Abstract:
1. A method of manufacturing a sucker, the method comprising: forming the sucker by an injection molding method; providing a baking device with temperature and moisture circulation control; heating the baking device to a temperature ranging from 60 to 90 degrees Celsius; moving the sucker from an injection mold into the baking device; heating the sucker in the baking device, that is heated to the temperature ranging from 60 to 90 degrees Celsius, for about 4 hours so as to purely temper the sucker in the baking device for rearranging chain molecules of the sucker; and cooling the sucker down to a room temperature such that an attaching surface of the sucker is substantially flat, wherein a gap between a hypothetical level line aligning to a center portion of the attaching surface and another hypothetical level line aligning to a rim of the attaching surface is 0.8-1.2 mm.
