Comprehensive services from trial manufacturing to mass production

We offer a system which can provide everything from trial production to mass production of products by maintaining a self-hardening (hand casting) trial production factory to mass production lines with automatic casting machines

Both cast iron and aluminum handled at a single factory

Melting both cast iron and aluminum allows for trial production of both in a single mold, and also makes it possible to use compound cast iron and aluminum technologies (cast-in inserts)

Trial production systems capable of meeting extremely tight deadlines

Our self-hardening line has a proven track record of experience and results in production of a wide variety of quick turnaround, high difficulty cast components, particularly in trial manufacturing of aluminum castings for automotive parts. In addition to producing molds at our in-house factorys, we also increasingly handle direct fabrication of sand molds (casting molds) from 3D CAD data, allowing for even faster turnaround times.

We can produce cast products in as little as 10 days if 3D CAD data is available. This is the optimum method for cases where procurement deadline is the priority, or when producing only 1 cast product with no die.


Optimal casting plan design using simulation technologies

Controlling blowholes which occur inside castings is a major issue for the casting process. The introduction of casting fluidity simulations allows for the prediction of where blowholes will occur (defect occurrence locations), which makes it possible to design optimal casting plans.

Inspection and quality assurance systems backed by abundant experience in the trial production business

In order to establish a satisfactory quality assurance system, we employ not only inspection equipment within our factorys, but also utilize inspection equipment at group companies and affiliate manufacturers based on customer requirements.

Low pressure die casting method which can minimize aluminum defects

Low pressure die casting is a casting method which differs from conventional casting methods where molten metal is poured from above, by instead filling the molten metal from below to minimize the introduction of any air pockets or inclusion, which in turn greatly reduces defects. The low pressure die casting method is well suited to an effective for casting of products such as complex shape products in which it is difficult to prevent blowhole formation, and products with high processing loss from blowholes.

Conventional method: Sand mold gravity casting


Cast-in joining technologies for ferrous and aluminum metals

One of SHINKOH METAL's major strengths is that we have our own cast iron and aluminum casting factory which is also capable of "cast-in" technologies where ferrous metals (cast iron, stainless steel, etc.) are cast inside of aluminum castings. As industrial machine parts have continued to become more compact and more advanced in recent years, there has also been an increase in cast-in technology needs.

  • Technology overview

    Aluminum/ferrous metal mixed castings require review of design and forms for cast-in part core prints. In addition, as there will be no adhesion between the differing materials, it is also important to maintain control in order to prevent any gaps from occurring.

  • Value provided by technology

    Casting-in of pipes provides the component with its own cooling feature, which both improves cooling performance and also saves space.
