Production of ventilation: how to fix it and what to

Nowadays, none of the existing buildings can do without a simple or complex ventilation system. If earlier in the walls they simply made holes to ensure more or less acceptable air circulation, then at the moment it doesn’t satisfy either the building or sanitary and hygienic requirements.

The production of ventilation ducts, with its proper organization, can be a good business. We will talk about this in this article.

Production technology

1. The simplest method is the production of rigid (round, square and rectangular) air ducts from aluminum or galvanized steel. Such pipes are most often used for arranging ventilation in large buildings: restaurants, shopping and commercial centers, pre-school, educational and medical institutions, offices, etc.

Products are cheaper than analogs made of plastic, do not corrode, are fireproof, they are easily and quickly assembled.

1. It is more difficult to make your own flexible (usually round, sometimes square) plastic or aluminum ducts. They are used, as a rule, in rooms that do not have a very large area, for which galvanized canals are not suitable due to their size.

Such air ducts are used in various industrial plants, where it is necessary to remove constantly hot air or volatile harmful substances. For this system are equipped with exhaust hoods with powerful fans.

Note! Experts say that it is desirable to start your business with the manufacture of flexible ventilation ducts, despite their high cost and complexity of production. At the moment, this type of system is most in demand. Based on this, its faster and easier to sell.

The direct production of the ventilation system is carried out on special profile-bending machines. In modern workshops, this process is automatic.

One of the main tasks in business planning is a competent choice of efficient and high-quality equipment, which will ensure uninterrupted production and sales of finished air ducts.

      Equipment used for the manufacture of ventilation elements

Here is a list of the necessary equipment for the production of air ducts and ventilation.

1. Spiral-wound machines.
2. Systems for cutting metal sheets.
3. Machines for cutting profiled metal.
4. Analogs for the production of segmental taps.
5. Machines for seam, spot and cold welding.
6. Rolling machines.
7. Zigovochny units.
8. Automatic lines for the manufacture of rectangular channels.
9. Cutting guillotines.
10. Bending machine.
11. Units for arranging stiffeners.
12. Seam-sedimentary and seam-rolling analogs.

You can do without something from this equipment, and some units will have to be purchased.

1. First of all, it is necessary to purchase units for cutting metal - guillotine shears. If you are not confused by the rather high price, you can replace them with a system that produces plasma cutting of metal.

Such machines are particularly accurate and have high performance. They give the chance to carry out curvilinear cutting of sheets of metal.

1. For the manufacture of square and rectangular ventilation channels are used sheet and bending machines (hydraulic or manual). For circular ducts - spiral-wound counterparts. They make it possible to make pipes with a diameter of 8/250 cm.

Note! It is worth all the equipment quite expensive. However, you can purchase used machines for the production of ventilation. It should be remembered that, since they have partially already exhausted their resources, their productivity and efficiency will be lowered.

1. Manufacturing of accessories (adapters, plugs, elbows, etc.) occurs on the seam-rolling machines or on hydraulic machines for the manufacture of segment mates.
2. Special machines make it possible to make high-quality welded joints of round and rectangular sections of channels. In the case of spot welding, so-called “welding tongs” are used. When cold welding is used, pulling machines are required.
3. For the process of manufacturing the edges of the channels (flare, roll-up of folds, profiling), manual or electromechanical zigochnye units are necessary.

What to take into account

First of all, when opening this business, it is necessary to thoroughly study what the market needs, to determine what specific products customers need.

Consumer demand study

1. Before you start the production of ventilation and air conditioning systems, you should monitor consumer demand in your area. For example, at least flexible duct types are more expensive, but they (on average in Russia) are more popular.
2. Note that the air exchange rate depends on the shape and cross section of the channels.
3. These parameters also affect the noise level of the system, which is very important for consumers.
4. The instruction notes that ventilation ducts with a rectangular cross section and its larger volume are more efficient than analogs of a circular configuration, with the same volume.
5. However, it is much easier to install round ventilation networks, since their elements are mated with special clothespins.
6. According to statistics, rectangular and rounded air ducts of solid types of materials, having a wall thickness of 0.5 / 1 mm, sell equally well, and the technologies of their production are similar.

Cost of production of ventilation systems

Before you start such a production, you need to make a good business plan for the production of ventilation. To do this, you should think about all the advantages and disadvantages of the future enterprise.

It is necessary to begin with financial expenses.

1. For example, a line for the manufacture of round ventilation ducts will cost, on average, 57 thousand dollars. Analog for square and rectangular ducts will cost a little less - about 46 thousand.
2. If you want to establish the manufacture of pipes for ventilation with different dimensions of the section, you will need 103 thousand dollars. Here you should think about how to buy machines used for the production of ventilation.
3. It should be noted that the average profitability of such production is 50%.
4. According to the statements of professionals, the running meter for consumers will cost 4/100 dollars, based on the pipe section.
5. Provided that the workshop will be “five days” in one shift, then your net monthly profit will be equal to 23500/27000 dollars.
6. If we set up manufacturing of related products, for example, the production of ventilation grilles, then the investment will pay off after about 6 months.

About prospects

1. You can start your business with a small production. For example, manufacturing fasteners, connecting and locking accessories (nipples, plugs, inserts, taps, "umbrellas"). Defective products and waste will be suitable for their production.
2. Gaining momentum and accumulating funds, you can expand the business through the manufacture of the air ducts themselves.
3. For the manufacture of pipes there is no need to hire highly qualified personnel. Employees can be trained on site in a few days. So you will save on equipment and salary.
4. Expanding your business, you can hire more cool staff, such as engineers and designers, to produce, plan, and install ventilation systems for customers from scratch.

Conclusion

Now there are many opportunities to build their own, albeit initially small, business. The manufacture of ventilation systems is a very good option.
