How to choose and align the needle of precision dispensing machine?

In the dispensing process of precision dispensing machine, if the precision dispensing needle is not selected correctly, there will be problems such as too small or too large glue spots. Therefore, how to select the needle in the dispensing process of precision dispensing machine is particularly important.

When dispensing, the precision dispensing machine needs to choose different needles according to different glues. Instant glue uses a conical oblique needle. If you need flexibility, choose PP needle. UV glue: use white piston and inclined needle, or customize the needle that blocks ultraviolet rays. Light curing adhesive: use a black opaque needle.

Selection method of precision dispensing needle. When the dispensing point is small, choose a small needle with low pressure. If you need to be bigger in a short time, choose a large needle, which has high pressure. If you need a long time to use high-strength glue, choose an inclined needle, which has high pressure. When dispensing, you need to set the dispensing time and glue with low viscosity. Select a small needle and set the time according to the demand.

Several sizes of common precision dispensing needles:

1. Precision all stainless steel needle: specifications from 15g-25g

2. Plastic seat precision dispensing needle: specifications from 14g-34g

3. All plastic oblique dispensing needle: specification from 14g-27g

4. Teflon needle: specification 15g, 18G, 20g, 25g

5. PP flexible needle series: specification: 14g 15g 18G 20g 22G 25g

Needle alignment method of dispensing machine

The precision dispensing machine can automatically align the needle through system control. If the needle needs to be adjusted when replacing the precision dispensing needle, fine adjustment can be made after replacing the needle. Precision dispensing machine is equipped with deviation adjustment function. In case of needle alignment problem of dispensing machine, it is best to find the manufacturer of dispensing machine for guidance before operation.
