A reason this guide will make the entire process easy and simple for to understand.

It answers all questions you have about sheet metal cone fabrication – let’s dive right in.

What Is Sheet Metal Cone?

A sheet metal cone is a fabricated metal cone that is manufactured from different types of metallic sheets.

Sheet metal cone is made from either carbon steel, aluminum, stainless steel, or other alloys in the material.

The material of the sheet metal cone will depend on where it is going to be used.

The common thickness of your sheet metal cone ranges from  16 gauge and can go up to 4 inches thick.

You will use the sheet metal cone mostly in industries such as pipe reducers or increasers, chutes, and transitions.

Sheet metal cone

Also, you can use the sheet metal cone as funnels and hoppers.

For lightweight sheet metal cones, they are used in metal ductwork for ventilation.

Whereas, those made from heavy plates are used in metal ductwork for large manufacturing processes and steel mills.

Two types of sheet metal cones can be fabricated.

  • Truncated cones; this one is not a full cone shape.

It has two different diameters sizes at both ends and can be either concentric or eccentric.

Non-truncated cones; this type of cone presents a full cone shape.

What Are The Benefits Of Sheet Metal Cone Fabrication?

Fabricated sheet metal cone offers longevity.

This is because the design of your sheet metal cone design is specific for the intended use.

It means that your sheet metal cone can withstand more applications than are regular.

This allows your sheet metal cone to have a longer lifespan.

Also, the fabrication of your sheet metal cone makes it possible for one to choose which hardware materials they are going to use with it.

This is because when it comes to fabrication, you allow your sheet metal cone to be compatible with the existing hardware.

sheet metal cone fabrication

The sheet metal cone is very strong and durable despite its light weight.

Fabricating your sheet metal cone means you can come up with the best and most durable cone.

This is because one can choose the best material to fabricate the metal cone that will serve their needs.

Also, fabrication helps you to use older equipments or materials in the manufacturing of your sheet metal cone.

Some materials that are of the best quality might be no longer available or produced, one can use the old used ones to make their sheet metal cone.

This saves one a lot of time that would have been spent in hunting down the materials since fabrication will allow you to use the old available ones.

Also, fabricating your sheet metal cone helps one get the best quality of metal cone at a cheaper price.

This is because the cost of buying an already manufactured sheet metal cone is higher compared to if one fabricates it.

Also, when fabricating, you choose the materials you are going to use, and going for the best quality enables you to fabricate a sheet metal cone of high quality.

Fabricating of the sheet metal cone’s greatest advantage is that you get what you want.

You can make the precise sheet metal cone with your specifications of where to use it.

It also reduces wastage,  because you are sure that your fabricated sheet metal cone will fit where it is supposed to be used.

Unlike if one buys an already manufactured one, it may not fit hence leading to it being dumped and purchase of another one.

This leads to a wastage of time and resources in the purchase process.

What Are The Critical Stages In Sheet Metal Cone Fabrication Process?

Step 1: Critical Dimensions In Sheet Metal Cone Fabrication

Sheet metal cone dimensions

Sheet metal cone dimensions

The first and most critical stage in sheer metal cone fabrication is getting the dimensions.

The dimensions of the sheet metal cone will influence the size of your cone.

One needs to be very keen since the size of the cone will determine which hardware materials will be used and where they will be used.

Also getting the dimensions of the sheet metal cone can enable you to have a clue about the purpose of the sheet metal cone.

Having the dimensions will also give you an idea of the type of material you are going to use in the fabrication process.

This is the most important stage of sheet metal cone fabrication since it gives you an idea of the type of cone you are going to fabricate.

Getting the dimension of the sheet metal cone you are going to fabricate will guide you in choosing the best fabrication process that you are going to use.

With the dimensions, you can sketch down your sheet metal cone and visualize how it will be.

Step 2: Have Technical Drawing Before Sheet Metal Cone Fabrication

After noting down the dimensions of your sheet metal cone the next step is technical drawing.

Technical drawing of your sheet metal cone before fabrication is very important.

This step gives you a clear picture of your sheet metal cone.

It also helps you communicate efficiently with the fabrication team.

Also, the drawing is used and kept as a record in the planning process of your sheet metal cone fabrication.

The technical drawing step will save you a lot of time.

The reason is the drawing is easily interpreted and will communicate to you how the sheet metal cone needs to be fabricated.

