Kettlebells material 

Kettlebells are sports equipment and built for long-term usage regardless of whether they are part of the professional or home gym set; accordingly, it is crucial to ensure the casting material’s stiffness and durability.

As a result, the two ideal metals that can perform excellently are cast iron and steel. Known as a company specializing in metal casting for many years and the manufacturer of thousands of kettlebells serving the world’s needs, we have a firm belief in offering the best service to consumers with cast iron and steel casting products.

The procedure uses cutting-edge technology to manufacture unique cast iron kettlebell sets according to customers’ requirements.

Our kettlebell casting methods

At our foundry, we make sure that our technique allows complex casting details on the kettlebell surface precisely, and we two technologies that we are using mainly are Lost foam casting and Green sand casting.

Finish kettlebell and foam patterns

The lost foam casting process

The lost foam method differs from most types of casting. Most traditional casting types remain some limitations because they require reusable patterns that must be withdrawn from the mold before casting. 

On the other hand, with the lost foam method technique, the foam patterns remain entirely in the mold during the casting process, and it is only evaporated when the molten metal is poured into the casting flask.

This improves kettlebells’ perfection, reduces surface defects remarkably, and secures the final products that maintain high precision, good surface texture, and exceptionally comfortable use. 

The green sand casting process

Green sand casting is one of the traditional casting types and the most popular technology in the casting industry. 

This technology uses green sand as the primary material to create the sand mold for the casting. Compared to Lost foam casting, it manufactures slightly rougher surface products but saves pattern making cost since one specific pattern can be used for mass production.

Surface treatment

No matter which method is used for making kettlebells, the roughcast product kettlebells still contain a certain amount of defects that affect smoothness and gripping feelings. Good material is not enough; our kettlebell’s surface must be perfect to benefit users’ fitness experience. 

Cast Iron Kettlebell made by VIC

VIC possesses an excellent engineering team with experience that takes care of surface treatment steps. 

In order to launch the finest kettlebell set to the market, each product has to go through the process of removing rough spots, excess edges and quality checks. 

In short, the kettlebell is put into the grinding and machining process, where excessive metals are removed by the tension of the grinding machine or hammer to eliminate rough spots and uneven edges for a smooth surface. 

Besides, our painting procedure is also worthy of mention. At the casting foundry, we implement:

  • Regular color painting (conventional liquid paint): various color choices
  • Powder coating (advanced technique): a free-flowing, dry powder that creates a hard finish more rigid than traditional paint, much thicker coatings than conventional liquid coatings without running or sagging that help conceals the protrusions.
