Tankless Hot Melt Systems - The Truth

Before sinking an enormous amount of capital into a tankless hot-melt system, make sure you know the cons as well as the pros that the adhesive melter company is selling you.  Remember, they will tell you only the good side and before you know it, you are writing a big whopping check without knowing the full picture that may affect your type of packaging application.

Below are the selling points you will hear and what that truly means:

·        Tankless take up less space:  In order to set up the temperature controls, feeders and stands, the space used is as much and sometimes more than the conventional hot melt systems.  They are referencing the unit only when making this statement.

·        Less time in “Warm-up” phase:  Since most packaging plants run 24 hours a day, this is not a benefit….the units are already hot from shift to shift.  Also, the conventional hot melt units have a timer that can be set to heat before a shift begins.

·        Less time used in filling:  Since tankless technology involves feeding small quantities of dry pellets into the heat on demand system, there are 2 factors that can come into play that can cause downtime:
o   Clog in feeding system
o   Unit runs out of glue (you cannot manually fill this system)

Proven & Dependable conventional melters:  Melt rate times on standard melter reservoirs are 40 minutes up to 2 hours, depending on size of unit.  Many people use less expensive adhesive feeders that supply these conventional units and only fill the feeders once per shift.

Using your current Adhesive with tankless systems:

Did you know only certain adhesives can be used in the tankless units?  You may not be able to keep your current adhesive.  Not all packaging grade adhesives will blow properly in the tankless systems.    Before you write that big check, make sure your specific adhesive is compatible, otherwise, you may be spending months testing glues that will work with your application.

The tankless system sounds like a great new idea, but practically, it is not for everyone.  The benefit to those who are able to meet all the criteria is less char build up in the tank.  With periodic preventive maintenance, which is probably already scheduled on your conventional units, control is kept on reducing any char issues in the tank.  Hoses and heads have the same char issues in either scenario since they have to remain heated.

ProBlue Under Temperature Fault F2

There are a few reasons you can experience an under temperature fault on your Nordson ProBlue unit.  Many people do not think about this particular cause discussed below.
ProBlue units circuity monitors the manifold temperature every 15 minutes after the "heaters" button is active.  If the line voltage is low in your plant, the manifold may not reach the expected set temperature with in the 15 minute time frame set in the software.  In this case, the unit will display a F2 fault.
There is a remedy for this situation.  You can reprogram the unit to give the unit 30 minutes to heat instead of the default 15 minutes to heat.
One simple step on the circuit board will make this change:
Press and hold the "heaters" and "pump" buttons together while powering up the glue melter.  During power up, the unit will display the code of Lo17O which indicates the 30 minute set time.
If you want to change the unit back to 15 minutes, repeat the process.

Proper Glue Hose Installation for Nordson & Other Glue Melters

Improper routing and installation of a glue hose can shorten the service life.  With a few simple steps, you can maximize the life of the glue hose, keep employees safe and keep your production lines running.
Proper hose length
For areas where hoses will be installed in a straight line, the length must be longer than the distance from port to port. As the hose is heated, the diameter increases to contain the force of the glue and the length will decrease. Some hoses have decreased in length up to 2 inches. 
In this case, if the hose is too short and there isn’t enough slack, the hose fitting connections will be under stress, causing a possible leak.  Even worse, a catastrophic failure of the hose breaking loose from the fitting could occur causing pressurized hot adhesive to flow.
On the contrary, too much slack can introduce new issues, such as, hose abrasion and snagging on other machine surfaces.
Proper bend radius
Adhesive hoses are somewhat flexible, but have bend radius limitations.  The hose core, fitting crimps and electrical components can be stressed to the point of failure if the hose is bent beyond the maximum recommended bend radius.  Call Keystone (800-235-8090) for your hose’s specific recommended maximum bend radius. 
Regarding the fitting crimps and bending near the fitting, the suggestion is to keep the hose straight for twice the hose outside diameter.  If the hose OD is ½”, keep the hose “straight” beyond the metal fitting for a minimum of one inch.  If this is not possible, consider using 90 degree or 45 degree elbow fittings with insulator jackets to accomplish the angle needed without stressing the hose.

Avoiding hose twist
Metal hose cores in a glue hose have mechanical strain limits with regards to twisting.  Tighten fittings using two wrenches or “double wrenching”; one to hold the fitting from twisting and the other to tighten the hose connection.  To further prevent twisting, limit bending motion of the hose to a single dimensional “plane” when routing.  A hose bending only left to right, only up and down or only forward and backward is moving in a single plane.  Any combination of left/right, forward/backward, and up/down movement represents 2 planes of motion and all three represent 3 planes of movement.  A compound bend can occur with multiple planes of motion and this can cause the hose to twist, since the hose ends are fixed and held tight.  Try to limit routing to a single plane, but, if your application requires hose movement to cross multiple planes, ask a Keystone rep for a recommendation.
Abrasion and Attachments
Another cause of premature hose failure is abrasion of the outside hose cover, exposing insulation, wiring and possibly the hose core.  Live wires being exposed is a safety issue and should be avoided at all cost.  Use proper hose hangers and keep moving hoses from rubbing against other surfaces.  Clamps, zip ties and any other restrictive attachments should not be used on hoses since they can press on the wiring and cause hot spots.  These hot spots will cause untimely hose failures and could burn through the metal hose core causing an unsafe catastrophic failure. 
By following these simple suggestions, you can maximize the service life of your glue hoses.  Call or email (sales@keystoneparts.com) Keystone with any questions or requests for recommendations. 
Keystone manufactures hoses for Nordson®, Slautterback®, ITW®, HMT®, Graco®, Valco/Melton®, Klebtec® and other  hot glue melters for a fraction of the cost of the OEMs. Warranty provided is equal to OEMs.

Nordson Pump will not hold Pressure

Is your pump shifting too much?
Is the pump losing pressure?

You may have contaminants in the bottom check ball.  Erratic shifting can be a symptom. Before you spend big money and buy a new pump, check this area first.  You could save yourself a lot of money in downtime and not need to buy a pump.

See No. 18 & 19 below.

Motivating Production Employees

There are many good ways to motivate production workers....first, it takes the right attitude and a safe, clean, well organized and well lighted environment. 
Money is the main incentive.  Make sure your production workers are adequately paid and have a chance to earn more. If each worker has a chance to move within the company to a better job that pays more money or they have ways to control what they make, that is incentive.
  • Piece work and performance based bonus' can provide the worker an opportunity to control their pay.  With piece work, you need a good quality control department to guarantee the speed of work is not compromising the quality.  If you already have great quality control, this may be a win-win for you and the employee.  Performance bonus' set the expectation and the worker knows the boundaries and how to achieve maximum pay.
  • It is important to make known to the employees that they are a valuable part of the team. Praise employees when it is due.  Employees appreciate being part of the team.
  • Make sure that anyone who supervises your production workers is fair, reasonable and understands the work that is being done. The manager needs to be able to coach the employees and help them to grow.  Few things make for worse morale than an unfair boss. and/or a supervisor who can't coach workers when they have a job-related problem.
  • Empower the employees as much as possible, by letting their ideas be heard.  After all, they are the ones working the assembly lines all day.  Maybe they have good ideas on how to improve efficiency.   
  • All of these items will go a long way in keeping staff happy and in tune with making quality products......a win for all involved.