This also reduces the chances of fabricating unwanted sheet metal cones since the drawings explain every aspect of it.

Also, the technical drawings will enable you to get approved easily when you apply for a patent.

It is easier to get patent approval when you have clear technical drawings than when you have a sketch.

Step 3: Choose Suitable Material For Sheet Metal Cone Fabrication

One needs to choose the most suitable material for sheet metal cone fabrication.

If you do not choose the right sheet metal, the product will fail during the manufacturing process.

Selection of the right metal will help you fabricate a sheet metal cone that will last longer in the area where you will use it.

Also, because sheet metal reacts differently to different forms of manipulation makes their selection very important.

The material you choose should be able to maintain its physical properties as well as strength during the fabrication process.

Choosing the right material will also improve your product’s function, quality as well as endurance.

Before selecting the suitable material for sheet metal cone fabrication, you should do detailed research on the available sheet metals.

The research helps you know the properties of the available sheet metals for fabrication.

From the information you get from your research, you can choose the best sheet metal for fabrication.

You can choose from a range of materials such as:

  • Stainless steel sheet
  • Copper sheet
  • Aluminum sheet
  • Brass sheet
  • Iron sheet
  • Galvanized sheet metal

Step 4: Have Layout Template For Sheet Metal Cone Fabrication

The layout template for sheet metal cone fabrication is very important.

It guides you in the fabrication process of your sheet metal cone.

This is because the template will guide you in the cutting and forming processes required in sheet metal cone fabrication.

The layout template will also give you the design of your sheet metal cone.

From the design, the layout will also give you an idea of the type of sheet metal cone you are going to fabricate.

Also, it helps you in choosing the right type of sheet metal that you need to use.

From the layout template, one can choose the best cutting technique that is appropriate for the sheet metal fabrication process.

Having a layout template will simplify the fabrication process and save time for production.

In addition, the layout template is very important since it helps you fabricate quality sheet metal cones.

Step 5: Cut Material For Sheet Metal Cone Fabrication

Cutting material for sheet metal cone fabrication depends greatly on the type of sheet metal cone you want to manufacture.

There are different ways in which one can use to cut sheet metal in cone fabrication.

The cutting methods include;

  • Laser cutting; here you use a lesser machine that uses a powerful laser that is intensified with a lens.

This cutting method is precise and also energy efficient.

Lesser cutting is suitable for thin and medium sheet metal gauges.

The lesser cutter is most likely to struggle in penetrating hard materials.

  • Waterjet cutting; here you use a high-pressure jet of water mixed with an abrasive substance to cut through your sheet metal.

This method is efficient when used to cut sheet metal with low melting points

The reason being they do not generate heat that could deform the sheet metal during the process.

  • Plasma cutting; here a plasma cutter creates an electrical channel of ionized gas.

This forms a jet of hot plasma that is easy to penetrate through thick gauges of sheet metals.

The method is not as accurate compared to the other cutting methods.

It stands out for being faster and more powerful with lower setup costs compared to the other cutting methods.

Step 6: Forming Material During Sheet Metal Cone Fabrication

Bending sheet metal to form cone

Bending sheet metal to form cone

This step is one of the major categories in sheet metal cone fabrication.

The groups of processes undertaken here can change the sheet metal without one having to cut into it.

We have various techniques used in shaping your sheet metal cone during fabrication.

The techniques include:

  • Bending; a machine known as a brake is used here.

Here one can bend the sheet metals into different shapes mostly Vand U shapes.

Also, it is possible to bend the sheet metal and get channels up to around 120 degrees.

Bending is an easy technique if you are using thin gauges of sheet metal in cone fabrication.

  • Stamping technique: this involves using a hydraulic stamping press that is equipped with tool and die.

Here you are not necessarily required to remove the material during the process of sheet metal cone fabrication.

You use stamping in specific tasks like drawing and curling on the sheet metal cone fabrication.

  • Spinning technique; the use of a lathe machine is improvised here.

The lathe machine rotates the sheet metal and presses it against a tool that is cone-like.

The sheet metal is fabricated into a cone.

The process resembles pottery spinning as well as CNC machining.

Step 7: Assemble Sheet Metal Cone

When you cut and form the sheet metal into a cone, it is the fabrication and forming process.

After doing this, one has to assemble and create the cone.

