Fabrication

Custom fabricated industrial components.

Fabrication is commonly used for large or complex industrial components manufactured from plates, sections, pipes or other engineering materials. Where required, fabricated components can proceed to machining or other finishing operations to achieve final dimensional requirements.

How it works

Custom industrial component manufacturing process.

01

Drawing & requirement review

Component drawings, specifications, materials, quantities, tolerances and inspection requirements are reviewed.

02

Manufacturing route planning

The appropriate combination of fabrication, rolling, machining, drilling and finishing operations is determined.

03

Material & production preparation

Material and production requirements are established according to the approved technical information.

04

Fabrication & machining

The component is manufactured through the required fabrication and machining operations.

05

Dimensional inspection

Critical dimensions and applicable drawing requirements are checked during and after manufacturing.

06

Final component readiness

The finished component is prepared according to the agreed project and delivery requirements.

Quality and dimensional control.

Custom industrial components often interface with other equipment and assemblies, making dimensional consistency important. Inspection requirements are established according to the component drawing and customer's technical specifications.

Who this is for

Who uses custom industrial component manufacturing?

Custom manufacturing is particularly useful when standard components are unsuitable or when a component must match an existing equipment design.

OEMs
Equipment manufacturers
Engineering companies
EPC contractors
Fabrication companies
Industrial component buyers
Maintenance teams
Replacement component buyers
Process equipment manufacturers
Replacement components

Custom replacement industrial components.

Replacement requirements may arise when an existing industrial component is damaged, worn, obsolete or no longer readily available. The replacement manufacturing approach depends on the available technical information and component complexity.

Integration with industrial equipment

Integrated fabrication and machining.

Some industrial components require multiple manufacturing processes before they reach their final form. Rajog can support manufacturing routes where fabricated, rolled or welded components require subsequent machining, drilling, facing, boring or other finishing operations — useful for large and engineered components where fabrication and final machining both influence the finished dimensions.
