How easy open lids are produced
1. Cutting Cutting refers to the cutting of tin-plated sheet steel strips used for punching caps.2. Flushing and round caps Before flushing, the tin-plated sheet must be coated with a very thin layer of edible liquid wax oil to avoid mechanical damage during the capping process and to ensure the continuity of the coating film and tin coating. Rectangular and corrugated tin-plated steel strips are cut by a punch, and a can lid with a certain specification and standard expansion ring pattern, countersunk degree and edge shape is produced under the action of the punching die. Then round the edge through the round edge mechanism to form a complete cover edge.
3. Glue injection and drying To ensure that the empty can has a good sealing performance, in addition to pressing the double crimping, the sealing effect of the sealant in the double crimping seam must also be used.
4. The manufacture of easy-open lid The easy-open lid is made of metal (aluminum, tin-plated or chrome-plated thin steel plate), has notches in the opening part, and is equipped with lifting parts to facilitate the opening of the can lid. The easy-open lid has a hole-open easy-open lid and a full-open easy-open lid.
