ITW: Dynamini, Dynamelt

Dynamelt S Series adhesive supply unit (ASU) is a computer-controlled hot-melt supply unit designed on metric standards. Its “all-icon” control panel, with choice of display languages, is internationally operator friendly. It is available for 120v, 240v or 380v service.

Available in four hopper sizes and with a choice of piston or gear pump, the Dynamelt S ASU uses a microprocessor temperature control to closely control the temperature of hot-melt adhesive for up to six hoses and six heads. The operator selects temperature set points for up to 14 zones, the system provides warnings and alarms for operator errors and system malfunctions.

The Dynamelt system provides accurate, proportionate temperature control for the hopper, hoses and applicators. Sequential heating delays may be programmed for turn-on of the hoses and heads. A “standby” temperature may be programmed so that the temperature zones can be maintained at a lower temperature when the ASU is not in active use, enabling rapid return to normal operation. With these flexible temperature programming features, the Dynamelt system increases adhesive life by eliminating prolonged high adhesive temperatures. It reduces energy consumption and brings the system up to normal operating temperatures in the shortest possible time.

A four-layered, shielded CPU board protects the microprocessor from external interference. The temperature control can interlock the parent machine with pre selected adhesive temperatures so that production automatically begins when adhesive temperatures are correct for the application. A simple and timely program sets the temperature values for the system. An optional remote control panel gives control and monitoring flexibility.

Digital readout of system conditions is provided. Optional external audible signals or lights which alert the operator to alarm conditions may be wired in. A security code can restrict access to system programming and parameters. The CPU monitors the electronic circuitry and provides alarms for error conditions.

The Dynamelt S ASU uses an extremely dependable, constant-pressure piston pump. This air-operated pump insures a high-pressure adhesive output from a low pressure, compressed air input. Piston pumps are available for either hot-melt or lotion applications. A gear pump is also available to assure a smoother and higher precision flow. The single or dual pump is driven by a single drive.

To combine high performance, precise control and better bond strength with up to 40% adhesive saving, ITW-Dynatec developed the Dynamelt S Auxiliary Wattage model which takes advantage of their innovative Dynafiber adhesive fiberizing technology.

The Dynamelt’s teflon-coated hopper accepts adhesive in all popular forms, including pellets, slugs and blocks. The ASU can accommodate air-actuated automatic applicators (heads), electric applicators, hand-held applicators and/or special applicators. Options available include memory card reader, pressure gauge, drop-in grid, pendant control and a seven-day scheduler.
