A method of manufacturing clips is described, The method comprises the steps of extruding a incited thermoplastic resin into thin extrudate and forming the extrudate into a plurality of clips. The forming step comprises one of (a) a step of vacuum thermoforming the extrudate into a plurality of clips by pulling the extrudate over a female mold and pulling a vacuum between the mold and the extrudate; or (b) the steps of providing a forming tool perpendicular to the extrudate, the extruding tool having a shape corresponding to the inside of a single clip; forming the single clip by contacting the extrudate with the forming tool and retracting the forming tool; advancing the extrudate; forming a second single clip by contacting the extrudate with the forming tool and retracting the forming tool; and cooling the formed clips. |
