Overview
The NRC900 Fireworks Paper Kraft Core Tube Making Machine is a high-efficiency parallel paper tube machine engineered by NRC MACHINE (Qingdao New Richuan Precision Machine Co., Ltd). As a specialized tube making machine, it converts kraft paper or cardboard into parallel paper tubes via parallel winding, delivering robust, uniform cores ideal for fireworks and pyrotechnic applications.
This parallel paper tube making machine balances precision, durability, and affordability, making it the top choice for small-to-medium fireworks manufacturers.
What Is a Parallel Paper Tube Making Machine?
A parallel paper tube making machine is industrial equipment that produces straight, consistent-diameter paper tubes by winding paper layers in a parallel (axial) pattern, unlike spiral tube machines. For fireworks, these tubes must withstand internal pressure during ignition, resist deformation, and maintain strict dimensional uniformity—critical for safety and performance. The NRC900 excels here, with precision control over tube ID, wall thickness, and length.
Key Features of NRC900 Fireworks Paper Kraft Core Tube Making Machine
- Parallel Winding Technology: Ensures uniform wall thickness and straight seams, boosting tube strength and reliability for fireworks.
- Wide Material Compatibility: Works with kraft paper, cardboard, and other sturdy paper stocks (60–600gsm).
- Precision Control System: PLC (HEXIN or custom) + touchscreen + servo motors for stable, repeatable production.
- Adjustable Production Range: Flexible settings for inner diameter, length, and paper width to meet diverse fireworks tube needs.
- Compact & Efficient: Small footprint (2300×3200×1650mm) and low weight (~800kg) save factory space; only 1 operator needed.
- CE Certified: Complies with EU safety standards, ensuring safe operation and global market access.

FAQs
Q1: What makes the NRC900 paper core tube making machine different from spiral paper tube machines for fireworks?
A1: The NRC900 is a parallel paper tube making machine, producing straight, constant-diameter tubes with parallel layers. Spiral machines make tapered or spiral-seamed tubes, which are less durable and precise for fireworks. Parallel tubes offer higher crush resistance and consistent combustion, critical for safety.
Q2: What raw materials can the NRC900 use?
A2: It works with kraft paper, cardboard, and other sturdy paper stocks (60–600gsm). For fireworks, kraft paper is preferred for its high tensile strength and heat resistance.
Q3: How many operators are needed to run the NRC900?
A3: Only 1 operator is required for normal production, thanks to its fully automatic PLC control system. The operator monitors the touchscreen, refills paper rolls, and performs routine checks.
Q4: What’s the production speed and output of the NRC900?
A4: The speed ranges from 8–15m/min. Output depends on tube length: for 200mm-long tubes, it produces ~2,400–4,500 tubes per hour.
Q5: Is the NRC900 easy to maintain?
A5: Yes. It has a robust, low-wear design with easily accessible components. Routine maintenance includes lubricating moving parts, cleaning the glue system, and inspecting servo motors—tasks that take minimal time.
