Different Types of FRAS Plates Available at Online Plating Stores
The FRAS (Free RF Assembled Structure) is the acronym for Free Rotary Arrangement of Air Suspended Patterns. The plate has an open face like a baseball bat and the entire face is made of a rubber or plastic compound. This plate was designed by NASA Scientists and Engineers in the early 1960’s as a solution to the air shipping problem faced by the then-burgeoning space industry. These specialized plates were initially used on launches vehicles but after that day there were several other applications and by the end of the decade, it had assumed the position of the primary lifting device in all launches. The FRAS is so versatile that many other applications emerged which made the ceramic plates far more user-friendly.
These include carrying experiments in space
being a sensor for monitoring the condition of the ground, and several others. The plates have great sensitivity and have a very high tolerance against stress and they can even withstand extreme temperatures. The main advantage of this type of plated object is that they are very light in weight and hence they can be carried from one place to another very easily. They are also very versatile because they can be used with a wide variety of materials.
One of the most common uses of the FRAS plated objects
is to act as a sensor for the moisture level in the atmosphere. This is because the material has excellent reflectivity and thermal insulation properties. So the temperature inside the plate will be easily reflected back and hence you get an accurate reading of the moisture present in the soil. Other than this, the material also exhibits antibacterial and anti-fungal properties and hence they are used in the manufacturing of artificial grass and even soil. If you are planning to use the FRAS plates for any of the above purposes then there are certain important factors that you need to keep in mind. First of all, you need to buy high-quality ceramic plates which are manufactured by reputed companies so you get good quality output.
You should check that the length of the plate
is accurate because an inaccurate measurement can lead to a lot of problems. The other factor that you need to check is the thickness of the plate. You should buy a plate that is not more than 0.5 mm thick because higher thickness leads to an increased cost of production. It is always better to buy ceramic plates that are produced using laser technology because they offer a lot of benefits.
The latest technologies used by the manufacturers
in producing the plates include laser melting, laser tumbling, direct metal arc welding, and press brake tumbling. If you want to buy a plate that has high reflective properties then you can buy a plate that is coated with lead sulfide. This plate is coated with lead sulfate before being sent for plating. This coating makes the plate highly effective in reflecting infrared rays.
Another important feature that you should check is dimensional stability.
You should always buy a FRAS plate that has a nominal dimensional stability value of more than 0.90. This means that the plate should not move much while being used. This feature prevents the plates from breaking or twisting when used.
