A PU encapsulated wire rope screen is a screening medium in which steel or stainless-steel wire rope is covered or integrated with polyurethane. The wire provides structural reinforcement; the polyurethane forms the material-contact surface. Tufflex-type screens may also use polyurethane-covered synthetic cord as part of the construction. The composite is designed as replacement media for conventional hooked-edge woven wire screens.

Working Principle

The wire rope provides tensile strength and structural integrity between the hooked edges. The polyurethane coating protects the reinforcement from abrasion and creates a smooth material-contact surface. In wet or sticky duty, this smooth surface reduces material adhesion and buildup compared with exposed wire mesh.

The synthetic cord, where present, influences material flow and stratification depending on screen configuration. Because the wire rope, PU covering, welded structure, and aperture geometry interact, the screen cannot be specified by aperture alone.

Benefits

Wear resistance. PU protects the reinforcing wire from direct abrasion by the material.

Flexibility. Composite construction allows the screen to flex during vibration, reducing pegging.

Reduced material buildup. The smooth PU surface resists adhesion in wet and sticky duty.

Structural integrity. Wire rope provides strength where exposed wire mesh would deform.

Replacement compatibility. Hooked-edge configurations are designed to be tensioned like conventional screening media.

Customization. Dimensions, apertures, hook configurations, and PU formulations can be produced to drawing.

Applications

PU encapsulated wire rope screens are applied where operators face abrasion, wet feed, sticky materials, pegging, or blinding. They are particularly relevant where conventional WIRED & STEEL SCREEN MESH blinds or wears rapidly.

They are not automatically the correct choice for every application. Dry, extremely coarse, high-impact duty may require different media. Very fine screening may require specialised polyurethane fine-screen technology rather than a conventional wire-rope screen.

Screening sits between CRUSHING and GRINDING in the comminution circuit.

Selection Guide

Six inputs determine the correct specification:

1. Wire-rope diameter — must provide sufficient strength while remaining compatible with the required aperture.

2. Aperture shape and size — square and rectangular openings suit different screening requirements; aperture accuracy matters most in fine separation.

3. PU covering — formulation determines abrasion resistance, elasticity, and surface smoothness.

4. Hook and tensioning system — side or end tension, hook dimensions, material, position, panel dimensions, and supporting profile arrangement.

5. Screen machine — model, deck dimensions, and existing tensioning system must be confirmed.

6. Feed conditions — material type, moisture, stickiness, abrasiveness, feed size, and required capacity.

Procurement Guide

Required information: screen machine model, screen type (side/end tension), panel size, aperture shape, aperture size, existing wire-rope diameter if known, material type, feed condition, maximum feed size, capacity, and required quantity.

Drawings needed: existing screen drawing, photograph, or panel sample. If wire-rope diameter or hook dimensions are unknown, send photos — an experienced manufacturer can identify which dimensions need confirming.

Material selection: request PU formulation and hardness data, wire rope material (steel or stainless), and cord specification where applicable.

MOQ: typically per panel or per deck set.

Lead time: commonly 2–4 weeks for standard configurations; longer for custom drawings.

Packaging: crated flat to prevent deformation of hooks and wire geometry.

Shipping method: sea freight for volume; air freight for breakdown-critical replacement.
