Although CHINA has become accustomed to the 9.4mm diameter RDS wire-wound scraper, there are still some customers who have asked about the 6.35mm diameter scraper because their products are exported overseas, especially in Southeast Asia. In addition, since last year, due to the needs of some customers, NBCHAO has introduced RDS molding rods (extrusion scraping rods) earlier. Up to now, the author has not heard of other domestic channels selling molding rods. This can be regarded as giving users a variety of choices.
Not much nonsense, RDS currently has four main types of scraping rods in CHINA: 3/8 inch, 1/4 inch, 1/2 inch wire wound scraping rod and 1/4 inch diameter formed scraping rod. What do they look like? NBCHAO provides the following groups of photos, all of which are professionally taken by NBCHAO to give users a more vivid and comprehensive product impression.
<1> This is a group of real pictures of RDS scrapers covering the above 4 diameters and crafts. The difference can be easily seen from the red soft rubber cover.
<2> Let's look at it from another side. RDS scraping rods with different diameters are also obvious from the comparison of the stainless steel main rod.
<3> The author took a Nikon D7100 camera, and the lens was chosen very well, but unfortunately, for a relatively small number, because the steel wire is too small, there is no way to clear it, so I can only take a model with a few tens of microns Only then can you take a clear picture.
<4>The following are 2 RDS scrapers with a size of less than 10 microns. You can see that the steel wires are not clear. The North and South Tide made the same joke twice when selling RDS scratch sticks. The customer bought the No. 3 scraper, but it turned out to be a fake because the steel wire could not be seen. In fact, the steel wire diameter of the No. 3 scraper is only 0.08mm, which is as thin as a hair. In addition, the craftsmanship of RDS is very good, so it is already difficult to distinguish with the naked eye. Of course, let the customer look in the magnifying glass later, and the problem will be solved. From being disdainful to us at the beginning (depressed why not RDS), to admiring the exquisite craftsmanship of RDS later (even more depressing why not praise the north and south tides? Why is it always me who gets hurt?)
<5> Different processes, different diameters and even different model batches have different wire winding interfaces for RDS. Please pay attention to this. We have also specifically consulted the supplier on related issues, and made clear reminders on all RDS product pages regarding interface issues.
<6> I believe everyone is familiar with the scraping rod of wire wrapping. After all, as a traditional Myler rod, its craftsmanship has long been recognized by the industry.
<7> The picture below is a group of extruded molding rods taken by a beautiful colleague from NBCHAO. There is no such thing as an interface for RDS extruded molding rods. We have also done detailed research on forming rods and wire winding rods. There is no difference between the two in actual use and can be replaced. The difference is that the U-shaped groove of the extrusion type is clear and easy, and the V-shaped groove of the wire-wound type is more in line with the Mayer-Bar principle. Another difference is the possible difference in the amount of coating between the two. After all, the shape of the groove is different, which should be It's easy to understand. For some manufacturers who advertise that the winding wire is easy to break, this is almost immune to RDS, and related questions can also be found in the North and South Tide knowledge base. Complete answers.
<7> The picture below is a picture I personally like more, and the winding wire is also taken clearly. The important thing is that there is NBC behind it. Do you know what NBC stands for? ——The pinyin initials of the North and South Tide! Haha~
<8> The following picture is a real photo of the scratch-coated paper after coating and drying in the laboratory of the North and South Tide. Due to the lighting and camera during the experiment, we cannot bring you a picture under the wet film, so we have to take this dried one. Let's shoot. But what is certain is that the shooting in the wet film state is undoubtedly more textured than the dry film state, after all, there is water on the coating.
This is the end of our introduction to RDS in this issue. In fact, we have typed so many words in order to present you with a set of clear pictures. For those who are more impatient, I hope you will forgive me!
