PET Zipper Monofilament Extrusion Machine | NLY Machinery
Overview
The PET zipper monofilament extrusion and drawing machine from NLY Machinery is designed for the stable production of monofilaments used in zipper manufacturing. The extrusion line supports both virgin PET granules and recycled PET bottle flakes, allowing manufacturers to flexibly balance product appearance, performance stability, material cost, and sustainability requirements.
Raw Material Compatibility: Virgin PET & Recycled Bottle Flakes
NLY Machinery’s PET zipper monofilament extrusion line is engineered to process different PET raw materials with reliable performance. Virgin PET granules are typically selected for zipper monofilaments requiring clean appearance and consistent surface quality, while recycled PET bottle flakes are increasingly used to reduce material costs and support sustainable manufacturing. The equipment ensures stable processing for both material types.
Differentiated Melt Filtration & Process Stability
To address the processing differences between virgin PET and recycled PET bottle flakes, NLY Machinery equips the extrusion system with dedicated melt filtration solutions. Standard fine filtration is applied for virgin PET materials, while recycled PET bottle flakes are processed through enhanced multi-stage melt filtration systems to effectively remove impurities. This design helps maintain stable filament diameter, uniform surface quality, and reliable mechanical performance during continuous production.
Flexible Winding Options & Market Recognition
The PET zipper monofilament extrusion line from NLY Machinery supports 15 kg and 80 kg winding packages, meeting the needs of different customers and downstream production processes. NLY Machinery’s monofilament extrusion machines hold a strong position in the Chinese domestic market and are widely recognized by zipper manufacturers. Internationally, especially in India, the equipment is well regarded for stable operation, adaptability to local raw materials, and suitability for long-term industrial production.
