Quick Details
Specifications
Riser tube is a critical part of low pressure die casting machine.Molten aluminium is transported by pressure from holding furnace via riser tube into a mould every 3--5 minutes.Iron riser tube in traditional production could not guarantee continuous casting and high quality,so aluminium titanate becomes ideal material of riser tube due to its low thermal expansion coefficient,good thermal shock resistant and no wetting by molten metal.
Our aluminium titanate riser tube produced by german patent get long service life and its combination property can reach the international advanced level.
