Though the analyzing of the upper part of oil box and the designing of the structure of the die, the article discusses the characters and advantage of the lowmeltingpointalloy die.
The results indicate that the classical heat transfer mechanism is suitable for the medium wall load and the potential heat of the low-melting-pointalloy is useful for high wall load.
To solve the problem of short service life and poor performance of lowmeltingpointalloy mould manufactured by arc spray forming, the manufacturing of stainless steel mould has been presented.
