RKP Deburring Plastic Media

RKP 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.

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

The appearance of the machine surface creates intuition for your customers. Do you want to give your surface an elegant emergence? Try tumbling your tools with Inovatec Machinery. Tumbling includes burnishing, deburring, cleaning, and polishing your machine surface. It gives your device a beautiful look and increases efficiency. It improves conductivity, increases solderability, and reduce corrosion. There are many tumbling media available: Ceramic Tumbling Media, Plastic Tumbling Media, Hardwood Tumbling Media, etc. It is imperative to get the right fit of tumbling media to meet your requirements.

Here, We will discuss Plastic Tumbling Media – One of the tumbling media Inovatec Machinery offers.

You may consider plastic as tumbling media ill at ease. However, it is a remarkable invention in the tumbling process of delicate metal parts. Tumbling Plastic media is lightweight abrasive media you can choose for finishing operations of light metals. It is better than any other ceramic media because of its low density. Conventional ceramic tumbling media exhibit a bulk density which damages delicate parts during finishing operations. Plastic tumbling media having a significantly lower bulk density could be beneficial to you. You may use the low weight tumbling media for refining or finishing delicate industrial parts. You may also apply plastic tumbling after you have tumbled it with ceramic media.

Polyester resin bonded plastic tumbling media uses resins and abrasives in equal weights. Plastic tumbling media consists of alumina, corundum, and zirconium, etc. Silica being bulking, pacifying, and suspending agent, it is used as an abrasive agent. The concentration and property of abrasive media used determines the finishing performance of plastic media. You can vary the cutting power of this media by changing the composition of abrasive and resin. The higher cutting power of this agent causes higher wear and tear of the media. The tumbling media twisted by this method may be cast into any desired linear symmetrical or nonsymmetrical shape. It is available in the pyramid, spherical, cylindrical, triangular, and elliptical shapes. You may cast it depending upon your end requirements. The parts which require delicate finishing uses this method of tumbling. Aircraft engine, structural components, automotive parts, golf clubs, jewelry, silverware uses plastic tumbling. Other conventional high-density media deforms and impinges those delicate parts. So, Plastic Tumbling media suits them best.

The deburring of metals like Brass and Aluminum uses Plastic Tumbling media. It gives more even finish than other conventional tumbling media.

There are many benefits to using plastic tumbling media. We have discussed some of its advantages in this article.

Features of Plastic Tumbling Media

  1. Smooth Surface Finish

Plastic tumbling media is soft, small, and light. The final surface obtained is flat with no vertical deviations from the ideal surface.  Smoothness in your surface determines the performance and durability of parts. The smoother your surface is, the less your machine parts wear and tear.

  1. Ideal for Soft Metals

The bulk conventional tumbling media may break soft metals like brass and aluminum. Lightweight Plastic tumbling media suits well for soft metals. It would help if you used it for soft metals because it avoids rolling the blur into the hole.

  1. Wide Variety of Shapes and Sizes

You can get the plastic tumbling media in various sizes because of its elastic constituent. It can be cast into a pyramid, spherical, cylindrical, triangular, and elliptical shapes.

  1. Medium Density Tumbling Media

Plastic Density Tumbling Media has a 40 % lighter weight than the ceramic tumbling media. It makes this media more convenient to use for a variety of applications.

  1. Short Cycle Times

Does the time taken in the tumbling process matter? Plastic Tumbling media has a short cycle time. It means it takes less time to finalize tumbling your tool.

There are many application of using Plastic Tumbling Media. Now, let’s discuss some of its applications:

Application of Plastic Tumbling Media

  1. Deburring Brass and Aluminum

There are many built-up burrs and other imperfection present at your machine parts. These burrs arise when you cut part of metal or plastic. Deburring means to remove these burrs and blemish. Plastic Tumbling Media removes the imperfections of Brass and Aluminum.

  1. Edge Rounding on Plastics and Other Materials

Edge rounding of your machine parts breaks the metal component’s edge. It improves its surface coating and helps in preventing corrosion. This method of tumbling creates a round tip on plastics and other material.

  1. Eliminating Machining Lines

The finishing parts consist of architectural finish lines that are uniform and directional. We remove these lines to give a pleasant look to your metal piece.

  1. Forming a light radius

The Plastic Tumbler has a smaller nose radius. It helps to withstand high cutting force created during parts finishing. It makes a bright finishing cut and improves surface finishing.

  1. Pre-Plate Finishes

Pre-Plate Finish includes passivation, polishing, buffing to your finished part. It improves luster enhancing Finish to your components. It makes your metal parts ready for electroplating. Electroplating gets your desired metal coated in your pieces. Aside from aesthetics, it helps in preventing corrosion, wear, and tear.

Size matters:

It is imperative to choose the suitable size of the Tumbling machine. The size will have an impact on the quality of your surface. So, be wise when you select the tumbling media.

To make you at ease, Inovatec Machinery bids Plastic Tumbling Media with several specifications and sizes.

We offer the following shapes of Tumbling Media.

  • Tri-star plastic media,
  • Parabolic Shape plastic media
  • Tetrahedron (pyramid) shape plastic media
  • XG cone-shaped Plastic Media
  • RPE cone-shaped plastic media 10 mm etc.
