Jwell is one of the few extrusion line manufacturers globally that designs and manufactures all three core components — screw & barrel, T-die, and polishing roller — in its own facilities. This vertical integration eliminates the dependency on third-party component suppliers that most extrusion line assemblers face, and it directly translates into three customer benefits:
Screw & Barrel: Manufactured in Jwell’s Zhoushan screw production base using nitrided steel with 950 HV surface hardness for the screw, and bimetallic Xaloy X-800 or equivalent alloy liners with 58-62 HRC for the barrel. The ABS-specific screw geometry features a carefully designed barrier flight with a 2.5:1 compression ratio and a 12 L/D gradual compression section that melts the SAN matrix while dispersing the polybutadiene rubber phase at controlled shear rates below 200 s⁻¹ — preserving impact strength that single-screw designs from component suppliers often degrade by 30-50%.
T-Die: Flexible-lip coat-hanger die manufactured in Jwell’s Changzhou die workshop, chrome-plated flow surfaces with mirror-finish polishing. The automatic die option uses individually controlled thermal bolts that respond to online thickness gauge feedback for closed-loop profile control — each bolt adjusts the die lip opening in real time based on measured sheet thickness at that position across the web.
Polishing Roller: 400 mm diameter rollers manufactured in Jwell’s roller workshop, chrome-plated base accepting interchangeable outer sleeves with surface finishes from Ra 0.025 μm (optical mirror) to custom-tooled embossing patterns. Temperature uniformity of ±1°C across the full face width, maintained by a closed-loop pressurized water circuit with independent roll temperature control.

Jwell’s ABS/HIPS refrigerator sheet line achieves a level of automation that reduces manual operation to supervisory oversight only. The automation chain covers the complete production sequence:
1. Automatic Unpacking & Material Loading: Raw material bags are automatically opened and conveyed to large storage silos (capacity matched to line throughput), with long-distance pneumatic conveying to the extruder hopper. This eliminates manual bag handling for lines consuming 2-3 tons of resin per hour.
2. Automatic Weighing & Blending: A gravimetric dosing system with automatic metal separation measures virgin ABS, HIPS, color masterbatch, and regrind in precise ratios (±0.5% batch accuracy), feeding the blend directly to the extruder throat. Recipe storage in the PLC enables one-touch changeover between different sheet formulations.
3. Automatic Thickness Control: An online thickness gauge (beta or X-ray) continuously measures the sheet profile across the web width, sending feedback signals to the automatic T-die’s individual thermal bolts. Each bolt adjusts the die lip opening to correct local thickness deviations in real time. Simultaneously, the servo-adjusted roll gap maintains overall sheet gauge with 0.01 mm precision.
4. Automatic Width Control — Edgeless Design: The line’s edgeless design eliminates the need for edge trimming, reducing material waste to near zero. Width adjustment is automated through the die width adjustment mechanism, synchronized with downstream equipment.
5. Automatic Stacking: Finished sheets are automatically counted, stacked to preset quantities, and conveyed to the packing station — eliminating the labor-intensive manual sheet handling that dominates conventional sheet extrusion operations.
This automation architecture aligns with Jwell’s Industry 4.0 initiative, enabling bus communication with factory MES/ERP systems for production scheduling, quality data logging, and OEE (Overall Equipment Effectiveness) tracking.

For refrigerator and appliance manufacturers consuming sheet by the ton per hour, Jwell offers a dedicated high-output configuration delivering 1,000-3,000 kg/h — throughput levels that place it among the highest-capacity ABS sheet extrusion systems globally. This configuration is purpose-built for the appliance industry’s production economics, where sheet cost per kilogram is the primary competitive metric and every percentage point of material utilization impacts the business case for in-house sheet production versus external purchase.
The high-output architecture scales the single-screw extruder to large diameters (120-200 mm depending on target output), paired with proportionally sized downstream equipment: wider die (up to 2,200 mm), larger-diameter polishing rolls, extended cooling sections, and automated stacking systems handling sheet dimensions up to 2,000 × 1,200 mm at production speeds. The extruder’s 33:1 L/D ratio and vented barrel design enable stable melt pumping at these throughputs without the melt fracture or surging issues that limit conventional extrusion lines above 800 kg/h.
This configuration has been validated across over 300 installations in refrigerator factories worldwide, with documented performance at Haier’s Hefei facility (16 lines), Midea’s Hefei facility (15 lines across经开区, 冷柜, and 零部件 divisions), and numerous other appliance manufacturing sites.

ABS sheet applications require radically different surface finishes, and Jwell’s roll stack accommodates all of them through a wide temperature operating range (40-120°C) and interchangeable roll surface sleeves. Automotive interior sheet needs a fine grain texture that hides fingerprints and resists scratching. Luggage sheet requires a glossy, scratch-resistant surface that accepts screen printing. Refrigerator liner sheet needs a smooth, easy-clean glossy finish.
The three 400 mm diameter chrome-plated polishing rolls accept quick-change outer sleeves with surface finishes spanning from Ra 0.025 μm optical mirror to custom-tooled embossing patterns matching automotive OEM grain specifications. Roll temperature uniformity of ±1°C across the full face width — maintained by individual closed-loop pressurized water circuits — eliminates the gloss variation bands that appear as visible stripes on textured ABS sheet when roll temperature is non-uniform, a quality defect that typically results in sheet rejection by automotive and appliance customers.
For converters switching between grain patterns or between glossy and textured surfaces, the sleeve changeover takes approximately 2-3 hours, with calibrated roll gap and temperature parameters stored in the PLC for each surface finish recipe.

