HODEN SEIMITSU KAKO KENKYUSHO CO., LTD.

about this company

Vision/Mission

We have two goals:

1. Our ZENFormer, which is the most precise pressing machine in the world, shall become the global standard.

2. Change from a processing company to a gas turbine & jet engine parts manufacturer.

 

Business Description

We operate in three countries: Japan, Thailand, and China. In Japan our company group has 9 plants: Narita, Atsugi, Iiyama, Zama, Nagoya, Komaki, Kasugai, Wakasa, and Okayama.

Our company is active in three business segments:
1. Electrical discharge machining and surface treatment;
2. Die and molds;
3. Machinery.

Our market is all over the world, and targeted industries are aviation and space, housing, transportation, environment and energy, machinery and equipment.

 

Background

Our first key milestone since our establishment in 1961 was in 1963, when we started manufacturing aluminum extrusion dies and became the top manufacturer in Japan, and we have been doing business with our main client, Lixil, for over 40 years. Our second milestone was in 1973, when we started manufacturing the extrusion dies for the ceramic honeycomb, which we are also the top manufacturer in Japan for. Our main client here is NGK Insulators.

We originally started in the airplane engine parts business around 1965 for EDM (electrical discharge machining) but in 1981 we started the surface treatment for airplane engine parts, which have become a key factor in our special treatment business. In 1985, we started manufacturing gas turbine parts using our special technologies of EDM and ECM (electro chemical machining).

Our fifth milestone was in 1991 when we founded the base of press machine. This is a digital machine called the digital servo press, which cannot be found anywhere else in the world.

These milestones are all visible achievements that we have accomplished.

We really think that being at the forefront is in our DNA and we respond to our clients’ needs 100%. Our spirit is to positively deny the current situation because there is always a limitation to it and things expire, so we always have to look for the next innovations.

 

Products/Services

Electrical Discharge Machining

Electrical discharge machining meets a wide array of customer needs by using three methods: die-sinking electrical discharge machining, wire-cut electrical discharge machining, and electrochemical machining. As die-sinking electrical discharge machining allows for machining in accordance with the shape of the electrode, it is sometimes referred to as transfer machining. It is applied in many fields as it allows for the metal to take various forms.

Wire-cut electrical discharge machining uses thread-like electrodes, and is a machining method that enables cutting of complex forms from metal. It is an essential technology for precision machining.

Electrochemical machining is a machining method using electrolytic action. Because it allows long and narrow holes to be created, it is primarily used to make cooling holes in industrial gas turbine parts.

 

Surface Treatment

Surface treatment improves metal durability. SermeTel is a coating technology introduced from America. It is heat- and rust-resistant, and is primarily used in surface treatment of industrial gas turbine and aeroengine parts. Thermal spraying improves part durability by heating up particulate material, such as metal and spraying it on other metal. It is primarily used on industrial gas turbine and aeroengine parts.

ZECCOAT is a pioneering corrosion-resistant and world’s first completely chromium-free surface treatment agent innovated by HSK.

Under the expanding a regulations to limit the use of chromium in many countries, ZECCOAT has attracted the attention of industries to comply with future environmental regulations.

 

Dies and molds

Dies play a critical role in manufacturing, but stable die mass production was difficult due to variations in accuracy, cost, and delivery requirements.

Therefore, HSK developed the pioneering original DMM (digital meister method) system.

The know-how of skilled engineers was converted to numeric figures to realize a high–precision NC process that contributed to the stable production of dies. Thanks to the DMM system, HSK became the biggest manufacturer and supplier of aluminum and ceramics extrusion dies in Japan.

 

Machinery

HSK can respond to many customer needs, which range from development, manufacturing, and sales of creative press machines to contract processing of parts. Normally, if the pressure of the processing surface is not constant, inclination occurs inside the press. By controlling four axes independently, the ZENFormer direct-acting digital servo press maintains the correct position and achieves nano-level control by applying varying pressure on each axis. Press processing with the ZENFormer has realized new high-accuracy manufacturing processes at a substantially reduced cost.
