Tip seal for scroll type compressor and manufacturing method therefor |
摘要 |
One or two submarine gates 23 are located at portions of a mold corresponding to one or both ends of a tip seal to be molded. Synthetic resin is injected through the submarine gates 23. When the mold is opened after the synthetic resin is solidified, a molded product is cut off and separated by shearing from a runner 22 at a tip 23a of each of the submarine gates 23. Thus, no convex portion is formed as a gate trace on the end of the tip seal as a molded product when it is cut off. When the tip seal having no convex portion on the end thereof is inserted into the mounting groove of a scroll type compressor, the tip seal exhibits an excellent sealing property. With the aforesaid method, a tip seal excellent in a sealing property can be easily manufactured.
