Make Your Own Plastic Worms
Soft plastic lures are produced from a liquid plastic
plastisol. This material is manufactured as a white liquid about the
consistency of water. When the plastisol is heated it turns clear
and thickens to a material about the consistency of syrup, which
upon cooling forms a soft plastic material. This is the basic
material for making soft plastic lures.
Liquid plastic, rubber molds,
hard plastic molds,
color for plastic, melting pan, and hot plate.
Softener and hardener if you want to change the consistency of
the plastic. Additional materials would include
lure glitter and
worm oil. The melting pan needs to have a small pouring spout
formed in it. This can be done with a pair of pliers.
Melting the Plastic
The plastic liquid is thin and white. It should be
mixed well before being used. Pour the plastic liquid into the
melting pan. Don't fill the pan too full as this will make it
difficult to pour. Heat the plastic carefully and stir frequently.
The plastic melts at about 350 F.
BE SURE AND HEAT THE PLASTIC LIQUID IN A WELL
VENTILATED AREA AS THE PLASTIC WILL PRODUCE FUMES AS IT MELTS.
OVER-HEATING WILL CAUSE EXCESSIVE FUMES AND WILL SCORCH THE
As the material heats it will thicken and turn
clear. Continue heating and stirring until the plastic is smooth and
about the consistency of syrup.
Add color to the desired shade. Most colors can be added to the hot
plastic, but fluorescent colors will be brighter if added before the
plastic liquid is heated. Stir well and you are ready to pour into
the mold. If you want to pour two color worms, melt two pans of
plastic, pour the first color then immediately pour the second
color. The 2 colors must be poured together while they are still
melted or they will not stick together.
Pour the plastic into the mold. Wipe the spout of the pouring pot
after pouring a worm to prevent the plastic from running down the
outside of the pot and scorching on the burner. A paper towel works
well for this.
Allow the worm to cool until it is firm, probably a minute or two,
then pull from the mold and place in a pan of cold water to finish
The firmness of the plastic may be adjusted by adding softener or
hardener. Softener may be added to the melted plastic, but hardener
should only be added to the plastic liquid before it is heated.
MELT AND POUR PLASTIC IN A WELL VENTILATED AREA. DO NOT GET THE
MELTED PLASTIC ON YOU AS IT IS VERY HOT AND WILL CAUSE BURNS.
