发明名称 METHOD FOR MOLDING A DECORATIVE ZIPPER PULL AND MOLD FOR A ZIPPER PULL
摘要 A molding process for creating a decorative pull has two separate molding steps. In the first molding step, a first top mold portion, and a bottom mold portion are used. The bottom mold portion has a mold compartment with an indentation in the bottom. An end of a soft string is placed in this compartment with the end disposed over the indentation. The first top mold portion is closed over the bottom mold portion and molding material is injected. The molding material enters the mold cavity and flows into the indentation to cover the ends of the string entirely, to create a first molded component. A second top mold portion is then placed over the bottom mold potion and molding material is then injected into the second mold cavity formed by the second top mold portion to cover the first molded component and create a molded pull for use on zippers or other items.
