摘要： A device 1 is provided for forming a plastics weld, to repair a crack in a plastic article or join two plastics parts. The device 1 comprises a barrel 2 having an internal chamber 3. A nozzle 19 may be part of the barrel 2 and forms a restrictive orifice outlet 4. A plastics filler rod 7 can be forced by drive rolls 6a, 6b into the chamber 3 through an inlet 5. A heater coil 8 is provided to heat the barrel 2. In use, the drive rolls 6a, 6b are actuated to fill the chamber 3 with filler plastics and generate a high pressure (eg 2500 psi or 17.25 MN/m²). Concurrently, the heater coil 8 heats the plastics in the chamber 3 to a molten state. The molten plastics is forcefully ejected through the orifice outlet 4. To effect the weld, the hot tip 4 of the nozzle is buried in the workpiece and drawn along the crack; it plasticizes the weld area plastics as it moves along. At the same time, the molten filler plastic is jetted into the molten weld area plastic and forcefully intermixed therewith to generate a competent weld.
