Product overview

4mm Glass Beads is supplied by Glass Beads for production and maintenance blasting operations requiring process consistency, practical media recovery, and stable finish quality.

Industrial Use of 4mm Glass Beads

This grade is used for heavier surface preparation and oxidation removal. It is suitable for cabinet blasting and pressure blasting systems configured for reusable glass media cycles.

The achieved finish is typically coarser matte profile suited for pre-coating prep, depending on pressure, nozzle distance, and angle control during operation.

4mm Glass Beads Size and Selection Notes

Nominal size profile: ~4.0 mm. Teams should validate media choice against part geometry, contamination load, and required final surface condition.

Compared with 2mm and 3mm, 4mm is more aggressive. Compared with 6mm, it is generally better for jobs requiring less substrate stress.

Recommended Applications

4mm Glass Beads is used for cleaning, surface preparation before coating, restoration work, and controlled finishing on suitable metal substrates. Process settings should be tuned to minimize unnecessary base-metal stress while achieving target coverage.

Glass Beads supports practical grade selection for workshops, fabrication lines, and industrial maintenance teams requiring repeatable blasting quality.

Useful References

Process Control Guidance

Maintain dry compressed air, stable feed rate, and appropriate stand-off distance for uniform results. Screen recovered media periodically to manage fines and preserve finish consistency across repeated blasting cycles.

For sensitive components, begin with conservative pressure settings and increment gradually until the required cleaning and finish target is reached.
