What are the main differences between PC sheets, PMMA (acrylic), and glass?

Three materials serve different purposes: PC Sheet excels in impact strength (250x glass), flexibility, and temperature range (-40C to +120C), making it ideal for safety-critical applications like bulletproof glazing and windshields. PMMA/Acrylic offers superior surface hardness (resists scratching better), higher gloss (~92% light transmission), and better UV weatherability at lower cost, suited for signage and display. Glass provides absolute scratch resistance and chemical inertness but is heavy, brittle, and difficult to transport/install. For industrial sheet production, PC strikes the best balance between durability, processability, and cost-performance ratio.

What production capacity and sheet specifications can Jwell PC extrusion lines achieve?

Jwell offers two primary models: JWS130/38-2200 produces sheets up to 2,100 mm wide, 2-10 mm thick, at approximately 550 kg/h output. JWS120/38-1400 handles widths up to 1,300 mm, thickness 1.5-10 mm, at around 450 kg/h. Both feature precision T-dies, three-roll calender stacks with independent temperature control per roll, and Siemens PLC + ABB inverter automation. Production speed typically ranges from 1-5 m/min depending on sheet thickness. Custom configurations available upon request.

What key factors should I consider when choosing a PC sheet extrusion machine?

When selecting a PC sheet extrusion line, evaluate these critical factors: (1) Output Capacity — match hourly output (kg/h) to market demand; (2) Sheet Width and Thickness Range — ensure die and calender cover your product portfolio; (3) Screw Design — PC requires gentle, uniform melting without degradation; look for specialized barrier screws or twin-screw options; (4) Temperature Control Precision — multi-zone PID control is essential as PC is sensitive to thermal history; (5) Die Technology — coat-hanger T-die with automatic lip adjustment ensures consistent gauge; (6) Automation Level — PLC control reduces operator dependency and improves consistency; (7) After-Sales Support — spare parts availability, technical training, and remote diagnostics capability are crucial. Jwell addresses all seven with in-house manufactured core components including barrels, screws, dies, and rollers.

What is the delivery timeline for a Jwell PC sheet extrusion line?

Typical lead time is 60-90 days from order confirmation to ex-factory readiness. Ocean freight: 25-35 days to North America, 20-30 days to Europe, 7-15 days to Southeast Asia. On-site installation by Jwell engineers takes 15-25 days, including mechanical alignment, electrical integration, process tuning, and operator training. Total project timeline from order to production-ready is typically 3-4 months. Rush orders may be accommodated with expedited scheduling surcharges. We recommend placing orders 3-4 months ahead of your planned production start date.

What common issues occur during PC sheet production and how to resolve them?

Five key issues and solutions: (1) Bubbles/Voids — caused by moisture (PC is highly hygroscopic); pre-dry resin at 120C for 3-4 hours using a dehumidifying dryer before extrusion. Target moisture below 0.02%. (2) Yellowing/Discoloration — thermal degradation from excessive temperature or residence time; reduce barrel temps, check screw for dead spots. (3) Thickness Variation — die lip misalignment or uneven roll pressure; recalibrate die bolt torque pattern, verify roll parallelism. (4) Surface Lines/Streaks — contamination on die lips or damaged roll surfaces; clean die lips with copper tool, inspect rolls under magnification. (5) Internal Stress/Cracking — improper cooling gradient; adjust individual roll temperatures progressively (Roll 1 hottest, Roll 3 coolest). Jwell's after-sales team provides troubleshooting guides and remote diagnostic support for all scenarios.

PC sheet extrusion line - Jwell Machinery - Professional Extrusion Machine Manufacture

Q: How does a PC sheet extrusion line work?

A PC sheet extrusion line operates through a continuous process: (1) Raw PC granules are fed into the extruder hopper; (2) The screw system conveys, melts, and homogenizes the material through heated barrel zones (typically 260-300C for PC); (3) The molten polymer passes through a T-die that shapes it into a flat sheet with precise thickness control; (4) The sheet is calendered through a polishing roller stack (typically 3-roll) for surface finish and dimensional accuracy; (5) A cooling and haul-off system controls take-up speed and tension; (6) Finally, the sheet is cut to length or wound into rolls. Modern lines like Jwell's feature PLC-controlled temperature, speed, and pressure monitoring throughout.

Q: What industries and applications use PC sheets?

PC sheets serve diverse industries: Construction and Architecture — curtain wall glazing, canopies, sound barriers along highways, skylights, and partition walls; Transportation — train/bus windows, aircraft cabin windows, submarine viewports, motorcycle windshields, and automotive interior panels; Security and Defense — riot shields, ballistic visors, bank teller windows; Advertising and Signage — light box covers, display panels, POP stands; Agriculture — greenhouse panels; Electronics — LED light diffusers, instrument covers.

Frequently Asked Questions

Everything you need to know about PC sheet extrusion lines

1. What is a PC sheet and what are its key properties?

PC (polycarbonate) sheet is an amorphous thermoplastic material known for exceptional impact resistance — 250 times stronger than glass and 30 times stronger than acrylic (PMMA). Its key properties include:

Impact Strength: Outstanding toughness — virtually unbreakable under normal conditions
Optical Clarity: Light transmission up to 88%, excellent transparency
Temperature Range: Operating temperature from -40°C to +120°C
Flame Retardancy: V-0 to V-2 flame rating available
UV Stability: Can be co-extruded with UV-absorbing layers for outdoor use
Lightweight: Density ~1.2 g/cm³ — half the weight of glass

These characteristics make PC sheet ideal for applications requiring both transparency and durability, such as architectural glazing, safety shields, noise barriers, transportation windows, and security visors.

2. How does a PC sheet extrusion line work?

A PC sheet extrusion line operates through a continuous, tightly controlled process:

Material Feeding: Raw PC granules are fed into the extruder hopper via gravimetric or volumetric feeding
Melting & Homogenization: The screw system conveys, melts, and uniformly mixes the material through heated barrel zones (typically 260–300°C for PC)
Die Shaping: The molten polymer passes through a T-die (coat hanger type) that shapes it into a flat sheet with precise thickness distribution across the full width
Calendering: A 3-roll polishing stack provides surface finish (glossy/matte), cooling, and dimensional accuracy — each roll has independent temperature control
Haul-Off & Cooling: A rubberized nip roller system controls take-up speed and tension while air knives or water baths provide final cooling
Cutting/Winding: Flying saws cut sheets to length, or turret winders collect thinner gauges into rolls

Modern lines like Jwell’s feature Siemens PLC + ABB inverter automation with real-time monitoring of temperature zones, screw speed, melt pressure, motor load, and sheet thickness throughout every stage.

3. What are the differences between PC sheet, PMMA (acrylic), and glass?

Property	PC Sheet	PMMA (Acrylic)	Glass
Impact Strength	250x glass	18x glass	baseline
Light Transmission	~88%	~92%	~90%
Scratch Resistance	Moderate	Good	Excellent
Temperature Range	-40~+120°C	-40~+80°C	Wide
