Double walled foundry mould box - with spacer - reinforcing elements between inner and outer walls

摘要

In a double walled mould box the inner walls are attached to the outer walls not only along the edges but also over their surface for which support elements inserted between the walls are employed. Rolled profile section material is used for the connectors which render the box more rigid and prevent the inner wall from bulging into the space between the walls since they also act as spacers.
