High-capacity 8-slot HDPE casting mold designed specifically for DogBone label casting plugs. Cast two tubes per slot for Jr. Gent, Sierra Clone, Bolt Action, and most other common pen kits.

Product Description (copy/paste ready):

If you love label casting with dogbone plugs and want serious production capacity, this 8-slot tube-in casting mold is the perfect upgrade. Designed to accommodate our dogbone label casting plugs, it lets you cast two tubes per slot for most popular pen kits (Jr. Gent, Sierra Clone, Bolt Action, and more).

Each slot measures 7" long, giving you plenty of room for full-length blanks with excellent results. The mold is precision-milled from durable, virtually indestructible HDPE — no warping or cracking like flexible silicone molds.

Key Features:

8 slots — cast up to 16 tubes (2 per slot) in a single pour
7" slot length — ideal for standard pen blanks
Compatible with DogBone label casting plugs
Works with all common tube sizes (Jr. Gent, Sierra Clone, Bolt Action, etc.)
Designed for pressure casting in 5-gallon or larger resin pressure pots (will NOT fit in 2.5-gallon pots)
Robust construction built for repeated use

This mold is strictly intended for tube-in / label casting. All standard casting resins perform great, including JB Royal Epoxy, Alumilite urethane, other epoxy resins, and polyester resins.

Important Notes:

A good release agent is required. We highly recommend applying it thoroughly to the chambers and any plugs/inserts before pouring.
For easiest demolding, use a rubberized dead blow hammer after full cure. Tap the bottom and sides, then flip and tap the ends on your workbench.
Alumilite and polyester blanks typically release very easily. Epoxy blanks may need a few extra taps or a blast of compressed air.

Usage Tips:

Always pressure cast when possible for bubble-free results.
Test your setup in your pressure pot before full production runs.
Clean the mold thoroughly after each use for maximum lifespan.

This heavy-duty mold is perfect for serious hobbyists and volume casters who want reliable, repeatable results with DogBone label casting.

Transform your blanks into showstoppers with these pro-level insights. Our upgraded V2 blanks boast finer shredded plastic for ultra-smooth turning and minimal chip-out— a game-changer over V1. Dial in sharp carbide or HSS tools, crank speeds to 2,000–3,000 RPM, and take feather-light cuts (0.005–0.015 inches) to dodge melting or gummy buildup. Wet-sand from 220 to 2,000 grit, zap pin-holes with thin CA glue, and crown it with Magic Juice polish for that mirror-finish glow. Dive deeper with our guides:
