Friends in the field of film coating know the film coating machine, but also know that the film coating machine is a platform equipment to replace the manual automatic scraping film, and know more about the accuracy and thickness of the film is mainly not controlled and determined by the film coating machine, but by the matching line rod or scraper to control the film thickness
From this point of view, the film coating machine is a film coating equipment to scrape the film by controlling the speed and pushing the wire rod/scraper, the principle is very simple, almost like that, to choose a high-precision wire rod or scraper is OK. However, the coating machine you think is not what you think.
The above film coating machine equipment figure 1, perhaps you see is: is a wire rod adjustable scraper film coating machine, glass platform, control panel, switch, fixture, it looks OK, but in the end, it is almost like that, many are who’s low price we find who.
Today,we will take you to explore what is behind a truly high-precision and high-efficiency coating machine.
The ultimate purpose of coating proofing is to test product quality or optimize product quality through testing. The accuracy of a coating sample has a great impact on subsequent detection, especially for new materials and high-end precision industry products. For experimental technicians, the requirements of film proofing are nothing more than high-efficiency proofing and high-precision film production.
First, a good film coating machine is able to let you really efficient proofing.
If you choose to use a coating machine instead of proofing, at least you are doing the first step in solving the problem of coating efficiency. Then, the next step you will encounter new efficiency problems, the installation efficiency and cleaning efficiency of the film applicator.
Zoom in on the detail above and take a look at this device. Efficient coating machine design is really standing in the user’s point of view to design: 1, clip type wire rod installation, on the one hand installation and disassembly is very simple, on the other hand, this installation method greatly reduces the line rod loading and unloading may cause wear.

2, clamshell scraper design cleaning is no longer a more confusing problem for the scraper coating, for the fixed adjustable scraper, cleaning up a lot of high efficiency and without losing the stability of the fixed drum scraper.

3, the fixture on the right of the fixed substrate is also a hidden trick, the built-in spring, the fixed substrate is also more efficient, a few simple twists can be clamped (without details here).
Did you compare the details?
Second, the best coating machine is to ensure high precision coating in all aspects
Everyone who knows about the film coating machine knows that high-precision film coating must be equipped with high-precision film coating equipment, such as imported wire rod coater and scraper with higher accuracy value. So, is that enough? Just like, a computer, the CPU is the core, a good CPU will definitely run faster. But doesn’t the hard drive matter? Does the memory size not affect it? Does the network and hardware not affect it?
So the coating machine you think is really not so simple. The film coating machine is the same, the accuracy of the film coating machine is the key, but the flatness of the film coating machine itself, the precision of the thickness control of the scraper, the stability of the motor operation, the flatness of the substrate fixed, and even the level of the adjustment of the whole equipment will affect the accuracy of the film.
Then enlarge the above film coating machine equipment figure 1 to see. The black glass plate above is selected from the 3C certified national standard authentic high flatness gold crystal original sheet of high temperature toughened glass plate, to ensure the accuracy of the flatness of the film platform.
Then shift your gaze to the adjustable scraper on the right. The differential regulator that controls the thickness of the scraper is a product of a trusted brand. The following scrapers have been tested for accuracy by professional precision measuring equipment and come with a certificate.
In addition, we can not see, the motor selection of the equipment, the stability of good motor operation is relatively high, and the accuracy of the film is also affected. For a simple example, if the motor vibration is more obvious, the scraped film will have a ripple, or the scraping thickness is not uniform. This is why experiments that require higher film accuracy will choose a higher price servo motor.
All in all, the coating machine is not a simple control of speed and pressure, and then push the coating machine to scrape the coating so easy to obtain high-precision film samples. One can’t make bricks without straw, and then senior technical experts, also need a good tool to help. There is such a truth in the field of testing instruments: the quality level of the testing equipment you use often can see the quality level of your product. Therefore, in the limited range of budget, it is ideal to choose more cost-effective equipment. I hope this article will inspire you in the choice of coating machine equipment.
