This is RF (or radio-frequency) welding, and is how we've built our vinyl tarps here in America for over 30 years. Two pieces of vinyl are placed under a bar that comes down and presses against the fabric resting on the table. High frequency waves are passed through the area where the bar and table...this is where the weld takes place. This RF field causes the molecules in the vinyl to move and get hot. The combination of the heat under pressure creates the weld.
Building tarps this way is more deliberate than the standard hot-air weld that most tarp companies use today. The method in which we weld creates a stronger bond because it essentially turns 2 pieces of vinyl into one piece...leaving incredible strength and watertight seal. Essential for the quality our customers expect from our tarps.
Let us prove to you that we can make a tarp better than what you are using today. Call us today and we'll build a tarp worthy of your hard-earned dollar.
Keep safe,
Harp's Tarps
