Thank you for your kind reply with your glass finish specification (GFS) 28mm ROPP drawing as requested. Please find attached a set of GRP-0106 (Glass Finish Specification & Finish Cavity drawing for neck ring) for your kind reference.
We have reviewed on your existing neck ring drawing as compared to ACI’s finish cavity drawing for “A” dimension as follows:
GRP 0106 – BEAD “A” DIAMETER
The “A” diameter stated in your drawing is ideal size as compared to ACI’s drawing. Please confirm if your plant wishes to reduce the finish cavity on “A” diameter to 27.60 mm as per Toyo’s existing neck ring. At the same time, we wish to propose neck ring to include finish cooling fins for cooling application during forming operations. These cooling fins will avoid neck ring from running hot that may result finish ovality or oversized.
Our design team in OMCO Croatia will assist to provide our neck ring and guide plate drawings. We’ll submit to you for your approval soon. We look forward to your kind confirmation and reply soon. Thank you.
