A steel deep drawn cup with stem – the probe-shell form: a drawn cup whose closed end extends into a stem tube. One piece, seamless, so the tip the sensor sits behind has no joint between it and the stem.
Function and Design
Cup work is unforgiving: a few hundredths in the wrong place and the assembly will not go together. The cup tolerances that matter are confirmed with capability data before pricing is agreed.
What Makes It Work
- Family page: your print sets dimensions, features and tolerances.
- Deburring and cleaning happen before packing, so the parts go straight to assembly.
- Consistent batch quality – first article verified, production sampled against the same dimensions.
- Material: carbon steel (SPCC / DC01 or to print) for the cup, with material certs issued together with the dimensional report.
- Process: tube drawing, straightening and finish turning in one flow for the cup, stem length held to the print.
- Finish: The cup ships natural unless the print calls for plating or coating.
- Size: Dimensions of the cup follow the customer print; specials are quoted from the drawing.
- Custom: Send the cup drawing for a quotation with sample lead time and material options.
Where It Is Used
Production volumes of this part run in medical and food-grade devices, automotive sensor stems, instrument capillary lines.
Factory-Direct Advantage
A cup looks like the simplest item in a catalogue and is often the most demanding to make consistently. The cup is produced to print, with the features that carry function inspected first.
