Here is the general ceramic media parameter information we can provide. There are different shapes: ball, cylinder, angle cut cylinder, triangle, angle cut triangle, tri-star, grain etc.The different sizes can increase or decrease its polishing ability. Besides, we can produce and supply polishing media of special and specifications designed according to your demands. We will try our best to help you solve your polishing problems.
How do I select between alumina and zirconia ceramic media for my application?
Alumina is the ideal choice for cost-effective general grinding, deburring, and polishing of metals/plastics. It offers high hardness at a lower price point, making it suitable for high-volume, standard finishing tasks. Zirconia is better for heavy-duty applications (e.g., grinding cast iron, titanium) or brittle materials (e.g., ceramic, glass) where media toughness is critical—it resists chipping and impact damage, extending service life. We recommend requesting free samples to test both variants with your specific workpiece and equipment.
What size media is best for my process?
The optimal size depends on your workpiece dimensions and finishing goal:
Micro-finishing (e.g., electronics components): 0.1-1mm spherical media.
General deburring/polishing (e.g., small hardware): 1-5mm cylindrical/spherical media.
Heavy-duty grinding (e.g., automotive castings): 5-20mm triangular/cylindrical media. Our team can calculate the exact size using your workpiece’s smallest feature (e.g., hole diameter, edge radius) to ensure media reaches all surfaces without getting stuck.
Can the media be reused, and how do I maintain it?
Yes—ceramic media is designed for multiple reuse cycles. To maximize lifespan:
Sieve media after each use to remove broken particles (use a mesh screen matching your media size).
Monitor particle size monthly—replace when media shrinks by 20% or performance declines (e.g., longer processing times).
Use compatible process fluids: avoid hydrofluoric acid with alumina media, and clean fluids regularly to prevent contamination buildup.
Is the media compatible with my existing finishing equipment?
Our Ceramic Media works with all standard B2B equipment: vibratory tumblers, rotary tumblers, ball mills, and centrifugal finishers. It’s denser than plastic/glass media, so you may need to adjust load capacity (we recommend 60-70% of drum volume) for optimal performance. Share your equipment model with our team, and we’ll provide customized loading and speed recommendations.
What is the lead time for custom orders, and can I request a small batch first?
Custom orders typically take 7-14 business days for production, plus shipping. We offer small-batch custom runs (as low as 25kg) for pilot testing—this lets you validate performance before committing to large orders. For urgent needs, we can expedite production to 5-7 days for a small premium.
Does the media meet industry-specific standards for my sector (e.g., aerospace, medical)?
Yes. Our media complies with AS9100 (aerospace), ISO 13485 (medical), and RoHS/REACH (electronics) standards. For medical applications, we offer FDA-approved variants with biocompatibility testing reports. For aerospace, we provide traceability documentation for every batch, including raw material certificates and performance test results.
