ISBM Molding-Filling-Sealing Line for PP IV Bottles
AIPAK Engineering ISBM molding-filling-sealing line produces polypropylene (PP) infusion bottles in one continuous process. PP granules are injection-molded into a preform with an integrated preform-and-neck-ring mold, heated and stretch-blown into a bottle by injection-stretch-blow-molding, then washed, filled and sealed on a washing-filling-sealing monoblock. The line runs under PLC control with CIP/SIP capability and is mainly used for conventional infusion, special infusion and flushing/irrigation solutions in 500 ml and 1,000 ml PP bottles.
Because forming and filling happen in-house on one line, the empty-bottle supply chain is eliminated, giving the lowest cost per finished bottle for large-volume and public-tender infusion markets.

ISBM Molding-Filling-Sealing Line Features:
- One-step process: injection molding → stretch blow molding → washing → filling → sealing, on a synchronized line.
- Integrated preform-and-neck-ring injection mold; high-cavity molds (e.g. 96-cavity for 500 ml, 64-cavity for 1,000 ml) for high output.
- Servo-controlled preform take-out robot and preform loading system for stable, high-speed transfer.
- Bottle washing by ion-air cleaning; the ion-air nozzle has alarm display and output.
- Filling adopts hard-pipe connection with time-pressure filling valves; supports CIP/SIP.
- Hot-melt sealing with closed cover delivery to prevent contamination.
- Full-process PLC control — no washing, no filling and no cap delivery without a bottle.
