RKG Deburring Plastic Media

RKG plastic media is preformed plastics, the other workhorse media, are also available in a variety of grades or bodies, with some manufacturers having nine grades while others have as few as three.

This media is formed by bonding abrasives (generally 40-70% by weight) into polyester, usually by casting. After casting, this media is typically pre-tumbled to remove flash. The plastic media is softer, has a lower density than preformed ceramic media, provides a cushioning effect, and sometimes has a shorter life. It is well suitable for finishing softer metals and fragile parts, achieving pre-plating requirements, and producing smooth finishes as low as 5 micrometres. During finishing the matrix which is softer than the abrasive, is eroded, leaving the abrasive to perform the desired work, While some users believe it assures parts free of impingement, this is not ture, All the mass finishing processes expert for fixtured or compartmentalized operations allow part-on-part contact. Plastic media can also be produced in a wide variety of desirable shapes. In practice over a decade some shapes go out of favor and new ones emerge.

Inovatec noted that the plastic media provides no surface hardening of the workpieces. In addition, plastic media is also quiter than abbrasive chips.

 

INTO THE WORLD OF THE PLASTIC TUMBLING MEDIA: ALL THAT YOU NEED TO KNOW

If you are into mass finishing, it could only be for three basic reasons; to achieve coeval finishing of many small components in as little time as possible, to achieve a fine appearance and durability, and also to reduce the cost of production. Achieving all of these is dependent on a lot of factors, with one chief amongst all and that is the type of tumbling media you use for your finishing. There are different types of tumbling media but today we will be focusing on the plastic tumbling media.

MEET THE PLASTIC MEDIA

The plastic tumbling media is just like every other tumbling media: a consumable used in mass finishing to achieve the finishing touch that would set your product apart. The difference is just this:  plastic tumbling media, is composed of equal fractions of polyester resin and abrasives. While silica is the most common abrasive used in the creation of plastic media, alumina, zirconia, corundum, amongst others can be used as abrasives for creating plastic media. The nature of the abrasive used in the creation of plastic media will determine its finishing performance, as well as its wear rate. The plastic media is also very light weight, weighing forty percent less than it’s ceramic counterpart.

CLASSIFICATIONS OF PLASTIC TUMBLING MEDIA

Plastic tumbling media can be classified using different sub categories; density, shape and size. The differences in density, shape and size all serve different purposes. You can be sure to always find a plastic media for your specific need.

Density

Under density, we have the High density and low density media. The high density media produces quicker and better finishing than the Low density media. The high density media also wears off faster than the low density media.

Shape

Plastic tumbling media is made into different shapes to fit into use in different case scenarios. While the tristar shaped plastic media can be used in very small and narrow areas of parts, the nipple shaped plastic media can get into those deep holes without any difficulty. Each of the available shapes can prove very useful in the right case scenario, making mass finishing more of a joy than usual.

Size

Parts come in different sizes. That is why plastic media also comes in different sizes, making mass finishing a very convenient process. You don’t have to split the woods with the knives or cut the bread with the axe. There is always a plastic media of the right choice for you.

 

WHAT THE PLASTIC TUMBLING MEDIA CAN DO

You can use the plastic tumbling media to carry out a lot of mass finishing tasks. With the plastic media, you can achieve metal removal, pre-plate finishing, moderate cutting,

  1. For soft metals

When working on soft metals, the plastic tumbling media is the best option to use. If your work involves metals like zinc, aluminium, brass, or any other soft metal, then it would be favourable to use the plastic media as it would yield the best of results. No matter the kind of task you are trying to carry out on these soft irons, you can be sure of the plastic media to get the job done.

  1. For fibrous and stringy materials

If you are working on fibrous or stringy materials that need to have a very neat and smooth surface, then it would be very wise to make use of the plastic tumbling media. You would love the result that follows.

  1. For anodizing

If you are going to be anodizing a soft metal like aluminium, it is much more advisable to use the plastic tumbling media. It leaves a good surface for you to do your coating.

  1. for even surfaces

The plastic tumbling media is the choicest if not the only media when it comes to achieving very even and smooth surfaces. You want a finishing that will not gleam? Then use the plastic tumbling media. You will achieve those even surfaces that you seek.

 

BENEFITS OF USING THE PLASTIC TUMBLING MEDIA

Everything comes with its own kind of advantage and reward. Using the plastic tumbling media is no exception to that rule. These are the reasons you should consider using the plastic media.

  1. speed

The plastic tumbling media can get jobs done faster , thus helping you achieve more in no time.

  1. Safety

The plastic media is safer to use than the other kinds of media as it releases little or no chemicals during use

  1. Ease and convenience

The plastic tumbling media is a much easier and convenient choice when compared to all the other choices available.

  1. Little or no wearing

Since the plastic media does not wear out like its ceramic counterpart, it is a better option to use in parts with holes or crevices. This totally solves the work piece piece logging issues that usually occur when the ceramic media is used.

  1. Reduced energy consumption

There is lesser energy consumption and release when the plastic media is used. If that is something you would love to achieve, then this is the media for you.

  1. Quality finishing

Smoother surfaces are the trade mark of the plastic tumbling media. It is known to produce very smooth surfaces with reduced gleam.

  1. Better surfaces for painting and coating

You can achieve surfaces more suited for painting and coating when you use the plastic tumbling media to achieve finishing.

  1. Lighter media

It is way lighter than the other kinds of media, making it cheaper and easier to transport. I mean, your job just got more comfortable. This also makes it more suitable for some very specific and sensitive jobs.
