Product Introduction
Stable board control from feeding to die cutting
The BONXI 1224 full vacuum machine is engineered for high-output corrugated carton plants that need consistent board transport, accurate multi-color registration and fast job changeovers. Mechanical lead-edge feeding with encoder control delivers the sheet into four vacuum-transfer printing sections, reducing slip and compression on warped or lightweight board.
PLC control, automatic zero return and digital size adjustment shorten setup time. The selected line configuration combines a six-shaft large pre-creasing slotter with a four-shaft rotary die cutter for reliable inline production of regular slotted cartons and die-cut packaging.
Key Features
Designed for productive four-color carton converting
Every core section is coordinated through the central control system for faster setup, stable transfer and repeatable production.
Accurate 4-Color Printing
Precision-ground cylinders, synchronized drive components and controlled printing pressure support multi-color registration within ±0.5 mm.
Fast Digital Setup
One-touch setup, PLC control, automatic zero return and digital size entry reduce trial sheets and operator adjustment time.
Large Pre-Creasing Slotter
A six-shaft slotting section with pre-creasing, synchronized electric adjustment and anti-collision protection handles demanding carton layouts.
Rotary Die Cutting
Electric phase, axial and gap adjustment improve setup speed, while automatic zero return helps reduce board waste during changeovers.
Heavy-Duty Construction
60 mm wallboards, ground 20CrMnTi transmission gears, keyless locking assemblies and hardened chrome surfaces support long service life.

Frequently Asked Questions
1224 full vacuum flexo line FAQ
What does full vacuum adsorption mean on this machine?
Vacuum support carries the corrugated sheet through each printing section. The suction pressure and working width can be adjusted to the board size and curvature, improving transfer stability and color registration.
Which corrugated board types can the 1224 machine process?
The machine is designed for common A, B, C, E and F flute three-layer board and combined five-layer corrugated board within the 2–12 mm thickness range.
Is 230 sheets per minute the normal production speed?
230 sheets/min is the maximum mechanical speed. The recommended economic speed is 150–180 sheets/min. Actual output depends on board quality, sheet size, print coverage, tooling and operator setup.
Can the machine configuration be customized?
Yes. Anilox type, inking system, electrical standard, waste stripping, automatic stacking and other line modules can be configured according to the carton structure and production target.
What information is needed for a quotation?
Please provide maximum and minimum sheet sizes, flute types, printing colors, target output, carton samples or drawings, die-cutting requirements and the destination electrical standard.
Does BONXI provide installation and training?
Installation, commissioning and operator-maintenance training can be included in the project service plan. Site preparation, schedule and travel terms are confirmed in the final contract.