This is done by using common fasteners or other suitable methods.

The process is not considered a fabrication process but it is an important step in the manufacturing process.

The assembly process employs the use of bolts and rivets and screws.

Also, in the case where heat is required, welding is used.

Here a section of the metal that joins another metal section is melted.

After this, the two sections are fused to form a solid connection.

Welding is done if the sheet metal used in cone fabrication has very good weldability.

Step 8: Apply Various Surface Finishing Options

The choice of your surface finish on the fabricated sheet metal cone depends on its application.

Your fabricated sheet metal cone needs to have a surface finish.

The surface finishes give it a decorative feel and also enhance the electrical conductivity of your cone.

Also, the surface finish gives your fabricated cone a higher tarnish resistance as well as chemical resistance.

For your fabricated metal cone to be more durable and have higher electrical resistance, you have to give it the best surface finish.

Surface finishing options used are as follows;

  • Coating; is a cheaper method of providing protection to your fabricated metal cone and giving it an appealing finish.

You can use either water or oil-based paints to protect the surfaces of your metal cone against corrosion.

  • Electroplating; chemical baths are used to coat the surface of your fabricated metal cone.

The process is chemically intensive and is not just performed by anyone but only service providers that specialize in that field.

This process will improve your fabricated sheet metal cone durability, corrosion resistance as well as exterior appearance.

  • Heat treating; after fabricating your cone to its desired shape, one employs heat treatment on its surface.

This helps one procure the desirable characteristics in the material of your cone.

The method is also applied to do away with any residual stresses left during the manufacturing processes.

It also increases the wear resistance at the teeth surfaces as well as improves the strength of the underlying teeth.

  • Grinding; abrasive wheels are used to smooth out the surface of your fabricated sheet metal cone.

It, therefore, reduces the roughness of the surface of your cone during the machining process.

  • Brushing; you employ an abrasive belt or at times wire brush to achieve a smooth surface.

It also helps one remove surface imperfections and create a uniform and smooth surface finish.

  • Polishing; is an abrasive method that reduces the surface roughness on the fabricated metal cone after machining is done.

This increases the metal luster of your fabricated cone since reflected light is scattered less on smooth surfaces.

Also, this method is employed when you want to improve the surface anesthetics of your fabricated cone.

 Polished sheet metal cone

Polished sheet metal cone

Step 9: Test And Check Quality Of Sheet Metal Cone Fabrication Process

It is very important to test and check the quality of the sheet metal cone fabrication process.

The reason is, it will help you know if your fabricated sheet metal cones are of high-quality standards.

If the fabrication process is of high quality, it will save you a lot in terms of money and time.

The high-quality cones are durable and will serve you longer unlike those of low standards that will cost you since you will have to replace them now and then.

This also helps you have confidence in your fabricated cone to serve you for a longer period without failure.

Several tests are done to check the quality of your sheet metal cone fabrication process.

The tests include the tensile test, the hardness test, and the fatigue test.

If your fabrication process passes all three tests then it means that you are fabricating a high-quality sheet metal cone.

Always fabricate your sheet metal cones using manufacturers that are ISO9001:2015 certified for quality cones.

When ISO certified, it means that all the processes that are undertaken in the fabrication of your sheet metal cone are up to standards.

If all the processes ate up to the required standards, then it means you can manufacture very high-quality sheet metal cones.

What Are The Common Challenges During Sheet Metal Cone Fabrication?

The cost of fabricating the sheet metal cone is very high.

This is simply because you require skilled personnel to fabricate for you the cone.

Also, one requires excellent material quality to be used in the fabrication of the sheet metal cone which is also costly.

In addition, the tooling and equipment cost for the fabrication of the .metal cone is also high.

Fabricating the sheet metal cone takes a lot of time.

One is required to be very precise and keen with the drawing and when it comes to cutting the required measurements of the cone.

The process of fabricating the sheet metal cone itself has nine steps one has to keenly follow for them not to mess up.

Due to the complexity of the fabrication processes, it is easy for one to make a mistake.

Mistakes being common lead to a lot of wastage due to the production of unwanted sheet metal cones in large numbers.

If one is not keen on the bending stage, the sheet metal cone is likely to come out when its thickness is uneven.

When it is uneven, it will have a negative impact in areas where you are going to use it and may lead even to the breakdown of machines parts that are connected to it.
