Small and Deep Bores
The standard nozzle handles 99% of applications. For narrower or deeper bores, you can use a needle nozzle or a Luer Lock nozzle with a Fluid product like F20, and a Fill’in to free trapped bubbles.
Start with the Standard Nozzle
Change the standard nozzle only when its tip does not reach the bottom of the bore. F20 itself can be injected into holes down to a diameter of 0.1 mm.
The Needle Nozzle
The needle nozzle ends in a needle 0.9 mm in diameter and 25 mm long. Use it for small diameters that the standard nozzle cannot enter.
The Luer Lock Nozzle
The Luer Lock nozzle takes three interchangeable needles: 38 mm long (0.9 mm outside diameter), 100 mm (1.5 mm) and 200 mm (1.8 mm). You can use it for deep cavities and narrow passages. Contact us at Plastiform for other needles.
Fluid Products Only
Both the needle nozzle and the Luer Lock nozzle work with Fluid products only, mainly F20. A Pasty product is too viscous for a thin needle, so the pressure needed would break the needle or block the nozzle.
Chase a Bubble with a Fill’in
A Fill’in is a thin metal twist. In a very small bore, a bubble often stays stuck at the bottom. After injecting, insert the Fill’in and stir gently in circles to free the bubble and let it rise. Stay gentle, because a sudden movement can deform the impression while it is still fluid.
