plate plastic welding is generally used to weld large and irregular
shaped plastic parts with difficult contours and joint lines. Hot plate
welding uses a heated platen to radiate heat through close proximity
and melt the joining surfaces. After the part interfaces have been
melted, the parts are brought together to form a molecular, permanent,
and in many cases a hermetic seal. Hot plate welders are commonly
available to join parts in either a vertical or horizontal plane.
