Frequently Asked Automotive Part Questions

Q.Where are fuses used?

A.A single vehicle makes use of fifty to sixty fuses. Most of these are in the fuse boxes installed in the engine compartment (under the hood) and vehicle interior (in front of the driver below the dash). I recommend taking a look at your own car to check.

Q.How many kinds of fuses are there?

A.Automotive fuses can be broadly divided into two categories: fast blow fuses that maintain circuits related to audio, lighting and so on, and slow blow fuses that maintain circuits related to batteries, motors and so on. Fast blow fuses began as glass tube fuses, growing into autofuses and then on to the current standard miniaturized autofuses called minifuses. Recently low-profile fuses have been developed, which are even smaller minifuses. Slow blow fuses are mainstream because, as their name suggests, they blow slower. And while all slow blow fuses blow slowly, there are many kinds based on the needs of automobile manufacturers. These also have recently evolved with new fuses such as the multi slow blow fuse that joins multiple circuits and the battery fuse terminal. A third kind of automotive fuses is the high voltage fuses required for hybrid vehicles.

Q.Do fuses blow?

A.Fuses are designed to cut off electrical flow: when the fuse's rated amperage is exceeded, the melting section dissolves. International standards specify the time before this cutting off occurs on a per amperage basis. Without fuses, electricity would continue to flow from the battery until the wiring melts apart, in some cases causing horrible fires.

Q.Do cars made outside Japan use fuses too?

A.All automobile manufacturers around the world use fuses. Autofuses, minifuses and low-profile fuses are all specified with international standards and used around the world. The fuses made by PEC are used in cars made in Japan, and then primarily in Korea, with other Asian countries as well.

Frequently Asked Precision Metal Forming Questions

Q.What kinds of products are made with “precision metal forming?”

A.We make and sell precision metal press formed parts using pure aluminum, aluminum alloys, surface-processing steel sheets and copper alloy as materials. Our products cover a wide range of differing functionality and intended application, such as electromagnetic shielding for LCD panels, enclosures, structures, reinforcing parts and other automotive electronic part circuitry. We have also begun recently to produce deep-drawn battery cell cans and EcoCute water heater parts.

Q.Where are formed products delivered?

A.Sony, Sharp and other large home appliance makers are our primary clients, but we have been getting more business with automotive makers recently.

Q.What kind of technology does PEC apply?

A.The foundations of our press production include our precision metal forming design and deep drawing.

Q.What is deep drawing processing?

A.Deep drawing is a method of creating a 3D shape by applying a number of strokes to a single sheet of metal.

Q.What kinds of EcoCute parts does PEC make?

A.Parts for devices outside the tank, which provides hot water for water heaters, bathtubs, washing machines and so on.
