A 2 Cavity Semi PET Blow Machine offers a cost-effective, semi-automatic solution for PET bottle production via the stretch blow-molding process, featuring dual mould cavities to craft two bottles per cycle—where operators manually load infrared-heated preforms into the blowing station for precise axial stretching and high-pressure air expansion—delivering flexible outputs of 800–2,000 bottles per hour based on size and setup, ideal for bottles from 100ml to 5L in mineral water, beverages, edible oils, cosmetics, and pharmaceutical packaging. Renowned for affordability, low energy consumption, user-friendly pneumatic/electric controls, durable aluminum molds with quick-change designs, and reliable performance with minimal training required, these machines suit startups and small-scale operations, enhanced by safety interlocks, digital timers, and optional upgrades like auto-ejectors or preform heaters, ensuring consistent quality, reduced labor, and versatility for custom shapes while upholding food-grade standards like FDA compliance.
