Comparing with cast iron materials, STA silicon nitride riser tube for low pressure die casting has low heat conduction,its super heat preservation can prevent the temperature reducing of aluminum solution in low pressure casting.
Comparing with cast iron materials, STA silicon nitride riser tube for low pressure die casting has low heat conduction,its super heat preservation can prevent the temperature reducing of aluminum solution in low pressure casting.We use the way of GPS to get high density,which makes it possible to keep high mechanical strength when temperature rises. It will reduce the risk of air leakage and damage if load and strength are weak It is not easy to adhere aluminum, so it makes daily maintenance more convenient.
Features
1. small thermal expansion coefficient;
2. Good thermal conductivity and good thermal shock resistance;
3. good thermal shock resistance
Applications
For low-pressure die casting machines.