ABS and HIPS sheet at 2.5-5.0 mm thickness forms refrigerator door liners, freezer compartment panels, and appliance housing components for the global white goods industry. This application is Jwell’s strongest market position — with over 300 lines delivered to the refrigerator industry and an estimated 90% share of China’s high-end extrusion plate equipment market.
Jwell’s refrigerator industry customer list includes:
– Haier Group: 55+ lines across合肥(16), 青岛(15), 胶州(10), 重庆(6), 贵州(3), 佛山(3), 沈阳(1), 大连(1), 武汉(1), plus Romania(2), Russia(2), India Noida(2), India Pune(1), Vietnam(1), Pakistan(1), Indonesia(1), Egypt(1)
– Midea Group: 39+ lines across合肥(15), 荆州(9), 广州(2), 佛山(2), plus Thailand Toshiba(6), Thailand Midea(2), Indonesia(3), Belarus(2), Algeria(1)
– Beko: 5 lines in Thailand, Russia, India, Pakistan, Turkey
– Samsung, LG, Whirlpool, Electrolux: Additional installations
The cooperation with Haier began in 2003 and spans over 20 years, reflecting the equipment reliability and after-sales support consistency that tier-1 appliance manufacturers require from their machinery suppliers.
ABS sheet for refrigeration applications demands chemical resistance to common household cleaners (foaming agents in polyurethane insulation have strong solvent effects), UL 94 HB flammability rating (with FR grades reaching V-0), and deep-draw thermoforming capability at moderate mold temperatures (100-130°C). Jwell lines serving this application typically include the full automation package: automatic material handling, thickness control, and sheet stacking.
ABS sheet at 2.0-4.0 mm thickness is thermoformed into door panel inserts, instrument panel components, center console trim, seat back panels, and interior pillar covers. Heat-resistant ABS grades (service temperature to 105°C) withstand the temperatures reached inside vehicles parked in summer sun without sagging or delamination.
For automotive OEMs, ABS with embossed grain texture delivers paint-free Class A surface quality — saving $2-4/m² in coating cost and the VOC emissions associated with painting processes. Jwell’s roll stack accommodates custom-tooled grain patterns that match OEM specifications for specific vehicle models, with interchangeable sleeves enabling rapid changeover between grain patterns for different production runs.
The consistent gauge profile from Jwell’s thickness automation system ensures uniform part weight in high-speed multi-cavity thermoforming tools producing 500-2,000 parts per shift. The PLC’s parameter logging infrastructure provides the complete production traceability that automotive quality audits require under ISO/TS 16949.
The dedicated ABS/HIPS refrigerator sheet extrusion line delivers 1,000-3,000 kg/h output, scalable through screw diameter (90-200 mm) and downstream equipment sizing. These high-output configurations have been validated across over 300 installations in refrigerator factories operated by Haier, Midea, Beko, Samsung, LG, Whirlpool, and Electrolux.
For converters entering the ABS sheet market or producing lower volumes, Jwell also offers a standard configuration at 300-600 kg/h suitable for automotive, luggage, and industrial sheet applications.
The line produces ABS sheet from 0.5 to 6.0 mm thickness, processing standard ABS, heat-resistant ABS (continuous service temperature to 105°C), flame-retardant ABS (UL 94 V-0 rated), HIPS (high-impact polystyrene), and multi-layer structures including ABS/PMMA and ABS/ASA for UV-resistant cap layers. Material changeover is managed through the Siemens PLC’s recipe storage with calibrated parameters for each material grade.
Jwell’s refrigerator-grade line uses a three-layer thickness automation system:
1. Online thickness gauge (beta or X-ray) continuously measures the sheet profile
2. Automatic T-die with individual thermal bolts adjusts die lip opening at each measurement position
3. Servo-adjusted roll gap maintains overall sheet gauge with 0.01 mm precision
This combined die + roll gap automation maintains thickness tolerance within ±1.5% across the full web width, verified by continuous thickness profiling during FAT.
ABS absorbs 0.3-0.5% moisture from ambient air and requires drying to below 0.05% moisture content before extrusion to prevent surface splay and molecular weight degradation. Jwell recommends a desiccant dryer with honeycomb rotor achieving -40°C dew point, 3-4 hours residence time at 80-90°C. The extruder’s vented barrel (33:1 L/D) with atmospheric vent in the decompression zone provides a secondary moisture removal safeguard. For the 3,000 kg/h refrigerator configuration, a 12,000-liter dryer capacity is recommended.
Yes. Jwell has over 20 years of overseas project experience covering installations in 120+ countries, including high-risk regions. The Global Engineer Certification System authorizes trained engineers worldwide to install, commission, and service Jwell extrusion equipment with full manufacturer warranty coverage. Nearly 50% of Jwell orders are exported.
