The original mold and molding material of the essential oil bottle are very poor, the density is not enough, and the oxidation after high temperature is too fast, forming a fine pit surface of the mold, resulting in the surface of the essential oil bottle after molding is not smooth.
Machine feeding speed is not uniform, improper air nozzle adjustment will make the flavor oil bottle initial mold and mold temperature is not coordinated, easy to produce a cold point in the flavor oil bottle, directly affect the smoothness of the flavor oil bottle.
If the machine is too fast or too slow, the oil bottle will be uneven, the bottle wall will be thin and thick, causing spots.
