An important milestone in this area is the bulkhead system, which enables optimised use of the casting mould. The mould adapts to the respective product requirements in its effective lengths by means of adjustable bulkheads. This is particularly advantageous in markets that require a wide range of product sizes.The bulkhead is manually positioned in the mould and fixed without electricity to the lower part of the mould and one of the mould side parts using three switchable permanent magnets. With the help of a lever, it is possible to switch between two magnetic states in order to firmly connect or disconnect the bulkhead to the mould side part and the mould bottom part. Additional sealing lips prevent the AAC mix from escaping.After reaching the required cutting strength, the aerated concrete cake is transported to the cutting plant. The mould turning plant grabs the mould, tilts it by 90%u00b0, places it on the mould side plate not connected to the bulkhead, and automatically demoulds the cake. Similar to a mould with fully utilised volume, the mould with integrated bulkheads is also reassembled into a complete casting mould after the demoulding process and oiled. The bulkheads remain in the casting mould until the product requirements change.The option of individually adapting the effective length of the casting mould to the products significantly reduces the production of unwanted by-products and green waste. This considerably increases the efficiency of an AAC plant.Optimised use of the mould: the bulkhead is securely attached to the lower part and one side of the mould using three switchable permanent magnets.
