Plastic and rubber extrusion experts are surely familiar with the single-plate hydraulic screen changer! Its rapid screen changes and compact size are all thanks to its brilliant structural design. Today, we'll dissect its core structural features—read on to understand why it's so effective!

Four Core Structural Features, Each Highly Practical!

Single-Plate Screen Design for Ultra-Streamlined Screen Changes

The core is a single sliding plate with the screen attached! Unlike dual-plate machines that switch between two plates, it fixes the screen directly onto a single sliding plate. This makes the structure more compact and smaller in size, requiring minimal installation space and easily adapting to small production lines.

Hydraulic drive system ensures stable and rapid switching

A hydraulic cylinder propels the slide plate! Compared to manual screen changes, hydraulic power delivers smoother, stutter-free movement. Screen replacement completes within 3 seconds, with precise speed control via hydraulic valves preventing material leakage from screen displacement.

Precision-machined sealing surfaces ensure leak prevention

The pump body and slide plate sealing surfaces undergo mirror polishing, paired with high-temperature resistant seals for exceptional fit. Even when conveying high-temperature, high-viscosity melts (e.g., PE, PVC), it maintains a tight seal with virtually no melt leakage, ensuring a cleaner production environment.

Short, smooth flow paths minimize melt resistance

Internal flow channels are designed to be compact and streamlined, eliminating unnecessary bends! Melt experiences minimal resistance from entry to exit, preventing stagnation or degradation caused by complex pathways. This makes it ideal for extrusion applications demanding high melt quality, ensuring consistent product performance.

Why do established factories love it?

Simple structure means easy maintenance! No complex disassembly required for screen changes—just open the cover plate to replace the screen on the slide plate. Even beginners can handle it. Plus, it costs less than dual-plate screen changers, making it a cost-effective choice for small to medium production runs.

Whether for pipe extrusion or film production, it effortlessly handles screen change needs! This design truly understands the pain points of plastic manufacturing.
