Quick take

Aluminum injector for pouring hot plastisol into lure molds to make custom soft baits.

A 45 ml aluminum injector for pouring hot plastisol into molds when making your own soft plastic baits. It has a 5/8 inch nozzle that fits most stone or aluminum molds, a locking nozzle cap and rubber sealing rings at the nozzle and piston. At 1.5 ounces with a plastic handle, it suits small and mid-size baits under about five inches.

Best for

  • DIY lure makers building a library of custom plastic baits
  • Anglers wanting specific colors and profiles not available commercially
  • Crafting baits optimized for particular local fishing conditions

Skip if

  • You cannot work safely with hot plastisol temperatures

Strengths

  • 45 ml capacity suits small to medium-sized baits without excessive weight
  • Locking nozzle prevents accidental plastisol exposure
  • Aluminum construction balances durability and weight

Trade-offs
