4 Litre F Style Metal Cans

4-liter Type F Style Metal Cans are rectangular metal packaging containers with a 1-gallon capacity. Their signature "F" shape (narrowed at the top and equipped with a handle) makes them very easy to pour. They are widely used in the automotive, chemical, and consumer goods industries, primarily for packaging liquid products such as engine oils, paints, and solvents.

1. Square Structure Design: Flat sides facilitate labeling and printing, stable stacking, and saves storage and transportation space.

2. Robust and Durable: Impact-resistant and deformation-resistant tinplate material, suitable for industrial environments.

3. Excellent Sealing Performance: Can be equipped with metal, plastic, or spout lids to ensure no leakage.

4. Handle Design: Optional plastic or curved metal handles for easy handling.

5. Customizable Height: Appearance printing, height, and lid type can all be adjusted according to customer requirements.

Liquid products such as paint and motor oil have extremely high requirements for packaging sealing, and leakage during transportation must be avoided to prevent product loss or contamination. Leakage of chemical products may cause safety hazards (such as corrosion and flammability). DS Packaging will ensure sealing reliability through structural design (such as inner cover, sealing ring, rubber strip, lock and other accessories), material strength (such as tinplate thickness), and production process (such as double-layer crimping process, multi-layer crimping joint, etc.). Before leaving the factory, it will be tested by a fully automatic leak detector, or manual sampling and pressure testing with professional equipment (such as drop and shock tests) to ensure that the metal packaging is leak-free.

1. Production speed: For example, the actual stable production capacity of DS Packaging's 4L Rectangular Tin Can is 65~85pcs/minute, and the daily output (24 hours) is 93,000~22,000pcs; the actual stable production capacity of 20L Conical Tinplate Pails is 28~38pcs/minute, and the daily output (22 hours) is 37,000~50,000pcs, which fully meets the needs of large-volume orders.

2. Specification switching: The production line supports specification switching (such as can height and diameter adjustment) within 30 minutes, without complex tools, reducing downtime.

3. Fast assembly of accessories: Key components (such as upper cover punching and sealing molds) adopt modular design and can be replaced within 5 minutes, reducing downtime.

4. Automation degree: The entire line adopts a PLC control system to realize the integration of automatic welding into rounding, square, flanging, sealing, and airtightness detection, reducing manual intervention and improving efficiency by more than 30%.
