Founded in 1997, Jwell Machinery is one of China's largest plastic extrusion machinery manufacturers, with over 25 years of experience delivering reliable polycarbonate sheet production lines to customers in more than 100 countries. Every critical component — from screws and barrels to T-die heads and calender rollers — is designed and manufactured in-house, ensuring complete quality control from engineering drawing to final installation.
A polycarbonate sheet extrusion line is a complete production system that transforms raw PC resin pellets into flat polycarbonate sheets through a continuous melt-extrusion process. The system typically consists of a single-screw extruder, a precision T-die, a multi-roll calibration and cooling stack, a haul-off unit, a cutting system, and an automatic stacking unit.
Polycarbonate sheets produced by these lines offer exceptional impact resistance (250 times stronger than glass), high light transmission (up to 89%), excellent thermal stability, and built-in UV protection. These properties make PC sheets the material of choice for applications ranging from architectural glazing and greenhouse covering to automotive windshields and safety shields.
The JWS120 is designed for manufacturers producing standard-width polycarbonate sheets. With a sheet width capacity of 1,220 mm and thickness range of 2–10 mm, this model delivers 300–400 kg/h output. It is ideal for small to medium-scale PC sheet production facilities focused on solid sheets for building decoration, noise barriers, and greenhouse panels.
The JWS130 is Jwell’s flagship polycarbonate sheet extrusion line, capable of producing sheets up to 2,100 mm wide with the same 2–10 mm thickness range. With an output of 400–600 kg/h, the JWS130 is built for high-volume manufacturers serving large-scale construction projects, industrial roofing, and architectural curtain wall applications. A three-roll calibrator stack ensures precise thickness control and superior surface finish.

A standard polycarbonate sheet extrusion line produces between 300 and 600 kg/h, depending on the model and sheet specifications. Jwell’s JWS120 model outputs 300–400 kg/h for 1,220 mm width sheets, while the JWS130 model achieves 400–600 kg/h for sheets up to 2,100 mm wide. Production capacity varies based on sheet thickness, raw material grade, and line speed settings.
Most industrial polycarbonate sheet extrusion lines handle thicknesses from 2 mm to 10 mm for solid sheets. The Jwell JWS120 and JWS130 models both cover this 2–10 mm range. For thicker boards (above 10 mm), specialized sheet calibration systems with extended cooling stacks are required. Multiwall and corrugated PC sheet lines may have different thickness parameters depending on the rib structure and wall configuration.
The price of a polycarbonate sheet extrusion line depends on the model, sheet width, output capacity, and level of automation. A basic PC sheet line with 1,220 mm width capacity typically ranges from $80,000 to $150,000 USD, while a high-capacity 2,100 mm line like the JWS130 ranges from $150,000 to $300,000 USD. Jwell offers competitive pricing — typically 30% less than equivalent European brands — while maintaining comparable quality.

Polycarbonate sheet extrusion primarily uses virgin PC resin pellets, typically optical-grade Makrolon, Lexan, or equivalent grades with UV stabilizers. Some lines can also process PC regrind (recycled polycarbonate) blended with virgin resin at ratios up to 20–30%, depending on the required sheet clarity and mechanical properties. For co-extruded sheets with UV protection, a thin UV-resistant PC cap layer is extruded over the base material through a multi-layer T-die.
PC solid sheets are flat, monolithic sheets produced on a standard T-die extrusion line with a three-roll calibrator. Multiwall (hollow) PC sheets feature internal rib structures (2-wall, 3-wall, or X-structure) and require specialized extrusion dies with internal cavity formers, followed by a calibration vacuum system. Corrugated PC sheets have a wave-shaped profile and are produced using a corrugated forming roller stack instead of flat calender rolls. Each type requires different downstream equipment configurations.
After the equipment is shipped, installation and commissioning typically take 15–25 working days for a standard polycarbonate sheet extrusion line. This includes mechanical setup, electrical connection, cooling system installation, and process parameter optimization. Jwell provides on-site installation supervision and operator training as part of the delivery package. For turnkey projects including building infrastructure and utility preparation, the total project timeline is usually 3–6 months from order confirmation to full production.
Yes, a polycarbonate sheet extrusion line can produce both clear (transparent) and colored PC sheets. For solid-colored sheets, pre-compounded PC resin with color masterbatch is fed into the extruder. For co-extruded colored sheets, a thin colored PC layer is applied to one or both surfaces while maintaining a clear core. Common colors include bronze, opal white, blue, green, and solar grey. The line can switch between clear and colored production with a standard material changeover procedure taking 2–4 hours.
Single-screw extruders are the standard choice for polycarbonate sheet production because PC resin has good melt flow properties and does not require intensive compounding. Single-screw lines offer lower energy consumption, simpler maintenance, and higher output stability. Twin-screw extruders are used when on-line compounding is needed — for example, when blending PC with additives, fillers, or color masterbatches directly from raw materials without pre-compounding. Jwell offers both single-screw and twin-screw options depending on the customer’s raw material strategy.
Routine maintenance for a polycarbonate sheet extrusion line includes: weekly cleaning of the T-die lip surfaces, monthly inspection and greasing of gearbox and bearings, quarterly checking of screw and barrel wear, and semi-annual calibration of temperature controllers. The three-roll calibrator stack should have roller surface polishing checked annually. Jwell’s cloud-based remote monitoring system provides real-time alerts on machine health parameters. Critical spare parts such as heater bands, thermocouples, and filter screens should be kept on site. Regular screw pull inspections are recommended every 6–12 months depending on operating hours.
Choosing the right PC sheet extrusion line depends on five key factors:
(1) Target products — solid sheets, multiwall sheets, or corrugated sheets;
(2) Sheet dimensions — required width (1,220 mm vs. 2,100 mm) and thickness range (2–10 mm standard, or custom);
(3) Production capacity — daily or monthly output volume targets;
(4) Raw material strategy — virgin resin only or blending with regrind;
(5) Budget and automation level — manual, semi-auto, or fully automatic stacking and packaging. Contact Jwell’s application engineers with your requirements for a free consultation and customized line configuration.
