Manufacturing windows at the factory

window factory

The manufacture of PVC windows is a complex process, requiring the use of advanced equipment and quality control at all stages of production. Compliance with the production technology alone ensures that the final product meets the standards of environmental friendliness and has high-performance characteristics. A lot of people wonder about the window manufacturing process at the factory. We will try to answer this question in our article using the most popular PVC constructions as an example.

Main phases of production of windows made of PVC and other materials

The window manufacturing process involves multiple steps. Here are the basic ones:

  Designing a construct.

  Cutting and armoring the profile. Filling.

  Welding window frames and sashes.

  Mounting fittings.

  Installing double-glazed windows.

  Checking the finished window for quality.

Now let’s take a closer look at each of the steps.

Designing

Sure enough, there are some standard designs used to make most of the goods, but some companies need custom windows, so in these cases, new designs are made. For this, they use special software. In this program, they enter the dimensions and other parameters of future products, such as type of profile, the shape of double-glazed window, the types and number of fittings, etc.

Once all the data are entered, the tool will automatically calculate the amount of material required to produce a single unit and estimate the cost of the window. This considerably speeds up the design process and simplifies it.

Cutting and armoring

This is the stage where they work with the profile and cut the frames and sashes to the right size. A traditional piece of equipment used for cutting and parting is a double head saw that cuts from both sides at once. With this technology, you can achieve the exact cut geometry, which is especially important since the subsequent welding process makes the joints smooth and tight.

Once cut, they arm the profile, thus increasing its strength and insuring against deformation.

Condition of armoring:

  They use galvanized steel. Its thickness for standard window sizes is 1.4-1.5 mm or higher for larger products.

  The reinforcement steel should have a regular n-shape and a bend at the sash. 

  The workpiece should be reinforced solidly, from edge to edge.

  The reinforcement steel must have a regular n-shape and have a bend at the sash.

Milling

This is the stage where they drill holes to install fittings, fasteners, condensate drains. Special attention should be paid to drainage devices that automatically drain water from the construct into the outside environment.

Welding

After milling, the workpieces are sent for welding – typically on a 4-head welder (although other types of equipment can also be used). The welding is required to heat the profile edges to the melting temperature of the material used, which is 230-260⁰C (440-500 ℉) for plastic. Next, they joint the edges.

A four-head unit helps you to connect all four corners simultaneously so that the frame geometry is close to perfection. Once welded, the construct is conveyed via a traveling belt for deseaming.

What is important is that seam durability should be close to that of the base material. For this, they check the corners for rupture. There are standards for each profile thickness, so it is best if the figures are twice as high as the standard ones.

Installing seals and fittings

Next, they proceed to the installation of fittings and seals. The latter is just as important as other window elements. Heat and sound insulation – the main characteristics for all windows – depends on the quality of the seals and their installation. You need to ensure that the seals retain their properties when exposed to extreme temperatures.

Through fittings, we open and close windows, install mosquito nets, and ventilate the room. So, the service life of the window depends on the quality of its installation, because the fittings break down the fastest.

In addition to the basic fittings, you can also add:

  Handle rotation lock.

  Anti-burglary elements: locking pins, strikes, etc.

  Handles with locks to prevent children from falling out.

  Step openers, etc.

Installing double-glazed units

Not only window glass helps to provide visibility and limit airflow from outside, but also to save energy. For this purpose, double-glazed units with a tin-silver coating are produced. The glass surface is first coated with a composition, then the glass is installed, and then argon is injected into the air chamber. For conventional windows, the production task is somewhat simplified, which lowers the price.

If the insulated glazing unit is installed incorrectly, the sash may be skewed, which will affect the service life and quality of the functions. During installation, the insulating glazing must be properly wedged with welted inserts and laying. Wedged glazing units are fixed by means of glazing beads.

In the final stage, the finished product is subjected to quality control and shipped to the customer.

Based on this information, we can conclude that this is a complex, multi-step process, requiring the qualifications of workers and the use of modern equipment. Following the technology guarantees a good quality of the final product.

5 Interesting Facts About the Gulf Canada Company

5 Interesting Facts About the Gulf Canada Company

Have you heard about the Canadian oil and gas giant? Originally known as British American Oil, Gulf Canada has been in business since 1906. For over 100 years, it has been supplying the country with energy resources. Still, it is less famous than Chevron or Shell. Outside Canada, this brand is mainly familiar to oil industry experts. 

Still, the company has a fascinating history. The story of its evolution is also confusing due to multiple mergers and acquisitions. There are so many names and locations. Here are five essential facts about the company and its activities today. 

  1. Many Names, One Company

This energy provider has been named differently over the many decades of its existence. This causes a lot of confusion, and consumers are understandably puzzled. Let’s begin with the origins. Originally, in 1906, Gulf Canada Resources Limited was incorporated as the British American Oil Company Limited. 

Over the next 60 years, its name was unchanged. Then, the British American Oil company limited was bought by an American corporation. This buyer was Gulf Oil Corp. The result of the merger was called Gulf Oil Canada Limited. 

So, what about Gulf Canada Ltd.? you may ask. This name became official 9 years later — in 1978. In another 9 years, in 1987, the name was changed once more. The company became known as Gulf Canada Resources Limited. Today, it is a giant with diverse interests. They go far beyond oil. The brand distributes natural gas, distills spirits, produces pipelines, and sells various forest products. 

  1. Was There Anything British about the British-American Oil Company?

Hardly! The founder of the company was born in Welland, Ontario. Albert Leroy Ellsworth born in 1876 established his firm in Toronto, across the ocean from the UK. By that time he had worked at a refinery in New York for 9 years. 

The company was officially registered on October 17th, 1906. Its first office building was at the corner of King and Yonge Streets in Toronto. As for the ‘British’ in the name… We have not been able to find any connections. 

  1. The Little Egypt Bump Controversy

Big corporations are known to cook their books time after time. Do you remember Enron? The Little Egypt Bump was the name of an accounting strategy that caused quite a stir. In 1985, the company used it to make a few corrections to its reports concerning the purchasing activities. The trick did not go unnoticed. 

The corporation was motivated by its desire to take advantage of the national tax legislation. The illicit accounting behavior allowed it to circumvent the rules that applied to partnerships. This caused a scandal so big that the head of the opposition John Turner made a dramatic official announcement. 

In Parliament, the politician declared that the company had deprived local taxpayers of 1 billion dollars. This loss equaled the lost tax revenue. However, other sources claimed the cost was half as big. The former federal deputy minister of finance was alleged to have been involved. He had left his position in the government to work alongside the Reichmann family during the negotiations.

  1. Why Did the Canadian Gulf Company Disappear?

Canadian Gulf Company was once a subsidiary of the Gulf Oil Corporation. Until 1956, it operated independently. Then, it was merged with British American Oil. In exchange, the former subsidiary gained a controlling interest. The result of the merger was a giant. It became the second-biggest producer of oil and the biggest holder of gas reserves in the country. 

  1. In How Many Countries Can You Find Gulf’s Products?

The geographic coverage is truly impressive. The company has been working on its brand identity for over 100 years. At the moment, you may find its products in over 100 countries. Globally, it is one of the oldest and most famous producers of oil and related products in the world. The brand is committed to development and growth, which is reflected in its impressive expansion.

Gas stations with the company’s recognizable orange logo are found on different continents. The brand is also famous for its support of motorsport and the Le Mans 24Hrs. The sponsorships include race teams like the famous Aston Martin Racing Le Mans. 

The Bottom Line

Admittedly, Gulf is among the biggest energy brands in the world. Its history is rich, and the future is robust. The company is still growing and looking for more partners and new territories.
