Sheet Metal Forming

The very first thing you would want to know about sheet metal is that its ratio of surface area to volume is very high. Many people confuse sheet metal with plate metal. While both may look similar to the untrained eye, they are very different. The thickness of sheet metal is 1/4 inch or less, while plate metal is more than 1/4 inch in thickness.

While sheet metal is used to manufacture automobile bodies, roofing, airplane wings, beverage cans and the like, plate metal is used to make boilers, bridges, ships, turbines and so on. Plate metal is used for larger parts. While some manufacturing processes used for sheet metal work also can be used with plate metal, generally plate metal requires specialized tools and processes.

Cutting, bending and deep drawing are the main kinds of sheet metal working.

Sheet metal operations are typically performed on a metal press brake using dies and punches. This is perhaps the most economical method when it comes to forming of sheet metal.

Before designing a punch and die set, understanding the mechanics of sheet metal deformation is vital. Without a very good understanding of how this behaves, it will be impossible to produce parts to accurate tolerances and specifications.

Metals such as brass, aluminum, copper, stainless steel, nickel and tin are perhaps the most commonly used ones for making sheet metal. That said, gold, silver, titanium and platinum are also used.

It would be vital to have an excellent understanding of how a given material behaves under stress, how it deforms, and so on. Typically, you would want the material to undergo significant plastic deformation before necking. Localized necking is to be avoided. You would also want to take care to avoid uneven elongation which some materials like low carbon steels are prone to. This can lead to poor surface finish and other unacceptable parameters.

In short, you would need to have an extremely good understanding of how a given material behaves under stress. And different materials can exhibit very different behaviors.

In addition to having a good understanding of how a particular material behaves under stress, you would also want to conduct tests on samples before you start working on a given lot of raw material. You would want to conduct tests to verify raw material composition, tension tests, cupping test and any other tests that may be required. These tests would give you a much better understanding of the raw material.


Heating, Ventilation and Air Conditioning (HVAC) is most commonly associated with the common residential household air conditioner/furnace, or the mechanical system that provides heating and cooling in a commercial building or multi-residential building.

When integrated mechanical systems are applied to large industrial plants and industrial buildings representing high energy consumers, the HVAC system becomes a much larger element of the equation, as it has to work in harmony with the other components of the system.

Each individual industrial process can represent a multitude of conditions that are required to be controlled to precise indoor climates and conditions; all the while outdoor varying seasonal conditions greatly affect the HVAC equipment’s efficiency depending on geographical location.

In business, efficient HVAC systems power your productivity and profitability. Expert engineers from HVAC Service Cartersville GA know how to increase your building’s comfort, lower operating costs, and create a healthier indoor environment. From light commercial heating and cooling systems to heat pumps, air conditioners and air and water cooled package units, HVAC systems deliver indoor air quality benefits for a long list of applications.

Is Waterproofing a Basement a Good Solution for Our Home?

Waterproofing a basement in Toronto will help you avoid some big problems which may arise in the future. You just have to find the best ways to seal up your basement and to keep the water outside, where it should be!

Waterproofing a basement is one of the solutions which can help you for avoid the problems that may appear at your ventilation systems and, the most important of all, it will help you avoid the leaks in the foundations, in the ceilings or in the walls.

Waterproofing a basement is sometimes the solution which saves homeowners from some big disasters – if the electrical wires, the garbage disposals and the sewage and the water pipes are all installed in their basement. So, even if you are not in the mood of waterproofing a basement, or you do not have enough money to do it, you need to find the necessary resources because this will help for sure in the future and it will also help you avoid some problems which may turn into disasters!

If you decide to do this, you need to know that there a few steps that need to be followed when we are speaking about waterproofing a basement.

First of all you need to apply a waterproofing coating – before doing this, you have to inspect the walls to see if they are in a good condition and if they are not, you need to repair the broken parts, to fill in the hoes that are in the walls, to remove the old paint and to use some fresh paint.

If you have the necessary skills, you should do this by yourself you will save money and you will also be sure that the job is well done. If you do not know how to do it, you should call basement waterproofing Toronto Professionals who can help you waterproofing your basement. Waterproofing coatings can be used for exterior and interior applications and for below or above ground.

Specialists say that when we are thinking about waterproofing a basement, we should know that exterior waterproofing is much better than the interior one and that the exterior waterproofing has some advantages that we should know:

Area covered – this means that everything is covered and that water cannot enter your basement – interior waterproofing only keeps the water out of your basement, but it does not keep it out of the walls of your basement. This may have certain negative consequences – it may affect the paint from the walls and even the pipes and the wires which are located in the basement.

Mildew and mold appear in humid and moist conditions and this is why exterior waterproofing a basement can be the best solution – the water will not enter your basement through your walls and you will able to avoid mold and mildew, as they can affect the walls and they can cause respiratory problems.

Not many people know that waterproofing a basement is necessary, and maybe these things will help them take the right decision in order to avoid some problems that could arise in the future!
