The manufacturing process of cookware involves a series of carefully orchestrated steps that transform raw materials into high-quality, durable, and aesthetically pleasing cooking utensils. It encompasses several stages, each contributing to the overall quality and functionality of the finished product.

Stage 1: Raw Material Preparation

The journey begins with the procurement of high-grade raw materials, including stainless steel sheets, aluminum ingots, and various components such as handles, lids, and gaskets. These materials undergo rigorous inspections to ensure they meet the specified standards for purity, composition, and strength.

Stage 2: Forming and Shaping

The raw materials are then transformed into the basic shapes of the cookware pieces. This stage involves various forming techniques, such as:

  1. Stamping: Stamping utilizes a press to stamp the sheet metal into the desired shape, such as the body of a pot or pan.
  2. Roll Forming: Roll forming continuously rolls the sheet metal through a series of rollers, gradually shaping it into the desired form, such as a cylindrical canister or a rectangular baking sheet.
  3. Deep Drawing: Deep drawing stretches a flat sheet of metal into a cup-like shape, such as the bowl of a pot or pan.

Stage 3: Welding and Fabrication

The formed components are then joined together using precision welding techniques, such as TIG (Tungsten Inert Gas) welding or MIG (Metal Inert Gas) welding. These techniques create strong, leak-proof welds that ensure the integrity of the cookware. Additionally, handles, lids, and gaskets are attached using appropriate welding or mechanical fasteners.

Stage 4: Polishing and Finishing

To achieve a smooth, shiny, and hygienic surface, the cookware undergoes a meticulous polishing and finishing process. This may involve vibratory tumbling, centrifugal polishing, or manual polishing using abrasive materials. The polishing removes imperfections, enhances the appearance, and prepares the cookware for subsequent steps.

Stage 5: Cleaning and Sanitization

To ensure the safety and quality of the cookware, thorough cleaning and sanitization are essential. This involves washing the cookware with detergents, rinsing with hot water, and subjecting it to disinfection processes using appropriate chemicals. These steps eliminate any potential contaminants that could affect the safety of food prepared in the cookware.

Stage 6: Quality Control and Testing

Prior to packaging and shipping, the cookware undergoes rigorous quality control measures to verify its integrity and performance. This may include leak testing, pressure testing, dimension checks, and visual inspection to ensure that the cookware meets the highest standards of quality and functionality.

Stage 7: Packaging and Shipping

The inspected and approved cookware is then carefully packaged using appropriate materials and methods to protect it from damage during transportation. The packaging ensures that the cookware arrives at its destination in pristine condition, ready for immediate use.

How do you manufacture cookware?

Stainless steel pots are the most common cookware products in our daily lives as they never get rusted, aged, or damaged. They are durable, healthy and economic in comparison with the other pot types

Stainless steel pots are manufactured by the technology called “deep drawing”. For this, you need to manufacture circle blanks from stainless steel. This operation is manufactured either by a mechanical eccentric press that cuts circles from sheet metal or you can use a circle cutting machine to cut the corners of square sheet metal to turn it into a circle. The first way is much faster but the second way is much cheaper. The diameter of the blanks determines the diameter and the depth of the pots. The bigger the diameter of the metal circle sheets, the bigger the pots will be.

Circle blanks cut from aluminum sheet

How is cookware manufactured?

After the circle sheets are prepared, the process continues with the second step: Drawing or Deep drawing. Drawing is a technological process, where the metal circle sheet transforms into another object with a die pair. The same operation is called “Deep drawing” when the depth of the new object exceeds its diameter.

For drawing or deep drawing, you need a hydraulic press, powerful enough to draw the metal sheet circle into a pot. The operator puts the metal circle sheets between the dies and starts the process. The upper plate also called “the pressing plate” starts to come down and meanwhile the downside plate also called the cushion cylinder starts to go up. the male die starts to shape the sheet metal circle into a pot. If the depth of the pot is not bigger than the diameter then, this operation is called “drawing”, otherwise it is called “deep drawing”

The Hydraulic press for drawing or deep drawing can be of various powers starting from as small as 40 Tonnes up to 4000 Tonnes for big parts such as reservoir tank caps.

160 Tonne hydraulic drawing press

How do you manufacture cookware?

Before this process, the operator needs to use a lubricator on the sheet metal circles to reduce the friction between the sheet metal and the die sets. The insufficient use of lubricator between the surfaces that face friction may lead to production failures such as tears or cracks.

The process of drawing may take up to 1 min depending on the circle diameter and product geometry complexities. After each cycle, the operator needs to take the part out and put a new metal sheet circle in between the dies for a new cycle.

