What to do when the dispensing tip is blocked

1. Raising the temperature can prevent the needle from clogging;

For example, the hot melt adhesive uses an all-stainless steel dispensing needle, and the glue can be melted as long as it is heated, so as long as the heater is heated to a certain temperature, the needle will not be blocked.

2. Maintaining the consistency of dispensing can prevent needle blockage;

For example, when using quick-drying glue to process dispensing products, the quick-drying glue cures quickly at room temperature. If the dispensing is interrupted during the dispensing process, it is easy to block the needle, so the continuity of the dispensing should be maintained.

3. When glue is not used, the glue needs to be removed and stored to prevent the needle from clogging;

For example, AB glue, its curing speed is relatively slow, and it will not cause clogging so quickly, but if it is not operated for a long time, clogging will still occur, so it is necessary to remove the mixing nozzle at this time, and then put the glue Store it well so as not to block the entire dispenser port.

4. Use the needle of the nano-coating dispenser;

The coating needle of the dispensing machine launched by Alessis is made of imported stainless steel, which has high precision, wear resistance and long service life. The inner conical design can prevent the material from clogging and hardening in the step part, and maintain the high fluidity of the material. .

The coating needle of the dispensing machine adopts nano-coating technology, with a thickness of only 2um. The front end of the needle nozzle is polished, which effectively inhibits the glue climbing and glue hanging at the front end of the needle nozzle and ensures the stability of the dispensing. Anti-adhesive, improve dispensing yield. After 1000 hours of cleaning agent immersion test, the coating does not fall off and has high corrosion resistance. After 180 days of repeated testing of needles, until the needle tip is worn out, the coating does not fall off, and it is resistant to wear for a long time. The coating has a long life and can be used until the needle tip wears out. However, the Teflon coating will fall off after cleaning for more than 20 hours.

The glue and process used in production are different, and the solution will be different, so it is necessary to take measures according to the actual situation to prevent the clogging of the dispensing needle and ensure production efficiency.
