PRODUCTION

From raw iron to finished drum

Six steps under one roof. Each step ends at a quality gate: if a casting doesn't meet spec, it doesn't move forward.

Molding at the TBP foundry
01
Molding

Sand molds are formed on automated molding lines with tight dimensional tolerances. Each mold is inspected before the pour.

Shot Blasting

Raw castings are cleaned and surface-prepared through high-velocity shot blasting, removing sand and scale for a uniform finish.

EQUIPMENT · AUTOMATED SHOT BLAST MACHINES✓ GATE 3 · SURFACE FINISH + RESIDUAL SAND
CNC Machining at the TBP foundry
04
CNC Machining

Every drum is turned on CNC lathes to OEM-spec tolerances. Pilot diameter, register, and braking surface are machined in a single setup.

Balancing at the TBP foundry
05
Balancing

Drums are dynamically balanced by machine, with corrections milled from the casting rather than added as welded weights. Run-out is checked against spec.
