Resin Casting Tutorial
Lets make these.
It has a 7 minute pot life and a 30 minute demold time.
I recommend getting some squeeze bottles like restaurants use for condiments to make it easier to pour.
I use Alumilite's Black dye to get a gray resin. 305 is usually bright white. A few drops in the A side jug and shake till blended. Go slow with this and test until you get a shade you are happy with.
Tools and work area
- Syringe for injecting resin into the mold, or pulling resin through a vent gate.
- Graduated mixing cups, labeled in CC
- Mixing Stix
- Rubber bands to keep molds together
- Clamp(s) for molds
- Hard board or plastic card used when clamping the molds.
Using a hardboard or thicker plastic card line up the halves and hold them together. Use rubber bands or clamps. You have to figure out the right amount of pressure for your mold. Too little and the resin will seep out of the bottom, too much and you will warp and deform the cast.
Mixing and pouring tips
- Shake both sides of the product to ensure they are fully mixed, especially is you are using a resin dye.
- Stir the A&B sides well, make sure it is completely mixed.
- With this mold I was able to pour directly into the main gate, I used the syringe slowly pull resin & air pockets up through the vent channel.
- Rotate and shake the mold to help free any trapped air pockets.
- Wear gloves you don't want mixed resin on your hands.
First Cast from these molds
The vents on this mold did work right the first time.
With a little work these legs will be usable, a small amount of green stuff and less time than I have spent on most ForgeWorld I have g
