? Maintenance is carried out by an in house technician who calls on the manufacture to send a representative to give training where it is required
? Tooling is purchased as locally as possible to facilitate rapid modification of the mould if required (the tooling company is actually across the road) for development of new moulds these are logistical considerations as the moulds can weigh up to 1500 kg and as such are very expensive to move around although tooling can be purchased abroad cheaper the lead times and transport costs would negate any saving
? Service requirements: water & electricity from the national grid system although at the current time their electrical requirements are greater than the supply available restricting their capacity but this problem is being addressed
