The loss of electricity supply is technically called as power outage. It is specifically referred to as “brownout” when some power is lost but retained some voltage level, albeit not enough for the minimum level required by a certain system. On the other hand, it is called “blackout” when the power is completely lost.

When power failures occur, your appliances or any other electronic devices are the things that suffer most from the damaging. Your computer unit is featured with a power supply, a device that is used in generating electricity to keep it operational. The switcher technology of this device will convert the alternating current line into direct current input. This enables the computer to start functioning. However, once a power outage occurs it will stop producing power. As a result, the computer will end its operation. As mentioned, this occurrence is detrimental to your computer. If this incident continues to occur, it will suffer serious damage and require extensive repairs that could run into a lot of money.

Fortunately though, there is a device that counters the situation in the form of Uninterruptible Power Supply or UPS. A UPS is a device used to protect computers and electronic equipment from the damaging effects of power outage incidents. It is a battery-driven power supply that is active even whenever sudden loss of power has occurred. There are certain types of uninterruptible power supplies with variety of capacities. There is a small unit type that can service a single computer in a home or office. There is also the kind that can provide protection to a business environment that runs with a big computer network.

Uninterruptible power supplies are necessary tools both in large business establishments with a wide network of computers and in a home/office with individual computers.

In the tool and die world, carbide dies have several key advantages for certain precision metal stamping operations requiring long life and high volume stamping runs. Carbide is harder than steel, is highly wear resistant, and can withstand very high compressive loading.

Tungsten carbide is a cemented carbide made up of Tungsten (W), Carbon (C), and a binder such as cobalt or nickel. By changing the amount of binder, the properties of Tungsten Carbide can be adjusted to obtain specific properties needed for various applications. For example, increasing the amount of binder results in higher impact resistance, but less wear resistance. Conversely, decreasing the amount of binder results in higher hardness, but less fracture toughness. Hence, a proper understanding of the various grades of carbide can increase the chances of having a successfully designed carbide die.

The selection of a carbide die (over a steel die) is a consideration that should be made during the design stage of the component that is to be stamped. For applications requiring very high volumes, carbide tooling may be a good selection. Examples of this would be applications such as: lamination for the rotors/stators in motors or for transformers, surgical components, bearings, electronic connector pins, and many other applications.

The benefits of using carbide tooling for certain progressive die applications include: higher wear resistance, reduced die maintenance, and less downtime. These three benefits are inherently due to the higher wear resistance provided by the use of tungsten carbide. Higher wear resistance results in longer running times between necessary maintenance for a carbide die as compared to a steel progressive die. Although carbide tooling still requires preventive maintenance, the less frequent maintenance intervals oftentimes result in a lower life cycle (total) cost for certain precision stamped components.
