Extensive knowledge of
manufacturing methods

Making the most of product performance by combining different manufacturing methods of casting and forging, Asano responds to the needs of the operation environments.

Unlimited potential for casting

Casting is the process of heating a metal to high temperature above the melting point for conversion into a liquid. The material is poured into a mold and then cooled to solidify in the intended shape.
Although it produces less strength compared to forging, using this technique, we can create metal products in shapes just as we imagined by highly flexible integral molding.

What Asano is searching for…

Asano has searched for better casting processes for a lotng time. Taking full advantage of the ease of creating products with rounded shapes, for example, Asano develops fishing products whose shapes enable smooth contact with ropes and nets as well as suppression of wear.
By increasing the thickness of portions where the load is applied, it is possible to create a shape by eliminating unnecessary portions, which enables us to manufacture lightweight yet sufficiently strong products at the proper prices. This flexibility in the production of items in various shapes through integral molding is the main feature of casting, and it is well used in Asano’s product development.

Strength of forging

Forging is the process of compressing a metal using a hammer to eliminate airspace inside the metal and miniaturize crystals to arrange their directions in order to enhance strength and form an intended shape.
While it is effective for products requiring strength, much cost is required to form unique shapes suitable for the intended use as in the case of creating cast pieces.

Combining the advantages of casting and forging

While Asano uses its advantageous casting technique for flexible molding, it adopts forged parts for products requiring high strength. For example, a swivel is a critical part used in block products and hung in high places for use. In order to add additional strength to this part, Asano adopts forged swivels.

By using forged parts to portions exposed to a load, Asano realizes both the shape suitable for its use and sufficient strength at the same time. In particular, in the case of fishing equipment, we need to respond to the severe requirements of our customers without fail because the strength and usability often affect fishing results. By combining the different characteristics of casting and forging, we are creating products in response to the conflicting needs of small size, light weight, and high strength.
