Laser Welder Nozzle Replacement

From source part to CAD quote

Using the original nozzle as a reference, I rebuilt its geometry in CAD and sent the model for a one-piece vendor quote in about two hours. This case study ends at the quote stage.

OEM replacement

Purchase one new OEM nozzle.

One-time OEM price$1,000

$550 lower quoted cost55% below the stated OEM price

This compares a CAD-and-vendor quote with the stated price for one new OEM nozzle. It does not represent a completed purchase, verified in-service savings, or equivalent performance.

Project stage

The vendor described the one-piece offer as vacuum cast and polycarbonate. The exact resin and process would need to be confirmed with the vendor before ordering. The part has not been presented here as manufactured, installed, or tested on the laser welder.
