How to select dispensing needles?

How to select dispensing needles?

As the staff engaged in dispenser sales and the use of dispenser, the special selection and the rationality of the special disposable dispenser needle, when giving a lot of customers test machine, I always first from the company to select each dispensing needle 2 Because in the beginning you do not fully understand the customer‘s products need much glue, and some just started in a certain industry customers own product dispensing or dispensing equipment is completely do not understand. So you do not expect customers will help you, to the scene only their own slowly groping and transfer machine.

 

Dispenser needle selection principles:

Dispenser needle selection method: four criteria!

1.Small point - small needle, low pressure;

2.Short time big point - large needle, greater pressure;

3.A long time thick plastic - oblique needle, greater pressure;

4.According to the need to set the time water - based liquid - small needles, smaller pressure, according to need to set the time;

 

Here are several kinds of needles advised to users:

1.precision all stainless steel needle: specifications from 15G-25G

2.precision all stainless steel needle: specifications from 15G-25G

3. plastic seat precision dispensing needles: specifications from 14G-34G

4.all plastic oblique dispensing needles: specifications from 14G-27G

5.Teflon Needle: Specifications 15G 18G 20G 25G

6. pp around the needle series: Specifications 14G 15G 18G 20G 22G 25G

According to the need to set the time water - based liquid - small needles, smaller pressure, according to need to set the time.

 

More than the needle is also used for different viscosity glue, if you are the first dispensing then began to learn to slowly adjust the needle selection from small to large, dispensing speed from fast to slow, the pressure adjustment from small to large. Compared to the better liquidity of the glue, you can choose from the small needle, and then slowly increase the pressure, the speed from fast to slow. Especially in the process of adjusting the machine first mechanical reference point, this can prevent the operator due to mistakes and the coordinates of the wrong. As long as the beginning to set a good reference to the origin, with the needle at the original reference point on the OK, and then directly boot start.
