I. Fundamental Differences Between the Two Types of Equipment‌

By 2025, the global stretch film rewinding machine market will reach 1.9 billion US dollars, with automatic models accounting for 67% of the market. The core differences are as follows:
Operating Method‌:

Manual models rely on manual tension adjustment, with skilled workers taking 8-12 minutes to change rolls
Automatic models are equipped with photoelectric alignment systems, enabling fully automated operation throughout the entire process

Precision control:

Manual models have a film roll hardness deviation of ±15%, while automatic models can control this within ±5%
Wintech automatic models use AI tension algorithms, with thickness fluctuations ≤0.02mm

Collaborative production: When connecting to a stretch film machine, the speed synchronization error of the automatic model must be <1.5%, otherwise it may cause film surface wrinkles.

II. Five-dimensional in-depth comparison

1. Cost-benefit analysis

Initial investment:

Manual basic model: £2,000–£4,000
Automatic standard model: ￥128,000–￥298,000

Long-term costs:

Wintech automatic models reduce labour costs per tonne of film by 82%
Waste film rate decreases from 5% for manual models to 1.2%

2. Production capacity adaptability

Manual model application scenarios:

Experimental production or daily output < 1 tonne
Flexible production with frequent switching between multiple specifications

Automatic model advantage scenarios:

Continuous production integrated with cast film extrusion line
Large-scale factories operating on a two-shift system with daily output of 5–20 tonnes
