Stopper Pipe
Because SG-28 silicon nitride ceramic has high density, high strength and high thermal shock resistance , it is the best choice for stopper tube in low pressure die casting.
Compared with aluminum titanate and alumina ceramics, silicon nitride has more excellent wear resistance and can ensure airtight of the stopper tube for a long time;
The high temperature strength of silicon nitride ceramic is very good, so it ensures that the stopper tube can still work for a long time under frequent operating conditions.
In view of the fragile property of silicon nitride ceramics, it is necessary to avoid large mechanical shocks, therefore, it must be careful and paid attention on the design and installation of the lifting transmission device.
