Plastic Tumbling Media for Soft Metal Finishing

$2.50

Plastic tumbling media is used for softer metals such as brass or aluminum. It provides a very smooth surface finish but results in a matte appearance with a slight sheen.
Plastic media is 30% lighter than ceramic media, resulting in less damage to the workpiece. Plastic media does not discolor metals and effectively removes burrs. This type of media performs well in pre-plating treatments.

Applications

Plastic Tumbling Media Applications

Plastic tumbling media is widely used for mass finishing applications where controlled cutting, edge protection and surface refinement are required.

Aluminum Parts

Suitable for deburring, edge rounding and surface smoothing of CNC machined aluminum components and cast aluminum parts.

Brass & Copper Parts

Used to remove machining burrs and improve surface uniformity while reducing aggressive contact with relatively soft metal surfaces.

Zinc Die Castings

Plastic media can be used for deburring, deflashing and surface preparation of zinc die-cast components.

Plastic & 3D Printed Parts

Suitable for smoothing rough surfaces, removing light flash and improving the appearance of molded and 3D printed plastic components.

Precision Machined Components

Different plastic media geometries can be selected to reach corners, grooves and recessed features while maintaining controlled finishing action.

Pre-Plating & Pre-Coating Finishing

Plastic media can be used as part of surface preparation processes before plating, coating, painting or anodizing, depending on the required surface condition.

Plastic Media Cutting Grades

Plastic finishing media is available in different cutting grades to accommodate different surface conditions and finishing objectives.

Fast Cutting Plastic Media

Designed for applications where stronger cutting action and shorter processing cycles are required. Recommended for: Heavy burr removal Surface preparation Die-cast components Machined parts with visible machining marks Pre-coating and pre-anodizing preparation

Medium Cutting Plastic Media

A balanced option between cutting efficiency and surface refinement. Recommended for: General deburring Edge rounding Machining line removal Aluminum and brass components General-purpose vibratory finishing

Light Cutting Plastic Media

Designed for gentler surface refinement where appearance and surface quality are more important than aggressive material removal. Recommended for: Fine surface smoothing Delicate components Secondary finishing Cosmetic parts Final-stage surface refinement

How to Select the Cutting Grade

If you are unsure which grade is suitable, provide us with: Part material Part dimensions Current surface condition Burr size or machining marks Desired surface finish Finishing machine type Required cycle time

Our engineers can recommend a suitable media combination based on your application.

Frequently asked questions

Plastic tumbling media is an abrasive-filled polymer media used in vibratory finishing and other mass finishing processes. It is commonly used for deburring, edge rounding, deflashing and surface smoothing.

Plastic media is commonly used with aluminum, brass, copper, zinc die castings, plastic components and other parts where controlled finishing is required.

Yes. Plastic media is commonly selected for aluminum because its lower density and controlled cutting action can help reduce excessive surface damage during deburring and smoothing.

MOQ: 25kg per size/shape/grade combination
Recommended Order: 500kg+ for shipping efficiency
Lead Time: 15-20 days for 1-20 tons (standard 20mm media)
Larger Orders: Contact us for lead time on 20+ tons
Sample Orders: Starting at 25 kilograms, Available for testing before bulk order

Yes. Plastic tumbling media is commonly used in vibratory finishing machines. Media selection should be matched to the machine type, part material, part geometry and desired finish.

Media life depends on the cutting grade, machine, cycle time, compound, part material and finishing intensity. More aggressive cutting applications generally consume media faster.
