Application Directions of 2-piece DRD Can Lines
Food Packaging Industry
Due to their high strength, reliable sealing performance, and seamless body structure, 2-piece DRD cans are widely used for meat products, fish products, soups, sauces, breakfast foods, and ready-to-eat meals. Their monoblock structure can withstand high-temperature sterilization processes, ensuring stable food quality.
Beverage and Functional Product Packaging
Although the beverage industry mainly uses 2-piece DWI technology, some functional drinks, small-volume beverages, and specialty metal containers still adopt DRD technology. The high-strength can body is suitable for products requiring pressure resistance, heating, or special filling conditions.
Chemical and Industrial Product Packaging
For small-capacity chemical products such as lubricating grease, adhesives, and laboratory reagents, the seamless structure of 2-piece DRD cans provides good corrosion resistance and sealing performance, ensuring content stability during storage and transportation.
Pharmaceutical and Nutritional Product Packaging
DRD cans offer excellent hygiene, strong body integrity, and controlled internal coating options, making them suitable for certain medicines, nutritional supplements, and products that require high packaging cleanliness.
Specialty Packaging and High-end Customized Containers
DRD production lines can flexibly produce various can shapes, such as oval, rounded-square, or deep-drawn styles. This makes them valuable for premium packaging applications, including gift foods, high-end food products, fine chemicals, and outdoor consumer goods.
Products with High Pressure or Strength Requirements
Because 2-piece DRD cans are formed through the continuous draw-and-redraw process, the resulting monoblock body offers higher strength. This makes them suitable for packaging products that require resistance to deformation, pressure filling, or harsh transportation conditions.
Advantages of 2-piece DRD Can Lines
- Seamless one-piece structure for reliable sealing performance
The DRD process forms the can body through a single deep drawing operation followed by multiple redraws, resulting in a seamless and continuous can wall. Without the side seam found in traditional three-piece cans, DRD cans offer enhanced sealing performance, leak resistance, and improved durability. This structure also minimizes the risk of corrosion caused by uneven coating at welded seams. - High-strength can body suitable for high-temperature and high-pressure processing
During deep drawing, the metal’s internal structure is redistributed and uniformly extended, significantly improving the can’s compressive strength. DRD cans are capable of withstanding retort sterilization, high-pressure filling, pasteurization, and mechanical impact during transportation, making them ideal for food, pet food, and chemical packaging. - Lightweight design that reduces material consumption and lowers costs
DRD cans can be produced with thinner walls while retaining their required strength. This lightweight design helps reduce metal usage and overall production costs while improving logistics efficiency, supporting sustainable manufacturing. - High dimensional accuracy and uniformity suitable for high-speed lines
Produced through a continuous automated process, DRD cans exhibit excellent consistency in roundness, sidewall height, and rim flatness. These qualities are crucial for smooth operation on high-speed filling machines, labeling systems, and automated packaging lines, greatly enhancing overall plant productivity. - More uniform internal coating for improved product safety
With no welded seams inside the can, internal coating is more evenly applied and adheres better. This reduces the risk of corrosion and metal migration, making DRD cans particularly suitable for acidic foods, protein-based products, pet wet food, and chemical contents that require higher protection. - Compatible with multiple metal materials such as tinplate, aluminum, and alloys
DRD can lines can be adjusted to accommodate different metals depending on product requirements. By optimizing die design, lubrication systems, and stroke control, the production line can efficiently process materials like tinplate for strength-intensive applications or aluminum for lightweight packaging. - Flexible can design options for diversified packaging needs
The DRD process enables the manufacturing of various can shapes, including round, oval, rectangular, and other specialty designs. This flexibility enhances product branding, supports premium packaging, and meets customized requirements for niche markets. - Easy maintenance and low long-term operating cost
Key components adopt standardized, durable modules, reducing maintenance frequency. Automated lubrication and monitoring systems provide early warnings for wear or abnormalities, minimizing downtime and ensuring stable daily operation.