Hydraulic drawing press at work

Drawing presses have accelerated the production of cookware in many folds as before the hydraulic drawing presses most of the cookware was being manufactured in some very inefficient ways including eccentric presses (this led to so many product failures as the speed of the process is not controllable)

After the cycle ends, the operator collects all the deep-drawn parts and prepares them for the next step: Degreasing

Deep drawing sheet metal parts

The step after drawing or press forming is actually “edge cutting and trimming” but as the parts are greased before the drawing operation, this left grease on the parts causes problems during the edge cutting operation. In an edge cutting operation, the part is fixed on a mold and a pneumatic cylinder presses the part from above to avoid any movement out of the cylinder axis. After that, the part starts to rotate with the help of an electric motor in the edge cutting trimming machine.

During that rotation, if there is still grease on the part, the upper pneumatic cylinder may not keep the part in its place and even if the mold in the part rotates, the part may stay still and this avoids any cutting or trimming operation. So, as EMS Metalworking Machinery, we advise degreasing the parts before they go on to the edge cutting operation.

Edge cutting trimming beading curling

The parts that are manufactured with a deep drawing press, have some rims on them, which need to be removed. These edges are usually sharp, uneven, and dangerous by handling. For this operation, we design edge cutting machines for round sheet metals or “edge cutting and trimming machines” as known in the industry.

Edge cutting and forming or trimming machine for round sheet metal parts

The stainless steel or aluminum pots are put on the male mold of the edge cutting machine. The upper mold, fixed on the tip of the pneumatic cylinder moves down to fix the part and the part starts to rotate with the help of the AC electric motor in the machine. After the starting of the rotation, the cutting tool (shown on the right side of the photo) starts to move to the rotating part and the cutting tool gets into contact with the part exactly at the point, below which needs to be removed.

The cutting tool cuts the part in less than half a second and the cut circle falls down apart from the part itself. This operation is called “edge cutting”. After this edge cutting, companies may require to have cookware products with more clean and even edges. For this purpose, the same edge-cutting process may proceed to edge trimming with the upper side of the cutting tool.

The circular cutting tool of an edge cutting and trimming machine

This process, either “edge cutting” or “edge trimming” or any other special metalworking processes like “beading or curling” takes a maximum of 4-5 seconds. So from this point, an edge cutting trimming machine may work with 5-6 presses together and 1 machine can cut the edges of the round sheet metal parts that are being manufactured by 5-6 presses at the same time.

Below from the video, you can see the speed of an edge cutting machine that does cutting and then beading inside in less than 5 seconds per cycle

Edge cutting trimming machine at work

Edge cutting machine is the last metalworking operation on the cookware production line, that changes the shape of the part. After this point, the pot has its final shape and is ready to continue with polishing or wiping.

Polishing machine for inside and outside surfaces

Most of the stainless steel and aluminum cookware we use have fine finishing and this fine satin finishing is done by polishing machines

Polishing machines are metalworking machinery that does not change the shape of the parts. They polish the inside or outside surfaces of the pots, pans, kettles, or other stuff by using some polishing abrasives and materials.

This operation can be organized in such a way that a single pot may go through 3-4 or even higher steps of polishing. The number of steps is determined by the finishing quality.

Our polishing machines can be with 1 or 2 polishing heads for easier finishing requirements but can also be equipped on a rotating table when there need to be more than 3 polishing stations. Polishing stations can be equipped with polishing compounds that can remove the deep marks, scratches, and heavy marks. You can polish cooking utensils, cutlery, kitchen sink, pots, pans, and even automobile parts.

Polishing machine for the outside surface of a stainless steel pot

Piercing and riveting the handles to cookware

After we polish the cookware with the necessary compounds, the next operation is piercing the edges of the pot and riveting handles to those pierced holes. The rims of the stainless steel pots are pierced on a punching machine where 1 or 2 holes are pierced at the edge of the pot. The holes are used to rivet the handle to the pot later.

Riveting is a fixing operation, applied on sheet metals. A rivet is a fixing nail with 2 parts: 1) Rivet body and 2) Mandrel. Rivet’s body goes into the pierced hole and is deformed so that it cannot move back again

After the riveting operation, you can have the products go through some washing with chemicals to clean them from the oil and dirt. When the parts are cleaned, they can proceed to packaging and to the market shelves for the customers

  5. Assembly and packaging: Once the milk cans have been cleaned and finished, they are assembled with any necessary accessories, such as lids and handles. The finished milk cans are then packaged for shipping and distribution.

Overall, a milk can manufacturing line requires a range of specialized equipment and expertise in order to produce high-quality milk cans that are both functional and visually appealing.

