Note:
The above specifications are subject to change without prior notice. Actual production capacity may vary depending on material properties, product dimensions and processing conditions.
PP/PE thick plates are used to fabricate chemical storage tanks and corrosion-resistant containers, offering excellent chemical resistance and reliable performance in industrial environments.
Suitable grades of PP and PE plates are used in food processing equipment, storage containers, processing tanks and protective components. Their moisture resistance, corrosion resistance and easy-to-clean surfaces support hygienic industrial processing applications.
HDPE thick plates are commonly used for ice rink dasher boards and protective barriers. Their excellent impact resistance, toughness and low-temperature performance make them suitable for demanding ice sports environments.
Specially formulated antistatic PP/PE sheets can be used for industrial protective panels, equipment covers and electronic manufacturing environments requiring static control.
The three models scale by screw diameter and motor power:
Selection guidance: if your current annual plate demand is below 3,000 tonnes, the JWPE-150 provides adequate capacity. For 3,000-5,000 tonnes, the JWPE-170 balances investment against throughput. Above 5,000 tonnes, the JWPE-180 maximizes revenue per square meter of factory floor space. All models share identical downstream equipment — you can start with a JWPE-150 and upgrade to a larger extruder later without replacing the entire line.
Yes, the line processes HDPE, HMW-HDPE, UHMW-PE blends, PP homopolymer, and PP copolymer. Material changeover uses recipe-based PLC presets controlling barrel temperature profiles, screw speed ranges, melt pump settings, roller temperatures, and haul-off speed. The complete PE-to-PP transition requires approximately 2-3 hours:
1. Purging the extruder and melt pump with PP-compatible purging compound (~60-90 min)
2. Switching screen packs in the hydraulic screen changer (~20 min)
3. Adjusting roller temperatures — PE typically runs at 60-85°C, PP at 100-130°C (~45-60 min)
4. Recalibrating haul-off tension and cutter settings (~15 min)
The PLC stores up to 20 recipe presets, so once both PE and PP recipes are saved, subsequent changeovers require approximately 2 hours. Jwell engineers provide on-site training for the complete changeover protocol during commissioning.
The selection depends on your target market and quality requirements:
– Jwell in-house pump: Suitable for standard industrial plate applications (construction formwork, temporary protection plates, general fabrication) where cost optimization is the primary driver. Provides adequate ±0.5% volumetric consistency for most applications.
– Maag (Switzerland): Recommended for specification-driven markets where gauge tolerance directly affects customer acceptance — chemical tank lining (weld quality depends on thickness uniformity), food processing plate (uniform heating in thermoforming equipment), and marine fendering (load distribution uniformity).
– Nordson (USA): Recommended for processors running high percentages of recycled content or high-filler formulations that generate elevated melt pump discharge pressures. The robust bearing and seal design extends service intervals under demanding conditions.
The 38CrMoAlA nitrided screw with HV≥940 surface hardness typically achieves 18,000-24,000 operating hours before requiring re-nitriding or replacement, depending on feedstock characteristics:
– Virgin HDPE/PP production with minimal filler: 22,000-24,000 hours
– Production with up to 20% recycled content: 18,000-22,000 hours
– Production with 30-40% mineral filler (PP): 15,000-18,000 hours
The screw is designed for re-nitriding — the 0.5-0.7 mm case depth allows one re-nitriding cycle before the screw diameter falls below service tolerance. Jwell supplies a complete screw maintenance manual with wear measurement procedures and re-nitriding specifications. A spare screw is recommended for operations running above 7,000 annual hours to eliminate production downtime during screw maintenance.
Installation and commissioning follows this schedule:
– Site preparation (customer responsibility): Reinforced concrete foundation per Jwell’s layout drawing (C25/30, ≥200 mm thickness), utility connections (power, cooling water 25-40 m³/h, compressed air 0.6-0.8 MPa), overhead crane ≥5-ton capacity, appropriate factory clearance for 35-45 m line length
– Mechanical installation (Jwell engineers + customer team): 7-10 working days
– Electrical installation and wiring: 3-5 working days
– Cold commissioning (no material): 1-2 working days
– Hot commissioning (production trial with customer’s materials): 3-5 working days
– Operator training: Integrated during hot commissioning, approximately 20 hours total
Jwell provides 1-2 factory-trained engineers on-site for the full duration. Customers should allocate 2-3 mechanical technicians and 1-2 electrical technicians to work alongside Jwell engineers for knowledge transfer.
The line’s total weight of 35-50 tonnes distributed over 35-45 meters creates approximately 1-1.5 tonnes per linear meter of floor loading — typical for heavy extrusion equipment and within the capacity of standard industrial building floor slabs meeting the C25/30, 200 mm specification.
