Grandad's photos

Yesterday I bussed a group of 30 who all work in window framing companies, to look at NALCO's extrusion plant in Hamilton. As well as getting lunch, we all looked around the factory and viewed the aluminium being pressed from a 'log' into long lengths of window frame shapes. The machine heats the raw material to 400 degrees then forces it with 1500 tons pressure through the dies. We also looked at their powder coating and packaging. Very interesting!
