VACUUM CHAMBER FOR HEAT-SHRINKABLE TUBE

摘要

PURPOSE: A vacuum chamber for a heat-shrinkable tube is provided to uniformly keep the vacuum of the vacuum chamber by connecting the vacuum chamber to an auxiliary tank. CONSTITUTION: An adapter(120) is coupled to one side of a vacuum chamber(100), and guides a heated tube(200). An expansion tube(130) is inserted into the vacuum chamber, and has a plurality of holes(131). A vacuum pump(140) is connected to the vacuum chamber. The vacuum chamber expands the surface of the tube inserted into the expansion tube. An auxiliary tank(150) is connected to the vacuum chamber by a pipe(151), and uniformly keeps the vacuum of the vacuum chamber.
