We often get requests from customers for assistance building a heat solution for drying or adding heat to an existing drying system that is under-performing. This is understandable, using heat to dry is a common occurrence in our everyday lives from clothes dryers to hair dryers. In this article we explore why hot air is not always the best drying solution and talk about using fast moving air as an alternative to heat. We also give guidelines to help you decide when to use heat and when to only use air.
We often get questions from customers about the VARIMAT V2 and the BITUMAT B2. These machines seem similar on paper but are specialized to deal with specific roofing materials.
Thermocouples are widely used to measure temperature in industrial processes. In this article we will explain how a thermocouple works, when you should use one, and some best practices for use.
Knowing which type of plastic you're working with is a cornerstone of good plastic welding. By asking you to perform a few simple tests, such as a flame or burn test, the flow chart below will help you determine which type of plastic you have.
Why is using the correct tool for the job important? Results.
Using a tool that is undersize for the job will give you unsatisfactory welding results. There are two factors at play: power and weight.
When installed and operated properly, an air heater should have a long service life. However there are many common pitfalls that can cause problems and shorten the expected lifespan. This article discusses our recommended best practices for installing air heaters to avoid the most common errors that shorten tool life.
Keep an eye out when buying used (and even new!) equipment to make sure the nameplate is intact and hasn’t been altered in any way. We’ve helped a few customers deal with serial numbers cut or scratched out of nameplates. The serial number is the easiest way to confirm age and ownership of a Leister tool. Without a serial number, the manufacturer’s warranty is unusable. You could even be purchasing a stolen piece of equipment. Don’t get caught! Check before you buy.
The serial number has been cut out of the nameplate on this tool and a poor attempt has been made to cover the resulting gap with black marker. This tool was purchased brand new from an unauthorized distributor. The equipment was not electrically certified for use in Canada and had not been modified to be compliant with the Canadian Electrical Code. The tool carries no warranty as a result.
Test welds are an important part of welding thermoplastics whether they’re used for roofing, tarps, pools, tunnels, landfills, or tailings ponds. Welds should be tested first thing in the morning and several times throughout the day to ensure that environmental changes are not compromising the strength of your welds.
Both regenerative and centrifugal blowers are widely used in industrial processes. Superficially the two types of blowers can seem similar and it can be difficult to find good information on the differences between the two types of blowers and why one would be selected over the other.
First, we’ll discuss what the two types of blowers have in common. Both types move air using an impeller on a rotating shaft. The air comes in the inlet and is focused while traveling with the impeller before exhausted as linear flow at the outlet. This is where the similarities end.
Plastic extrusion welders can generally be divided into two categories: screw-based extruders and non-screw-based extruders.
