Plastic Drum Mould Manufacturers in Kolkata
Unique Mould supplies precision-built plastic drum moulds in Kolkata for blow moulding and injection applications. Our moulds are engineered for high output, consistent wall thickness, and long service life—ideal for water, chemical, edible oil, and packaging drums from 20L to 250L. With CNC machining, superior steels, and rigorous QC, we deliver fast cycle times, smooth demoulding, and minimal maintenance for your production lines.
Working Principle of Plastic Drum Moulds
In blow moulding, heated polymer parison is inflated inside a precision cavity to form a hollow drum. Our moulds—built with hardened inserts, cooling channels, and balanced venting—control thickness, ring stiffness, and barrel geometry for maximum strength. For components like lids and bungs, injection moulds ensure accurate fit and leak-proof closures. Explore our manufacturing capabilities for high-volume Kolkata and pan-India projects.
