Packing drum lid and manufacturing method

摘要

The present invention relates to a drum barrel lid and a method for manufacturing the same, in the shear cutting step (S ₁ ) wave packing groove forming step (S ₂ ), packing material mixing step (S ₃ ), raw material injection step (S ₄ ) and the packing groove The heat hardening process (S ₅ ), which hardens the drum lid in which the packing raw material is injected at a temperature of 200 to 250 ° C., eliminates the cumbersome work of attaching the packing to the packing groove by gymning the drum lid, thereby greatly reducing the number of workers. The work time is shortened, the work efficiency is high, there is no fear of injury to the operator's hands, and the use of adhesive material is unnecessary, so that the worker's health damage caused by the hallucination of the adhesive is not caused even during long manufacturing work. Rather, the drum lid manufactured by the present invention has better packing characteristics and lower cost packing than conventional drum lids, in which the packing is bonded to the packing with an adhesive. Lid and a method of manufacturing the same.
