Package Purchase | Basics of Spray Guns (Dispensers)
Manufacturing process:
The main components of the spray gun are basically ABS, PP, PE, EVA and other plastics, some of which are covered with a layer of aluminum cover and a layer of electrified aluminum. Spray gun components are mainly through the injection molding process molding. Among them, glass beads, springs and other metal parts, gun factories are generally outsourcing procurement. The main components of the spray gun, such as some housings, can be applied to electroplating, electrified aluminum, spraying, injection molding color and other ways.
Product structure:
2.Accessories DescriptionExisting hand-clasp sprayer by the shell, Kiga, spring, glass ball, gaskets, screw teeth, suction tube, valve, nozzle, wrench, piston, sub-posts and other components of the combination.
3. Working principle by pressing the wrench, the piston in the piston hole sliding upward, the liquid through the suction pipe inhalation through the gun body channel and blocking parts of the inner hole, by the water distribution set of water distribution holes and the head cap nozzle hole was mist spray; relax the wrench, the piston reset under the action of the spring, the continuous manipulation of the wrench a buckle a loose, the liquid will be continuously sprayed in the form of a mist.
Procurement matters:
1, spray gun due to the components of the more, therefore, the development of new products, try to choose the male mold products, otherwise the cost of molding. Otherwise, the cost of molding is high and the cycle time is long.
The connection between the gun body and the gun shell is not firm, and the gun shell is easy to fall off in the process of using and transporting;
2. The blocking parts that play a role in sealing the air are cylindrical and rubber parts, with no resistance to aging, acid and alkali, and in the conditions of temperature change, such as under o°C, the products start to harden, lose the function of sealing the air and be contaminated by the liquid, leading to deterioration and corrosion, and lowering the service life of the whole machine, and the atomization effect is poor and the particles are big.
