Claims20
A method of securing a styrene ethylene butylene styrene copolymer (SEBS) tip to an extruded dart body, comprising:
- forming a tip assembly by inserting a tip insert into a die of an injection molding machine, wherein the tip insert has a central opening extending therethrough and a plurality of individual features extending from an exterior surface of the tip insert;
- insert molding a SEBS material wherein the die of the injection molding machine is configured to allow a portion of the SEBS material to extend into a portion of the central opening and cover some of the plurality of features extending from the exterior surface of the tip insert;
- removing the tip assembly from the injection molding machine;
- and
- securing a forward end of the extruded dart body to at least one of the plurality of individual features of the tip insert that is not covered by the SEBS material.
A method of securing a styrene ethylene butylene styrene copolymer (SEBS) tip to an extruded dart body, comprising:
- forming a tip assembly by:
- injection molding a tip insert, wherein the tip insert has a central opening and a plurality of individual features extending from an exterior surface of the tip insert;
- co-molding a SEBS material with the tip insert, wherein a portion of the SEBS material extends into a portion of the central opening and covers some of the plurality of individual features extending from the exterior surface of the tip insert;
- extruding a body of the dart;
- and
- coupling the body of the dart to the tip insert via a heat treating process.
