A brush factory that reads drawings.
InduBrush has been winding, tufting and knotting industrial brushes in Changzhou since 2004. We are a manufacturer, not a trading company — the people who quote your brush are the people who can walk onto the floor and change the machine setting.
Most brush problems are specification problems.
A brush that fails early is rarely a bad brush. It is usually the wrong filament diameter for the load, or a core that runs 0.4 mm eccentric and shakes itself apart.
So we spend the first conversation on process rather than price: what the line does, how fast it runs, whether there is coolant, what the failure looked like last time. Roughly a third of the orders we ship are for a brush the customer did not originally ask for — because the drawing pointed somewhere else.
We keep 1,800 custom toolings on file, from a 1980s tooling pattern for a German gearbox line to solar handling rollers specified last quarter. Repeat orders can be re-run from that file without a new setup charge.

Twenty-one years of
one trade.
We have deliberately stayed in one product category. Everything below is brush work.
Workshop opens with six staff
Two winding machines and a knotting bench, supplying local textile mills in Changzhou.
First export order
Strip brushes for an Italian door-seal OEM — the account is still active today.
Moved to the current 8,000 m² plant
CNC tufting introduced; wafer winding brought in-house instead of subcontracted.
ISO 9001:2015 certified
Dimensional reporting per lot becomes standard rather than optional.
Abrasive filament line added
SiC and Al₂O₃ nylon in-house, cutting lead time on deburring brushes from 5 weeks to 2.
What is actually on the floor.
Six processes cover every family we sell. Nothing critical is subcontracted.
Wafer winding
6 stations, Ø 50–400 mm. Filament tension logged per pack; diameter checked every 25 discs.
CNC tufting
4 heads, drill-and-fill, tuft pitch from 8 mm. Handles compound angles on roller bodies.
Strip forming & punching
Channel roll-forming to 20×20 mm, CNC punch for hole patterns, bend radius from 40 mm.
Wire knotting
Manual and semi-auto knotting for wheels, cups and conical brushes. Knot density to spec.
Trim & grind
CNC trimming to ±0.5 mm on face width; end facing for square-running rollers.
Inspection
CMM, TIR gauge and dynamic balancing to G6.3. Report issued per production lot.
Every lot ships with numbers, not assurances.
A dimensional report travels with each production lot: outside diameter, face width, TIR, filament diameter measured against the incoming certificate, and balancing grade where applicable. If a value is out of tolerance, the lot does not ship — we tell you before you find out on the line.
Filament is bought against certificate of analysis, and we retain a sample from each reel for twelve months so a field failure can be traced back to the batch.
