2、Before the exhaust must be exhaust treatment, that is, the two steam valves and drain valve all open, through the steam and raw materials and mold cavity in the air and water discharge, this step can be adjusted according to the mold temperature, generally 1 ~ 2S;
3,、The requirements of the steam, must be dry, can not bring water or pot of water
(1) Penetration time will be long (equivalent to high temperature boiled mold);
