摘要

The present invention relates to a muffler manufacturing method for a car air conditioning system and a muffler thereof. The present invention is configured to comprise a fixing step (S1) of fixing the outer peripheral one side of an object to be processed (100) with a fixed die (110); a pressurization step (S2) of inserting a movable die (140) from both ends of the object to be processed (100) into the inside thereof and contracting the object to be processed (100); a stretching step (S3) of pressurizing the inner surface of the object to be processed (100) and forming an inlet portion (44) and a discharge portion (46) integrally at both ends of a muffler body; and a cutting step (S4) of cutting the object to be fitted into a size in any one area of a refrigerant pipe (4).
