ABOUT THE CAROSUNG

Established initially as Lifeng Hardware Co. Ltd in 2005, we began to produce custom belts for the global market. Continuously pushing the envelope forward, we developed a mature supply chain, elevated our production process, and offered various value-added services to become the one-stop shop for clients. In 2016, wanting to strengthen our presence in the market, we’ve developed our own brand, Carosung.

Mold Making

Step.1 Mold Making

Based on the design you’ve selected or provided by our expert designers, a detailed layout is drafted to create the mold. The cavity within the mold shows the intricate designs that will form the cast.

Step.2 Die Casting

Premium metal material is molten and inserted into the mold using specialized tools, casting the detailed design. The steel’s temperature is slowly brought down, increasing its tensile strength and reducing breakage.

Step.3 Polishing

Once the metal has hardened and cooled to the touch, they are taken out of the mold and polished to bring out the intricate details. The piece is then electroplated, adding a layer of protection and shine.

Step.4 Plating Color

To further increase the aesthetics of the custom belt and buckle, we use enhanced electroplating techniques to add color to the piece. The colors not only last longer but are also bright and attractive.

Step.5 Embossing or Laser logo

An embossed or laser-printed logo on your custom belts and buckles elevates its personality and branding. We use precision embossing tools to stamp your brand on the product, making sure they are detailed and precise.

Assembly

Step.6 Assembly

Prepare tools and parts, clean the workspace, install base, frame, supports, movable parts, and hardware accessories in order, and finally check for sturdiness and functionality.

Quality inspection

Step.7 Testing & Quality inspection

Checking appearance, dimensions, material properties, functionality, and packaging. Results determine if items are qualified. Defective items are isolated and feedback is given for improvement.

Packaging

Step.8 Packaging

Counting and cleaning the items, selecting suitable packaging materials, filling, securing, sealing, and labeling, and finally inspecting the quality to ensure it is sturdy, neat, and clearly marked.
