Uses of sheet metal machinery range from making panels for packaging to making parts for machines. These machine tools have also helped make various medical equipment and various mechanical tools. But the sheet metal machine we know today has gone through huge changes since its invention. In this article, we will see how the sheet metal machines evolved and became what we know it as today.
Introduction of the punching machine
Humans have been engaged in sheet metal works from centuries now. In the prehistoric times, need for making sophisticated tools, vessels and pieces of jewellery was one of the reasons which triggered the invention of sheet metal machines. Punching Machine is considered as one of the very first sheets metal machine. It is still used as a manual tool in small-scale industries to punch holes in metal sheets. Punch machine was used to drill holes in metal sheets using manual force.
Folding/Bending of metal sheets
When just punching hole was not enough for making a complex tool, bending of metal sheet was introduced. In the beginning, sheets were placed between a set of rolling cylinders. These cylinders clamp on sheets and form the bend. If the desired bend is not obtained, the sheets are passed through the cylinders again. This process continues until the desired bend is obtained. Modern technologies have made this machine to evolve into Magnetic Bending Machine in which electromagnets are used to form the bending.
Since the tool to be made from metal sheets varied, it was not possible to work with just folding and punching. As the use of metal products increased, there was a need for the introduction of a process that would allow cutting of large metal sheets. This was made possible only after the introduction of pivoted scissors. This enhanced the production process. Shearing Machines are still being used widely in today’s industry. These modern machines tools are made from high carbon and chrome steel blades which provide higher stability while performing the operations.
Modern machines tools
Sheet metal machines have evolved far from its predecessors. Introduction of steam power was the first turning point for these machines. Use of steam power replaced manual handling of tools and provided far better performance with a high rate of production. Next leap was the introduction of electric control machinery such as Electric Operated Slip Roll. The electric control not only eased the usage but also helps increase the productivity of the system. At small scale production plants, hand and foot operated machinery are still used but demand for a higher rate of production is forcing the replacement of traditional machines with modern machines.
International and local transport has grown considerably due to globalization and internationalization. There has been a global increase in dependency on commodities manufactured from low wage countries such as China, India, Africa and Asian nations. This has driven the demand for better shipment.
The invention of containership by Malcom Mclean’s in 1956 was perhaps the most important innovation in the transport sector. Bulk and sensitive commodities are packed and sealed in strong durable steel or aluminum boxes. These were then loaded on trucks, ships and trains for transportation.
The shape of the container allows easy stacking on top of each other. Since they are manufactured from high strength materials and locked, they are intrusion free. They also have identification number allowing for easy tracking via GPS and RFID.
Essential Parts of a Container
Standard containers are manufactured from steel or aluminum. Their shape, sizes are standardized to allow easy handling and transport.
Steel containers are 20, 30 or 40 feet long, width of 7 and 8 ft and 8, 8 ½ and 9 feet high. The side and end walls are manufactured from paneled sheets. The frame is specially designed to withstand weight of other stacked containers on top. One end has door hinges, panels and locking bars.
Aluminum types are made of steel frames while the sides, front, back, roof and bottom are made with high strength durable aluminum.
Machines used in container manufacture
The container manufacture process utilizes a great deal of sheet metal machinery. First they are cut to their specific dimensions using the shearing machine. This device is sturdy and has the capability of cutting heavy gauge plates in a guillotine manner.
Square, rectangular and round grooves are then made on the flat materials using a specially designed heavy duty press brake. The machine is fed with material and it forms the square corrugations.
The roof panels are made pressing using a specially designed press brake machine. This device punch presses the plate against the die to form the intended shape.
The floor frame is then made by cutting the plate using a shearing machine and these are folded using a press brake machine. This machine folds the material forming a U shaped bracket. A series of these brackets are welded to form a very strong base.
The door, sides and other parts are also fabricated by cutting the plates and square tubes using shearing equipment, folding the sheets using press brake and welding the parts. Fastening holes are also drilled on all parts.
