This model is operated by air vale so that it is useful to require high viscosity, high pressure & high speeding of hot melt adhesive. Air valve operating is better than electronic valve operating because of short closing time and not to change pump pressure & speeding velocity. Easy to control valve clearance and hot melt flow rate.
This is good for high viscosity hot melt adhesive, in case of using the module it is no problem on short hot melt injection flow, having enough to the air chamber even though low pumping pressure sufficient efficiency of pumping should be accomplished, on the big size of piston needle, the pump performance is under good condition and reliable long run operating.
This model is specially manufactured, using spiral pattern type of module the pump R.P.M is no changing under variable viscosity & pump pressure, it is available to control hot melt flow rate on the adjusting valve clearance.
This model is operated by air valve so that it is useful to require high pressure & viscosity of hot melt, specially it has a advantage to the returning speed.
Zero cavity module is linked directly with nozzle and needle. Hot melt's interception ability is excellent, and can control needle's distance and spring's compressive strength finely. So, injection pattern is correct.
