Introduction

           Linear screen printing machines are one of the earliest developed and most technologically advanced types of fully automatic screen printing equipment available on the market. Due to their unique linear structure, multiple printing units can be seamlessly connected to create a complete automatic production line. Because of this long, continuous configuration, the machine is widely known in the industry as a “Screen Printing Dragon.” The automatic screen printing machine is specially designed for high-volume printing on plastic hollow containers, offering excellent printing accuracy, production efficiency, and stability. It is widely used in industries such as cosmetics, pharmaceuticals, lubricants, food packaging, detergents, and daily chemical products.   The open structure design of the screen printing dragon allows manufacturers to achieve high-precision multi-color printing with up to 10 colors. The registration accuracy can reach 0.08–0.1 mm, making it ideal for demanding applications where precise color alignment and consistent printing quality are required.

Standardized Structure of Screen Printing Dragon

With years of development, the structure of the screen printing dragon has become highly standardized. Each printing unit integrates three essential processes:

• Surface treatment
•  Precision screen printing
• UV curing

This integrated design allows the machine to print directly on polyolefin materials and various plastic products without additional processing.

The main components of a fully automatic screen printing machine include:

1. Automatic Feeding Conveyor System

        The feeding conveyor automatically transfers unprinted products into the printing line.  Operators can place containers directly onto the conveyor belt, and the feeding mechanism automatically picks and positions the bottles onto the printing table.   For high-volume production, an automatic feeding hopper can also be customized. Bottles are automatically organized and transferred into the printing system, significantly reducing manual operation requirements.

2. Pre-Press Treatment System

Before printing, plastic containers usually require surface treatment to improve ink adhesion.

The pre-treatment system may include:

• Flame treatment
• Plasma treatment
• PP surface activation treatment
• Other customized surface preparation solutions

These processes ensure excellent ink adhesion and long-lasting printing performance.

3. Precision Automatic Screen Printing Unit

The printing system is based on the proven technology of semi-automatic screen printers but incorporates advanced automation technologies for higher efficiency and precision.

Modern automatic screen printing machines use:

• Servo motor control systems
• High-performance pneumatic components
• International brand electrical components
• High-strength steel machine structures

Compared with traditional aluminum profile structures, steel components provide better durability, vibration resistance, and longer service life, ensuring stable operation during continuous production.

4. UV Curing and UV LED Drying System

        For high-speed continuous screen printing, UV curing technology is essential.   UV inks remain stable on the screen surface and only cure when exposed to ultraviolet light. This prevents ink drying problems, reduces downtime, and improves printing consistency.  Manufacturers can choose traditional UV curing systems or energy-efficient UV LED curing systems according to production requirements.

5. Automatic Unloading System

         After printing and curing, finished products are automatically transferred through the unloading system.  For simple production requirements, a standard unloading conveyor is sufficient.  For applications requiring product arrangement and packaging preparation, the machine can be equipped with an automatic robotic unloading system to place finished containers in an organized manner.

Compared with traditional printing methods, the fully automatic screen printing machine provides:

• High-speed continuous production
• Excellent color registration accuracy
• Thick and durable ink coverage
• High gloss printing effects
• Strong ink adhesion
• Stable printing quality for mass production

This makes it an ideal plastic container screen printing machine for manufacturers producing bottles, jars, and hollow plastic packaging.

Applications of Automatic Container Screen Printing Machine

Plastic hollow containers are widely used in industries including:

• Pharmaceutical packaging  /Cosmetic bottles and containers  / Detergent packaging  /Lubricant containers  /Beverage packaging  /Household products  /Chemical packaging

           These containers are commonly manufactured through blow molding processes using materials such as PP, PE, PET, and PC. With increasing labor costs and growing market competition, more manufacturers are replacing manual or semi-automatic printing processes with fully automatic screen printing solutions to improve productivity and reduce production costs.
