How to choose the best striker for dispensing: dispensing needles

From the beginning, I was confused about the dispensing consumables and equipment, and now I can derive product information from my brain as soon as I say the model or see the picture. This process has taken a long time. The application of glue has gradually penetrated more and more industries, and how to better realize high-efficiency dispensing has become the focus of more glue dispensers.

As a person engaged in the sales and use of dispensers, I am well aware of the importance and rationality of the selection of dispensing needles. In the dispensing process, the glue flows directly from the needle to the designated position of the dispensing, and the dispensing needle acts as the most forward player in dispensing. The choice of dispensing needle is directly related to the effect of dispensing! Sometimes we encounter the glue coming out too slowly, the efficiency is not high, the size of the glue dot is not up to the requirement, either too small, or the glue dot is too large, the needle is blocked by the glue, the needle is corroded, etc. These are all related to the needle. The selection is related!

1. Four basic principles for the selection of dispensing needles:

1. Smaller point-small (corresponding to the G-number) dispensing needle, low pressure, short time;

2. Larger point-large (corresponding to a small G number) dispensing needle, greater pressure, longer time;

3. Thick glue-oblique dispensing needle, high pressure, set time according to need;

4. Aqueous liquid-small dispensing needle, low pressure, set the time as needed.

2. Fluids that need special settings:

1. Instant glue: For water-based instant glue, use a safety piston and Teflon lined metal dispensing needle. For thick instant glue, use a tapered TT oblique dispensing needle. If flexibility is required Use PP flexible dispensing needle.

2. UV glue: use amber dispensing syringes, white pistons and TT oblique dispensing needles (UV-shielding). If you use other types of dispensing needles, please order a dispensing needle with UV-shielding from our company.

3. Light-curing glue: use black opaque dispensing syringes, white pistons, and UV-shielding dispensing needles.

4. Anaerobic glue: use 10CC dispensing syringe and white PE universal piston.

5. Sealant and pasty fluid: If the white piston rebounds severely, please switch to a safety piston and use a TT oblique dispensing needle.

6. Apply the glue primer on the wide surface: use a white soft or yellow bristles brush with suitable flow to brush the surface to dispense the glue needle.

3. Specifications of commonly used dispensing needles:

1. Precision all-stainless steel dispensing needle: specifications from 10G-30G

2. Precision all-stainless steel double-dispensing needle: specifications from 10G-30G

3. Screw-type plastic-steel dispensing needle: specifications from 14G-34G

4. Bayonet plastic steel dispensing needle: specifications from 16G-34G

4. TT oblique dispensing needle: specifications from 14G-27G

5. Teflon dispensing needles: specifications 20G, 25G, 27G

6. pp flexible dispensing needle: specifications 14G, 15G, 18G, 20G, 22G, 25G

7. Brush dispensing needle: specifications from 14G-34G

The above is the detailed information of the dispensing needle, which is provided by the dispensing equipment itself. If you have any questions about the selection method of the dispensing needle, please contact the company for further information on the selection method of the dispensing needle.
