Brush Trimming & Flagging Machine
One machine, two critical finishing processes — precision bristle length trimming and mechanical end-rounding (flagging) for a consistent, professional brush finish. Used for toothbrushes, hair brushes, and personal care brushes.
What This Machine Does
Trimming
Rotary blade cutting station that trims bristles to uniform length across the entire brush head. Programmable cut height with ±0.05mm repeatability. Ensures every brush face is flat and even.
| Spec | Value |
|---|---|
| Cutting Method | Rotary blade |
| Height Repeatability | ±0.05 mm |
| Max Brush Width | 120 mm |
| Cycle Time | ~3 seconds |
Flagging (End-Rounding)
Mechanical end-rounding process that rounds and splits bristle tips for soft-feel finishing. Critical for toothbrush and personal care brush quality — achieves >95% tip acceptance rate.
| Spec | Value |
|---|---|
| Process | Mechanical end-rounding |
| Tip Acceptance | >95% rounded |
| Compatible Bristle | PBT, Nylon 6.12, PA |
| Cycle Time | ~5 seconds |
Why One Machine Does Both
Trimming and flagging are sequential finishing operations that share the same workpiece positioning and handling. Combining them into one integrated station reduces footprint, eliminates inter-machine transfer, and ensures consistent quality. This is the standard configuration across the brush manufacturing industry.
Applications
Toothbrushes
Flagging is critical — end-rounded bristles prevent gum irritation. >95% tip acceptance rate standard.
Hair Brushes
Variable-height trimming for contoured brush pads. Consistent finish across the entire bristle field.
Cosmetic Brushes
Soft-tip finishing for makeup and personal care brushes. Gentle handling for premium natural filaments.
