What do you do when the tip is blocked

1. Increase the temperature to prevent needle clogging;

For example, hot melt glue uses stainless steel dispensing needle, glue can melt as long as it is heated, so as long as the heater is heated to a certain temperature, there will be no needle blockage.

2. Keep the consistency of the glue can prevent the needle plug;

Like the use of fast drying glue to process dispensing products, fast drying glue is fast curing at room temperature, if the break point glue in the dispensing process, it is easy to plug the needle, so the consistency of dispensing should be maintained.

3. If glue is not used, it is necessary to take the glue off to prevent needle clogging;

For example, AB glue, its curing speed is relatively slow, not so fast clogging phenomenon, but if you do not operate for a long time, or clogging phenomenon will occur, so this time you need to take off the mixing mouth, and then save the glue, so as not to plug the whole glue needle mouth.

4. Use needle of nanometer coating dispensing machine;

The dispensing machine coating needle is made of imported stainless steel, high precision, wear resistance, long service life, the internal cone design can prevent material blocking and hardening in the step part, maintain the high fluidity of the material.

The coating needle of the dispensing machine adopts nano-coating technology, only 2um thick, polishing the front end of the needle nozzle, which can effectively suppress the crawling glue and hanging glue phenomenon at the front end of the needle nozzle, and ensure the stability of the dispensing. Anti - adhesive, increase the yield of high - point glue. After 1000 hours cleaning agent immersion test, coating does not fall off, high corrosion resistance. After repeated testing for more than 180 days, the coating does not fall off until the tip of the needle is worn out, and the coating is long wear resistant. The coating has long life and can be used until the needle tip is worn. However, the coating of Teflon will fall off after only 20 hours of cleaning.

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, in order to prevent the blockage of the dispensing needle and ensure the production efficiency.
