Mold performance
This is a product with a shape resembling a cobra's head, featuring rubber-like injection molded parts and small pipe injection molded parts inserted on the sides. Both insert components have a slide structure that includes a core, which also serves to prevent punctures. Additionally, the bellows shape is designed for a release slide specification. The small opening has a slight undercut relative to the mold split, but since the material is soft, it can be released without difficulty. In this case, if the customer agrees, we can propose a solution that does not use a slide structure to reduce mold costs.