1.) Milk cans need to have stainless steel sheets to perform cylindrical bending. Those round parts are welded in order to form a hollow cylindrical shape. The sheet thickness of milk can vary from 1 mm to 2 mm depending on the can volume.

2.) After the round bending operation, the part needs to have a cone shape and this cone shape is carried out by a rolling spinning machine for cold forming of sheet metals. The rolling spinning is a sheet metal forming operation used to form parts made from sheet metals into different geometries. In our case, the spinning rolling is performed by a PLC-controlled servo motor. Servo motors have high precision that helps to have a unique forming quality. Our spinning rolling machines are controlled by 2 servo motors, one of which controls the X-axis movement, the other Y, where there won’t be any change in the Z-axis.

3) After the spinning rolling machine, the part is taken to edge cutting and trimming to cut/trim the edges or bend/curl them inside/outside. These operations are needed to fix the upper part of a milk canister to the bottom part

4) After the rolling spinning and edge-cutting trimming operations, the milk can is taken to the polishing part to have a mirror effect on the inside and outside.

The milk canisters’ upper part shaped in a spinning rolling machine for cold forming

The milk cans or milk canisters are also called milk jugs. The most widely used milk jugs are made of stainless steel 304. The sheet metal thickness for the milk cans and jugs are 1 and 2 mm respectively.

Dairy Farm Equipment Manufacturing Machinery

Milk can manufacturing lines are typically designed for the production of milk cans made of stainless steel or aluminum. The process involves several stages, including cutting, bending, welding, polishing, and painting.

The production line usually starts with sheet metal cutting machines, which are used to cut the metal sheets into the required shapes and sizes. These machines can be manually operated or automated, depending on the production volume and complexity.

The next stage is bending, which involves using a hydraulic press brake or a roll bending machine to shape the metal sheets into the desired form. This stage is critical as it determines the final shape and dimensions of the milk cans.

After bending, the metal sheets are welded together to form the body of the milk cans. This process can be performed using various welding techniques, including TIG welding, MIG welding, or spot welding.

Once the milk can bodies are welded, they are sent to polishing machines to give them a smooth and shiny finish. These machines use abrasive pads or brushes to remove any surface imperfections and create a uniform surface finish.

Finally, the milk cans are painted using a powder coating or spray painting process to give them a durable and attractive finish. The cans are then inspected for quality control before being packaged and shipped to customers.

Milk cans or canisters made of stainless steel can be manufactured by our machinery

The milk cans have different geometries as shown above. Our deep drawing presses can draw long parts and then the edge cutting trimming beading curling wrapping and crimping machine can cut and curl the sheet metal edges of the milk cans. After these operations the milk can is placed on the polishing machine to polish inner and outer surface of the milk can.

Milk cans can be made from various materials, including stainless steel, aluminum, and plastic. However, stainless steel is the most common material used for milk cans due to its durability, resistance to corrosion, and ease of cleaning. Stainless steel milk cans are usually made from high-grade austenitic stainless steel, which is resistant to corrosion and can withstand high temperatures and pressures. Aluminum milk cans are also used in some parts of the world, but they are less durable than stainless steel and are prone to corrosion. Plastic milk cans are lightweight and easy to handle, but they are not as durable as metal cans and are not suitable for high-temperature applications.

Stainless Steel for the Milk Can

Stainless steel milk cans are typically made from a type of austenitic stainless steel called 304 or 316. These grades of stainless steel are known for their excellent corrosion resistance, high ductility, and good formability. They are also non-reactive, which means they do not interact with the milk, ensuring the milk remains safe for consumption.

The manufacturing process for stainless steel milk cans typically involves sheet metal forming techniques such as deep drawing, bending, and welding. The sheet metal is first cut to size and then formed into the shape of the milk can using a deep drawing press. The top and bottom of the can are then formed separately and welded to the body of the can. The seams are then ground down and polished to give a smooth finish.

Aluminum milk cans are also made using sheet metal forming techniques, but they are generally less durable than stainless steel milk cans. Aluminum is a lightweight material that is easy to handle, but it is prone to corrosion and is not as strong as steel. Aluminum milk cans are typically made using the same manufacturing processes as stainless steel milk cans, but with different welding techniques that are better suited to the properties of aluminum.

Plastic milk cans are typically made using injection molding techniques. The plastic material is heated and injected into a mold that is shaped like a milk can. Once the plastic has cooled and solidified, the can is removed from the mold and any excess material is trimmed away. Plastic milk cans are lightweight and easy to handle, but they are not as durable as metal cans and are not suitable for high-temperature applications.

Otherwise, the sheet metal may tear easily.

