With a temperature rating of 200[degrees]C, the splice combines a nickel-plated copper crimp barrel with a separate, heat-shrinkable, transparent sealing sleeve
that provides strain relief and environmental protection.
The ejector system consists of drill head, outer tube, inner tube, connector, collet and sealing sleeve
. The drill head is screwed to the drill tube by means of a four-start square thread.
A melt seal is achieved directly at the gate by placing sealing sleeves
around the tips: the nozzle body itself is not surrounded by melt.
By placing special sealing sleeves
around the tips, a melt seal is realised directly at the gate.
The first industrial application of memory alloys occurred in 1969, when they were used in the coupling and sealing sleeves
of hydraulic pipes made by Raychem Corp.
