Semi/Full Rotary 2-in-1
Flexo Printing Machine

from Rhyguan: The All-in-One Solution for Short-Run, and High-Volume Production

The RF330 is a flexographic printing machine from Rhyguan that integrates both Semi-Rotary and Full-Rotary systems into a single unit. It allows seamless mode switching in just one step without disassembling the machine. It is designed to solve the most common dilemma faced by printing houses and packaging manufacturers: having to choose between a high-speed machine for large batches (which is cost-ineffective for urgent, low-volume jobs) and other printing types that are too slow for high-volume production.

The machine achieves continuous real production speeds of up to 180 meters/minute in Full-Rotary mode and 60 meters/minute in Semi-Rotary mode. It features color registration accuracy of ±0.1 mm, enhanced by a Dual-Anvil die-cutting system (the support roller is designed for two cutting pressure points per rotation) that operates swiftly up to 180 meters/minute. This makes the Rhyguan RF330 a highly cost-effective choice for many label and flexible packaging printing houses, often selected to replace the need for separate investments in both full-rotary and digital machines.

What is the RF330?

The RF330 is a flexo printing machine combining Semi-Rotary and Full-Rotary systems in the same machine. It is manufactured by Zhejiang Liguan Machinery under the Rhyguan brand. What sets the RF330 apart from standard flexo printers is its “One-Touch Mode Switching” system. This feature allows users to switch between Semi-Rotary mode (for short runs, urgent jobs, custom orders) and Full-Rotary mode (for large volume production) in a single step. This transition is done without machine disassembly or paper realignment, as both modes share the same web path and registration system

What problems does the RF330 solve for printing houses?

The flexible packaging and label printing market has evolved significantly. Industry data indicates that over 60%* of recent orders are custom, urgent, or short-run jobs. However, many printing houses still tackle this with high-cost methods, such as:

  • Investing in separate full-rotary and digital machines, which results in a total cost nearly double that of having a single machine.
  • Stocking a large number of printing cylinders and magnetic cylinders in advance, which ties up capital and delays return on investment (ROI).
  • Wasting time ordering new plates every time a customer changes designs or sizes, negatively impacting delivery schedules.

Furthermore, relying on traditional methods causes printing houses to lose their competitive edge when handling highly diverse orders. The RF330 Semi Full Rotary 2-in-1 flexo printer is specifically designed to directly address these three challenges. By combining two printing modes into one machine, operators can quickly switch workflows, reduce material waste during setup, minimize the financial burden of spare parts stocking, and maximize profit margins on every order whether short or long runs. This ensures the investment is cost-effective, yields rapid ROI, and elevates the production standards of printing houses to the next level.

Note: The 60% figure is based on the manufacturer’s majority customer data, not external market research.

Key Features of the RF330 Semi/Full Rotary 2-in-1 Flexo Printing Machine

Switch modes in a single step

without machine disassembly, eliminating the need for backup machines for varying job sizes.

Dual-Anvil die-cutting system (Patented)

cuts twice per shaft rotation, doubling the cutting frequency at a maximum speed of 180 meters/minute.

The Registration system

utilizes high-precision circular print position sensors (Leuze 1.5 mm) for perfect color alignment, reducing edge trim waste by up to 33% compared to conventional machines (13–15 mm).

Supports materials
as thin as 12 microns

opening opportunities for premium flexible packaging jobs.

The 120T Magnetic cylinder

is compatible with the 160T Printing cylinder, reducing job

Digital die-cutting pressure
control with 0.001 NPa

resolution reduces reliance on operator experience and minimizes waste from inaccurate setups.

Automatic Step Cold Foil control system

saves more than 50% on foil usage.

Case Study: A Printing House's Success
with the Dual-Mode System

Mr. Tao Wangxi, General Manager of Jiangxi Bona Printing Co., Ltd., a printing entrepreneur with over 20 years of direct industry experience, shared the top 3 challenges he faced before upgrading to a dual-mode system. His previous challenges included insufficient stock of printing cylinders leading to long lead times, tied-up capital from preparing plates and magnetic cylinders in advance, and heavy reliance on operator experience, which resulted in difficult setups and inconsistent accuracy.

“After switching to the dual-mode machine that switches in a single step, our team test-printed over 10 different actual product labels, including juice, tea, and coconut water labels, as well as packaging requiring cold foil stamping. The results were vibrant, sharp colors, perfectly smooth solid backgrounds, and flawless gradients without the banding lines commonly seen in standard prints. This level of quality is fully viable for real food and beverage brand labels.”

“Through continuous innovation and improvement, we have built core competitive advantages for our customers: lower costs, high efficiency, high precision, and high flexibility. This helps our business stand out in the market,” Mr. Tao stated.

Key Inquiries About the RF330

What is the maximum printing speed of the RF330?

In Full-Rotary mode, the RF330 has a stable production speed of up to 150 meters/minute, while the maximum mechanical speed according to specifications is 180 meters/minute (depending on material type and thickness). In Semi-Rotary mode, the maximum speed is 60 meters/minute, making it ideal for short-run and urgent jobs.

The RF330 utilizes a patented Dual-Anvil die-cutting system that cuts twice per shaft rotation (conventional machines cut once per rotation). This doubles the die-cutting frequency, allowing continuous operation at a maximum speed of 180 meters/minute.

Switching modes takes just seconds. The RF330 features a One-Touch Mode Switching system that completes the transition in a single step. Because both Semi-Rotary and Full-Rotary modes share the same web path and registration system, there is absolutely no need for machine disassembly or realignment.

The RF330 supports materials as thin as 12 microns (PET Film). This significantly surpasses the general industry standard of 30 microns, making the machine fully capable of producing premium flexible packaging.

The RF330 is primarily designed for FMCG (Fast-Moving Consumer Goods) labels and flexible packaging. It is highly suitable for beverage, juice, tea, and food product labels, as well as premium jobs requiring Cold Foil stamping. Its dual-mode capability makes it perfect for facilities managing a mix of customized short-run orders and continuous large-volume production.

No, a separate digital printer is not necessary for standard short-run and custom jobs. The RF330’s Semi-Rotary mode can print sizes as small as 50.8 mm without changing the printing cylinder, significantly reducing the need to invest in an additional digital machine. However, if your jobs require Variable Data Printing, a digital press remains the most suitable technology for that specific application.
