Advanced Troubleshooting Techniques

When it comes to Nordson glue machine troubleshooting, it’s important to have a good understanding of the advanced techniques that can help you quickly identify and resolve any issues you may encounter. In this section, we will discuss two such techniques: calibrating glue output levels and replacing faulty parts.

Calibrating Glue Output Levels

Calibrating the glue output levels of your Nordson glue machine is crucial to ensuring optimal performance. When the output levels are not calibrated correctly, it can lead to a variety of issues such as insufficient glue coverage or excess glue wastage. To calibrate the glue output levels, follow these steps:

  1. First, completely clean the glue system, including the tank, hoses, and nozzles, to ensure there are no residual contaminants that could affect the calibration process.
  2. Next, set up a test run with a small amount of glue and measure it using a precise scale or flow meter. This will give you an accurate baseline measurement to work from.
  3. Based on your specific application requirements, adjust the glue output setting on the glue machine. Start with a conservative setting and gradually increase or decrease it as necessary.
  4. Run a test pattern and observe the glue coverage. If the coverage is too thin or too thick, make further adjustments to the glue output setting until the desired coverage is achieved.
  5. Perform multiple test runs to ensure consistency in the glue output levels. Make fine adjustments as needed.

By accurately calibrating the glue output levels, you can optimize the performance of your Nordson glue machine and ensure efficient glue usage for your specific applications.

Replacing Faulty Parts

Another vital troubleshooting technique is the replacement of faulty parts in your Nordson glue machine. Over time, certain components may wear out or become damaged, leading to decreased performance or even complete system failure. Here’s a step-by-step guide to help you replace faulty parts:
