Spline connector is the part with ridges or teeth for transferring torque, Spline Sleeve Parts are the spline connectors with internal spline.   


Auwell spline sleeve parts are made by alloy steel which normally is extruded seamless tube, some of them made by forging followed by machining. The through-hole of spline sleeve parts production uses pull / push broach or extrusion-type method. The special coatings or plating may be applied to metal fasteners to improve their performance characteristics by, for example, enhancing corrosion resistance. Common coatings/platings include zinc, chrome, and hot dip galvanizing.

Auwell is capable in designing the necessary fixtures and tools for the milling process and test gauge for spline sleeve parts mass production quality control. CMM is available for sample dimensional inspection. PPAP documents are available upon request.