Quality issues in sheet metal working
The containers must be made from good quality materials that don’t rust or corrode when exposed to harsh sea environment. The joints and other parts must be properly sealed to protect the commodities being transported.
Rising containerization process in international trade
The container market has continued to grow rapidly. In 2012, the global container fleet was 32.9 million TEU and 34.5 million TEU in 2013. This growth is expected to continue due to their global acceptance and high demand.

Various applications are applied like bending, curling, piercing, deep drawing etc. Automation makes the power press faster, which is the main requirement of production industry now a day to save money and time. Thus research and development is going on for these heavy machinery to make them more effective for the functions, high production, least wastage of raw material and easy operation with best protection guards to secure the operator’s life along with technical enhancements like speed of the power press, width of the stock etc. continuous feed of the stock is a complex process which requires to be streamline and easy to be done in proper manner. Accuracy is required for better production through power press; otherwise it can create the defective piece leads to wastage and production loss. It also has a great advantage when you require more complex shapes formed into the sheet metal. It is defined as mechanical, hydraulic and pneumatic. It consisting mechanical parts, clutch and brake assemblies, electrical systems, tooling or dies, safeguarding controls, material handling etc. hydraulic power press is designed on Pascal’s principle that pressure throughout a closed system is constant. OSHA and ANSI standards are defined for safety measures.
Safety Controls for Power Press
It is a machine needs to handle carefully by skilled operator with proper training. A little mischief can lead to a serious accident if not taken care. Thus need to take care of hands, fingers, arms and other body parts while operating the machine. Proper safeguards, frequent inspections, employee training and regular press maintenance are vital to the prevention of any injuries. The operator must take care where stock is inserted, held or withdrawn by hand. It is designed in such a way which eliminates the possibilities to place any body parts in contact with hazardous moving parts. Operator must know the importance of safeguards and never remove or alter with the safeguards. Extensive training on different types of press machine can make the person more skilled to handle power press efficiently without any injury.
Sheet Metal Machine
Machine tools are the devices used to cut, drill, press, and shear the hardened materials into specific forms. Metal Forming Machine are used to cut, press, bend and form sheet metal into different shapes and sizes. Various metals are used for this process. Aluminum, brass, copper, steel, tin, nickel etc are used for various automobile, medical and other industries.
Types – Sheet Metal Machine
Sheet Metal Machinery are applied in different applications and industries. Several types of power press are available like C type power press, pillar power press, hydraulic, punch press, H type power press. Hydraulic press use hydraulic cylinder to generate a compressive force uses hydraulic equivalent of a mechanical lever. Hydraulic power press is commonly used for hydroforming.
Sheet bending is a type of sheet metal machine use to form heavy and large right angle and curved folds on the sides of the trunks. Steel body fly press is also a categorical bending tools used for particular press work with higher centre distance, accuracy and efficiency. Arbour press is used for general engineering workshops, automobile workshops and garages. Other types are swaging, small and imported sheet metal equipments are used for various industrial applications.
Applications – Sheet Metal Machine
Power press are widely used in various industrial purposes in automobiles and other industries to acquire enormously high precision press operation, table and ram are aligned to each other. Hand operated sheet bending device has cast iron body, complete with handle, bending bar and bending blade to curve folds on the sides of the trunks. Hand operated rack and pinion type arbour presses are used for driving mandrels in and out of work also used in inserting and removing bushes, bearing etc. Press brakes are used in many different forming jobs with the right die design like V dies, rotary bending dies, acute angle dies, radius dies etc. In a mechanical press brake, energy is added to a flywheel with an electric motor.
A clutch engages the flywheel to power a crank mechanism that moves the ram vertically. Accuracy and speed are two advantages of the mechanical press brake. Hydraulic press brake operates by means of two synchronized hydraulic cylinders on the C-frames moving the upper beam. Press brake is a fundamental tool to get steel forming industry.
