Hot melt adhesive bonding is a cheap and effective method for joining various materials. Whether using automatic or manual spray coating, the bonded area provides better stress distribution, greater fatigue resistance, and higher strength than conventional joining methods. Industrial Challenges The biggest problem that hot melt users face is the uniformity of the spray. Reciprocating pumps, such as diaphragm or plunger pumps, produce a change in pressure and flow. To compensate for this, more hot melt adhesive must be used to spray the target area. Too much spraying results in additional material waste and increased manufacturing costs. The use of hot melt adhesive also takes into account its high viscosity, high operating temperature and high accuracy requirements of the pump. The viscosity of a hot melt adhesive is typically around 500 poise at an operating temperature of 300 to 400 ° F. The exact accuracy of the pump will be important to apply the exact amount of hot melt to the specified range. Zenith Solutions The pumps used to spray hot melt adhesives are generally positive displacement gear pumps. This high-precision pump must have the ability to deliver highly viscous fluids and operate at high temperatures. Zenith precision metering pumps deliver exactly the right amount of flow to the applicator without ripples and at the same time generate the necessary pressure to meet the system's requirements. How You Benefit from Accurate Continuous Feed - General hot melt equipment includes a hot melt unit that supplies one to four metering pumps. With the Zenith precision metering pump, the hot melt can be accurately metered and delivered to the applicator for precise, smooth flow and continuous flow, which greatly eliminates overspray and avoids material waste and increases throughput - Reduce operating, manufacturing and maintenance costs while increasing production. Zenith's planetary metering pump can be mounted directly to the applicator and supplied with a cheap delivery pump. A planetary pump up to 32 outlets, can greatly improve the volume. Improve quality - Manufacturers and users of gluing equipment can greatly improve product quality and reduce waste by using Zenith metering pumps. Whether existing equipment or new equipment, can reduce the size of the device, simplify equipment configuration, reduce maintenance costs, while maximizing production.
