Hi,
At our company, we mold plastics containers. We also make our molds as we have our own tooling shop.
Now we have one of our mold that is used, it have 10 years of production, many millions bottles made... We have bought a flame metallizing gun in the past that we've never used. I decide to give it a try to repair the mold and remachining it. As the mold only tend to flash at a precise location in the mold, I don't have to rebuild the complete cavity. Now I got 2 cavity rebuild with this process and I must say it does the job so well!!
We have ever tryed to rebuild a cavity with TIG welding but it always leave welding marks which is reflected on the plastics product.
So I'm here asking for some more informations, comparaison on both welding method. Ok... metalizing it's not really welding but hey, you understand what I mean.
My first questions would be : does anyone use metallizing and for what? And why metallizing seam to not be popular in mold repair process?
I would try to take pics to show the before and after of a rebuild cavity.
