Spiral Protective Sleeve Making Machine

The 38CrMoAlA nitrided screw and barrel pairing is engineered to deliver uniform melt quality across long production runs. This translates directly into consistent wall thickness and spiral geometry in the finished sleeve, reducing scrap and rework.

Cast aluminum barrel heaters paired with air cooling and electronic control instruments allow operators to fine-tune each heating zone independently. Accurate thermal management prevents material degradation and ensures repeatable product quality batch after batch.

The hardened gear reducer is built for uninterrupted duty cycles, supporting 24-hour production schedules common in high-volume sleeve manufacturing. Reduced gear wear means longer intervals between maintenance stops.

Extruder, forming die, cooling tank, tractor, cutter, and winder are configured as a single coordinated production line. This integrated layout reduces floor space requirements and simplifies line balancing, allowing a small crew to manage the entire process.

The automatic drying feeder removes moisture from raw resin before it enters the barrel, eliminating a common source of bubbles and surface defects. Operators spend less time on material preparation and more time on quality monitoring.
