DIY welding unit for door sealings

If you’re a small or medium-sized trailer builder, you probably know how nice it would be if you could make door sealings in your own workshop instead of having to wait for delivery.

Well, now you can. Just use Primo’s new, compact welding unit and make those door sealings in your own workshop. Come and try it for yourself at our IAA 2016 booth!

Primo offers a wide range of extruded profiles to the transport industry – including one of the most critical parts of a trailer door: the door sealing.

Now, Primo introduces a new welding unit for door sealings that makes it possible for trailer builders to make their own door sealings quickly and with outstanding results. For many small and medium-sized builders, there are plenty of benefits to be gained from making the door sealings in their own workshop, not least in terms of economy and lead times.

That’s why we have chosen to showcase our newly invented welding unit at this year’s IAA in Hannover – and invite everyone to come and try it at our booth.

Precise cutting and strong corner welds

The newly developed welding unit is compact and easy to operate, and makes it possible to produce door sealings of any dimensions in a matter of minutes. It’s just a matter of choosing the right door sealing profile for the trailer in question. The operator then uses the built-in cutting tool in the welding unit to trim the profiles cleanly and precisely, and the critical corner welding takes just a few minutes to complete.

Once the door sealing is finished, it can be glued directly to the trailer body using a special glue called Bondafin, and the trailer door is now ready for years of carefree operation.

Excellent material properties

The profiles themselves are made from extruded TPV, a strong and flexible vulcanised rubber ideal for door sealings. TPV prevents ice from forming on the rubber itself, which means that for cooling and freezing trailers, opening and closing the doors will always be safe and easy under any temperature conditions. The Bondafin glue ensures perfect fit and tight closing in order to protect the precious goods inside, even after thousands of opening/closing cycles.

Try it at our booth

And the best part? It takes an operator just a few hours to learn to make perfect door sealings with our welding unit and our specialised door sealing profiles.

At our IAA booth, you can come and have a go at cutting and welding profiles yourself – just drop by and see for yourself how easy it is to create perfect door sealing right there in your own workshop.
