Virtual tour of our forging process

Machining process

Rust prevention

  • Protective coating is applied on the machined components to avoid corrosion during transportation and storage.
  • Tower flanges 100% area including holes are coated by spray painting with Weldable Epoxy Zinc primer. This is readily weldable and doesn’t have any detrimental effect on welding quality hence there is no need to remove before welding.
  • Tower flanges normally bearing rings are coated with Mineral based oils. After coating, rings are wrapped with VCI films to ensure longer shelf life.

Export worthy packaging

  • Tower flanges: Tower flanges are stacked keeping wooden spacers in between to avoid metal-to-metal contact. Metallic studs with rubber tubes on top are passed though the holes and clamped to prevent relative movement between flanges
  • Bearing rings: After applying anti-corrosive oil, bearing rings are wrapped with VCI films followed by stretch film. Edge protectors safeguard the bearing edges/corners from damage. Rings are stacked and clamped with wooden runners
