The lost wax casting industry in China has accumulated more and more solid strength ready, now in the casting industry of the future will be more forward, so we in if development promotion in the technical level will be more conducive to our foundry industry towards the international, towards the world.So want to improve the level of technology from the following several points to do!1, the development of simulation of lost wax casting technology:Improve the accuracy of prediction, to strengthen the process control and improve the yield.At present, the problem of regularity to master also is not very well, thus affecting yield in mass production.
