Tonneau Cover

Injection/compression molding was used to produce this lightweight (65 lb), thin-wall lockable tonneau cover, allowing a much smaller press to be used. Once molded, top and bottom halves, reinforcement bars and assembly clips are added and the two halves are vibration welded. One of industry's largest high-frequency vibration-welding machines is used to bond up to 70 in.2 of welded surface. The PP grade used was specifically formulated to reduce warpage and facilitate proper welding/assembly.

  1. Hi people,
    Thank you so much for this wonderful article really!
    If someone want to learn more about Tonneau Cover I think this is the right place for you!

  2. Choosing the right cover for your pickup will depend on how you use your truck. All our tonneau covers offer protection and cut down on drag. So the question is: which is right for you? Consider what the primary reason for your cover is and what level of peace of mind and security you want. Also, how often do you need full access to the entire length of your truck bed? What is the best F150 Bed Cover on the market? Tough questions. Let's try to answer them each in turn.

  3. Good post. I'm happy to hear that the lightweight PP grade tonneau cover is easy to weld. It will make it easier for me when I need new parts, and it should be much less expensive too! Also, at https://www.techplaastic.com/thermoset-injection-moulding-india/, we never sacrifice quality for weight and were able to use injection moulding as well!
