Among all the mechatronic products, except some special slip rings that need over a thousand pieces of components, most slip rings are relatively simple in structure. The major components are shaft, carbon brush and lead wires. There are many processing methods of producing these components like injection molding, metal stamping, pressure casting and machining, etc. JINPAT Electronics uses injection molded part most. JINPAT capsule through bore slip ring that has the largest annual production quantity and sales volume adopts injection molded components.

As for metal stamped parts, they are basically applied as slip ring housing. Some of JINPAT standard miniature slip rings and super miniature slip rings take up stainless steel stamped part as housing. The stainless steel stamped housing show excellent impact endurance. The pressure casted components are very similar. Most of the slip rings for construction machinery takes up pressure casted housing to cope with the harsh working environment.

JINPAT High Frequency Rotary Joint

Pneumatic/Hydraulic rotary joints, fibers optic rotary joints, high frequency rotary joints and some custom slip rings take up machined components as their stators and rotors. For standard JINPAT pneumatic hydraulic slip rings, most of them are aluminum alloy, while custom solutions take up steel. So generally speaking, custom pneumatic hydraulic slip rings are much bigger than the standard models, meanwhile they can cope with higher gas/liquid pressure.

Last but not least, let’s have a look at the fiber optic rotary joints and high frequency slip rings. Both the standard slip ring and the custom one adopt stainless steel as material. But given the different transmitted medium, these two kinds of slip rings vary in their inner structures. The rotating speed of a high frequency slip ring is usually below 100rpm while that of a high frequency slip ring can reach up to 20,000. So there are quite different demands in the machining techniques for the components. And obviously, since the high frequency slip ring has a higher rotating speeds, it demands a more precise and refined machined parts to allows a faster while endurable rotation.
