内容（2-3段）:
The single-screw extruder employs a large-diameter, low-speed screw design philosophy specifically engineered for the high melt viscosity of HMW-HDPE and high-molecular-weight PP thick plate applications. Available in three diameters — Φ150 mm, Φ170 mm, and Φ180 mm — the screw is fabricated from 38CrMoAlA premium nitriding steel, a chromium-molybdenum-aluminum alloy that develops an exceptionally hard and wear-resistant nitrided case without the distortion associated with through-hardening.
The nitriding process produces a case depth of 0.5-0.7 mm with a surface hardness of HV≥940 and core hardness of HV≥740. This dual-hardness profile — an extremely hard, low-friction surface supported by a tough, ductile core — provides exceptional resistance to both abrasive wear from filler-containing compounds and adhesive wear from metal-to-metal contact in the compression zone. The 38:1 L/D ratio, combined with a barrier flight design and extended metering section, delivers the sustained high torque required to plasticize PE grades with melt flow indices as low as 0.05 g/10 min (190°C/2.16kg) and PP grades up to 40% mineral filler loading.
The large-diameter, low-speed approach reduces shear heating compared to smaller-diameter, high-speed alternatives, preserving the molecular weight distribution and mechanical properties of the polymer. This is particularly critical for HMW-HDPE thick plate where excessive shear-induced chain scission reduces environmental stress crack resistance (ESCR) and impact strength — the very properties that justify the material’s premium cost over commodity grades.

Positioned between the extruder discharge and the T-die, the positive-displacement gear pump eliminates the output pulsation inherent in single-screw extrusion, delivering constant volumetric melt flow regardless of screw speed fluctuations, material bulk density variations, or filter pressure build-up. This volumetric consistency — typically ±0.5% output variation — directly translates to sheet thickness uniformity across the full web width.
Jwell offers three melt pump options calibrated to the customer’s quality requirements and budget. The Jwell in-house pump provides cost-optimized performance with hardened gear teeth (HRC≥60) and oversized bearings for standard production environments. The Maag (Switzerland) pump, recognized as the industry benchmark for gear pump precision, delivers the tightest gauge control for customers serving specification-driven markets such as chemical tank lining where plate thickness tolerance directly affects weld quality and tank integrity. The Nordson (USA) pump is engineered for extreme-viscosity applications, with a robust bearing and seal design that maintains performance when processing UHMW-PE blends and high-filler-content PP formulations at elevated discharge pressures of 20-35 MPa.
Each pump is equipped with integrated pressure transducers and a dedicated temperature control circuit. The pump speed is synchronized with the main extruder screw speed and haul-off line speed through the Siemens PLC, creating a closed-loop cascade control that maintains constant die inlet pressure regardless of process disturbances upstream.

The T-die is fabricated from high-quality mold steel and undergoes a multi-stage surface finishing process: precision grinding, chrome plating, and mirror polishing to achieve cavity surface roughness of Ra 0.1µm and die lip roughness of Ra 0.05µm — near-optical surface quality. This ultralow surface roughness minimizes melt stagnation and polymer degradation at the die wall, a critical consideration when processing HDPE and PP with residence times that increase proportionally with thick-gauge throughput.
The die incorporates a flexible-lip design with independently adjustable lip gap segments across the full width, enabling fine-tuning of the transverse thickness profile. The heavy-gauge die body construction, with reinforced structural ribs and bolted end plates, limits total lip deflection to under 0.05 mm at maximum operating pressure — essential for maintaining gauge uniformity in 30 mm thick plate where even small die gap variations produce proportional thickness deviations downstream.
The chrome-plated flow channel provides two benefits beyond surface finish: corrosion resistance against acidic volatiles that may evolve from certain PP formulations, and a durable non-stick surface that simplifies die cleaning during material changeovers. The die is equipped with multi-zone cartridge heaters and integral cooling channels for precise temperature profiling across the width, with individual zone control maintaining ±1°C uniformity.

