Factories

Allied Glass operates two manufacturing sites, one in Leeds and another in Knottingley.  Together, these two factories have the ability to produce 13 million units every week. Two flint furnaces are installed at Leeds, with a combined maximum capacity of 550 tonnes/day, feeding nine production lines.  Another seven lines are installed at Knottingley, served by 2 flint furnaces, one of which produces premium quality flint glass, the other benefits from a feeder colour system.

A mixture of 6 and 8 section IS machines are operated at both sites, including an increasing number of 51/2in and 6¼in CD models to achieve enhanced flexibility, especially when making specially shaped bottles. 

The bulk of production is achieved using the blow-blow process, together with a small amount of press-blow manufacture, which is used to produce wide mouth ware at the company's Knottingley facility.
