, launched on 17 September 1944 in the Netherlands. Its objective was to use paratroopers (the "Market" component) and the rapid advance of ground forces (the "Garden" component) to seize key bridges over rivers and canals, thereby creating a corridor for an attack into Germany. However, the operation ultimately failed due to strong German resistance, poor coordination, and delays in the Allied advance, particularly at Arnhem, where British paratroopers were unable to hold a crucial bridge.

Tail End Charlie - Almost an April problem

Tail End Charlie - Almost an April problem

It's not entirely my fault that I’m writing my Tail End Charlie text at the last-minute again. I scheduled my work quite responsibly yesterday, Sunday, two days before the current issue was due out. However, somehow I didn't keep up at the end of the day. Understandably, I could blame my slow work, my tendency to run away from responsibilities, orstimuli that release the right hormones into my brain for the wrong mood, and a thousand other things rooted solely in my nature, irresponsibility, and laziness. But this time it's different my friends.

P-40E Warhawk

P-40E Warhawk

The Curtiss P-40 line of fighter aircraft stood out among American fighter types for having remained in front-line operations from the summer of 1941, before the U.S. entered World War II, through the end of the conflict four years later. Only Grumman’s versatile F4F Wildcat naval fighter could match that record.
