1 Advantages & Key Features Super Fast Dry Dry Lost Wax Shell in Short Time. 1) small size tree 5 10kg( 22.05lb) 15 minutes or more 2) middle size tree 10 15kg( 33.07lb) 30 minutes or more 3) big size tree 15 60kg(132.28lb) 45 minutes or more 4) tree with cylindrical shape or holes 30 minutes Possible to Coat 6 Layers / Day. Applications Example 1 - Suitable for Large Item Small Volume Production - The Shell Surface 1)During Drying is Approximately ±15 (2.68F) in Case the Target is 25. 2)Wax temperature kept low - approximately 25 ( 77F). 3) Control with No Shell Cracks. 4)Combination use of microwave and cold air facilitates. Reduction of the Floor Space in Drying Room. Reduction of the Development Period of the New Products. Possible to Reproduce in Short Period when a Trouble Occurs. Reduction of the interest rate burden by half-finished goods being delayed. Significant Shell Defects Reduction. No Shell Cracks. Numeric Dryness Measurement with Shell Weight Change. ( PATPEND) Both Normal and Special Slurry Applicable. Flexible Application. Microwave Drying System for Large-sized Molds Microwave Drying Chamber BH BH 6-8 Sand Tank B Dry Shells in Short Time - Only 30minutes per layer Whereas with conventional methods of shell drying it takes approximately 2-3 hours for the 1 st and 2 nd layer, 3-4 hours for 3 rd - 5 th layers, and 4-8 hours for the following layers, Japan High Comm Microwave Chamber dries shells only in 30 minutes per layer. Sand Tank A Robot Tree Hanger Conveyor Slurry Tank A Molds with Hole Blower Slurry Tank B > Unload mold tree from conveyor with robot. > Dip mold tree into slurry and coat sand. Total System Control Panel Robot Control Panel > Put mold tree into multiple microwave drying Chambers by turns. > Take out mold tree from microwave drying Chamber.

Humidity reduced from 60% to 55% in 7 minutes. Humidity (%) Mold Weight 7 minutes : Microwave Drying C: Cooling After slurry dipping and sanding with robot, put mold trees into continuous type microwave drying system to dry molds. Unload the mold trees from the microwave drying system and load them to hanger conveyor. Repeat the same process to dry the following coats. Start of Drying During Drying Process After seal coating is dried, load the mold trees to hanger conveyor to send them to dewax process.
