Tube-In Molds

Get $5.00 off when you buy any three tube-in molds, use the code Tube-in Bundle !
The tube-in casting molds allow you to case objects on your tubes such as labels, stamps, metal foil, or anything else you can imagine. These molds use stoppers that go through the side of the mold to plug the tube. The stoppers are reusable for multiple casts and provide a good seal for the tube. These molds can be used under pressure without fear of leakage.

Most tube-in series are universal in nature, if the tube length is close and bushings are the same size or smaller, then the tube-in blank should cast properly. If you are looking to save money, the common molds such as sierra, junior or patriot can cast smaller tubes with the aid of adjustable spacers you can make for a few extra dollars with our replacement stoppers. Please visit IAP Kit Bushing and Tube Reference for various pen kit dimensions.

Our preferred types of labels for clear cast pen blanks can be purchased at OnlineLabels.com. We recommend Alumilite Clear or Clear Slow (urethane resin) for casting labels, which we now have available in 2#, 8#, and 16# sizes. 

  • OL9805WJ - Weatherproof Matte for Inkjet printers full size label 8.5" x 11" with a 1/2" border, so the actual print area ends up 7.5" x 10". We print using Microsoft Word - narrow margins and centering the page of labels. See our video for more details.

Blue molds except Gisi Style Molds cast Polyester Resin (Silmar 41), Urethane Resin (Alumilite Clear), and Epoxy Resin.

Mold release sprays help to extend the shelf life of our molds. We recommend Stoner Thermoset for Polyester and Epoxy Resins, and Stoner Urethane for Urethane Resin.
