——A special product for high pressure castingprocesses in the ceramic industry, slip pressure: 8-30 bar
>>
The
porosity, pore distribution and the strength of the porous resin can be optimized
and adjusted depending on the requirements of various applications of the high
pressure casting process. According to the porosity the porous resin is divided into
different series, the following five types are commonly used in the ceramic industry: SA, MA, MC, ME and MF, this can satisfy the different demands for the high-pressure
casting applications.
>>
the porous resin material can satisfy the demands for highest casting quality. Low shrinkage of the
material ensures the high accuracy of each single part, as well the parts
with complex geometry. High strength, high abrasion resistance and the defined
porosity result a long service time of the resin moulds, achieve optimal
casting quantity .
>>
According to the optimization of the particle size distribution the
material has a excellent working ability for the moulding.
