The choice of dispensing machine needle
How to choose the dispensing needle:
1. Four guidelines: small point - small needle, low pressure, short time big point - large needle, high pressure, long time ——Small needle, less pressure, set time according to need.
2. Fluids requiring special settings:
(1) Instant glue: use a safety piston and a Teflon-lined metal needle for water-based instant glue, use a tapered oblique needle for thick instant glue, and use a PP needle if flexibility is required.
(2) UV glue: use an amber syringe, a white plunger and an oblique needle (which can block UV rays).
(3) Light-curing glue: Use a black opaque syringe, a white piston, and a needle that can block ultraviolet rays.
(4) Anaerobic glue: use a 10CC syringe and a white PE universal piston.
(5) Sealant and paste fluid: If the rebound of the white piston is serious, please switch to the safety type and use the inclined needle.
