How to choose the right needle for the dispenser?

The dispensing machine is also known as the gluing machine, the gluing machine, the gluing machine, the gluing machine and so on, which is specialized in the control of the fluid. And the fluid drip, coated on the product surface or product internal automation machine, can achieve three-dimensional, four-dimensional path dispensing, fine. Position determination, precise glue control, no wire drawing, no glue leakage, no glue drop. Glue dispenser is mainly used for glue, paint and other liquid in the product process. Correct point, injection, coating, drip to each product essence. The position can be used to achieve a dot, a line, a circle or an arc.

How to choose a precision dispensing needle?

1. Four guidelines: small point - small precision dispensing needle, low pressure; Short time big point - large precision dispensing needle, large pressure; Long time concentrated glue - inclined precision dispensing needle, large pressure; According to the need to set the time of water-based liquid - small precision dispensing needle, small pressure; Set the time as needed.

2. The dispensing machine needs to set the fluid:

(1) Instant glue: the use of water-based instant glue. Full type piston and TEFLON lined with metal needle, for instant thick glue, use conical inclined needle, PP needle if flexible.

(2) UV glue: the use of amber needle, white piston and oblique needle (can block ultraviolet).

(3) Light curing adhesive: Use black opaque needle barrel, white piston, can block ultraviolet needle.

(4) Anaerobic glue: Use 10cc syringe and white PE universal piston.

(5) sealant and paste fluid: if the use of white piston rebound serious, please use Ann. Full movable type, using oblique needle.
