Metal Bending Basics

Metal has been an integral part of human culture for over 10,000 years. Ancient cultures used locally discovered metals such as copper, lead, iron and gold to create decorative items and tools. Some cultures even developed techniques to create stronger alloys over the centuries. Metals that could be bent into different shapes were very undesirable during ancient times. Much more effort was dedicated to creating materials that could withstand stress and pressure. It was not until much later when some of the first bending processes were developed.

Anvils And Hammers:

One of the oldest techniques used to bend metal involves a heat source, an anvil and a hammer. The metal is heated over an incredibly hot fire until it becomes malleable. A metalworker or blacksmith then uses a stable base like an anvil and a hammer to shape the metal. Each strike of the hammer deforms the piece until the correct curve or bend is achieved. This sometimes required a very long time since the piece would have to be repeatedly heated and pounded over the course of many hours. This is how some helmets, shields and decorative items were created.

Manual Brakes:

The first manual brakes started to appear before the industrial age. The first brakes were large machines that could not be easily moved. They were used in factories in order to create parts for construction, commercial exteriors and industrial equipment. They became very important in the emerging maritime industry. The brakes were not easy to use and required strength and skill. Manual brakes are still in use today although they are much lighter and often have features that make bends very accurate.

Modern Brakes:

A modern press brake was first developed during World War II in order to help streamline production of equipment and vehicles for the military. Most modern brakes use hydraulic, pneumatic or motorized systems to move a ram downwards into a sheet of metal. The ram pushes the metal into a specially cut die that allows a precision bend to be made. Press brakes are now so accurate and easy to use that a single person can produce dozens of pieces in a very short period of time.

Cutting-Edge Systems:

The latest press brakes, such as the Shenchong metal press brake, are connected to computers that use special software, live optical sensors and other tracking devices in order to remove the chance of an operator error or malfunction that could destroy a piece of metal. The computers also use pressure sensors to detect the performance of a ram when working with unusual metals. Computerization of advanced brakes is making it possible to produce increasingly sophisticated pieces for residential and industrial use.

Finding and Choosing a HVAC Contractor

It never fails that just as the weather hits triple digits, the air conditioning starts blowing hot air through the ducts. Alternatively, just as the first few snow flurries hit, the furnace decides to mysteriously malfunction.

When a central heating and cooling unit stops working correctly, finding a good HVAC contractor can add additional stress to an already difficult situation.

Knowledge is Power

Whenever news stories report on unethical contractors, the victims often share one key trait: they seldom have more than a passing familiarity with the work they hired someone to do. When it comes to choosing a good HVAC Service McDonough GA contractor, consumers can protect themselves by attaining at least a basic understanding of HVAC systems and how they work. Web-based resources abound to provide basic laymen-level instruction on the specifics of HVAC systems, but they can vary widely depending on the model and the type of system.

The best resource for learning about an HVAC system is the owner’s manual; this should have been given to the homeowner when the new unit was installed. If the manual is missing, examination of the unit should reveal the manufacturer and model number. A new owner’s manual can be ordered from the manufacturer, and some manufacturers make their owner’s manuals available online. You might actually be able to solve the problem by following this step first.

Understanding the Legalities

1.Contractors should have appropriate licensing, insurance, and be bonded. Many states require licensing for all HVAC contractors, but in some states, apprentices are not required to be licensed. While apprentices are legally obligated to work under the direct supervision of a licensed HVAC professional, some less ethical companies may send their apprentices to work unsupervised.

2.Homeowners should make certain that the HVAC technician performing their repairs and maintenance is personally licensed by the state. Even when the state does not require licensing, a technician who is licensed will be a better choice for quality repairs.

3.Insurance may be required by the state in order to meet contractor’s requirements, but large projects should also be backed by a surety bond. A contractor’s insurance will generally pay for any damages to the home or business caused by the contractor, either through negligence or accident. A contractor’s bond will reimburse homeowners for any breach of contract committed by the contractor. For example, if a contractor accidentally breaks a window with a toolbox, that damage would be paid by the insurance. If, on the other hand, a contractor takes a down payment and then disappears before completing the job, the down payment can be reimbursed by the bonding company.
