The Dewaxing Autoclave is used for removing the wax patterns in the ceramic shell in the investment casting line. It is designed as an integration of steam boiler (outer chamber) and de-wax chamber (inner chamber) to save space and easy for maintenance. It is important that the inner chamber is always in the high temperature atmosphere, when the the high-temperature steam in outer chamber enters inner side, the pressure balance time is fast to reduce the moisture content in the drained wax, the time needed to process the recovered wax is short and the damage is less, thus to increase the wax recirculating efficiency and decrease the production cost. Because of the rapid pressure balance time, the out of the ceramic shell will be pressed in a short time to avoid cracking due to the wax heat expansion. Therefore, the ceramic shell can get a good performance by using this Dewaxing Autoclave. This machine has been used widely in many foundries worldwide.
