Why choose manual screen changer

Summary in one sentence: Clean materials, low output, low frequency of screen replacement, limited budget, small on-site space, do not want complex maintenance, prioritize manual screen replacement.

1. Low procurement cost and highest cost-effectiveness

For the same specifications, the price is generally only 1/3 to 1/5 of that of hydraulic screen changers and 1/5 to 1/10 of that of continuous screen changers. With low initial investment pressure, it is suitable for small factories, start-up production lines, experimental lines, and small extruders.

2. Minimalist structure with extremely low failure rate

There is no hydraulic station, oil cylinder, oil pipe, solenoid valve, PLC electronic control, and almost no easily damaged power components; The body is nitrided and wear-resistant, and can be used normally for 8-10 years. It rarely leaks oil, gets stuck in valves, or experiences circuit failures, and the pressure on workshop electricians is low.

3. Extremely low maintenance costs

Usually, only regular replacement of the filter screen and a small amount of sealing components are needed; Without hydraulic oil replacement, cylinder sealing maintenance, and circuit inspection, the maintenance cost throughout the entire lifecycle is very low.

4. Easy to operate and quick to get started

Workers can operate it in just a few minutes with simple training, without the need to understand hydraulic or electrical systems; Power outages and unstable gas sources in the workshop do not affect usage, and have low requirements for supporting conditions.

5. Compact size and small footprint

Without a hydraulic station, the flange is directly connected to the extruder/melt pump, suitable for scenarios where the machine position is compact and old equipment is retrofitted. It is easy to install and compatible with extruders with 30-200mm screws.

6. Suitable working conditions (emphasis, for customer selection)

Clean raw materials (new materials, natural materials, less impurities)

The interval between network changes is long, such as several hours or even a day

Small and medium-sized production capacity: small blown film, small pipe, small granulation, laboratory/sample extrusion line

The product allows for brief downtime and network replacement, and does not require 24-hour uninterrupted stable production
