Injection molding method utilizing primary and secondary resin flow paths |
摘要 |
A method and system for injection molding a hollow plastic article utilizing a secondary resin flow path which communicates one portion of an article-defining cavity with a second portion of the article-defining cavity. The second portion of the article-defining cavity is typically the hardest-to-fill area of the article-defining cavity.
