Quick take

An aluminum injector with heating capability for molding soft plastic lures and DIY fishing bait creation.

This 120 ml (4 fl oz) aluminum injector is made for pouring hot plastisol into soft plastic lure molds at home. It has a 5/8 inch nozzle that fits most aluminum and stone molds, a locking nozzle, and rubber O-rings on the nozzle and piston to keep the plastisol from leaking. The plastic handle helps with grip, and the size suits baits under about 6 to 7 inches. Wear gloves while pouring, since the barrel gets hot.

Best for

Experienced anglers who tie or make their own soft plastic lures
Crafting custom paddle-tail swimbaits and creature baits
Making small to mid-size lures in engineered or aluminum molds

Skip if

You want ready-made lures; this is for DIY fabrication
You are not experienced with hot plastic handling; serious burns are possible

Strengths

Low-temperature design works with household heat sources like a hair dryer
Rubber sealing rings on nozzle and piston prevent plastisol leakage
Locking nozzle holds firmly in place during injection

Trade-offs

The injector becomes very hot during use and requires careful handling and gloves
Nozzle tip is not pinned or threaded; excessive pressure can cause dangerous splattering
Limited to small and mid-size lures due to the 120 ml capacity
