NC Carbon Fiber Coating Machine | Scraper Direct Coating & PET One-Time Forming Line

Looking for a professional coating machine that reliably produces NC carbon fiber? Conventional coating machines often struggle with special materials — uneven coating, poor forming results, and low production efficiency. The NC Carbon Fiber Coating Machine is built to solve exactly these problems: a dedicated system for efficient NC carbon fiber production, using scraper-type direct coating and PET one-time forming technology, ideal for professional production of special material products. Equipped with automatic lifting unwind, precision scraper coating head, 80-meter stainless steel oven, dual-station rotary rewind, and full touchscreen centralized control — it is the core production equipment for scaled NC carbon fiber manufacturing.

Why Choose This Machine: Five Core Advantages

Every design feature targets the specific process requirements of NC carbon fiber production — helping you stabilize quality and boost efficiency:

• Scraper direct coating + PET one-time forming, precise process: Uses scraper-type direct coating and PET one-time forming. Equipped with a 1.5KW three-phase asynchronous servo motor paired with an R-series worm gear reducer. Coating rollers are hard-chrome plated and super-finished, with a three-point adjustable doctor blade (comma bar). Coating thickness is precisely controlled and forming results are consistently stable.
• 80-meter stainless steel oven, thorough drying: Box-type fan oven with double-side door design, external electric heating tube box. Oven interior, exterior, and air ducts are all made of stainless steel. Equipped with 4KW high-efficiency cabinet fans, slot-type nozzles that can be pulled out for cleaning. The 80-meter oven ensures thorough drying and stable quality at low production speeds.
• Automatic lifting unwind + servo guidance, precise web travel: Single-station lifting unwind with two 3-inch keyed air shafts. 200N·M magnetic powder brake (Mitsubishi), Taiwan-made automatic tension controller with left-right weighing sensors. Unwind guidance uses ultrasonic sensor detection + electronic servo guidance — ensuring stable, drift-free web travel.
• Dual-station rotary rewind, roll changes without stopping: Dual-station rotary rewind mechanism. Rewind motor uses a three-phase asynchronous servo motor + Inovance rewind-type VFD (rewind shaft supports forward/reverse rotation). Equipped with two 3-inch keyed air shafts, two surface-hardened aluminum rollers, and transition anti-stick rollers. Convenient roll changes keep production running continuously.
• Full touchscreen centralized control, intelligent operation: Vertical cabinet centralized control with split cable operation. Intelligent temperature controllers + push-button settings. Both main cabinet and rewind station feature 10-inch touchscreens. 11 fan VFDs, 5 temperature controllers + 5 power regulators with fault alarm display. Coating head, unwind, control console, and rewind can each be independently started/stopped and speed-adjusted — intuitive and convenient operation.

Five Core Systems Breakdown:Every Component Built for NC Carbon Fiber Process

The machine has a total length of approximately 80 meters with an elevated oven structure. From PET film unwind to NC carbon fiber rewind, five systems work in seamless sequence to ensure stability and finished-product quality during special-material production:

1. Automatic Lifting Unwind System: Single-station lifting unwind mechanism with two 3-inch keyed air shafts. 200N·M magnetic powder brake (Mitsubishi) provides precise unwind tension control. Taiwan-made automatic tension controller with left-right weighing sensors achieves closed-loop tension control. Unwind guidance uses ultrasonic sensor detection + electronic servo guidance. Three-phase asynchronous motor with worm gear reducer ensures stable machine operation and drift-free web travel during unwinding.

   

2. Scraper-Type Direct Coating Head System: Uses scraper-type direct coating and PET one-time forming. Equipped with a 1.5KW three-phase asynchronous servo motor paired with an R-series worm gear reducer. Coating rollers are hard-chrome plated and super-finished, with a three-point adjustable doctor blade (comma bar). Adhesive layer thickness is precisely controlled, adapting to the special coating process requirements of NC carbon fiber.

   

3. Box-Type Fan Oven System + Crawler Conveyor System: Box-type fan oven with double-side door design and external electric heating tube box. Oven interior, exterior, and air ducts are all made of stainless steel. Equipped with 4KW high-efficiency cabinet fans, self-manufactured precision self-aligning bearings, slot-type nozzles that can be pulled out for cleaning, and manual worm-type dampers for exhaust adjustment. Crawler correction device uses linear guide rod with linear bearing mechanism, pneumatic correction, detection feedback signal interlocked with solenoid valve, automatic correction control. Limit infrared alarm mechanisms are installed on both sides of the crawler oven entrance — ensuring smooth and precise crawler operation.

   

4. Flattening + Cooling + Dual-Station Rotary Rewind System: Dual-station rotary rewind mechanism. Rewind motor uses a three-phase asynchronous servo motor + Inovance rewind-type VFD (rewind shaft supports forward/reverse rotation). Equipped with two 3-inch keyed air shafts, two surface-hardened aluminum rollers, and transition anti-stick rollers. Delivers neat, even winding with uniform tension. Dual-station design supports roll changes without stopping — high continuous production efficiency.

   

5. Electrical Control System: Vertical cabinet centralized control with split cable operation. Intelligent temperature controllers + push-button settings. Coating head, lifting unwind, control console, and rewind mechanism each support start, stop, and speed adjustment. Main cabinet features a 10-inch touchscreen, rewind station features another 10-inch touchscreen. 11 fan VFDs, 5 temperature controllers + 5 power regulators with fault alarm display — intuitive operation, clear fault indication, reducing operator skill requirements.
