K2 Next

VPC K2 NEXT Aftermode without oxidation This machine like the predecessor VPC k2 utilizes the two methods of vacuuming of casting investment (Inside) from one side and Also pressurizing the melting process by injecting the melting material. The VPC K2 NEXT utilizes the technique called Aftermode. In fact this technique refers to the lower proportion subsequent exert of inert gas pressure after primary initial exert of pressure. De-Gassing The vacuuming suction system carries out two major rolls: One is the removing the oxygen from the casting investment (inside) the casting. Also the adhesive material of gypsum and epoxies of crucibles generate gas in contact with molten metal. This contained gas can be cause of porosities or not filled thorough its gas remaining in the cast tree- It blocks the pathways of the casting. On the other hand in a conceptual mistake increasing the pressure timing causes the increases of non-filled casting pieces. Capabilities Degassing removing these gasses along with the Aftermode makes possible the working of the fine details of the casting by injecting the metal into elaborate part spaces of the crucible mold. Existing Aftermode cannot avoid oxidation of metal and crucible in inserting flask. This shortcoming has been addressed in the PVC K2 NEXT. This way: No metal leakage is necessary especially for stone set flask. Yasui Aftermode provides minimum insert gas consumption to avoid oxidation with VPC KT18 since 2006. Yasui DeGassing system provides optimum DeGassing and its timing to minimise non field pieces in casting. Full set parameters in memory with comments. Whole set parameters (RCIPE) can be seen at a glance to make sure casting quality. 100 Memories which has comments provides easy management. Heat output control to minimize alloy evaporation -Variable Heat- Zink in alloy near crucible starts to be melted just after start heating and zinc can be evaporated before mother metal starts to be melted. This can lead to increase of purity which means loss. K2 NEXT solves this problem with variable heat. Extra Mixing Heat output becomes weaker after metal is melted. Therefore mixing power can be weaker. K2 NEXT provides Extra mixing switch for stronger mixing. This parameter (ON) or (Off) is included in " RECIPE".
