Product Description
Plastic media is used for surface polishing treatment. Through the vibration, centrifugal movement, eddy current rotation, drum rotation and other ways of grinding machine, so as to drive the polishing media and products tumbling together. Finally, it help you to achieving removing burr, flash, oxide layer and rust spots on the surface of the products.
Plastic tumbling polishing medias are mainly composed of resin, abrasive particle and additives. The resin acts as a binder to hold the abrasive particles together. Commonly used resins are phenolic resin, epoxy resin, polyester resin and so on. Common abrasive particles are alumina, silicon carbide, diamond and so on. The abrasive particle size is larger and the content is higher, the deburring force is greater. Additives are used to improve the performance of resin abrasives, such as increasing hardness and improving wear resistance and cutting performance. However, it should be noted that the cutting efficiency is higher, the wear resistance of the abrasive is lower and the wear rate is higher.
The service life of plastic abrasives depends on different application and there is no standard wear time. If you find that the grinding time increases, the polishing effect is not good, or when the polishing machine hole is stuck or the joint is blocked, you must replace the new abrasive or reconsider the polishing plan.
At present, we still keep manual injection molding, stripping, screening and packaging. The plastic media shape is more complex and abrasive and the size is smaller, the more manpower is needed and the loss of raw materials is greater. So the overall cost is also higher. Manpower, mold, raw materials, transportation are the four important elements of plastic abrasive pricing. Therefore, Nordern machinery factory not only produces and sells abrasives, but also supplies grinding machines, grinding additives (brightener/grinding fluid/cleaning agent) and other products. Our plastic polishing abrasives supply chain is well established.

Feature
1. Efficient Surface Treatment
Quickly removes burrs, flashes, oxide layers, and rust for a smooth finish.
2. Versatile Compatibility
Works with vibratory, centrifugal, tumbling, and rotary polishing machines.
3. Long-Lasting & Cost-Effective
Self-sharpening design ensures consistent performance, The grinding loss is only 40% of that of ordinary grinding stones.
4. Gentle Yet Effective
Flexible resin-bonded abrasives prevent scratches on delicate or complex-shaped surfaces.
5. Reduced Noise & Vibration
Smoother operation for a more comfortable working environment.
|Why Chooes Our Plastic Polishing Media?
❌ Manual processing = High labor costs & material waste?
→ Our automated-friendly media minimizes manual handling for better efficiency.
❌ Inconsistent polishing results?
→ Precision-graded abrasives ensure uniform finishes from rough to mirror polish.
❌ Frequent abrasive replacement?
→ Optimized resin-bonded formula extends lifespan while maintaining cutting power.
❌ Machine clogging or poor finish?
→ Our abrasives resist clogging and deliver reliable performance.
|Application Video
Plastic medias are widely used in surface treatment of various parts because of their elastomer properties.
1. Metal Industry
– Deburring stainless steel, aerospace parts, and precision tools.
2. Optical Industry
– Ultra-fine polishing for lenses, prisms, and camera components.
3. Stone & Carving
– Enhances marble/granite texture and gloss without damage.
4. Electronics
– Removes oxidation from PCBs, improves conductivity & solderability.

Size Information
Plastic medias are mainly conical shape, triangular pyramid, quadrangular shape, bullet shape and other standard shapes. It can be made into different specifications, such as different diameters, thicknesses, etc., to adapt to different sizes of products and polishing machines. You can also customize other shapes according to the shape of the part.
The shape and size of the plastic polishing media will affect the grinding result. Small size medias have small contact surface with products and the polished surface will be smoother and more delicate. The large size medias have stronger cutting ability. Conical and pyramidal shapes are the most common. This kind of abrasives top is small and the bottom is large, so it generally does not stick into the slots and holes of the polishing machine. For the full symmetric type of abrasive, if you choose the wrong size, there is a risk of sticking. Triangular cone abrasives are most suitable for grinding special-shaped parts with complex structures due to its sharp corners and edges which can reach smaller gaps and holes. You can also choose to mix different shapes and sizes of plastic polishing media together.
