The OD is increasing but have to be carful not to go over the limit. this is measured by filling the mould with water and then measuring the weight of the water. no polishing compound is used, the last step used a scotch brite type of wheel with oil. 120grit sand is put onto a cloth wheel with glue. up to 240 grit sand is used. The purpose of grinding is to remove CNC machine marks.
reminds me of this video of cleaning Tyre molds th-cam.com/video/1_cYaS-dyH4/w-d-xo.html . My brother works as a injection molding technician in a medical company.
Great work
I work in polishing bottle molds and repairing the copper neck of the molds. Can we exchange information?

I am a Polish artist in Iran. Can you share your experiences with me???🙏💗
Hi.. Im curious are polishing processes enlarge the OD of the glass bottle, even in 0.00mm? and what kind of compound paste that you use?
