RKE Deburring Plastic Media

RKE 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 sofer, has a lower density than preformed ceramic media, providesa cusioning 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 micrometers. 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.

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

 

Metal finishing takes different forms based on the type of metal used in the process. On our platform, one of the tumbling media you’ll come across is plastic tumbling media. If you’re new to metal finishing, you’re probably wondering how plastic can get used? After all, you are trying to finish a metallic part. However, tumbling media that’s plastic happens to be a preferred option within the finishing industry. That’s because it’s light and also has a much longer lifespan than other tumbling media. Read on to see how plastic tumbling media can create the metal finishing you’re seeking.

 

What is Tumbling?

For smoother finishes on mass-produced metal parts, the parts may need to undergo tumbling processes. Tumbling helps to make parts more manageable for different uses. For instance, the process could cause a given part’s jagged edges to become smoother. You could also use metal tumbling to prepare the part’s surface for other production stages. Whatever the case, metal tumbling makes it easier for manufacturers to produce their sought parts. The process also increases your machinery’s output speeds and overall lifespan. Having smoother pieces means your machines don’t get worn down by uneven edges. It goes on to improve your production activities as machine maintenance is limited.

 

How is Plastic Tumbling Media Made?

For this revolutionary tumbling media, we use a standard formula to keep the quality high. Our plastic media includes a polyester resin as well as abrasive compounds. To achieve the lightweight media, these get incorporated in a 1:1 ratio. There are a variety of abrasives which we use to create the final product. The abrasive added depends mostly on the amount of cutting power necessary for the task.

With our products, Silica is one of the most commonly used abrasive. However, depending on your preference, other abrasive materials may be added. These include corundum, zirconia, and alumina, to name a few options. The chosen media abrasive will determine the amount of cutting power achievable by the plastic media. It’s, however, essential to note that some downsides to having increased cutting power also exist. For instance, your media won’t last as long as expected with plastic tumbling options. That’s because it will get subjected to more wear to create the finished product.

 

Our Range of Plastic Tumbling Media

Depending on the purpose you’d like served, different media shapes will achieve that for you. That’s why we ensure you can choose your preferred media shape from our product list. Some of the available options in our catalog include:

  • Tri-star shaped media
  • Paraboloid shaped media
  • Tetrahedron or pyramid-shaped media
  • XG cone shapes
  • RPE cone 10mm shapes
  • Button shaped media

The differently shaped media can all produce desirable results with a vibratory tumbling machine. A vibrating machine allows the plastic media to brush against the metallic parts smoothly. So, whether you’ve got small or large pieces, they’ll all receive a perfect finish. The vibrating of the machine allows your items to get finished without any chance of damage. The safety gets further enhanced by the minimal weight of the plastic tumbling media.

 

Applications for Plastic Tumbling Media

When selecting your tumbling media, you must consider the effect you seek to achieve. For instance, if you need shiny surfaces, you would need ceramic media. Plastic tumbling media can polish your items, but it won’t create a polished finish. However, this tumbling media may get used later to prepare your parts for ceramic tumbling. Plastic tumbling media serves multiple purposes. You can use it for deburring light metals such as brass, zinc, magnesium, and aluminum. Metals tend to get jagged seams and edges due to shaping by industrial cutting molds. The process would help you get sharp edges off such parts with ease.

You can also use plastic tumbling media for finishing delicate threaded parts. When not deburring, this media can be used for surface cleaning of your various pieces. You would get a clean surface, ready for other follow-up production processes. These include activities like electroplating or even painting. In case you’re into 3D printing, this media will also work well with your products. Plastic media does an excellent job of burnishing plastic materials for a smoother finish.

 

Results of Using Plastic Tumbling Media

The shape chosen for your plastic tumbling media should work towards getting your desired outcome. Knowing which media shape will work for you is our company’s goal. We don’t just make the plastic media shapes you need. We can also advise you on which one will work most efficiently for your parts. Apart from the media shapes you choose, the size also plays a role in the end product. Below is a description of the purpose of some of our plastic tumbling media options. These depend on the shape and abrasive materials chosen for their creation.

 

  1. Z1 Zirconium Polyester Plastic Media

Adding Zirconium Silicate to the tumbling media composition creates a fast-cutting media. With such, you can get results faster on your items as they mimic ceramic media. The fast cutting action even enables you to accomplish deburring demands on your products. Some of the options available for clients in need of Zirconium plastic media include:

  • Tetrahedron shapes
  • Zirconium Polyester plastic media
  • Triangle shaped plastic media

 

  1. CX Nipple Shape Plastic Abrasive Media

Our nipple shaped plastic media gets its name from its signature pointed shape. You can order this tumbling media in one of the two available sizes. Its unique design makes it ideal for finishing items with deep holes in them. Apart from that, it can also deburr and prepare surfaces for more processing, such as polishing.
