How much do you know about high-precision dispensing needles?

Precision dispensing needle is the metal needle of the metal needle at the top of the dispensing syringe. High precision dispensing needle is the dispensing needle with higher and more strict requirements for dispensing operation accuracy.

advantage

Avoid clogging and wire drawing

High flow / high precision / high cost performance

Products of different specifications are marked with different colors at Ruhr mouth

Patented thin-wall technology enables smaller diameter products to have larger flow

It is ideal for the application of heating process to reduce the waste of time in the cleaning process

Reduce the pressure on the delivery pump, improve the delivery performance and prolong the service life of the equipment

It is widely used in the research and development of thin-walled semiconductor products and precision dispensing needle technology.

2. How to select appropriate precision dispensing needle for dispensing machine?

Dispensing machine, also known as glue applicator, glue dropping machine, glue applicator, glue filling machine, etc., is specially used to control the fluid. The automatic machine that drips and coats the fluid on the surface or inside of the product can realize three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, no wire drawing, no glue leakage and no glue dripping. The dispensing machine is mainly used for the precise and accurate point, injection, coating and drip of glue, paint and other liquids in the product process to the precise position of each product. It can be used to dot, draw lines, circle or arc.

1. Four criteria: small dot - small dispensing needle, low pressure, large dot in a short time - large dispensing needle, large pressure, thick glue for a long time - inclined needle, large pressure, set the time as needed, aqueous liquid - small needle, small pressure, set the time as needed.

2. Fluids requiring special settings:

(1) Instant glue: for water-based instant glue, use safety and safety piston and Teflon lined metal needle; for thick instant glue, use conical oblique needle; if flexibility is required, use PP needle.

(2) UV glue: use amber syringe, white piston and inclined needle (can block ultraviolet rays).

(3) UV curable adhesive: use black opaque syringe and white piston, which can block ultraviolet rays.

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

(5) Sealant and paste fluid: if the rebound of white piston is serious, please use safe and safe movable type and inclined needle.
