pressure and vacuum cycles

[everest_4]

Can someone please list all the steps of the pressure and vacuum cycle in detail. Starting from doing the first pressure to the last vacuum, I would appreciate that. I'm getting some pretty decent results but am not quite satisfied, so maybe there's something I'm missing. Thank-you

Hi Everest_4 What is the repair system you are using? Is is DK?

[everest_4]

Yes it's the newest DK injector and bridge.

With every break being different I would have thought pressure and vaccuum until the damage is full. There cannot be a specific number with so many variables, for me when I am sure it is full I give it one more cycle, always making sure to finish on a pressure cycle.

Leave the Injector in first pressure cycle for at least 5 minutes
Pressure cycles lasting for more than 5 minutes can be helpful
Use an UV shield to protect the area being repaired if necessary

After at least 5 minutes, place the injector into the first vacuum cycle
Hold the injector body top keep it against the glass
Lift up on the injector plunger head and rotate it 90 degrees clockwise and lock it in place
The first and all vacuum cycles should be 30 seconds long
Vacuum cycles lasting longer than 30 seconds are typically not necessary

After 30 seconds apply a second pressure cycle

Turn the injector plunger head 90 degrees clockwise and allow it to fall into place
Use two hands whenever the injector is moved from one position to another
One hand should hold the injector body in place
The second hand will control the injector head

Apply additional pressure to by pressing the plunger downward
Hold the injector in such a manner that the body does not put additional pressure on the glass.
Press the injector down until the seal is seen opening
The seal will also swell on the sides when under pressure
The injector head should never be within an 1/8” of the injector body
The second and all pressure cycles forward should be two to three minutes long
Again, additional time in the pressure cycle can be helpful

Alternate between pressure cycles of two to three minutes and vacuum cycles of thirty seconds until the repair looks complete and all air appears to be removed from the damage

Be sure to do at least 2 vacuum cycles per repair
Some repairs will take more cycles

I have been working on the marketing part of our business for the last month and a half and didn't do any repairs since my husband took over that part of the business. Now that we are over most of the "billing hurdles," I'm beginning to start repairing the chips. I found out that I needed a refresher course and went straight to the Windshield Repair Forum before doing any repairs. After perusing the different categories, I found Kgobin's GREAT video on repairing a star break and information on the pressure and vacuum cycles. I did my first two repairs yesterday and they turned out fantastic! My husband and I can only give Delta Kits, Inc., the highest recommendation for the wonderful training in April and the outstanding support while starting the business. Whenever we have a question, we know that we can always check the Windshield Repair Forum for additional information and call Eugene, Oregon for supplies as well.
