JWS150+JWS90 HIPS/ABS Sheet Extrusion Line Commissioned in Algeria — June 2026

The JWS150+JWS90 HIPS/ABS sheet extrusion line is a twin-extruder co-extrusion system designed by Jwell Machinery for high-output production of HIPS (High Impact Polystyrene) and ABS (Acrylonitrile Butadiene Styrene) sheets. It combines a JWS150 single-screw main extruder with a JWS90 co-extruder to deliver 1,200 kg/h output across a 2,100 mm production width, covering thicknesses from 0.5 mm to 8 mm — making it one of the most versatile wide-width sheet lines deployed in North Africa as of mid-2026.

1. Project Overview: Commissioning and Timeline

The project timeline followed Jwell’s standardized turnkey delivery model: equipment manufacturing and pre-delivery inspection at Jwell’s Shanghai production base, containerized sea freight to Algeria, on-site mechanical installation by Jwell’s field-service engineers, electrical commissioning, and a 72-hour continuous trial production run. All milestones were met on time, and the line transitioned directly into commercial production with no post-commissioning downtime.

Project snapshot:

• Commissioning date: June 2026
• Location: Algeria, North Africa
• Machine model: JWS150 + JWS90 co-extrusion system
• Products: HIPS sheets, ABS sheets (plain, embossed, co-extruded multi-layer)
• End-use: Refrigerator inner liners, home appliance housing, advertising signage

2. Customer Challenges: Scaling High-Precision Sheet Production in North Africa

The customer operates one of Algeria’s largest appliance manufacturing facilities, producing refrigerators, washing machines, and air-conditioner units for both domestic consumption and export across the Maghreb region. Three specific challenges drove the investment decision:

1. Output stability at scale. The customer required a proven system delivering at least 1,000 kg/h without fluctuations that cause thickness variation — critical for vacuum-formed refrigerator liners where ±0.05 mm tolerance is non-negotiable.
2. Material flexibility. The line had to switch between HIPS and ABS formulations within a single shift, accommodating multi-product production schedules without extended changeover downtime.
3. Wide-width capability. With appliance door panels and interior liners requiring sheets up to 2,100 mm, the extruder and downstream equipment had to maintain uniform melt distribution across the full die width.

3. Line Advantages: How the JWS150+JWS90 Configuration Delivers

3.1 JWS150 Main Extruder: High-Output Single-Screw Technology

The JWS150 single-screw extruder is purpose-built for high-throughput sheet production. Its 150 mm screw diameter and 38:1 L/D ratio provide extended residence time for complete plastication of HIPS and ABS resins, while the barrier screw design eliminates unmelted particle carryover at high screw speeds. Key specifications:

• Screw diameter: 150 mm | L/D ratio: 38:1
• Barrier-type screw with dedicated mixing section for HIPS/ABS formulations
• AC vector inverter drive with 0.01 rpm speed resolution for precise output control
• Ceramic band heaters with PID multi-zone temperature control (±1°C accuracy)

3.2 JWS90 Co-Extruder: Multi-Layer Capability

The JWS90 co-extruder enables production of ABA-structure co-extruded sheets — a high-gloss virgin ABS cap layer over a recycled or lower-cost core — reducing raw material cost by up to 30% while maintaining Class-A surface finish on both sides. The co-extrusion feedblock and multi-manifold die ensure consistent layer thickness ratios across the full 2,100 mm width.

3.3 Downstream Equipment: Precision Calibration and Winding

The downstream system features a three-roll vertical polishing stack with individually driven rollers, each with 0.01°C-resolution oil temperature control. The precision gap adjustment system maintains sheet thickness uniformity to within ±0.05 mm at 2,100 mm width — a tolerance envelope that meets automotive interior trim and premium appliance panel standards.

5. Applications: What the Line Produces

5.1 Refrigerator Inner Liners

HIPS sheets produced on this line are vacuum-formed into refrigerator and freezer inner liners. The line’s ±0.05 mm thickness tolerance ensures uniform wall thickness in deep-draw forming, eliminating thin spots that compromise insulation performance and structural integrity.

5.2 Home Appliance Panels

ABS sheets with high-gloss or matte-embossed surface finishes serve as exterior panels for washing machines, air conditioners, and small kitchen appliances. The co-extruded ABA structure enables a premium virgin-ABS cap layer over a cost-optimized core, reducing per-unit material cost without sacrificing surface quality.

5.3 Advertising Signage and Displays

Both HIPS and ABS sheets are thermoformed into point-of-sale displays, exhibition booth panels, and outdoor signage. The wide 2,100 mm format reduces post-production joining and maximizes material yield for large-format applications.

5.4 Automotive Interior Components

ABS sheets with textured or embossed surfaces supply the automotive interior trim supply chain for door panels, dashboard inserts, and seat-back covers — applications where consistent thickness and surface finish directly affect downstream forming yield.

6. Strategic Significance: Jwell’s North Africa Milestone

Prior to this project, Jwell’s sheet extrusion references were concentrated in China, Southeast Asia, the Middle East, and Eastern Europe. The Algeria commissioning demonstrates that Jwell’s turnkey delivery model — including on-site installation, commissioning, and operator training — functions effectively in African logistics environments with extended sea-freight lead times and limited local technical infrastructure.

The project also aligns with Algeria’s import-substitution industrialization policy: by enabling local production of appliance-grade plastic sheets, the customer reduces reliance on imported semi-finished materials, shortens supply chains, and gains cost competitiveness in both domestic and regional export markets.
