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.

If you are continuing to experience issues, please contact us.  We can provide free telephone technical assistance.  We offer pump rebuild services also.

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.

Safety using Hot Melt

Hot - Do not touch!!
Did I say, "Hot, do not touch?"

Have you ever had molten adhesive on your skin?!?
If you have, "Hot, do not touch" is an understatement to you.

This first thing we want to do it wipe if off.....STOP, resist that urge because you will just spread the molten glue to more skin!!!!  Immediately cover affected area in clean cool water. Seek medical attention for removal of glue to avoid deep skin removal.

First, let's take the proper precautions so we aren't put in that situation, eh?

Before working on any hot melting equipment, such as Nordson, Valco/Melton, ITW, Slautterback or even a small simple glue handgun, be prepared.
  • Wear safety goggles
  • Wear heat resistant gloves (click here for gloves)
  • Wear long sleeve shirt or lab coat
Make sure to power down the equipment and give the equipment time to cool.  If you need to remove parts, use safety gloves and the proper wrenches.

Since glue machines are under pressure, be sure to turn off the pump pressure before removing any parts to avoid a burst of adhesive.

What Every Packaging Employee Should Know about Washdown

When it comes to overseeing hot melt machines and their operators in a packaging environment, one of the most common problems we see is failure of parts due to improper washdown procedure. Anyone in the packaging industry knows that the cost of hot melt parts can add up significantly over time
Inexperienced machine operators, lack of education by supervisors, and improper part selection can all contribute to premature part failure, which can substantially add to the cost of keeping your production lines running.  At Keystone Industries, we want to help you keep your hot melt machines running as efficiently and affordably as possible, so we took it upon ourselves to cover the most common topics surrounding washdown, and also talk about what the future holds for hot melt washdown.

The Importance of Washdown for The Packaging Industry

Many packaging and manufacturing facilities (especially in the food/beverage and pharmaceutical spaces) are required to wash down their machines regularly. This is to prevent bacteria and other harmful matter from contaminating the products that will be consumed by the end user. Washdown is also important for environments that experience large volumes of dust or small particles of packaging debris to ensure they do not interfere with proper function of the hot melt machine and equipment.

Two Common Problems Involving Washdown

Problem 1: User Error & Lack of Education

When it comes to electrical shortages from washdown, most problems are the result of one of two contributors: improper procedure by the operator, or an inadequate part. Most of the time, it is the former – inexperienced machine operators may not know which parts are resistant to water and which are not.  Of course, there is the possibility that the operator may be properly educated, but may just be careless in their personal washdown routine. While some user error is inevitable in many washdown environments, proper education is the best way to combat this problem.
As a supervisor or manager of your production environment, it is extremely important to thoroughly walk through the washdown process with each new employee. Ask them to repeat important points back to you, and quickly quiz them on the procedure after you run through it so you can be sure that they were paying adequate attention and retained the information. If you notice parts fail that you suspect are related to improper washdown, observe the employee during their next washdown to be sure they are following proper procedure. A few quick moments of education and observation of procedure can mean significant savings on failed parts.

Problem 2: Lack of Washdown Hot Melt Parts

Aside from user error and education, the other main contributor to part failure is simply the part itself being inadequate. For environments where thorough washdown is required, using standard parts simply won’t cut it. Standard hot melt parts are typically very prone to electrical shorting when they come in contact with any amount of water, rendering washdown very difficult, if not impossible using these parts.
Choosing a washdown hose or applicator head can help avoid part failure due to electrical shortages. These  hoses often feature a rubber sleeve or coating and a water resistant electrical connection that helps keep the electrical components of the part from getting wet.  The glue heads have a silicone gasket protecting the inside electronic connections and a matching water-resistant electrical connector. This is a great way to protect your hot melt parts from peripheral droplets or spray that may be created during the washdown process. These parts may be slightly more expensive than a standard part, but the cost savings you’ll experience due to the longer part life is well worth the additional investment.

The Limitations of Washdown Parts

Washdown hot melt parts are a huge step in the right direction for those looking to avoid electrical failure of parts in a washdown environment. At the same time, it is very important to keep in mind that these parts have their limitations. Because washdown parts simply protect the electrical components, the components themselves are just as susceptible to electrical shortages as standard parts if those components come into contact with water.
In short, a washdown part is more water resistant than a standard part, but this does not make the part fully submersible in water. Any attempts to soak, dip, or submerge the part in water will likely result in electrical damage to the part, so your washdown procedures should strive to avoid including any of these methods. If you use parts manufactured by Keystone Industries and want to know if a certain technique is safe for the parts, feel free to ask us!

Fault Log on Nordson ProBlue Melters

Did you know that your Nordson ProBlue glue melter records faults?  The melter stores the last 10 faults.  Do you have several production shifts running and all the faults seem to occur during the shift you are not available?

This could be your answer to finding out the root cause or at least identifying if faults are actually occurring.

Below are instructions on retrieving the fault log:

  • Press and hold the Setup key. Automatic scan stops and operating parameter 1 appears in left display.
  • Scroll left display to parameter 2 (fault log).  Right display indicates last fault that occurred as follows;  if last fault was a F1, F2 or F3, then the LED on the affected component key displays yellow.  If last fault was a F4, then LEDs on all component keys turn off.  The right display indicated the log entry for the last fault to occur.
  • Press the right display scroll key to review each of the remaining nine logged entries.  Each time the scroll key is pressed, the next older entry will display.  The log displays most recent fault first.
  • When finished reviewing log, press the Setup key to return to the automatic scan mode.

For information regarding each fault, refer to the complete manual - click here.

If fault indicates faulty parts, please call us to order parts.  If you are still having issues with identifying a resolution to the fault, please call us for free technical assistance.

Nordson ProBlue Manifold Heater

Did your Nordson ProBlue unit stop heating?  Could be the heater.  The heater (KNS0045 for 240V and KNS0046 for 480V) is cast in a protective block and  the complete assembly can easily be changed with 2 bolts and thermal grease.

It is very important to apply the thermal grease on the entire surface of the heater manifold. Spotty application can result in failure of the heater.

If this does not resolve the heating issue, you could have a faulty RTD sensor, faulty over temp thermostat or faulty circuit board.  Let us know if you need help troubleshooting.