The three-roller vertical calendering stack forms the dimensional heart of the thick plate line. Each roller is forged from 42CrMo alloy steel — a chromium-molybdenum grade selected for its combination of high core strength, through-hardenability to HRC58-62, and dimensional stability under thermal cycling. Post-machining, each roller undergoes precision grinding achieving surface roughness Ra≤0.016µm, followed by hard chrome plating to a thickness of 0.08 mm for corrosion protection and extended service life.
Roller coaxiality is held to ≤0.005 mm across the full face width — a tolerance that eliminates the periodic thickness variation (gauge bands) produced by rollers with even minor eccentricity. Each roller is individually driven by an AC servo motor with closed-loop speed control, preventing inter-roller slippage that scratches the plate surface on chain-driven calibration stacks. The roller gap is set by a servo-driven hydraulic wedge mechanism with 0.01 mm positioning resolution and recipe-based gap recall from the HMI, enabling rapid thickness changeovers without manual gauge block insertion.
The roller temperature is controlled by a dedicated closed-loop pressurized water circuit with individual roller temperature regulation. For PE processing, roller temperatures are maintained at 60-85°C to manage the crystallization plateau at 115-120°C; for PP, the higher 100-130°C range supports the material’s elevated crystallization temperature. This roller-specific temperature flexibility is essential for a dual-material PE/PP line.

Custom tank fabricators weld PE and PP thick plates (8-20 mm) into secondary containment liners, stand-alone chemical storage tanks, and process vessel internals for aggressive media. HDPE’s ESCR rating of >1,000 hours (ASTM D1693, Condition B) prevents the environmental stress cracking that limits PP tank service life in the presence of surfactants, detergents, alcohols, and certain organic solvents. PP homopolymer, in contrast, provides superior temperature resistance (HDT up to 110°C) for acid and alkali storage at elevated temperatures where HDPE would soften.
The dual PE/PP capability of Jwell’s line enables tank fabricators to serve the full chemical compatibility spectrum from a single machine investment. When the application requires resistance to mixed chemical streams — a common scenario in industrial wastewater treatment, electroplating, and chemical transfer stations — HDPE provides the broad safety margin. When the application is pure acid or alkali storage within PP’s known compatibility window at elevated temperature, the line switches to PP production.
The mirror-polished T-die surface and precision roller stack produce plate with smooth, defect-free surfaces essential for reliable hot-gas and extrusion welding. Surface imperfections that trap air or contaminants during welding create leak paths in finished tanks. Jwell-produced plate weldability is validated through standardized bend tests and dye penetrant inspection at customer trial runs.
Commercial port operators and marina engineers specify PE thick plates (20-50 mm) for fender backing boards, bearing surfaces between steel fender panels and concrete dock walls, and lock gate wear strips. In this application, PE plate serves as a sacrificial wear element with a coefficient of friction against steel of 0.10-0.15 (dry) and 0.05-0.08 (wet) — values that reduce wear on both the polymer plate and the steel structure it protects.
The material properties that define PE’s marine performance are: complete resistance to saltwater and marine organism attachment, zero water absorption (<0.01%) ensuring no swelling or dimensional change after years of continuous immersion, UV-stabilized grades (2-3% carbon black loading) providing 20+ year outdoor durability without painting, and compressive strength of 18-22 MPa sufficient to distribute fender impact loads without permanent deformation. For PP thick plates in marine applications, the higher compressive strength of 25-35 MPa at 10% deformation and heat deflection temperature up to 110°C provide advantages in tropical port installations where ambient and radiant deck temperatures approach the softening point of PE.
The Jwell thick plate line’s ability to produce both PE and PP marine-grade plates from one machine enables manufacturers to serve port authorities who specify PE for temperate-climate installations and PP for tropical port environments — a common single-customer requirement for global port engineering firms.
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.
