Engineered to withstand up to 350 bar operational pressure and 340°C thermal conditions in demanding polymer processing lines across Poland.
Understanding the strategic importance of high-performance screen mesh and polymer candle filtration across Polish manufacturing hubs.
Poland has emerged as a premier plastic processing and packaging powerhouse within the European Union. Crucial industrial zones—including the Silesian Industrial Region (Katowice, Gliwice), Greater Poland (Poznań), Lower Silesia (Wrocław), and the Central Corridor (Łódź)—house sophisticated extrusion facilities. These plants require continuous screen changers and high-capacity candle filter assemblies to maintain high-throughput extrusion of blown film, cast film, sheet profiles, and automotive polymer components.
Under strict EU Packaging and Packaging Waste Regulations (PPWR) enforced across Polish domestic markets, processors must integrate up to 30-50% post-consumer recycled (PCR) resin. Processing PCR polymers introduces challenging contaminants—such as cross-linked gels, aluminum dust, wood fibers, and residual adhesives. Utilizing premium stainless steel wire mesh filter discs and multi-layer continuous screen belts ensures flawless melt purity without causing frequent melt pump fluctuations or machine down-time.
A detailed technical evaluation of wire mesh geometries and multi-layered sintered structures designed for critical polymer melt conditions.
Characterized by a coarse warp wire density and a fine weft wire structure. Delivers high mechanical strength and stable aperture geometry. Ideal for coarse extrusion screening, pre-filtration in pelletizing lines, and primary protection against metallic contaminants.
Rating: 80μm - 300μmWeft wires cross over and under two warp wires, producing a dense mesh matrix with smooth surface characteristics. Exceptionally suitable for fine particle capture, gel separation, and high-pressure polymer melt spinning applications.
Rating: 15μm - 80μmEngineered specifically for continuous auto-belt screen changers (e.g., automated hydraulic screen changers). Warp wires feature ultra-high tensile strength to withstand axial pull forces without elongation or rupture under continuous melt flow.

Customized engineering frameworks designed to optimize melt homogeneity, stabilize back-pressure, and eliminate pinhole defects.
Processing heavily contaminated agricultural films or post-consumer rigid packaging causes rapid clogging of standard screens. Our multi-layer spot-welded mesh packs combined with automated continuous reverse dutch mesh belts allow continuous backwashing, extending filter change intervals by up to 300%.
Ultra-thin packaging films require zero gel tolerance and microscopic dirt retention. We supply vacuum-sintered stainless steel fiber felt candle filter elements that deliver low initial differential pressure, high dirt-holding capacity, and extended on-stream service life.
For Polish nonwoven fabric manufacturers producing hygiene and medical garments, filament breakages cause catastrophic line stoppages. Our custom-engineered 316L candle cartridges feature uniform pore size distribution, guaranteeing stable polymer delivery to the spinneret.
Aligning next-generation metallurgical advancements with Polish industrial sustainability targets.
Modern extrusion lines are rapidly integrating real-time pressure sensor arrays prior to and following screen changers. By pairing our low-tolerance stainless steel filter elements with dynamic predictive maintenance algorithms, plant operators in Poland can automatically trigger belt advancement or backwash cycles at precise pressure thresholds, minimizing material waste.
To prevent thermal degradation and polymer carbonization during prolonged high-temperature filtration of engineering plastics (e.g., PEEK, PET, PA66), our research leads the industry in applying chemical vapor deposition (CVD) coatings and plasma nitriding. These treatments reduce polymer melt adhesion to screen wires, facilitating effortless ultrasonic cleaning.
