OEM Woven Wire Cloth Mesh Manufacturer & Precision Melt Filtration Engineering

Micro-Geometric Topology & Flow Dynamics

Woven wire cloth mesh forms the indispensable rheological backbone in continuous polymer extrusion, compounding, and chemical fiber spinning plants worldwide. Unlike conventional depth filters or fibrous nonwoven matrices, metal wire cloth provides absolute pore geometric stability under extreme operational parameters: temperatures exceeding 350°C and hydrodynamic pressures beyond 300 bar.

In modern high-capacity extrusion lines, the microscopic architecture of wire mesh—ranging from plain and twill weaves to reverse Dutch weaves—dictates fluid boundary layer resistance, shear degradation, and laminar flow stability. As global polymer processors integrate circular economy resins (PCR/PIR) with erratic melt indexes, the filtration screen is no longer merely a consumable part; it serves as a critical process stabilization element that governs final tensile integrity and optical transparency.

• Strictly controlled pore size distribution mitigating mechanical polymer chain scission.
• Optimized shear stress profile across breaker plates for uniform residence distribution.
• Zero wire-migration thresholds ensured by state-of-the-art laser perimeter slitting.

Plastic Extrusion & Compounding Lines

In standard extrusion and masterbatch compounding, woven wire screen packs are situated directly against the breaker plate. Their dual function is to capture unplasticized resin granules and create sufficient backpressure for plasticizing homogenization.

HG provides multi-layer spot-welded and rimmed disc packs (20 to 500 mesh). By layering coarse support mesh with calibrated Dutch filter cloth, our assemblies resist differential blow-outs under high shear conditions while extending production longevity.

BOPET, BOPP & Optical Film Manufacturing

Biaxially oriented film lines cannot tolerate fish-eyes, cross-direction thickness variance, or micro-gels. A single sub-visible particulate can rupture the film web during high-speed longitudinal and transverse orientation.

HG leaf disc filters feature multi-layer sintered wire cloth and specialized drainage hubs that provide exceptional filtration area in a compact footprint. Discs maintain uniform radial flow distribution, eliminate melt stagnation, and minimize thermal degradation.

Chemical & Synthetic Fiber Spinning (POY/FDY/Spunbond)

Continuous synthetic fiber production relies on candle filter elements to shield delicate spinneret micro-orifices from abrasive particles and char buildup. Any premature clogging leads to filament breakages, yarn denier irregularity, and downtime.

Utilizing cylindrical and pleated sintered metal fiber felt alongside high-precision woven wire mesh, HG candle elements achieve high void volume (up to 85%), delivering extraordinary dirt-holding capacity and low initial differential pressure drop.

Closed-Loop Recycling & Pelletizing Machinery

Filtration efficiency in post-consumer plastic recycling depends directly on upfront shredding, washing, and friction drying. Contaminated feedstocks—such as PP agricultural film, woven sacks, and bottle flakes—require rugged processing equipment.

HG manufactures both the downstream melt filtration systems and the complete turnkey recycling lines (crushing, washing tanks, hot drying, and granulating). This cohesive integration guarantees reliable pellet cleanliness and operational efficiency from raw scrap to finished resin.
