Request a QuoteWe are a professional injection mould manufacturer
specializing in PET preform and cap moulds with over 10 years of
experience. Our PCO 1881 mineral water cap mould is designed to produce
high-quality 30/25mm screw caps that fully comply with international PCO
1881 standards, ensuring perfect sealing performance and compatibility
with standard PET bottle necks.
PCO 1881 Standard Compliance: Precision-engineered to meet strict PCO 1881 neck finish specifications, guaranteeing leak-proof sealing and smooth capping on automatic filling lines.
High Cavity Configuration: Available in 32, 48, and 72 cavities to meet different production capacity requirements. High-speed injection molding with cycle times as fast as 3.5-4.5 seconds.
Advanced Hot Runner System: Equipped with high-performance hot runner and temperature control system to ensure uniform filling, reducing material waste and improving product consistency.
Durable Material & Long Service Life: Made from high-grade tool steel (e.g., S136, 2316) with anti-corrosion treatment, ensuring a service life of over 5 million shots.
Precision Core & Cavity: CNC machined and EDM processed for high dimensional accuracy, ensuring each cap fits perfectly with the bottle neck for reliable sealing.
Automatic Stripping Design: Integrated automatic stripping mechanism for stable and efficient production, minimizing manual intervention and downtime.
