According to its structure and dimension, the original stamping forming process of the lipstick casing pipe was analyzed. In view of such drawbacks as dispersed working procedures, lower efficiency and unstable product quality in the original manufacturing process, wall thickness of the lipstick casing pipe was modified and became thinner than its original size with the premise of ensuring utility performance. A new manufacturing process for the modified lipstick casing pipe was provided and a fully automatic stamping die, which is more secure in operation, lowers raw material expense and has higher production efficiency, was designed. |
