Germany-based standard parts manufacturer Strack Norma says it has developed the deflection element Z7741 to provide the secure connection of cooling holes in an injection or die casting mould over multiple parts or mould plates. Z7741 bridges a cooling hole distance of 30 to 500 mm variably. The element, according to the company, is versatile and resistant to aggressive cooling medium as well.

Z7741 is available with a channel diameter of eight millimetres and comes in three lengths. As such, the deflection element offers a variable, bridgeable cooling bore distance from 30 to 500 millimetres to enable flexible installation as the length is individually adapted to the distance of the two cooling holes.

Depending on the mounting, the deflection element can be placed on the outer surface of the mould plates or inserted into the mould plates. Pull-out threads are mounted in the holders to enable easy dismounting. The deflection element is made of stainless steel and the seals consist of robust and temperature-resistant Viton (fluorinated rubber FKM). As such, they can also be used without corroding when aggressive cooling medium such as light acids is present.

This deflection element expands the company's existing system, deflection element Z7740. Z7740 has inserted heating- cooling channels that can be compactly deflected within a mould plate. This is done by means of an incorporated pocket, in which the element is sunk and screwed in with a flushed finish. Here too, internal threads in the holders allow easy dismounting. Z7740 is available in aluminium and stainless steel and has sealing rings, which are made of Viton as well.
