Inserting Staple into Device

Simply insert the staple of choice into your PlasticWeld Gun. 

It is normal to apply some force in inserting the stapler so that the device has a firm hold on the staples. Even if you softly insert only the tip of the staple in the device, the staple will still heat up.

Staple Heat Demonstration

As you press on the trigger, the LED indicator light will not only help provide lighting in dark environment, it can also help you distinguish if the PlastiWeld is in the process of heating up the stapler.


Important Tip:

Due to it's metal properties, every time you reheat the same stapler, it will take a longer each time to heat up. 


Example: If you are heating the stapler for the first time, it would take a few seconds to glow red. If you heat the same stapler 3 times, it would take a longer to glow red.

The Perfect Weld Technique

Step 1. Setup where you'd like to place your weld. 

Step 2: Press on trigger and slowly press onto plastic surface.Be mindful of how thick your plastic is. You will need to gauge how far in you'd place the staple in. Preferably aim in the center of the plastic. 

Step 3: Timing. If you overheat your staple (turns red hot) then it will liquify the plastic. Let go of the trigger the second after the staple starts melting into the plastic to prevent overheating the staple. 

Step 4: Wait 10 seconds for the plastic to cool down before pulling away. Try to avoid movement on the device to prevent damages. Be mindful that the more you heat up the staple, the longer the staple to cool down and the plastic to harden. 

Step 5: Pull PlastiWeld away from staple. It may also be helpful having a flat head driver to hold the staple in place as you pull away your device.

Step 6: You can either cut the staple edges or fold in the staple in.


Tip: You can strengthen the weld further by turning the staple 45* degrees during the insertion phrase when the staple is hot. By rotating the staple, more of the heated plastic will cover the staple, thus creating a stronger hold when the plastic cools down.

Avoid Overheating

When you overheat the staple and slowly press into the plastic, the plastic will liquify quickly, and it is possible that you may cause damage if your hands are not steady.


In addition, you will need to wait much longer to wait for the staple to cool down and let the plastic harden. Avoid this technique. Stick to the technique above.

Cut off or Fold in the ends of the staples

Using the provided clippers included in the kit, clip the ends of the staples so that they don't get in the way of any other objects. You can also fold in the staples.


From here, you're all set! Simply repeat the process every inch of the crack until you've completely welded the crack shut! 


Tip: You can further increase the weld's hold by heating up surrounding plastic surface to cover the staples in place. You may also use the ends of a soldering iron to heat up the plastic. If you are dealing with a plastic component that holds in plastic. It is recommended to solder the crack shut to prevent liquids from dripping out. 

Our Results: The Bend Test

We've stapled at every inch of the crack to securely hold the crack together. Here is our results from one of our staff using this tool on their own car! 

Does this truly work? Watch for yourself to find out! We used a good amount of force and it held up pretty well! Our staff is very excited to have fixed his own bumper!
