About this part
What it is and why it is made that way
Brackets are the highest-volume part in almost every assembly we supply. This line covers the pressed-steel support arms and mounting brackets used to fix motors, gearboxes, sensors and sub-frames to a chassis. Each bracket is run on a dedicated progressive tool so the hole pattern stays identical from the first piece to the last.
- Progressive tooling with a stable hole pattern across the batch
- Tapped, countersunk or plain holes to drawing
- Deburred and dressed on both faces
- Optional zinc plating or powder coating
Materials
- SPCC / SECC cold-rolled steel
- Stainless 304 / 201 sheet
- Galvanised steel
- Aluminium 5052 / 6061 sheet
Production processes
- Progressive stamping
- Single-bleed stamping
- Laser cutting
- CNC bending
- Welding and assembly
Typical applications
- Motor and gearbox mounting
