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.
Learn our top 5 tips for properly caring for your hot air welding tools and minimizing maintenance.
One of the most common mistakes we see our customers making when selecting a process heater is basing their choice on temperature rating rather than power rating. Temperature can be important but is generally a dependant variable. In this article we will discuss why the power rating is such an important parameter and some of the fundamentals needed to calculate your process requirements.
Together the VARIMAT V2, UNIROOF AT, and TRIAC DRIVE comprise Leister’s line of automatic welders for thermoplastic roofing materials such as TPO, PVC, etc. There are some key difference between these tools which make each suited to particular jobs on the roof.
In an air heater, air is blown over a resistance coil which is heated by a voltage applied across it. The temperature control of the air at the outlet of an air heater depends on the level of sophistication of the heater and any control systems with which it is integrated. Before discussing air heater control, first we will take a very high level look at system control.
Every plastic has a set of parameters (temperature, pressure, time/speed) at which it should be welded. However, the perfect temperature for the application can vary depending on environmental conditions. If you are welding in a less than ideal environment, the only way to find the perfect welding temperature for your project is trial and error. If welding is taking place outdoors be sure to perform test welds periodically throughout the day to ensure your temperature is set correctly, as the environment can change over time.
Patching is a quick and economical way to prolong the life of tents, tarps, and other items made from industrial fabrics.
Injection moulding is one of the most common industrial methods for high volume production of plastic parts. Plastic is heated until it reaches a thermoplastic state and is then injected into a mould. During this process a seam can develop on the part where different segments of the mould meet, known as the parting line. This seam of excess plastic is called flash. Flash must be removed from the part when it occurs in an area where surface finish is important or where it will cause an interference.
