Abstract
A material dispense tip includes an elongated hole in an elongated neck that extends from an input end of the neck to an output end of the neck. The hole at the output end of the neck has a first diameter. The output end of the neck is positioned against a die surface. A punch is inserted into the hole at the input end of the neck. An external force is applied to the neck to cause the output end of the neck to be deformed under compression by the die surface, to reduce the diameter of the hole at the output end of the neck from the first diameter to a second diameter that is less than the first diameter.
Claims8
A method of forming a dispense tip, comprising:
- forming a neck hole through a length of a body of material;
- forming an inlet hole at a distal end of the neck hole, the inlet hole having a first inner diameter;
- forming an outlet hole at a distal end of the inlet hole, the outlet hole having a second inner diameter less than the first inner diameter, a first inner taper transitioning the inlet hole from the first inner diameter to the second inner diameter;
- forming an outer taper having a width that decreases along a longitudinal axis of the length of the neck hole in a direction of a distalmost end of the outlet hole;
- and
- reducing the width of the outer taper at an output end of the body of material from a first outer width to a second outer width including reducing a width of an opening at the distalmost end of the outlet hole to a third inner diameter that is less than the second inner diameter.
