Automotive Parts FAQ

Where are fuses used?
Automobiles are equipped with some 50-60 fuses per vehicle. The bulk of these are stored in fuse boxes installed in the engine compartment (below the hood) and the passenger compartment (under the instrument panel in front of the driver’s seat). It is a good idea to confirm the location of the fuse boxes in your vehicle.
How many types of fuses are there?
Automotive fuses can be broadly divided into fast-acting fuses that protect audio and lamp circuits and time-delay fuses that protect the car battery and motor circuits. Fast-acting fuses evolved from the older glass-tube fuses into auto fuses and later into mini fuses (compact auto fuses), which are the standard today. Recently, low-profile fuses that are even more compact than mini fuses have also appeared on the market. Among time-delay fuses, slow blow fuses are the most common type. Although often used as a generic term, slow blow fuses are available in many different shapes depending on automaker needs. Advances in slow blow fuses have given rise to new types such as multi slow blow fuses, which protect multiple circuits, and battery terminal fuses. There are also special fuses for hybrid and other high-voltage vehicles.
Do fuses wear out over time?
When exposed to an electric current that exceeds its carrying capacity, the metal wire inside a fuse is designed to melt in order to interrupt the current. The time required for the wire to melt is rated for various currents based on international standards. In the absence of fuses, current would continue to flow from the battery and may cause a fire in the worst-case scenario.
Are fuses also used in foreign-made automobiles?
Fuses are used by automakers all over the world. Auto fuses, mini fuses and low-profile fuses are governed by international standards and used in vehicles across the world. Our auto fuses, mini fuses and profile fuses are used in vehicles manufactured in Japan as well as in South Korea and elsewhere in Asia.

Precision-Metal Processing FAQ

Which products do you manufacture through precision metal processing?
We manufacture and sell precision press-forming products made from basic materials such as pure aluminum, aluminum alloy, surface-treated steel and copper alloy. Our products cover a wide range of functions and applications including electromagnetic interference shielding materials for LCD panels, packages, structural parts, reinforcement parts and circuit parts for automotive electronic components. Some examples of specific products we have recently manufactured are eco-cute parts and deep-drawn battery cases.
Who do you supply your processed products to?
We mainly supply our products to leading home-appliance makers such as Sony and Sharp. More recently, however, we have also expanded transactions with auto parts makers.
Which technologies do you use to manufacture these products?
We mainly manufacture precision parts based on precision die design and deep drawing.
What does deep drawing processing entail?
Deep drawing refers to the manufacturing of a three-dimensional product by applying several processes to a single metal sheet.
What kind of products are eco-cute parts?
The eco-cute parts we manufacture are exterior parts of tanks that produce hot water for hot-water heaters, baths and washing machines.
