Once you have cut a master laquer, you have metal stampers created and have records pressed from them. Discuss manufacturing here. (Record Matrix Electroforming- Plating, Vinyl Record Pressing.)

Curious why PVC is what we use and not some other hard, less toxic, plastic?? Any insight?

Quite a interesting question, but at this point i dont have a the right answer to it. Maybe the more experienced guys have it though.
Without starting a new topic:
At which point does PVC gets really toxic and what is a good way for a factory/operator to keep the work envoirement as healthy as possible? Savety is in my opinion in all cases the most important thing.
Have a good day,

It's cheap (compared to other plastics), low melting point therefore faster to mould, rigid, lasts forever, good wear resistance and able to fill the nooks and crannies of the groove with ease.
We used PVC from Australia, USA, Italy, Germany and China.
Only the American producti made by Keysor-Century Corp carried warnings that it was carcenogenic.
The Chinese product made by China Record Corporation would turn to charcoal and give off noxious fumes when overheated. You could feel the carcinogens filling your lungs and nasal passages. Just horrendous. This would only occur when fast-heating steam-heated extruders and not keeping an eye on the nozzle temperature.
Unless you burn the PVC and inhale the fumes, I can't imagine you are in any real danger.
