Automatic Dispensing Machine Needle Selection

2021-11-05

1. Select the appropriate dispensing needle for the process, depending on the type of adhesive
When choosing needles for dispensing, special attention should be paid to the adhesive used for dispensing. Since the type of adhesive is different, the needles used are naturally different. Many of the adhesives used in the dispensing process are basically the same. Dedicated needle. If it is a photocurable replacement dispensing process, generally speaking, a black opaque vacuum configuration is used and a needle with a white piston can block UV light. For UV glue, amber needles with white pistons are typically used in the dispensing process. When using other types of needles, the needles must be opaque to UV light.

2. Select the appropriate adhesive replacement treatment needle according to the treatment needs
Actual needs must be considered when choosing a needle for the dispensing process. For instant glue instead of glue, the process of choosing a needle is different. Water-based instant glue should use a safe piston. At the same time, you should also choose a needle with a metal lining. For thick instant glue, you need to choose a tapered needle.
Here's how to select a needle for the dispense process. This choice is very important for the entire dispensing process, as the use of irrational needles tends to result in no glue or discontinuity in dispensing. Mix randomly so that the needles do not interfere with the overall operation.

Silicone Injection Machine

The dispenser needle of the dispenser should be selected according to the nature of the adhesive.

1. Aqueous liquid is suitable for small adhesive needles, low pressure, set time according to situation
2. Thick glue Thick glue uses high pressure to set the time according to the situation and is suitable for diagonal dispense needles
3. Small dispensing needle, low pressure, short time.
4. Larger dispensing needle, high pressure and longer time

Silicone Extruder Machine Companies

The dispenser needle of the dispenser should be selected according to the type of adhesive.
Be careful with the following five types of special adhesives.
Instant Glue: For thinner instant glue, use a safety piston and lined metal needles. For thick, quick-drying water, use a tapered diagonal needle.
UV glue: Use an amber syringe, white piston, diagonal needle (can block UV rays). If you want to use other needles, please order us a needle that can block UV rays.
Photo-curing adhesive: Black opaque syringe, Japanese long-lived white piston, UV-blocking needle.
Anaerobic glue: Use a 10CC syringe and a white polyethylene universal piston.
Sealant and paste: If the white piston bounces badly, use a safe piston diagonal needle.
