Learn More About Flexo Printing Machines, Features, Applications and Solutions.

Pre-sales Service

What kind of support can you provide during the pre-sales stage?

During the pre-sales stage, we provide flexographic printing machine selection recommendations, process solution analysis, and production line configuration suggestions based on the customer’s product type, material characteristics (such as PE, PP, paper, etc.), and production capacity requirements, helping customers choose the most suitable equipment solution.

Yes. We support material testing and printing sample services to help customers confirm printing results, color performance, and material compatibility before purchasing, reducing selection risks.

Yes, we can arrange factory visits or online video factory inspections, allowing customers to directly understand the equipment manufacturing process, assembly standards, and actual operating conditions.

In-sales Service

How do you follow up on equipment production during the sales stage?

During the equipment production process, we regularly update production progress and maintain communication with customers to ensure that equipment configuration, functional modules, and technical parameters meet order requirements.

Depending on the machine model and configuration, the standard flexographic printing machine production cycle is usually 60–120 days. Customized configurations may take slightly longer. We will clearly specify the delivery time in the contract.

Yes, all equipment undergoes complete testing before leaving the factory, including operational stability, registration accuracy, tension control system, and basic printing tests, ensuring the equipment meets factory standards.

Yes, after equipment delivery we continue to provide long-term technical support, including operation guidance, parameter optimization suggestions, and ongoing troubleshooting during production, ensuring stable customer production.

After-sales Service

How is after-sales service mainly provided?

We mainly provide fast-response after-sales service through remote video, online guidance, and technical support, helping solve problems during equipment installation, commissioning, and production.

We can provide equipment function upgrade suggestions, process optimization guidance, and operating parameter adjustment support based on customer production needs, helping customers continuously improve production efficiency and printing quality.

Wearing parts of the equipment can be replaced free of charge within the one-year warranty period, ensuring stable customer production and reducing maintenance costs.

About the Machine

What is a Gearless Flexo Printing Press?

A gearless flexo printing press uses independent servo motors instead of traditional mechanical gears to drive each printing unit. This improves printing precision, reduces mechanical wear, and allows faster job changeover with lower maintenance requirements. It is especially suitable for high-quality flexible packaging printing.

A CI (Central Impression) flexo printing machine features all printing units arranged around a single large central impression cylinder. The substrate is held tightly on the central drum during printing, ensuring excellent color registration and stable printing quality, especially for film-based materials.

A stack flexo printing machine has its printing units arranged vertically in a stacked structure. Each color unit operates independently, making it suitable for printing paper, non-woven fabrics, and packaging materials that require flexible configuration and easy operation.

An inline flexo printing machine arranges printing units in a straight horizontal line. The substrate passes through each unit sequentially. It offers high flexibility in production, easy integration with other converting processes, and is widely used for labels and paper-based packaging.

CI Flexo: Best for high-speed, high-precision film printing with superior registration accuracy
Stack Flexo: Compact structure, ideal for paper and non-woven materials
Inline Flexo: Highly flexible, suitable for multi-process production lines and label printing

Flexo printing machines can print on a wide range of substrates, including PE, PP, BOPP, PET films, paper, aluminum foil, non-woven fabrics, and laminated materials used in packaging industries.

They are widely used in flexible packaging, food packaging, beverage packaging, pharmaceutical packaging, hygiene products, labels, and industrial packaging applications.

Gearless technology improves registration accuracy, reduces vibration, minimizes maintenance costs, and enables faster job changes. It is ideal for modern high-speed and multi-color printing demands.

Yes. Most modern flexo presses support water-based and solvent-based inks, making them suitable for environmentally friendly and low-VOC packaging production.

The choice depends on your material type, production speed, print quality requirements, and application:

  • High-end film packaging → CI Gearless Flexo Press
  • Paper bags & nonwoven → Stack Flexo Machine
  • Label & multi-process production → Inline Flexo Machine
