Some of the major benefits of this plan are:

  • Increasing the overall life of your hot melt equipment.
  • Reducing down-time.
  • Reducing the cost of replacement parts and repairs.
  • Increasing the overall efficiency of your packaging and/or assembly processes. 

The ADQ Service Plus program is exclusively for customers that purchase an average of at least 1,500 lbs. of adhesive per month and replacement parts  directly from ADQ, Inc. Although it is not being implemented as a contract plan, it is understood that the Bi-yearly equipment services are to be performed to each piece of hot melt equipment, as long as the hot melt adhesive products being used in the system(s) is purchased from ADQ  Inc. Hot melt equipment services will always be scheduled during normal business hours, Monday through Friday, unless otherwise stated in program details. The service schedule will start immediately with the first purchase of adhesive and on six month intervals afterward.

With each service the following task will be performed:

  • Removal and cleaning of tank inlet screen.
  • Inspection and clean out of electrical control cabinet.
  • Inspection and lubrication of air motor or gear pump system.
  • Inspection and clean out of air control filter / regulators.
  • Complete low-temp flush of each hose and gun body.
  • Replacement of tank high-pressure filter and o-ring.
  • Replacement of all gun filters.
  • Inspection and cleaning of all nozzles.
  • Complete report on system condition, additional recommendations, and placement of dated service tag on unit.

  HOT MELT EQUIPMENT TROUBLE SHOOTING GUIDE

 This guide assumes that the proper adhesive is in use and calls for equipment adjustments to cure symptoms arising from equipment wear or mal-adjustment or from incorrect operating procedures.  Adjustments should be made with care so that adhesive performance is not adversely affected. 

      OBSERVATION                                   POSSIBLE CAUSE                                                             SUGGESTED SOLUTION 

SMOKE

1)     Temperature of hot melt too high.

2)     Excessive exposure to air.

1)     Reduce temperature of melt tank.

2)     Keep pot covered at all times.

GELLING

1)     Temperature of hot melt too high.

2)     Incompatible adhesives.

1)     Reduce temperature.

2)     Flush system and refill.

ARRING

1)     Temperature of hot melt too high.

2)     Overheating reservoir walls.

3)     Oxidation of adhesive.

1)     Reduce to recommended temperature.

HOT MELT EQUIPMENT TROUBLE SHOOTING GUIDE

 ISSUES TO CONSIDER FOR SUCCESSFUL HOT MELT OPERATION

 Assuming that the hot melt adhesive used is within specification and that it has been tested and used successfully, there are several areas where faults occur:  packaging stock, application of adhesive, and compression of adhesive.  Below are points to consider about each area which could help prevent a problem from occurring.

PACKAGING STOCK

  • Has the packaging stock been changed? i.e. Polyethylene board, grease resistant or recycled board?  Has the packaging stock supplier been changed?  Different packaging stock suppliers have different board suppliers.
  • Are the dimensions of the packaging stock correct?  If the packaging is either too big or too small, it cannot be compressed properly.
  • Has the packaging been scored properly?  Bad scoring results in increased spring in the flaps.
  • Has a blanked out area been left for the adhesive, and is it correctly positioned?  Has the packaging stock an all over varnish?  Certain varnishes are extremely difficult to bond, and require special hot melts.
  • Is the clay coating adequately bonded to the board?  Poor Clay coating will result in a very weak bond.
  • Is the packaging stock stored in dry cool conditions?  Hot melt will not bond very cold wet board stock.


APPLICATION OF HOT MELT

  • Is the machine running at the correct speed?  Unless the speed of the application is constant, any variation in the speed of the machine will alter the length of open time. 

  • Are the temperatures of the adhesive applicators correct?  Any variation of the temperature will alter the open time of the adhesive. 

  • Is the adhesive being applied in the correct position?  Is the correct amount of adhesive being applied?  Again, any variation to the correct quantity of the adhesive will vary the open time of the adhesive. 

  • Are the tanks being refilled regularly?  If the tanks are allowed to run down before filling with adhesive, a temperature drop will occur which will shorten the open time of the hot melt. 

  • Has the atmospheric condition of the plant changed? Heat/Humidity.

COMPRESSION ISSUES

  • Is the compression positioned accurately to compress the adhesive bead? If the adhesive bead is not compressed, the flap will pop open on leaving the compression. 

  • Is the compression of the correct strength? It should not be too loose so that the adhesive is not compressed, or too great as to crush the package. 

  • Is the package at 90° to the compression?  If the package is out of square to the compression, only two diagonal corners will have adequate compression.
  • Is the compression absolutely straight and not tapering? 

  • Is the open time to compression appropriate for the adhesive choice and/or temperature settings?
