The Remelt Process - Omega Windows & Doors

Proudly owned by McKechnie® Aluminium

Remelt Casthouse

This is where it all starts - casting aluminium logs for the extrusion process.

McKechnie® operate New Zealand's only remelt casthouse which offers OMEGA® Windows & Doors a unique advantage.

We have total control of the casting process, which is important for ensuring consistency in the quality of aluminium logs we produce for extrusion. 

By using recycled aluminium scrap from our own manufacturing process and scrap sourced from other New Zealand extruders, we are doing our bit to protect the environment.

The energy consumed to make extrusion from recycled aluminium is 10 times less than the energy required to make an equivalent amount of extrusion from virgin aluminium sourced from the aluminium smelters.
