Manual dispensing machine has become a general equipment for industrial products. Needle barrel of dispensing needle and piston of needle barrel play a very important role in manual dispensing machine. The role of piston with small structure is neglected by most people. Many kinds of industrial dispensing syringes rely on piston to extrude glue better.

Why can pistons be used to recycle glue?
Workers can pull back the piston and suck back the excess glue properly when they operate the industrial dispensing syringe, because the space in the syringe will gradually increase after the piston is pulled out, and the air volume in the syringe will not increase, so that the pressure in the syringe is lower than that in the outside world. Because of the pressure difference, the atmospheric pressure will pressure the liquid into the syringe, which can solve the problem of industrial dispensing syringe. The effect of dropping low viscosity adhesive due to poor control of the backdraft force is little known, but it has practical operation value.
The material selection of needle piston is made of polyethylene, which has good low temperature resistance and chemical stability. It is a small accessory that provides fluency and convenience.
