Our first experience with manual overwrapping came several years ago when we purchased our first machine in response to our customers wanting a more professional look than the shrink wrap product we were providing at the time. So, we got our first machine and over time learned how to best use it. Part of that learning included what temperatures work best. If you set it too low it doesn't seal well and too high you can burn the film. We set that temperature years ago and have never changed it since.
Because we never change the temperature, when it came time to design the Xopax machines, we decided to have two different approaches to temperature control. Our goal was to design a basic system with a fixed temperature setting that is simple and easy to use while our upgraded system would allow temperature control and also provide us with a more durable electronics package that we could guaranty for three years. To that end we have ended up with what we are calling the PX Series and the PXC series.
So, the purpose of this post is to help you decide which one works best for you . The first question you should ask is what thickness film are you using? If it is something radically different than the 1 mil film that 98% or our customers use then you should strongly consider the PXC so you an adjust your sealing temperature to compensate for the different thickness. If you're going to use the standard film then your next question is how much use is the machine going to get used? If you are going to use it a lot, meaning daily use for extended hours and want it to last for years, then the PXC is your best purchase. We back this unit for three years too. If your volume is low, the PX is a strong choice for economic reasons alone.
The difference is in how we control the heat. With the PX we use some mechanical components that have a limited lifetime. These components on the PX are simple to replace by most end users and are going to be readily available from us. For this reason you don't need to worry about longevity but eventually the cost advantage may of the PX will deteriorate. We're talking hundreds of thousands of wraps before this would happen but we know some clients will wrap millions of boxes with our machines over years and years of use.
One more item to add here is that if you choose the PX and one day have regrets we will be able to upgrade it for a reasonable price.
