LDPE (low density polyethylene) sheets are unique plastics that can be used in a lot of ways, including plastic containers and bags. It's also a material that takes well to welding. If you plan on performing this particular fabrication to these plastic sheets, use this advice as a guide.
Match Materials Correctly
If you're hoping to get quality welding on a consistent basis with LDPE sheets, then you need to make it a habit to weld materials that have the same characteristics. For instance, you need to weld LDPE sheets that are of the same variety and thickness. That's the best way to get welding results that are easy to repeat, regardless of how many times you have to perform the same type of welding activities. You can save yourself a lot of trouble by ordering the same variety from the very beginning so that you don't have to worry about there being variables that throw off how you're able to weld LDPE sheets.
Make Sure the Welder is at the Right Temperature
Your welder has to be set at the right temperature in order to weld LDPE sheets together, without causing material damage throughout this process. This is an easy factor to overlook, even for those that have welded different types of plastics for a long time.
Fortunately, there are devices that let you gather the exact temperature of your welder just before it's used on these sheets. Once you find out this temperature, make sure it's appropriate for the LDPE sheet variety you're working with.
Use the Same Pressure
You'll have to apply pressure when using a welder to combine different LDPE sheets together, but you need to verify the same pressure is used for each weld. Then you can get repeatable results for a better-finished product, whether you're using these sheets to make tubs or containers.
Before you begin welding LDPE sheets, it's a good idea to practice on materials that you don't really care about. Then you can figure out how much pressure to apply and how to keep it the same throughout your welding activities.
You can do a lot of things to LDPE sheets as far as fabrication goes. If you have a project that requires these sheets to be welded together, spend time setting up your welding environment, welder, and techniques that will come into play. Then you'll have an easier time combining these unique sheets together.

After I inherited my parents manufacturing business, I realized that there were a few challenges that they hadn't addressed earlier on in their careers. For starters, the company was missing several safety protocols that I knew could help to fend off injuries and accidents. I started focusing on bringing things up to modern code, but it didn't come without its share of challenges. I wanted to make this blog to help people to know how to identify and resolve challenges that could cause problems in the long run. Read more about this topic on this blog filled with great content about manufacturing.
