Mold repair: remove the remaining flash or parting line on the wax mold, carefully and gently cut off the flash or parting line along the wax mold with the cutting edge of the blade, and cut the flash formed on both sides horizontally. Vertically cut again, do not bevel, do not damage the wax mold, the small flash can also be wiped directly with a soft cloth. Repair of wax mold recesses: There are large and narrow recesses on the wax mold, which should be repaired with repair wax, and the shape should be correct after repair. Bubble repair: All bubbles on the wax mold must be broken, repaired with repair wax, and the shape must be correct after repair.