A polishing machine for internal polishing of stainless steel pots typically works by using rotating polishing heads and specialized polishing compounds to achieve a smooth and shiny surface finish on the inside of the pot. Here are the general steps involved in the process:

  1. Load the pot onto the machine’s chuck or fixture.
  2. Start the machine and adjust the speed and pressure settings according to the pot’s size and the desired surface finish.
  3. The polishing head moves inside the pot, applying polishing compounds to the surface.
  4. The rotating spindles of the polishing head polish the inside of the pot as it rotates on the chuck.
  5. Once the internal polishing is complete, the machine automatically stops and the polished pot is unloaded.

The specific details of how the machine works can vary depending on the model and manufacturer, but the general idea is that the machine automates the internal polishing process, providing consistent results with less manual labor and effort. Some machines may also have specialized features such as automated compound application and cleaning systems to further streamline the process.

  5. Versatility: Hydraulic cylinders can be adapted to a wide range of deep drawing press configurations and sizes.

Conclusion

Hydraulic cylinders play a pivotal role in deep drawing presses, providing the powerful and controlled force required to transform flat metal blanks into complex three-dimensional shapes. Their ability to generate high force, offer precise control, and operate smoothly makes them essential components for achieving high-quality deep drawing results.

Hydraulic cylinders act in both directions. The actuator of the cylinder is the compressed hydraulic oil that is pumped by a hydraulic pump. The pressure here can go as high as 1000 bars. Hydraulic cylinders are manufactured of high carbon steel and the rod of the cylinder is made from stainless steel.

This rod surface has critical significance in the working of the press as it shall never get damaged. When the rod surface gets damaged or has some scratches on it, the cylinder starts to leak when the seal comes to this part and oil starts to leak out through these scratches. In order to avoid this, the rods of the cylinders are hardened by heat treatment and coated by Hard Chrome Plating.

Radial Riveting Machine

Radial Riveting Machine for Riveting of the Cookware
Radial Riveting Machine for Riveting of the Cookware

Rivets, that are used by a radial riveting machine, are small pieces of metal that are crushed into position between two harder pieces of metal. The resulting rivet holds the two pieces of metal together. Rivets can be made out of almost anything, but are usually made out of aluminum or steel.

A radial riveting machine is a type of mechanical press that is used to fasten two or more pieces of material together using a rivet. Unlike traditional riveting methods that involve hammering or squeezing a rivet into place, radial riveting machines use a rotary motion to form the rivet, creating a stronger and more secure joint.

Radial Riveting Machine

The process begins by placing the pieces of material to be fastened into the machine’s work area. A rivet is then inserted into the machine’s collet or chuck and positioned over the joint. The machine’s spindle rotates at a high speed, causing the rivet to spin and form a mushroom-shaped head as it is pressed into the joint. The rivet is then locked in place, creating a permanent and secure joint.

Radial riveting machines are used in a variety of industries, including automotive, aerospace, and electronics manufacturing. They are ideal for fastening materials that are difficult or impossible to join using traditional methods, such as curved or irregularly shaped parts. Additionally, radial riveting machines can be customized to accommodate different rivet sizes and materials, allowing for greater flexibility in manufacturing processes.

Welds are created when you melt two pieces of metal together, sometimes with a filler material. Brazing is when you take two pieces of metal with high melting point and join them by heating a small amount of metal between them which has a lower melting point. Brazes have problems when temperatures reach the softening or melting points of the brazing material, and they are not commonly used for modern cookware handles.

Screwed-on handles use a screw to fasten the handle to the actual cooking vessel. You typically only see this design on cheaper cookware or on high-end European cookware (which often use multiple stainless steel screws per handle). Some people think screws look tacky. Screws are cheap but effective, and you can tighten the screw yourself. If the screw rusts due to being made from a inferior grade of stainless steel, you can replace the screw yourself. However, this is usually a hassle since you have to find or make a screw of the correct length. Nevertheless, at least it is a user-replaceable part, unlike welds and rivets and brazes.

It’s possible to form the handle of cookware as an extension of the body of the cookware itself, such as with cast iron pans. While the resulting handles may be strong, the drawback is that the pan handle gets hot when used, as a result of being made out of the same, heat-conductive material as the body.

Judging by the paucity of welded handles in USA-made cookware, Americans seem to believe that rivets are more durable than welds, but that is a) not necessarily true, and b) it doesn’t necessarily matter. Depending on weld quality and rivet quality, either can be stronger than the other, but the real question is whether they are strong enough for kitchen cookware. We are discussing cookware, It doesn’t matter if rivets can be made stronger than welds if even a weld job is more than enough to get the job done–and welds can definitely get the job done. A lot of professional restaurant cookware vessels have no rivets, and they see far harsher conditions than cookware in residential kitchens.
